Infineon/CYPRESS CY8C21123-24SXI

The PSoC family consists of many programmable system-on-chip controller devices. These devices are designed to replace multiple traditional MCU-based system components with a low cost single-chip programmable component. A PSoC device includes configurable blocks of analog and digital logic, and programmable interconnect. This architecture allows you to create customized peripheral configurations, to match the requirements of each individual application. Additionally, a fast CPU, Flash program memory, SRAM data memory, and configurable I/O are included in a range of convenient pinouts.
