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 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.
■
Low Voltage Detection (LVD) interrupts can signal the application of falling voltage levels, while the advanced POR (power on reset) circuit eliminates the need for a system supervisor. The 5V maximum input, 1.8/2.5/3V-selectable output, low-dropout regulator (LDO) provides regulation for IOs. A register controlled bypass mode allows the user to disable the LDO. Standard Cypress PSoC IDE tools are available for debugging the enCoRe V family of parts.
■
■
Getting Started
The quickest path to understanding the enCoRe V silicon is by reading this data sheet and using the PSoC Designer Integrated Development Environment (IDE). This data sheet is an overview of the enCoRe V integrated circuit and presents specific pin, register, and electrical specifications. For up-to-date ordering, packaging, and electrical specification information, reference the latest enCoRe V device data sheets on the web at http://www.cypress.com.
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.
Development Kits
Development Kits are available from the following distributors: Digi-Key, Avnet, Arrow, and Future. The Cypress Online Store contains development kits, C compilers, and all accessories for PSoC development.

Go to http://www.cypress.com, click on Design Support located on the left side of the web page, and select Technical Training for more details.
Additional System Resources
System resources, some of which have been previously listed, provide additional capability useful to complete systems. Additional resources include low voltage detection and power on reset. Brief statements describing the merits of each system resource are presented below.
■
Full-speed USB (12 Mbps) with nine configurable endpoints and 512 bytes of dedicated USB RAM. No external components are required except two series resistors. It is specified for commercial temperature USB operation. For reliable USB operation, ensure the supply voltage is between 4.35V and 5.25V, or around 3.3V. 10-bit on-chip ADC shared between system performance manager (used to calculate parameters based on temperature for flash write operations) and the user. The I2C slave/SPI master-slave module provides 50/100/400 kHz communication over two wires. SPI communication over 3 or 4 wires runs at speeds of 46.9 kHz to 3 MHz (lower for a slower system clock). In the case of I2C slave mode, the hardware address recognition feature reduces the already low power consumption by eliminating the need for CPU intervention until a packet addressed to the target device has been received.

Development Tools
PSoC Designer is a Microsoft Windows-based, integrated development environment for the Programmable System-on-Chip (PSoC) devices. The PSoC Designer IDE and application runs on Windows NT 4.0, 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 1. PSoC Designer Subsystems
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
PSoC Designer Software Subsystems
Device Editor The device editor subsystem allows the user to select different onboard analog and digital components called user modules
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.

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.
Application Editor
Project Manager Source Code Editor Build Manager
Build All
Debugger
Interface to ICE Storage Inspector Event & Breakpoint Manager
The next step is to write your main program, and any sub-routines using PSoC Designer’s Application Editor subsystem. The Application Editor includes a Project Manager that allows you to open the project source code files (including all generated code files) from a hierarchal view. The source code editor provides syntax coloring and advanced edit features for both C and assembly language. File search capabilities include simple string searches and recursive “grep-style” patterns. A single mouse click invokes the Build Manager. It employs a professional-strength “makefile” system to automatically analyze all file dependencies and run the compiler and assembler as necessary. Project-level options control optimization strategies used by the compiler and linker. Syntax errors are displayed in a console window. Double clicking the error message takes you directly to the offending line of source code. When all is correct, the linker builds a HEX file image suitable for programming. The last step in the development process takes place inside the PSoC Designer’s Debugger subsystem. The Debugger downloads the HEX image to the In-Circuit Emulator (ICE) where it runs at full-speed. Debugger capabilities rival those of systems costing many times more. In addition to traditional single-step, run-to-breakpoint and watch-variable features, the Debugger provides a large trace buffer and allows you define complex breakpoint events that include monitoring address and data bus values, memory locations and external signals.

Register Reference
The section discusses the registers of the enCoRe V device. It lists all the registers in mapping tables, in address order.
Register Mapping Tables
The enCoRe V device has a total register address space of 512 bytes. The register space is also referred to as IO 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.
Register Conventions
The register conventions specific to this section and the Register Reference chapter are listed in the following table. Table 4.

This is automatically the case if the device does not stretch the LOW period of the SCL signal. If such device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line trmax + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-Mode I2C-bus specification) before the SCL line is released.
