Infineon/CYPRESS CY8C4126AXI-S423

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 analog and digital blocks with flexible automatic routing. The PSoC 4100S product family is a member of the PSoC 4 platform architecture. It is a combination of a microcontroller with standard communication and timing peripherals, a capacitive touch - sensing system (CAPSENSE) with best - in - class performance, programmable general - purpose continuous - time and switched - capacitor analog blocks, and programmable connectivity. PSoC 4100S products are upward compatible with members of the PSoC 4 platform for new applications and design needs.
