PSoC® 3: CY8C32 Family Data Sheet
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.
