PRELIMINARY 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 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 Gpio Pin. The Cy8c34 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 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. 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 Cy8c34 Family Provides Unparalleled
Opportunities For Analog And Digital Bill Of Materials Integration While Easily Accommodating Last
minute design changes through simple firmware updates.
