PSOC™ (Programmable System-on-Chip)

Infineon Technologies PSOC™ (Programmable System-on-Chip) is a programmable embedded design platform that integrates discrete analog and programmable logic, memory, and a microcontroller. Easy-to-use software tools, like the PSOC Creator Integrated Design Environment, simplify the design and debugging of analog front ends and digital glue logic while accelerating complete system designs. The PSOC comes in four MCU options for 8-bit and 32-bit applications, ranging from the cost-optimized 8-bit M8C to the high-performance ARM Cortex-M3.
