PSoC® 4 is a scalable and reconfigurable platform architecture for a family of programmable embedded system controllers with an ARM® Cortex®-M0 CPU. It combines programmable and reconfigurable analogue and digital blocks with flexible automatic routing. The PSoC 4200L product family, based on this platform, is a combination of a microcontroller with digital programmable logic, programmable analogue, programmable interconnect, secure expansion of memory off-chip, high-performance analogue-to-digital conversion, opamps with Comparator mode, and stand ard communication and timing peripherals. The PSoC 4200L products will be fully compatible with members of the PSoC 4 platform for new applications and design needs. The programmable analogue and digital subsystems allow flexibility and in-field tuning of the design.
