cy7c6431x cy7c6434x, cy7c6435x document number: 001-12394 rev *i page 2 of 32 functional overview the encore v family of devices are designed to replace multiple traditional full-speed usb microcontroller system components with one, low cost single-chip programmable component. communication peripherals (i2c /spi), a fast cpu, flash program memory, sram data memory, and configurable i/o are included in a range of convenient pinouts. the architecture for this device family, as illustrated in the ?encore v block diagram? on page 1, consists of two main areas: the cpu core and the system resources. depending on the encore v package, up to 36 general purpose i/o (gpio) are also included. this product is an enhanced version of cypress?s successful full speed-usb peripheral controllers. enhancements include faster cpu at lower voltage operation, lower current consumption, twice the ram and flash, hot-swappable i/os, i 2 c hardware address recognition, new very low current sleep mode, and new package options. the encore v core the encore v core is a powerful engine that supports a rich instruction set. it encompasses sram for data storage, an interrupt controller, sleep and watchdog timers, and imo (internal main oscillator) and ilo (internal low speed oscillator). the cpu core, called the m8c, is a powerful processor with speeds up to 24 mhz. the m8c is a four-mips, 8-bit harvard architecture microprocessor. system resources provide additional capability, such as a config- urable i 2 c slave and spi master-slave communication interface and various system resets supported by the m8c. full-speed usb the encore v usb system resource adheres to the usb 2.0 specification for full speed devices operating at 12 mb/second with one upstream port and one usb address. encore v usb consists of these components: serial interface engine (sie) block. psoc memory arbiter (pma) block. 512 bytes of dedicated sram. a full-speed usb transceiver with internal regulator and two dedicated usb pins. figure 1. usb transceiver regulator at the encore v system level, the full-speed usb system resource interfaces to the rest of the encore v by way of the m8c's register access instructions and to the outside world by way of the two usb pins. the sie supports nine endpoints including a bidirectional control endpoint (endpoint 0) and eight unidirectional data endpoints (endpoints 1 to 8). the unidirec- tional data endpoints are individually configurable as either in or out. the usb serial interface engine (sie) allows the encore v device to communicate with the usb host at full speed data rates (12 mb/s). the sie simplifies the interface to usb traffic by automatically handling the following usb processing tasks without firmware intervention: translates the encoded received data and formats the data to be transmitted on the bus. generates and checks crcs. incoming packets failing checksum verification are ignored. checks addresses. ignores all tr ansactions not addressed to the device. sends appropriate ack/nak/stall handshakes. identifies token type (setup, in, out) and sets the appro- priate token bit once a valid token in received. identifies start-of-frame (s of) and saves the frame count. sends data to or retrieves data from the usb sram, by way of the psoc memory arbiter (pma). voltage regulator 5v 3.3v

required to handle various parts of the usb interface. the sie issues interrupts after key usb events to direct firmware to appropriate tasks: fill and empty the usb data buffers in usb sram. enable pma channels appropriately. coordinate enumeration by decoding usb device requests. suspend and resume coordination. verify and select data toggle values. 10-bit adc the adc on encore v device is an independent block with a state machine interface to control accesses to the block. the adc is housed together with t he temperature sensor core and can be connected to this or the analog mux bus. as a default operation, the adc is connected to the temperature sensor diodes to give digital values of the temperature. figure 2. adc system pe rformance block diagram the adc user module contains an integrator block and one comparator with positive and negative input set by the muxes. the input to the integrator stage comes from the analog global input mux or the temperature s ensor with an input voltage range of 0v to 1.3 v, where 1.3v is 72 percent of full scale. in the adc only configuration (the adc mux selects the analog mux bus, not the default temp erature sensor connection), an external voltage can be connected to the input of the modulator for voltage conversion. the adc is run for a number of cycles set by the timer, depending upon the desired resolution of the adc. a counter counts the number of trips by the comparator, which is proportional to the input voltage. the temp sensor block clock speed is 36 mhz and is divided down to 1 to 12 mhz for adc operation. spi the serial peripheral interconn ect (spi) 3-wire protocol uses both edges of the clock to enable synchronous communication without the need for stringent setup and hold requirements. figure 3. basic spi configuration a device can be a master or slave. a master outputs clock and data to the slave device and inputs slave data. a slave device inputs clock and data from the master device and outputs data for input to the master. together , the master and slave are essen- tially a circular shift register, where the master generates the clocking and initiates data transfers. a basic data transfer occurs when the master sends eight bits of data, along with eight clocks. in any transfer, both master and slave transmit and receive simultaneously. if the master only sends data, the received data from the slave is ignored. if the master wishes to receive data from the slave, the master must send dummy bytes to generate the clocking for the slave to send data back. figure 4. spi block diagram

register (spi_cfg) sets master/slave functionality, clock speed, and interrupt select. spi control register (spi_cr) provides four control bits and four status bits for device interfacing and synchronization. the spim hardware has no support for driving the slave select (ss_) signal. the behavior and use of this signal is dependent on the application and encore v device and, if required, must be implemented in firmware. there is an additional data input in the spis, slave select (ss_), which is an active low signal. ss_ must be asserted to enable the spis to receive and transmit. ss_ has two high level functions: to allow for the selection of a given slave in a multi-slave environment. to provide additional clocking for tx data queuing in spi modes 0 and 1. i 2 c slave the i 2 c slave enhanced communications block is a serial-to-parallel processor, designed to interface the encore v device to a two-wire i 2 c serial communications bus. to eliminate the need for excessive cpu intervention and overhead, the block provides i 2 c-specific support for stat us detection and generation of framing bits. by default, the i2c slave enhanced module is firmware compatible with the previous generation of i 2 c slave functionality. however, this module provides new features that are configurable to implement significant flexibility for both internal and external interfacing. the basic i 2 c features include: slave, transmitter, and receiver operation. byte processing for low cpu overhead. interrupt or polling cpu interface. support for clock rate s of up to 400 khz. 7- or 10-bit addressing (through firmware support). smbus operation (through firmware support). enhanced features of the i 2 c slave enhanced module include: support for 7-bit hardware address compare. flexible data buffering schemes. a "no bus stalling" operating mode. a low power bus monitoring mode. the i 2 c block controls the data (sda) and the clock (scl) to the external i 2 c interface through direct connections to two dedicated gpio pins. when i 2 c is enabled, these gpio pins are not available for general purpose use. the encore v cpu firmware interacts with the block through i/o register reads and writes, and firmware synchronization is implemented through polling and/or interrupts. in the default operating mode, which is firmware compatible with previous versions of i 2 c slave modules, the i 2 c bus is stalled upon every received address or byte, and the cpu is required to read the data or supply data as required before the i 2 c bus continues. however, this i 2 c slave enhanced module provides new data buffering capability as an enhanced feature. in the ezi 2 c buffering mode, the i 2 c slave interface appears as a 32-byte ram buffer to the external i 2 c master. using a simple predefined protocol, t he master controls the read and write pointers into the ram. when this method is enabled, the slave never stalls the bus. in this pr otocol, the data available in the ram (this is managed by the cpu) is valid. figure 5. i 2 c block diagram i2c core i2c basic configuration i2c_cfg i2c_scr i2c_dr plus features hw addr cmp buffer module cpu port

additional ca pability useful to complete systems. additional resources include low voltage detection and power on reset. the following statements describe the merits of each system resource. low voltage detection (lvd) interrupts can signal the appli- cation of falling voltage levels, while the advanced por (power on reset) circuit eliminates t he need for a system supervisor. the 5v maximum
