PSoC® 3: CY8C34 Family
Data Sheet
Programmable System-on-Chip (PSoC®)
General Description
With its unique array of configurable blocks, PSoC® 3 is a true system level solution providing microcontroller unit (MCU), memory,
analog, and digital peripheral functions in a single chip. The CY8C34 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 CY8C34 family can handle dozens of data acquisition channels and analog inputs on
every general-purpose input/output (GPIO) pin. The CY8C34 family isalso a high-performance configurable digital system with some
part numbers including interfaces such as USB, multimaster inter-integrated circuit (I2C), and controller area network (CAN). In
addition to communication interfaces, the CY8C34 family has an easy to configure logic array, flexible routing to all I/O pins, and a
high-performance single cycle 8051 microprocessor core. You can easily create system-level designs using a rich library of prebuilt
components and boolean primitives using PSoC Creatorâ¢, a hierarchical schematic design entry tool. The CY8C34 family provides
unparalleled opportunities for analog and digital bill of materials integration while easily accommodating last minute design changes
through simple firmware updates.
