General Description

PSoC? 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.
