Programmable System-on-Chip (PSOC™ 1)

Infineon Technologies Programmable System-on-Chip (PSOC™ 1) family consists of modules designed to replace multiple traditional MCU-based system components with a single cost-effective, single-chip programmable device. The Infineon PSOC devices include configurable blocks of analog and digital logic and programmable interconnects. This architecture enables the user to create customized peripheral configurations that match the requirements of each individual application. Additionally, a fast CPU, Flash program memory, SRAM data memory, and configurable IO are included in a range of convenient pinouts and packages.
