Infineon, 32bit ARM Cortex M0, CY8C4100 Microcontroller, 24MHz, 128 kB Flash, 56-Pin QFN

PSoC® 4 is a scalable and reconfigurable platform architecture for a family of mixed-signal programmable embedded system controllers with an ARM® Cortex™-M0 CPU. It combines programmable and reconfigurable analog and digital blocks with flexible automatic routing. The PSoC 4100 product family, based on this platform, is a combination of a microcontroller with digital programmable logic, high-performance analog-to-digital conversion, opamps with Comparator mode, and standard communication and timing peripherals.

32-bit MCU Sub-system:
24-MHz ARM Cortex-M0 CPU with single-cycle multiply
Up to 32 kB of flash with Read Accelerator
Up to 4 kB of SRAM
