USB Transceiver Regulator 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. 1.5K 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 GPIO are also included. System resources provide additional capability, such as a configurable I2C 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. Document Number: 001-12394 Rev. *S DP TD DM TRANSMITTER PDN RD DPO RSE0 The enCoRe V Core During USB operation, the CPU speed can be set to any setting. Be aware that USB throughput decreases with a decrease in CPU speed. For maximum throughput, the CPU clock should be made equal to the system clock. The system clock must be 24 MHz for USB operation. 5K TEN RECEIVERS 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, I2C hardware address recognition, new very low current sleep mode, and new package options. 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 and ILO. 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. PS2 Pull Up VOLTAGE REGULATOR 5V 3.3V DMO 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 unidirectional data endpoints are individually configurable as either IN or OUT. Low value series resistors REXT (22 Ω) must be added externally to the D+ and D– lines to meet the driving impedance requirement for full-speed USB. 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 cyclical redundancy checks (CRCs). Incoming packets failing checksum verification are ignored. ■ Checks addresses. Ignores all transactions not addressed to the device. ■ Sends appropriate ACK/NAK/Stall handshakes. ■ Identifies token type (SETUP, IN, OUT) and sets the appropriate token bit once a valid token in received. ■ Identifies Start-of-Frame (SOF) and saves the frame count. ■ Sends data to or retrieves data from the USB SRAM, by way of the PSoC Memory Arbiter (PMA). Page 3 of 41 CY7C6431x CY7C6434x CY7C6435x Firmware is 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. input mux or the temperature sensor with an input voltage range of 0 V to VREFADC. In the ADC only configuration (the ADC MUX selects the Analog mux bus, not the default temperature 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. 10-bit ADC SPI 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 the 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. The serial peripheral interconnect (SPI) 3-wire protocol uses both edges of the clock to enable synchronous communication without the need for stringent setup and hold requirements. Figure 2.

SCLK MOSI MISO TEMP DIODES ADC SYSTEM BUS INTERFACE BLOCK COMMAND/ STATUS 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 essentially 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 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. I2C Slave The I2C slave enhanced communications block is a serial-to-parallel processor, designed to interface the enCoRe V device to a two-wire I2C serial communications bus. To eliminate the need for excessive CPU intervention and overhead, the block provides I2C-specific support for status detection and generation of framing bits. By default, the I2C slave enhanced module is firmware compatible with the previous generation of I2C slave functionality. However, this module provides new features that are configurable to implement significant flexibility for both internal and external interfacing. The basic I2C features include: ■ Slave, transmitter, and receiver operation. ■ Byte processing for low CPU overhead. ■ Interrupt or polling CPU interface. ■ Support for clock rates of up to 400 kHz. ■ 7- or 10-bit addressing (through firmware support). ■ SMBus operation (through firmware support). Enhanced features of the I2C 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 I2C block controls the data (SDA) and the clock (SCL) to the external I2C interface through direct connections to two dedicated GPIO pins. When I2C 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 I2C slave modules, the I2C 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 I2C bus continues. However, this I2C Slave Enhanced module provides new data buffering capability as an enhanced feature. In the EZI2C buffering mode, the I2C slave interface appears as a 32-byte RAM buffer to the external I2C master. Using a simple predefined protocol, the master controls the read and write pointers into the RAM. When this method is enabled, the slave never stalls the bus. In this protocol, the data available in the RAM (this is managed by the CPU) is valid. Figure 5.

PSoC Designer software accelerates system design and time to market. Develop your applications using a library of precharacterized analog and digital peripherals (called user modules) in a drag-and-drop design environment. Then, customize your design by leveraging the dynamically generated application programming interface (API) libraries of code. Finally, debug and test your designs with the integrated debug environment, including in-circuit emulation and standard software debug features. PSoC Designer includes: Code Generation Tools The code generation tools work seamlessly within the PSoC Designer interface and have been tested with a full range of debugging tools. You can develop your design in C, assembly, or a combination of the two. Assemblers. The assemblers allow you to merge assembly code seamlessly with C code. Link libraries automatically use absolute addressing or are compiled in relative mode, and linked with other software modules to get absolute addressing. ■ Application editor graphical user interface (GUI) for device and user module configuration and dynamic reconfiguration ■ Extensive user module catalog C Language Compilers. C language compilers are available that support the PSoC family of devices. The products allow you to create complete C programs for the PSoC family devices. The optimizing C compilers provide all of the features of C, tailored to the PSoC architecture. They come complete with embedded libraries providing port and bus operations, standard keypad and display support, and extended math functionality. ■ Integrated source-code editor (C and assembly) Debugger ■ Free C compiler with no size restrictions or time limits ■ Built-in debugger ■ In-circuit emulation PSoC Designer has a debug environment that provides hardware in-circuit emulation, allowing you to test the program in a physical system while providing an internal view of the PSoC device. Debugger commands allow you to read and program and read and write data memory, and read and write I/O registers. You can read and write CPU registers, set and clear breakpoints, and provide program run, halt, and step control. The debugger also allows you to create a trace buffer of registers and memory locations of interest. Built-in support for communication interfaces: 2 ❐ Hardware and software I C slaves and masters ❐ Full-speed USB 2.0 ❐ Up to four full-duplex universal asynchronous receiver/transmitters (UARTs), SPI master and slave, and wireless PSoC Designer supports the entire library of PSoC 1 devices and runs on Windows XP, Windows Vista, and Windows 7. ■ PSoC Designer Software Subsystems Design Entry In the chip-level view, choose a base device to work with. Then select different onboard analog and digital components that use the PSoC blocks, which are called user modules. Examples of user modules are analog-to-digital converters (ADCs), digital-to-analog converters (DACs), amplifiers, and filters. Configure the user modules for your chosen application and connect them to each other and to the proper pins. Then generate your project. This prepopulates your project with APIs and libraries that you can use to program your application. The tool also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic reconfiguration makes it possible to change configurations at run time. In essence, this allows you to use more than 100 percent of PSoC’s resources for a given application. Document Number: 001-12394 Rev. *S Online Help System The online help system displays online, context-sensitive help. Designed for procedural and quick reference, each functional subsystem has its own context-sensitive help. This system also provides tutorials and links to FAQs and an Online Support Forum to aid the designer. In-Circuit Emulator A low-cost, high-functionality In-Circuit Emulator (ICE) is available for development support. This hardware can program single devices. The emulator consists of a base unit that connects to the PC using a USB port. The base unit is universal and operates with all PSoC devices. Emulation pods for each device family are available separately. The emulation pod takes the place of the PSoC device in the target board and performs full-speed (24-MHz) operation. Page 7 of 41 CY7C6431x CY7C6434x CY7C6435x Designing with PSoC Designer The development process for the PSoC device differs from that of a traditional fixed-function microprocessor. The configurable analog and digital hardware blocks give the PSoC architecture a unique flexibility that pays dividends in managing specification change during development and lowering inventory costs. These configurable resources, called PSoC blocks, have the ability to implement a wide variety of user-selectable functions. The PSoC development process is: 1. Select user modules. 2. Configure user modules. 3. Organize and connect. 4. Generate, verify, and debug. Select User Modules PSoC Designer provides a library of prebuilt, pretested hardware peripheral components called user modules. User modules make selecting and implementing peripheral devices, both analog and digital, simple. Configure User Modules Each user module that you select establishes the basic register settings that implement the selected function. They also provide parameters and properties that allow you to tailor their precise configuration to your particular application. For example, a Pulse width modulator (PWM) user module configures one or more digital PSoC blocks, one for each eight bits of resolution. Using these parameters, you can establish the pulse width and duty cycle. Configure the parameters and properties to correspond to your chosen application. Enter values directly or by selecting values from drop-down menus. All of the user modules are documented in datasheets that may be viewed directly in PSoC Designer or on the Cypress website. These user module Document Number: 001-12394 Rev. *S data sheets explain the internal operation of the user module and provide performance specifications. Each datasheet describes the use of each user module parameter, and other information that you may need to successfully implement your design. Organize and Connect Build signal chains at the chip level by interconnecting user modules to each other and the I/O pins. Perform the selection, configuration, and routing so that you have complete control over all on-chip resources. Generate, Verify, and Debug When you are ready to test the hardware configuration or move on to developing code for the project, perform the “Generate Configuration Files” step. This causes PSoC Designer to generate source code that automatically configures the device to your specification and provides the software for the system. The generated code provides APIs with high-level functions to control and respond to hardware events at run time, and interrupt service routines that you can adapt as needed. A complete code development environment allows you to develop and customize your applications in C, assembly language, or both. The last step in the development process takes place inside PSoC Designer’s Debugger (accessed by clicking the Connect icon). PSoC Designer downloads the HEX image to the ICE where it runs at full speed. PSoC Designer debugging capabilities rival those of systems costing many times more. In addition to traditional single-step, run-to-breakpoint, and watch-variable features, the debug interface provides a large trace buffer. It allows you to define complex breakpoint events that include monitoring address and data bus values, memory locations, and external signals.

It lists all the registers in mapping tables, in address order. Register Conventions Register Mapping Tables The register conventions specific to this section are listed in the following table. The enCoRe V device has a total register address space of 512 bytes. The register space is also referred to as I/O space and is broken into two parts: Bank 0 (user space) and Bank 1 (configuration space). The XIO bit in the Flag register (CPU_F) determines which bank the user is currently in. When the XIO bit is set, the user is said to be in the “extended” address space or the “configuration” registers. Table 1.

When VDD remains in the range from 1.71 V to 1.9 V for more than 50 µsec, the slew rate when moving from the 1.71 V to 1.9 V range to greater than 2 V must be slower than 1 V/500 µsec to avoid triggering POR. The only other restriction on slew rates for any other voltage range or transition is the SRPOWER_UP parameter. 8. Errata: For Port 1 pins P1, P1, and P1 300 Ohm external resistor is needed to meet this spec. Refer to “Errata” on page 35 for more details. 9. If powering down in standby sleep mode, to properly detect and recover from a VDD brown out condition any of the following actions must be taken: • Bring the device out of sleep before powering down. • Assure that VDD falls below 100 mV before powering back up. • Set the No Buzz bit in the OSC_CR0 register to keep the voltage monitoring circuit powered during sleep. • Increase the buzz rate to assure that the falling edge of VDD is captured. The rate is configured through the PSSDC bits in the SLP_CFG register. For the referenced registers, refer to the enCoRe V Technical Reference Manual. In deep sleep mode, additional low power voltage monitoring circuitry allows VDD brown out conditions to be detected for edge rates slower than 1 V/ms.

Details include errata trigger conditions, scope of impact, available workaround, and silicon revision applicability. Contact your local Cypress Sales Representative if you have questions. CY7C643xx Errata Summary The following Errata item applies to the CY7C643xx data sheets. 1. Latch up susceptibility when maximum I/O sink current exceeded ■ PROBLEM DEFINITION P1, P1, and P1 pins are susceptible to latch up when the I/O sink current exceeds 25 mA per pin on these pins. ■ PARAMETERS AFFECTED LU – Latch up current. Per JESD78A, the maximum allowable latch up current per pin is 100 mA. Cypress internal specification is 200 mA latch up current limit. ■ TRIGGER CONDITIONS Latch up occurs when both the following conditions are met: A. The offending I/O is externally connected to a voltage higher than the I/O high state, causing a current to flow into the pin that exceeds 25 mA. B. A Port1 I/O (P1, P1, and P1 respectively) adjacent to the offending I/O is connected to a voltage lower than the I/O low state. This causes a signal that drops below Vss (signal undershoot) and a current greater than 200 mA to flow out of the pin. ■ SCOPE OF IMPACT The trigger conditions outlined in this item exceed the maximum ratings specified in the CY7C643xx data sheets. ■ WORKAROUND Add a series resistor > 300 to P1, P1, and P1 pins to restrict current to within latch up limits. ■ FIX STATUS This issue will be corrected in the next new silicon revision. 2. Does not meet USB 2.0 specification for D+ and D- rise/fall matching when supply voltage is under 3.3 V ■ PROBLEM DEFINITION Rising to falling rate matching of the USB D+ and D- lines has a corner case at lower supply voltages, such as those under 3.3 V. ■ PARAMETERS AFFECTED Rising to falling rate matching of the USB data lines. ■ TRIGGER CONDITION(S) Operating the VCC supply voltage at the low end of the chip’s specification (under 3.3 V) may cause a mismatch in the rising to falling rate. ■ SCOPE OF IMPACT This condition does not affect USB communications but could cause corner case issues with USB lines’ rise/fall matching specification. Signal integrity tests were run using the Cypress development kit and excellent eye was observed with supply voltage of 3.15 V. Document Number: 001-12394 Rev. *S Page 35 of 41 CY7C6431x CY7C6434x CY7C6435x Figure 21. Eye Diagram ■ ■ WORKAROUND Avoid the trigger condition by using lower tolerance voltage regulators.
