General description
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. PSoC™ 4100S Max is a member of the PSoC™ 4 platform architecture. It is a combination of a microcontroller
with standard communication and timing peripherals, a capacitive sensing system with best-in-class
performance, programmable general-purpose continuous-time analog blocks, and programmable connectivity.
PSoC™ 4100S Max products are compatible with members of the PSoC™ 4 platform for new applications and
design needs.
