These devices are designed to replace multiple traditional MCU-based system components with one low cost single-chip programmable device. PSoC devices include configurable blocks of analog and digital logic, as well as programmable interconnects. This architecture enables the user to create customized peripheral configurations that match the requirements of each individual application. Additionally, a fast CPU, flash program memory, SRAM data memory, and configurable I/O are included in a range of convenient pinouts and packages. The PSoC architecture, shown in the Block Diagram on page 1, consists of four main areas: PSoC core, digital system, analog system, and system resources. Configurable global busing allows the combining of all the device resources into a complete custom system. The PSoC family can have up to five I/O ports connecting to the global digital and analog interconnects, providing access to eight digital blocks[1] and six analog blocks. PSoC Core The PSoC core is a powerful engine that supports a rich feature set. The core includes a CPU, memory, clocks, and configurable GPIO. The M8C CPU core is a powerful processor with speeds up to 24 MHz (up to 12 MHz for E-grade devices), providing four MIPS (two MIPS for E-grade devices) 8-bit Harvard architecture micro- processor. The CPU uses an interrupt controller to simplify the programming of real time embedded events. Program execution is timed and protected using the included Sleep Timer and Watch Dog Timer (WDT). Memory encompasses 16 KB of flash (8 KB for CY8C21x45 devices) for program storage, 1 KB of SRAM (512 bytes for CY8C21x45 devices) for data storage, and EEPROM emulation using the flash. Program flash uses four protection levels on blocks of 64 bytes, allowing customized software IP protection. The PSoC device incorporates flexible internal clock generators, including a 24-MHz internal main oscillator (IMO). For A-grade devices 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. If crystal accuracy is required, the 32.768 kHz external crystal oscillator (ECO) is available for use as a RTC, and can optionally generate a crystal-accurate 24-MHz system clock using a PLL. The clocks, together with programmable clock dividers (as a system resource), provide the flexibility to integrate almost any timing requirement into the PSoC device. PSoC 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. Each pin can also generate a system interrupt. Digital System The digital system is composed of eight digital PSoC blocks. Each block is an 8-bit resource that may be used alone or combined with other blocks to form 8-, 16-, 24-, and 32-bit peripherals, which are called user modules. Figure 1. Digital System Block Diagram[1] Digital peripheral configurations are: ■ PWMs (8- to 32-bit) ■ PWMs with deadband (8- to 32-bit) ■ Counters (8- to 32-bit) ■ Timers (8- to 32-bit) ■ One-shot and multi-shot modules ■ Full or half-duplex 8-bit UART with selectable parity (up to two full-duplex or four half-duplex) ■ SPI master and slave (up to four total) with programmable data length from 8 to 16 bits. ■ Shift register (1- to 32-bit) ■ I 2C master, slave, or multi-master (one available) ■ CRC/generator (16-bit) ■ IrDA (up to two) ■ PRS generators (8- to 32-bit) Note 1. CY8C22x45 devices have 2 digital rows with 8 digital blocks. CY8C21x45 devices only have 1 digital row with 4 digital blocks.
