PSoC Functional Overview

The PSoC family consists of many Mixed-Signal Array with On-Chip Controller devices. These devices are designed to replace multiple traditional MCU-based system components with one low cost single-chip programmable component. A PSoC device includes configurable blocks of analog and digital logic, and programmable interconnect. This architecture enables the user to create customized peripheral configurations, to match the requirements of each individual application. Additionally, a fast CPU, Flash program memory, SRAM data memory, and configurable IO are included in a range of convenient pinouts.

The PSoC architecture, shown in Figure 1, consists of four main areas: the Core, the System Resources, the Digital System, and the Analog System. Configurable global bus resources allow combining all the device resources into a complete custom system. Each CY8C21x34 PSoC device includes four digital blocks and four analog blocks. Depending on the PSoC package, up to 28 general purpose IO (GPIO) are also included. The GPIO provide access to the global digital and analog inter- connects.

The PSoC Core

The PSoC 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 the following additional capabilities:

Digital clocks to increase the flexibility of the PSoC mixed-signal arrays.

I2C functionality to implement an I2C master and slave.

An internal voltage reference, MultiMaster, that provides an absolute value of 1.3V to a number of PSoC subsystems.

A switch mode pump (SMP) that generates normal operating voltages off a single battery cell.

Various system resets supported by the M8C.

The Digital System consists of an array of digital PSoC blocks that may be configured into any number of digital peripherals. The digital blocks are connected to the GPIO through a series of global buses that can route any signal to any pin, freeing designs from the constraints of a fixed peripheral controller.

The Analog System consists of four analog PSoC blocks, supporting comparators and analog-to-digital conversion up to 8 bits in precision.

The Digital System

The Digital System consists of 4 digital PSoC blocks. Each block is an 8-bit resource that is 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 the following.

PWMs (8 to 32 bit)

PWMs with Dead band (8 to 32 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/Generator (8 to 32 bit)

IrDA

Pseudo Random Sequence Generators (8 to 32 bit)

The digital blocks are 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 PSoC device family. This allows the optimum choice of system resources for your application. Family resources are shown in Table 1 on page 4.
