5LP: CY8C52LP Family
Programmable System-on-Chip (PSoC
Cypress Semiconductor Corporation 198 Champion Court San Jose, CA 95134-1709 408-943-2600
Document Number: 001-84933 Rev. *I Revised November 30,
General Description
5LP is a true programmable embedded system-on-chip, integrating configurable analog and digital peripherals, memory, and
a microcontroller on a single chip. The PSoC 5LP architecture boosts performance through:
32-bit ARM Cortex-M3 core plus DMA controller at up to 80 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.
