Communication peripherals I2C/SPI , a fast CPU, Flash program memory, SRAM data memory, and configurable IO are included in a range of convenient pinouts. The architecture for this device family, as illustrated enCoRe V , is comprised of three main areas the CPU core, the system resources, and the full-speed USB system. Depending on the enCoRe V package, up to 36 general purpose IO GPIO are also included. This product is an enhanced version of Cypress’ successful full-speed USB peripheral controllers. Enhancements include faster CPU at lower voltage operation, lower current consumption, twice the RAM and Flash, hot-swapable IOs, I2C 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 configurable I2C slave/SPI master-slave communication interface and various system resets supported by the M8C. For up-to-date ordering, packaging, and electrical specification information, reference the latest enCoRe V device data sheets on the web at Development Kits Development Kits are available from the following distributors Digi-Key, Avnet, Arrow, and Future.

The PSoC Designer IDE and application runs on Windows NT Windows 2000, Windows Millennium Me , or Windows XP. Reference the PSoC Designer Functional Flow diagram below. PSoC Designer helps the customer to select an operating configuration for the USB, write application code that uses the USB, and debug the application. This system provides design database management by project, an integrated debugger with In-Circuit Emulator, in-system programming support, and the CYASM macro assembler for the CPUs. PSoC Designer also supports a high-level C language compiler developed specifically for the devices in the family. Figure PSoC Designer Subsystems PSoC Designer Software Subsystems Device Editor The device editor subsystem allows the user to select different onboard analog and digital components called user modules using the enCoRe V device blocks. Examples of user modules are timers, 10-bit ADC, SPI/I2C etc. The device editor also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic reconfiguration allows for changing configurations at run time. PSoC Designer sets up power-on initialization tables for selected enCoRe V block configurations and creates source code for an application framework. The framework contains software to operate the selected components and, if the project uses more than one operating configuration, contains routines to switch between different sets of enCoRe V block configurations at run time. PSoC Designer can print out a configuration sheet for a given project configuration for use during application programming in conjunction with the Device Data Sheet. Once the framework is generated, the user can add application-specific code to flesh out the framework. It is also possible to change the selected components and regenerate the framework. Application Editor In the Application Editor you can edit your C language and Assembly language source code. You can also assemble, compile, link, and build. Assembler. The macro assembler allows the merging of assembly code seamlessly with C code. The link libraries automatically use absolute addressing or are compiled in relative mode, and linked with other software modules to get absolute addressing. C Language Compiler. A C language compiler is available that supports the enCoRe V family of devices. Even if you have never worked in the C language before, the product quickly allows you to create complete C programs for the enCoRe V family devices. The embedded, optimizing C compiler provides all the features of C tailored to the enCoRe V architecture. It comes complete with embedded libraries providing port and bus operations, standard keypad and display support, and extended math functionality. Debugger The PSoC Designer Debugger subsystem provides hardware in-circuit emulation, allowing the designer to test the program in a physical system while providing an internal view of the PSoC device. Debugger commands allow the designer to read the program and read and write data memory, read and write IO registers, read and write CPU registers, set and clear breakpoints, and provide program run, halt, and step control. The debugger also allows the designer to create a trace buffer of registers and memory locations of interest. Online Help System The online help system displays online, context-sensitive help for the user. 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 getting started. Page 3 of 26 [+] Feedback CY7C6435x CY7C64345, CY7C6431x Hardware Tools In-Circuit Emulator A low cost, high functionality ICE In-Circuit Emulator is available for development support. This hardware has the capability to program single devices. The emulator consists of a base unit that connects to the PC by way of a USB port. The base unit is universal and operates with most Cypress USB and all PSoC devices. Emulation pods for each device family are available separately. The emulation pod takes the place of the enCoRe V device in the target board and performs full-speed 24 MHz operation. Designing with User Modules To speed the development process, the PSoC Designer Integrated Development Environment IDE provides a feature where the resources of the part are selected as user modules. For example, the timers, I2C, SPI resources are available as user modules. User modules make selecting and implementing peripheral devices simple and easy. Each user module establishes the basic register settings that implement the selected function. It also provides parameters that allow you to tailor its precise configuration to your particular application. User modules also provide tested software to cut your development time. The user module application programming interface API provides high-level functions to control and respond to hardware events at run time. The API also provides optional interrupt service routines that you can adapt as needed. The API functions are documented in user module data sheets that are viewed directly in the PSoC Designer IDE. These data sheets explain the internal operation of the user module and provide performance specifications. Each data sheet describes the use of each user module parameter and documents the setting of each register controlled by the user module. The development process starts when you open a new project and bring up the Device Editor, a graphical user interface GUI for configuring the hardware. You pick and place the user modules you need for your project. The tool automatically builds signal chains by connecting user modules to the default IO pins or as required. At this stage, you also configure the clock source connections and enter parameter values directly or by selecting values from drop-down menus. When you are ready to test the hardware configuration or move on to developing code for the project, you perform the “Generate Application” step. This causes PSoC Designer to generate source code that automatically configures the device to your specification and provides the high-level user module API functions.
