Infineon CY8C4013SXI-400, 32bit ARM Cortex M0 Microcontroller, PSoC 4000, 16MHz, 8 kB Flash, 8-Pin SOIC

The Cypress Semiconductor PSoC 4 (Programmable Embedded System-on-Chip) family contain an ARM Cortex-M0 processor both product families 4100 and the 4200 platform architecture feature a combination of a microcontroller with op amps with Comparator mode, digital programmable logic, A/D converter as well as communication and timing devices. In the PSoC4 platform the controllers are compatible with each other for designing and new applications.
