EZ-Color devices combine the power and flexibility of Programmable System-on-Chip with Cypress's precise illumination signal modulation PrISM modulation technology providing lighting designers a fully customizable and integrated lighting solution platform. The EZ-Color family supports a range of independent LED channels from 4 channels at 32 bits of resolution each, up to 16 channels at 8 bits of resolution each. This enables lighting designers the flexibility to choose the LED array size and color quality. PSoC Designer software, with lighting specific drivers, can significantly cut development time and simplify implementation of fixed color points through temperature, optical, and LED binning compensation. EZ-Color's virtually limitless analog and digital customization enable simple integration of features in addition to intelligent lighting, such as CapSense, battery charging, image stabilization, and motor control during the development process. These features, along with Cypress's best-in-class quality and design support, make EZ-Color the ideal choice for intelligent HB LED control applications. Target Applications • LCD Backlight • Large Signs • General Lighting • Architectural Lighting • Camera/Cell Phone Flash • Flashlights The PSoC Core The PSoC Core is a powerful engine that supports a rich feature set. The core includes a CPU, memory, clocks, and configurable General Purpose I/O GPIO . The M8C CPU core is a powerful processor with speeds up to 68 MHz, providing a four MIPS 8-bit Harvard-architecture microprocessor. The CPU uses an interrupt controller with up to 20 vectors, to simplify programming of real time embedded events. Program execution is timed and protected using the included Sleep and watchdog timers WDT . Memory encompasses 16K of flash for program storage, 1K of SRAM for data storage, and up to 2K of EEPROM emulated using the flash. Program flash uses four protection levels on blocks of 64 bytes, allowing customized software IP protection. The EZ-Color family incorporates flexible internal clock generators, including a 24 MHz internal main oscillator IMO accurate to 8 percent over temperature and voltage. The 24 MHz IMO can also be doubled to 48 MHz for use by the digital system. A low power 32 kHz internal low speed oscillator ILO is provided for the sleep timer and WDT. The clocks, together with programmable clock dividers as a system resource , provide the flexibility to integrate almost any timing requirement into the EZ-Color device. In USB systems, the IMO self-tunes to ± accuracy for USB communication. EZ-Color GPIOs provide connection to the CPU, digital and analog resources of the device. Each pin’s drive mode may be selected from eight options, allowing great flexibility in external interfacing. Every pin can also generate a system interrupt on high level, low level, and change from last read. The Digital System The digital system is composed of four digital PSoC blocks. Each block is an 8-bit resource that can be used alone or combined with other blocks to form 8-, 16-, 24-, and 32-bit peripherals, which are called user module references. Digital peripheral configurations include: • PrISM 8- to 32-bit • Full speed USB 12 Mbps • PWMs 8- to 32-bit • PWMs with Dead band 8- to 24-bit • Counters 8- to 32-bit • Timers 8- to 32-bit • UART 8-bit with selectable parity • SPI master and slave • I2C slave and multi-master • Cyclical Redundancy Checker CRC /Generator 8- to 32-bit • IrDA • Generators 8- to 32-bit The digital blocks can be connected to any GPIO through a series of global buses that can route any signal to any pin. The buses also allow for signal multiplexing and for performing logic operations. This configurability frees your designs from the constraints of a fixed peripheral controller. Digital blocks are provided in rows of four, where the number of blocks varies by EZ-Color device family. This allows you the optimum choice of system resources for your application. Family resources are shown in the table titled EZ-Color Device Characteristics.

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 lets you to use more than 100 percent of PSoC's resources for an application. Page 7 of 49 CY8CLED04 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.
