detailed description the max32600 microcontroller is based on the industry- standard arm cortex-m3 32-bit risc cpu and includes 256kb of lash memory, 32kb of sram, and a 2kb 2-way set associative cache. the device includes three spi master interfaces, two uarts, two i 2 c master interfaces and one i 2 c slave interface, four 32-bit timers (each of which can be optionally split into dual 16-bit timers), a real-time clock (rtc) with three programmable alarms, dual independent windowed watchdog timers, and four supply voltage monitors with multiple user-selectable, low-voltage detection levels. for system security and integrity checking, a trust protection unit (tpu) is optionally available that includes all necessary features to secure communications and protect internal data and irmware. integrated high-performance analog peripherals include a 16-bit adc with input buffer, programmable gain ampliier, and a dual 8:1 differential (or 16:1 single- ended) input mux, two 12-bit dacs, two 8-bit dacs, four operational ampliiers with comparator mode, four low- power comparators, an internal temperature sensor, a high-precision internal programmable reference, and four spst analog switches. a multichannel pmu (peripheral management unit) interface, with operation during run mode and low-power sleep mode, can be used to conigure and transfer data to and from peripherals including the adc, dacs, communications ports, usb, tpu, and the crc hardware module. arm cortex-m3 core the device is based on the arm cortex m3 32-bit risc cpu, which implements the armv7-m architectural proile. the implementation of the cortex m3 core used in the device is targeted for a maximum operating frequency of 24mhz and provides the following features: 32-bit data path with mixed 16-bit and 32-bit instruc- tions (thumb ? -2 instruction set) single-cycle multiplication and hardware-based divi- sion operations nested vectored interrupt controller (nvic) with multiple interrupt priority levels and nested interrupt support 32-bit byte address data pointers for a maximum addressable 4gb memory space, shared by code memory, data memory, arm core peripherals and device-speciic peripherals low-power, highly energy eficient core reduces power consumption built-in debug functionality with jtag port (connects to internal debug access port) power-saving sleep and deep sleep modes with fast wake-up interrupt sources the devices include the arm nested vector interrupt controller (nvic) providing high-speed, deterministic response, interrupt masking, and multiple interrupt sources. each peripheral is connected to the nvic and can have multiple interrupt lags indicating the speciic source of the interrupt within the peripheral. the device supports up to 64 distinct interrupt sources (including internal and external interrupts), with eight priority levels. low power modes the max32600 has multiple operating modes with many user-conigurable options offering signiicant lexibility in total power consumption. these options are stored in the data retention power domain registers and are continuously powered across all modes of operation. the registers dictate which analog and digital peripherals are intended to remain enabled during low power modes. likewise, there are dedicated system registers that dictate the coniguration of features during run modes. the max32600 supports four power modes: lp0: stop, lp1: standby, lp2: pmu,and lp3: run. the low power modes (lp0: stop and lp1: standby) are under the control of the power sequencer, while lp2: pmu is controlled by the pmu, and the lp3: run mode is controlled by the arm core. the vrtc power pin (powered by battery or super cap) ensures that this domain is always on during battery change or other loss-of-power events on the main supply. thumb is a registered trademark of arm ltd. max32600 wellness measurement microcontroller www.maximintegrated.com maxim integrated 29 downloaded from: http:///
pmu the device's peripheral management unit (pmu) is a dma-based linked list processing engine. the pmu can perform operations and data transfers involving memory and/or peripherals in the advanced peripheral bus (apb) and advanced high-performance bus (ahb) peripheral memory space while the main cpu is in a sleep state. this allows low-overhead peripheral operations (for which intensive cpu resources are not required) to be performed without the cpu, signiicantly reducing overall power consumption. additionally, for certain analog and digital operations, switching the cpu off and handling the operations using the pmu provides a lower-noise environment that is critical for obtaining optimum analog- to-digital converter (adc) and digital-to-analog converter (dac) performance. crc module a crc hardware module is included to provide fast calculations and data integrity checks by application software. the crc module supports both the crc-16- ccitt and crc-32 polynomials. the crc-16 and crc- 32 calculation engines operate independently in parallel; each crc engine has a programmable start seed and can be used to calculate checksums of arbitrarily long data sequences. data can be loaded either directly or using the pmu; the crc-16-ccitt completes in two clock cycles and the crc-32 completes in four clock cycles for each data input calculated. watchdog timers the device provides two independent watchdog timers (wdt) with window support. the watchdog timers are independent and have multiple clock source options to ensure system security. the watchdog uses a 32-bit timer with prescaler to generate the watchdog reset. when enabled, the watchdog timers must be fed prior to timeout or within a window of time if window mode is enabled. failure to feed the watchdog timer during the programmed timing window results in a watchdog timeout. 32-bit/16-bit timers the device includes four 32-bit timers that are usable for timing, capture/compare, or generation of pulse- width modulated (pwm) signals. each 32-bit timer can optionally be split into a pair of 16-bit timers. the capture/ compare, input/output, and pwm options are available on the 32-bit timers only. features of the 32-bit timers include the following: 32-bit counter with one-shot and continuous auto-reload modes programmable prescaler for timer input clock external i/o pin option allows selectable input or out- put function for each timer instance using gpio pin output mode can be used for pwm output genera- tion or timer rollover output input mode can be used for timer input (counter mode), clock gating or capture, limited to an input frequency of one-fourth the peripheral clock fre- quency timer interrupt real-time clock a binary real-time clock (rtc) keeps the time of day in a 32-bit timer with resolution programmable from 244s to 1 second. with a 1-second tick frequency, the rtc can count up to 139 years before rolling over. two time-of- day alarms can be used to trigger an interrupt or wake up the devices from low-power mode when the rtc timer reaches a speciied value; a separate sub-second alarm can be set to trigger on a programmable subdivide of the rtc tick period. for example, with a 1-second rtc resolution, the sub-second alarm can be triggered every second, every 500ms, every 250ms, every 125ms, and so on down to a minimum of 244s. usb device controller the integrated usb controller is compliant with the usb 2.0 speciication, providing full-speed operation as a usb peripheral device. integrating the usb physical interface (phy) allows direct connection to the usb cable, reducing board space and overall system cost. an integrated voltage regulator enables smart switching between the main supply and v bus when connected to a usb host controller. the usb controller includes a dedicated dma engine (separate from the pmu) that is used to transfer data to and from the endpoint buffers located in sram. a total of seven endpoint buffers are supported with conigurable selection of in or out, in addition to endpoint 0, which is used for control purposes only. i 2 c master/slave interfaces two i 2 c master interfaces and one i 2 c slave interface are available for communication with a wide variety of other i 2 c-enabled peripherals. the i 2 c bus is a 2-wire, bi- directional bus using a ground line and two bus lines, the serial data line (sda) and the serial clock line (scl). both the sda and scl lines must be driven as open-collector/ drain outputs. external resistors (r p ) are required pull the lines to a logic-high state. max32600 wellness measurement microcontroller www.maximintegrated.com maxim integrated 30 downloaded from: http:///
the device supports both the master and slave protocols. in the master mode, the interfaces have ownership of the i 2 c bus, drive the clock, and generate the start and stop signals. this allows them to send data to a slave or receive data from a slave as required. in slave mode, the interfaces rely on an externally generated clock to drive scl and respond to data and commands only when requested by the i 2 c master device. spi master interfacesthe device has three spi master interface ports. each spi controller provides an independent master-mode serial communication channel that communicates synchronously with peripheral spi devices in a single or multiple slave system. the third spi instance is intended for future bluetooth module communication. the spi controllers support half- or full-duplex communications with single, dual, or quad data transmission modes, and can be operated in master mode only. multiple slave select lines are available with conigurable polarity, and optional slave ready (sr) inputs can be used for hardware low control for spi devices that support this function. uart interfaces the device has two serial communication interfaces. the universal asynchronous receiver-transmitter (uart) interface ports support full-duplex asynchronous communications. the two uarts implemented on the devices are identical in behavior and can be conigured independently. uart features include the following: 2-wire interface programmable transmit and receive interrupts independent baud-rate generators programmable even/odd/no parity modes programmable start/stop bit options character lengths of 5/6/7/8 bits supported optional hardware low control (rts/cts) lcd controller the 192-ball max32600 include an lcd controller with a boost regulator that interfaces directly to common low- voltage liquid crystal displays. by integrating the lcd controller in hardware, the device allows designs that require only an lcd glass rather than a considerably more expensive lcd module. every character in an lcd glass is composed of one or more segments, each of which is activated by selecting the appropriate segment and common signal. the lcd controller can multiplex combinations of up to 40 segment outputs (seg0 to seg39) and four common signal outputs (com0 to com3). unused segment outputs can be used as standard gpio port pins. the segments are easily addressed by writing to dedicated display memory. once the lcd controller settings and display memory have been initialized, the 21-byte display memory is periodically scanned, and the segment and common signals are generated automatically at the selected display frequency, with no additional cpu intervention required. the design is further simpliied and cost reduced by the inclusion of software-adjustable internal voltage-dividers to control display contrast, using either v ddio or an external voltage. if desired, contrast can also be controlled with an external resistor network. features of the lcd controller include the following: automatic lcd segment and common-drive signal generation integrated boost regulator ensures lcd operation over entire digital operating range flexible lcd clock source selection with adjustable frame frequency internal voltage-divider resistors eliminate require- ment for external components internal adjustable resistor allows contrast adjust- ment without external components four display modes are supported by the lcd controller: static (com0) 1/2 duty multiplexed with 1/2 bias voltages (com[0:1]) 1/3 duty multiplexed with 1/3 bias voltages (com[0:2]) 1/4 duty multiplexed with 1/3 bias voltages (com[0:3]) the voltages available for driving the lcd are v lcd , v lcd 2/3, v lcd 1/3, and v adj . the 1/2-bias mode, which uses an output level of v lcd 1/2, requires two of the lcd voltage supply pins (v lcd2 and v lcd1 ) to be shunted together externally. max32600 wellness measurement microcontroller www.maximintegrated.com maxim integrated 31 downloaded from: http:///
16-bit adc with pga the devices include a 16-bit analog-to-digital converter (adc) with a 16-channel analog input multiplexer, to allow selection of an analog input from one of 16 input lines (single-ended mode) or one pair of eight input pairs (differential mode). the differential mode supports fully differential signal inputs. the front end pga allows programmable gain settings of x1, x2, x4, and x8 before the input sample is converted. an anti-aliasing ilter is included between the output of the pga and the adc sample conversion stage. the adc reference voltage is selectable between v dda3 and the dedicated adc reference level. the adc reference level can be set by software to one of four output levels1.024v, 1.5v, 2.048v, and 2.5vbased on the 1.24v reference bandgap. adc/dac internal/external reference and programmable output buffers two programmable reference levels (one used by the adc, one used by the dacs) are included, and each can be individually set to one of four output levels. an external reference can also be provided at the refadj pin; if this feature is used, the external reference voltage is used in place of the 1.24v bandgap output, and the programmable output levels for the adc and dac references shift accordingly. 12-bit voltage output dacs the device includes two 12-bit voltage output dacs that output single-ended voltages. the reference used by these dacs is selectable between the dac reference level and the adc reference level. each dac instance includes pmu channel access to allow output values to be loaded to the dac directly from memory. 8-bit voltage output dacs the device includes two 8-bit voltage output dacs that output single-ended voltages. the reference used by these dacs is selectable between the dac reference level and the adc reference level. each dac instance includes pmu channel access to allow output values to be loaded to the dac directly from memory. uncommitted op amps with comparator mode the device contains four uncommitted operational ampliiers. any unused op amp should be connected with its positive input pin grounded and the negative input pin and output pin shorted together. each op amp can be switched between ampliier and comparator mode under software control. each op amp contains an integrated internal switch that can be used to short the negative/inverting input pin to the output pin of the op amp under software control, putting the op amp in a voltage follower mode. in this coniguration, the op amp can be used as an output buffer for any of the four dac outputs. any of the four dac outputs may optionally be internally connected to the noninverting inputs of one or more of the four op amps, under software control. uncommitted spst analog switches the device contains four uncommitted spst analog switches that can be opened and closed under software control. all spst switches are open by default following any reset or power-on reset. the spst switches support input voltages from ground to v dda3 . temperature sensor the device includes an internal temperature sensor that can be read using the adc, and additionally supports a mode for an external temperature sensor, which is connected to the same adc input pair. max32600 wellness measurement microcontroller www.maximintegrated.com maxim integrated 32 downloaded from: http:///
