5 CY8C55 Family Datasheet

Programmable System-on-Chip

With its unique array of configurable blocks, 5 is a true system-level solution providing microcontroller unit MCU , memory, analog, and digital peripheral functions in a single chip. The CY8C55 family offers a modern method of signal acquisition, signal processing, and control with high accuracy, high bandwidth, and high flexibility. Analog capability spans the range from thermocouples near DC voltages to ultrasonic signals. The CY8C55 family can handle dozens of data acquisition channels and analog inputs on every GPIO pin. The CY8C55 family is also a high-performance configurable digital system with some part numbers including interfaces such as USB, and multimaster I2C. In addition to communication interfaces, the CY8C55 family has an easy to configure logic array, flexible routing to all I/O pins, and a high-performance 32-bit Cortex -M3 microprocessor core. Designers can easily create system-level designs using a rich library of prebuilt components and boolean primitives using PSoC Creator , a
hierarchical schematic design entry tool. The CY8C55 family provides unparalleled opportunities for analog and digital bill of materials integration while easily accommodating last minute design changes through simple firmware updates.

Architectural Overview

Introducing the CY8C55 family of ultra low power, flash Programmable System-on-Chip PSoC devices, part of a scalable 8-bit PSoC 3 and 32-bit PSoC 5 platform. The CY8C55 family provides configurable blocks of analog, digital, and interconnect circuitry around a CPU subsystem. The combination of a CPU with a flexible analog subsystem, digital subsystem, routing, and I/O enables a high level of integration in a wide variety of consumer, industrial, and medical applications.

Notes Analog blocks support a wide variety of functionality including TIA, PGA, and mixers. See Example Peripherals on page 31 for more information on how analog blocks
can be used. UDBs support a wide variety of functionality including SPI, LIN, UART, timer, counter, PWM, PRS, and others. Individual functions may use a fraction of a UDB or
multiple UDBs. Multiple functions can share a single UDB. See Example Peripherals on page 31 for more information on how UDBs can be used. The I/O Count includes all types of digital I/O GPIO, SIO, and the two USB I/O. See I/O System and Routing on page 24 for details on the functionality of each of
these types of I/O. The device ID has three major fields. The most significant nibble left digit is the version, followed by a 2 byte part number, and a 3 nibble manufacturer ID.
