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:
ï® 8051 core plus DMA controller at up to 50 MHz
ï® Ultra low power with industry's widest voltage range
ï® Programmable digital and analog peripherals enable custom functions
ï® 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.
