chapter 1 introduction to the tme ebk in general terms, thermal management is a combin ation of temperature sensing, fan control and the algorithms or transfer functions that map temp erature to fan speed. thermal management is a critical, system-level function that needs to ensure that all compone nts in the system operate within safe temperature limits, while at the same time minimizing power consumption and acoustic noise. typical solutions for thermal management include multiple devices such as cplds, mixed-signal asics and/or limited-functionality and inflexible discrete devices. thermal management solutions need to be flexible enough to interface with many kinds of both digital and analog temperature sensors. to maximize efficiency, they must also be able to drive a multitude of fans independently. finally, thermal management solutions must have e nough intelligence built in to reliably control the cooling systems autonomously, independent of a master control processor in the event that communications are lost or the master c ontrol processors fail or go offline. the psoc? 3 architecture enables a flexible and uni que method of thermal management in a single chip, combining analog sensing capabilities for any kind of analog temperature sensor such as remote diodes, thermistors, resistance temperature detectors (rtds), etc. ps oc 3?s versatile digital resource pool enables the integration of multiple i2c bus interfaces, capture timers and even full-custom logic to support interfaces to a wide variety of digital temperature sensors such as i2c based, pulse-width-modulated (pwm) based and other proprietary seri al interface digital temperature sensors. psoc 3?s unique cpld-like hardware blocks are also used to implement a full hardware closed loop fan control system for high reliability system s that require zero intervention from firmware running on the bui lt-in mcu or running on an exte rnal master control processor. this frees up mcu processing pow er to run and manage algorithms or transfer func tions of very high complexity to optimize fan speeds to achieve system cooling requirements. the psoc thermal management expansion board kit (tme ebk) is a part of the psoc development kit ecosystem and is designed to work with the cy8ckit-001 psoc development kit (dvk) and cy8ckit-030 psoc 3 deve lopment kit (dvk). it enables you to evaluate a system?s thermal management functions and capabilities of psoc 3 devices. you can evaluate the example projects described in this guide or design a nd customize your own thermal management solution using components in cypress?s psoc creator tm software (included in this kit) or by altering example projects provided with this kit. the psoc thermal management expansion board kit (tme ebk) is used with the psoc family of devices and is specifically designed and packaged fo r use with the psoc 3 device family. psoc 3 is a programmable system-on-chip platform that combines precision analog and digital logic with a high performance, single-cycle, 67mhz 8051 pro cessor. with the flexibility of the psoc architecture, you can easily create your own custom thermal mana gement solution on chip with the exact functionality you need, in th e way you want it?no more, no less. 3

chapter 2 tme ebk architecture this chapter provides information about the ar chitecture and block diagram of the tme ebk. 7 2.1 2 . 1 layout and components l a y o u t a n d c o mp o n e n ts the picture of the tme ebk is shown in figure 2-1 and figure 2-2 . they depict the layout of the board and indicate the lo cations of the connectors and key components. figure 2-1 tme pcb (top)
figure 2-2 tme pcb (bottom) 8 2.2 2 . 2 thermal management solution on the tme t h e r ma l ma n a g e me n t s o l u ti o n o n th e t me the tme ebk contains two 4-wire, 12v brushl ess dc fans with connectors to support an additional 2 fans for designers who need to prototyp e with their own specific fan models. 6 temperature sensors (4 different kinds) are also installed on the kit: 1) tmp175 i2c digital temperature sensor, 2) 2x tmp05 pwm output di gital temperature sensors, 3) ds18s20 ?one wire? digital temperature sensor and 4) 2x mm bt3094 temperature diodes. this combination of hardware elements enables designers to rapidl y prototype thermal management solutions in a variety of configurations. tme ebk also provides an i2c/smbus/pmbus comp atible header to support systems that have a requirement for communication with a host controller. all of this f unctionality is implemented on a single psoc 3. the tme routes all the input/output signals for th ermal management to a psoc 3 mounted on a development kit platform such as the cy8ckit-001 psoc development kit or cy8ckit-030 psoc 3 development kit. psoc 3 is not mounted on the tme ebk itself. figure 2-3 shows a functional diagram of the psoc th ermal management solution. this solution enables control of up to 4x 4-wire fans using mcu based firmware control or hardware control. fan drive signals are generated by inde pendent hardware pwm blocks in psoc to drive the 4 wire fans. tachometer signals from the fans are interprete d by psoc to determine fa n rotational speeds. in hardware control mode, speed control is implem ented entirely in hardware (no mcu intervention required). in firmware control mode, speed cont rol can be achieved by the firmware running on psoc with cpu intervention. in both cases, fan stall or rotor lock faults are detected by hardware.
to support digital sensor temperat ure sensing, standard psoc inte rfaces are used where possible (such as i2c) and custom psoc components have been developed for non- typical digital sensors such as the pwm output tmp05 sensor. this is explained in section 4 of this user?s manual. for analog sensors, psoc also provid es on-board filtering, multiplexing and a 0.1% accurate internal voltage reference for high resolution and highly accurate temper ature sensor measurement. one of the example projects prov ided with the tme ebk shows an example of how to aggregate temperature sensor readings using a variety of methods and the resu ltant ?zone? temperature used to set individual fan speeds ? this is referred to as defining a ?thermal zone?. the example project shows how each fan can be configured independen tly to be dependent on any of the available temperature sensors in any combination. it also gives some examples of how the composite ?zone temperature? can be used to determine the required fan speed to achieve system cooling needs. although not included in the example projects pr ovided, psoc 3 devices also include non-volatile eeprom memory that can be used to store sensor calibration information or for event/fault logging purposes. communication with a host controller or management proc essor can be achieved via i2c, smbus, pmbus or a variety of other communicat ions protocols implemented with easy-to-use psoc creator component blocks. (x4) (x4) pwm (x4) ebk supports 4 fans (2 installed) figure 2-3 thermal management functional block diagram note that tme ebk hardware limits support to a maximum of 4 fans. the psoc 3 thermal management solution can be easily extended to s upport up to 16 fans or more in a single device. contact cypress for further information on the full psoc thermal management solution. 9

(751 th/tl). the tmp05 sensors have a 2 pin interface: 1) c onv/in input that when pulsed by psoc initiates a new temperature measurement, 2) out output th at provides a pwm signal that can be decoded using the formula above to determine ambient temperature. the tmp05 sensors support a daisy
chain mode of operation where the out signal of the first sensor can be dire ctly connected to the conv/in input of the subsequent sensor. the out of the 2 nd sensor carries the pwm signals from both sensors. many sensors can be daisy chained in this fashion, with the final out signal carrying the pwm temperature encodings from all sensors in the daisy chain. this sensor is generally operated in one of two modes: (1) one-shot mode and (2) continuous mode. for more detailed information, plea se refer to the tmp05 device data sheet which is available on the device manufacturer?s website or under the datasheet folder of the kit cd. figure 3-2 shows the tmp05 digital temperature sensor interface custom component instantiated in a psoc creator schematic configur ed to support the 2 tmp05 sensors on the tme in daisy chain mode. a single tmp05 digital temperature sensor interface component supports up to 4x tmp05 sensors in a sing le daisy chain. p_in and p_out are the tmp05 sensor signals available on the 2x20 pin header on tme ebk. figure 3-2 tmp05 temperat ure sensor connectivity the tmp05 digital temperature sensor interface component is currently under development and is not provided in this release of the tme ebk. check the tme ebk link: www.cypress.com/go/CY8CKIT-036 for upgrades to the tme that might include this component in the future. 13 3.4 3 . 4 i2c digital temperature sensor i 2 c d i g i ta l t e mp e r a tu r e s e n s o r the psoc tme ebk demonstrates i2c temperature sensing capability using a two-wire i2c compatible digital temperature sensor, the tm p175. i2c digital temperature sensors are very common sensors for thermal management and are used in a variety of communication, computer, consumer, environmental, industrial and instrument ation applications due to the popularity of the i2c bus. for more detailed information, please refer to its datasheet which is available on manufacturer?s website or under the datasheet folder of the kit cd. figure 3-3 shows the standard psoc creator i2c master component instantiate d in a psoc creator schematic connected to the tmp175 sensor on th e tme ebk. t_sda and t_scl represent serial data and serial clock respectively which are available on the 2x20 pin header on tme ebk.

figure 4-11 cy8ckit-030 psoc 3 dvk wi th tme ebk connected to port e (running example 3) ? example1: firmware based fan control overview the purpose of this example is to demonstrate the fan controller component controlling the two fans on the tme ebk in firmware (cpu) control mode. it is called open loop to describe the fact the hardware components used in this implem entation are not regula ting the fan speeds by themselves. instead, psoc firmware is enti rely responsible for managing fan speeds. if the project is running correc tly, the text displayed on the de bug lcd should display something like figure 4-12 : figure 4-12 example1 lcd display 24
the fans spin up to an initial speed target, or desired speed, of 5000 revol utions per minute (rpm) set by a #define in main.c . the desired speed is shown in the top left corner of the lcd display. the user can adjust the desire d speed up or down in steps of 500 rpm by pressing buttons on the dvk as follows: cy8ckit-001 psoc dvk: sw1=decrease speed, sw2=increase speed cy8ckit-030 psoc 3 dvk: sw2=decreas e speed, sw3=increase speed a firmware algorithm responds to changes in desire d speed by adjusting the duty cycle for both fans and continuously works at fine tuning the duty cy cle until the actual fan speeds approach the desired speed. the center section of the lcd display shows the actual speed in rpms of both fans. the right side of the lcd display shows the duty cy cles of each fan for reference. note that the duty cycles may not be the same for both fans, ev en though the desired speed is the same. this is due to variations in the actual electr omechanical performance of the 2 fans. the ?f/w? text displayed on the bottom left of th e display highlights that this project is using firmware speed control. this is done because the lcd display in example project 2 (when hardware closed loop control is intr oduced) is virtually identical, so this text helps to identify which example project is currently running on psoc. technical details the fan control portion of the example 1 top level schematic is shown in figure 4-13 figure 4-13 example1 project schematic 25
the fan controller component can be configured by d ouble-clicking on it in the top level schematic for example 1. this will open the customizer basic tab . for this example, ensure that the control mode is set to firmware (cpu) . other options are not important for this example. (see figure 4-14 ) figure 4-14 example1 fan contro ller customizer ? basic tab click on the fans tab to setup the electromechanical properties of the fans installed on the tme ebk. the rpm a, duty a (%) and the rpm b, duty b (%) parameters represent two data points from the fan?s pwm duty cycle to speed conversi on chart. that informa tion can be obtained from the fan manufacturer?s datasheet. the parameters shown below match the fa ns installed on the tme ebk. (see figure 4-15 ) 26
figure 4-15 example1 fan controller customizer ? fans tab firmware is able to control the fans using these provided fan controller component apis: fancontroller_start() fancontroller_getactualspeed(fannumber) fancontroller_setdutycycle(fannumber, dutycycle) the time taken to measure the actual speeds of each fan is relatively long, particularly for slow rotational speeds. for example, a fan running at 1000 rpm equates to a 60 ms rotation time. the mcu core inside psoc is capable of running at clock speeds as high as 67mhz. since the speed measurement hardware needs to run so much more slowly than the firmware can, some method of alerting the firmware that a new fan speed measurem ent is available is desirable. this enables the mcu to perform other tasks while waiting for new fan speed data to become available. this synchronization mechanism is achieved using the eoc signal on the fan controller component and the eocstatus status register (both are shown in the schematic in figure 4-13 ). every time the fan controller component completes a new speed measurement for both fans, it pulses the eoc signal high momentarily which is la tched by the status register. in example1, the main code loop polls for a ?1? in the eocstatus register and only then runs its basic speed adjustment algorithm. the speed adjustme nt algorithm detects if the current fan speed is too fast or too slow (within a user defined thre shold). if the speed is outside the threshold, the 27
algorithm adjusts the pwm duty-cycl e (up or down) by either a large or small value depending on how far out of range the current speed is. examine the main code loop in main.c for details. note: that the eoc signal in this project is also routed to a gpio (p0.0) so that it can be observed on a scope or logic analyzer. firmware flowchart the firmware flowchart for the example1 project is shown below (see figure 4-16) figure 4-16 example1 firmware flowchart 28
? example2: closed loop hardware fan control overview the purpose of this example is to demonstrate the fan controller component controlling the two fans on the tme ebk in hardware (udb) control mode. it is called closed loop to describe the fact the hardware components used in this implementation are working together to regulate the fan speeds by themselves. psoc firmware plays no part in managing the fan speeds in this configuration. if the project is running corre ctly, the text displayed on the debug lcd should display something like figure 4-17 figure 4-17 example2 lcd display the user interface for this exam ple is identical to example1. use the 2 switches on your dvk to adjust desired fan speeds up or down. in exam ple2, a hardware control algorithm responds to changes in desired speed by adjusting the duty cycl e for both fans and continuously works at fine tuning the duty cycle until the actual fan speeds approach the desired speed. the ?h/w? text displayed on the bottom left of the display highli ghts that this project is using hardware speed control. additionally, this example demonstrates the fault detection and alert signaling capabilities of the fan controller component. fault detection and alert signaling are handled in hardware. the fan controller is capable of signaling two types of alerts: fan stall/rotor lock: occurs when the com ponent detects that a fan has stopped spinning speed failure: occurs when a fan is unable to reach the desired speed all alerts are routed to a common alert pin on the fan controller component. the provided component application programmer in terfaces (apis) allow firmware to determine the exact source of the fault. in this example, the alert pin is tied to an interrupt which clears the fault source and displays the fault state on the lcd screen. fan stall faults can be simulated by unplugging a fan which disconnects the tachometer connection back to psoc. speed failures can be simulated by setting the desired speed to a value that the fan is incapable of reaching. for example, setting the desired speed to 2000 rpm for the fans installed on tme ebk will generate a speed failure since those fans can run no slower than around 2000 rpm. in the event of an alert, the words ?stall? or ?speed? will replace the current actual sp eed reading on the lcd display for that fan. 29
technical details the fan control portion of the example 2 top level schematic is shown below in figure 4-18 figure 4-18 example2 schematic example2 implements a hardware controlle d, closed-loop fan controller using the fan controller component in hardware (udb) control mode. firmware does not control fan speeds but can still interact with the fan controller component using these provided apis: 1. fancontroller_start() 2. fancontroller_setdesiredspeed(fannumber, rpm) 3. fancontroller_getactualspeed(fannumber) unlike example1, where the firmware must cons tantly monitor the actual fan speeds and make pwm duty cycle adjustments, here psoc hardwa re blocks automatically adjust the pwm duty-cycles to maintain the desired speed. the fa ncontroller_getactualspeed() api is only used to report the current speed on the lcd display. like wise, fancontroller_setdesiredspeed() is only used to modify the target desired speed when the user requests a speed adjustment via the pushbutton switches. another featur e of example2 is the addition fan stall/rotor lock and udb speed regulation failure alerts. this project uses the follo wing fan controller apis for alert signal handling: 1. fancontroller_getalertsource() 2. fancontroller_getfanstallspeedstatus() 3. fancontroller_getfanstallstatus() 30
alerts are enabled via checkboxes on the fan controller component customizer shown below. to configure the fan controller component double-click on the fan controller component in the top level schematic for example2. (see figure 4-19 ) figure 4-19 example2 fan contro ller customizer ? basic tab once either of the alerts has been enabled, the fan controller will assert the alert pin (high) when the enabled condition occurs (and for as long as it persists) on any of the fans. in this example, the alert pin has been tied to a standard psoc creator interrupt component. the interrupt component allows the user to insert custom code to ha ndle the interrupt. the custom handler for the alert interrupt can be found in the file alertint.c and is shown below: cy_isr(alertint_interrupt) { /* place your interrupt code here. */ /*`#start alertint_interrupt` */ uint8 alertstatus; /* determine alert source: stall or sp eed regulation failure (could be both) */ alertstatus = fancontroller_getalertsource(); /* if stall alert, determine which fan(s) */ if (alertstatus & fancontroller_stall_alert) 31
32 stallstatus = fancontroller_getfanstallstatus(); /* if speed regulation failure alert, determine which fan(s) */ if (alertstatus & fancontroller_speed_alert) speedstatus = fancontroller_getfanspeedstatus(); /* `#end` */ } the interrupt handler first calls fancontroller_getalertsource() to determine the alert/fault type (stall or speed failure). it then calls fancontroller_getfanstallspeedstatus() or fancontroller_getfanstallstatus() to determine which fan(s) caused the alert. note that fancontroller_getfanstallspeedstatus() and fancontro ller_getfanstallstatus() both clear the alert pin when called. the interrupt handler then sets bits in the stallstatus and speedstatus global variables. the main code loop po lls these global variables to update the lcd display with the fan status. note that the alert signal in this project is also routed to a general purpose io (gpio) p0.0 so that it can be observed on a scope or logic analyzer. firmware flowchart the firmware flowchart for the exam ple2 project is shown below (see figure 4-20 ). in this example project, the firmware only needs to mainta in the user interface: handle switch presses and update the lcd. the fan controller component closed loop hardware control loop does the rest.

34 ? example3: thermal management system overview example 3 demonstrates how the temperature sens ors combined with the fans on the tme ebk can create a complete thermal management system. the example shows how to combine temperature readings from a number of te mperature sensors in a variety of ways and use the composite temperature to set desired fan speeds accord ing to a customizable transfer function. the thermal management example project uses the c oncept of a ?thermal zone?. in this context, a thermal zone describes 2 things: 1) how to combin e multiple temperature sensor readings together to form a composite ?zone temperature? and 2) how to map the zone temperature to a fan speed. therefore, by this definition, each fan will be co ntrolled according to it s own independent thermal zone. this example has two thermal zones si nce the tme ebk has only 2 fans installed. algorithms currently implemented to combine multip le temperature sensors into a composite zone temperature include: 1) straight average, 2) weighted average, 3) maximum. in this example project, the wei ghted method is used on both fans. a zone temperature to fan speed transfer function is then definable for each zone. transfer functions currently implemented include: 1) linear and 2) table driven. in this example proj ect, the transfer function used is table driven on both fans. that is, a look-up table maps co mposite zone temperature to fan speed. this example is a simulation of a thermal management system. the first zone, zone 1 , combines temperature measurements from two temperatur e sensors (1 analog and 1 digital). the analog sensor is simulated using a variable potentiometer to allow easy demonstration of fan control over a wide simulated temperature range without the need of an environmental chamber to cycle through temperatures. in zone 1 , the temperature sensors are combined using a weighted average where the potentiometer is given 90% wei ght and the digital i2c temp sensor (u1 on tme ebk) is given 10% weight. adjust the potenti ometer (r20 on the cy8ckit-001 psoc development kit and r56 on the cy8ckit-030 psoc 3 development kit) to va ry the simulated temperature value in the approximate range of 15 to 100 degrees c. the zone 1 speed transfer functi on is table driven and follows the profile shown in figure 4-21 .
figure 4-21 example3 - zone 1 thermal profile zone 2 consists of 2 temperature sensors and a single fan. the zone 2 speed transfer function is table driven and is shown below in figure 4-22 . note that the temperature range is very narrow and close to room temperature. this is to allow for s imple testing at room by ju st touching a temperature sensor with a warm finger to cause a fan speed change. in zone 2, the temperature sensors are combined using a weighted average where the dig ital i2c temperature sensor (u1 on tme ebk) is given approximately 99% of the we ight. and the potentiome ter is given 1% weight. in this example u1?s temperature reading will dominate th e overall zone temper ature calculation. figure 4-22 example 3 - zone 2 thermal profie in this example, the lcd screen displays stat us information about thermal management system across three screens. the user can cycle thro ugh the status screens by pressing sw1 on the 35
cy8ckit-001 psoc development kit or sw2 on the cy8ckit-030 psoc 3 development kit. the three screens are: screen 1 - zone 1 summary this screen displays the current status of zone 1 . line 1 displays the zone number, the current composite zone temperature and the zone temper ature calculation algorithm used. line 2 displays the desired fan speed and the actual fan speed for zone 1. figure 4-23 example3 ? zone 1 summary screen 2 - zone 2 summary this screen displays the current status of zone 2 . line 1 displays the zone number, the current composite zone temperature and the zone temper ature calculation algorithm used. line 2 displays the desired fan speed and the actual fan speed for zone 2. figure 4-24 example3 ? zone 2 summary screen 3 - temperature sensors summary this screen displays the current temperature sens or readings for all sensors in the system. line 1 displays the zone 1 temperature sensor values. the left most temperature is the zone?s composite temperature followed by the temperatures of each contributing se nsor. line 2 displays the same information for zone 2. figure 4-25 example3 ? temperature sensors summary technical details the thermal management system example consists of two parts: 1) the main application and 2) the thermal manager. the main application is respons ible for the user interf ace and for periodically 36
calling the thermal manager. the application implementation can be found in main.c and on the test application tab of the project?s schematic. the ther mal manager implementation can be found in thermalmanager.c and on the thermal manager tab of the project?s schematic. the main application only needs to call thermalm anager_start() to initialize the thermal manager and then it must periodically ca ll servicethermalmanager() to r un temperature and speed updates. in this example, this is done every 500ms but can be changed by modifying #define thermal_update_ms_rate in main.c . all the parameters that define the zone compos ite temperature sensor algorithm and the zone temperature to fan speed algorithm are defined at the top of thermalmanager.c. to modify these settings, refer to thermalmanager.h for the relevant keywords. firmware flowchart the following flowchart shows the basic function of the thermal ma nager along with the apis in thermalmanager.c that implement the main service loop: figure 4-26 thermal manager flowchart 37
