PSoC 3: CY8C34 Family Datasheet
Programmable System-on-Chip (PSoC )
General
Description
Psoc 3 Is A True Programmable Embedded System-on-chip, Integrating Configurable Analog And Digital
Peripherals, Memory, And A Microcontroller On A Single Chip. The Psoc 3 Architecture Boosts
Performance Through: 8051 Core Plus Dma Controller At Up To 50 Mhz Ultra Low Power With
Industry's Widest Voltage Range Programmable Digital And Analog Peripherals Enable Custom
Functions Flexible Routing Of Any Analog Or Digital Peripheral Function To Any Pin Psoc Devices
Employ A Highly Configurable System-on-chip Architecture For Embedded Control Design. They Integrate
Configurable Analog And Digital Circuits, Controlled By An On-chip Microcontroller. A Single Psoc
Device Can Integrate As Many As 100 Digital And Analog Peripheral Functions, Reducing Design Time,
board space, power consumption, and system cost while improving system quality.
