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.
