PSoC®5: CY8C55 Family Data Sheet
Programmable System-on-Chip (PSoC®)
General Description
With its unique array of configurable blocks, PSoC®5 is a true system level solution providing 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,
multi-master I2C, and CAN. 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 ARM® 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.
