PSoC™ 4100S: Intelligent Analog Integration

The PSoC™ 4100S delivers intelligent analog integration through programmable analog blocks and CAPSENSE™ technology for HMI

The PSoC™ 4100S family adds intelligent analog integration through programmable analog blocks. These Programmable Analog Blocks can be configured to create custom Analog Front Ends (AFEs) and signal conditioning circuits with opamps and filters.

Infineon CAPSENSE™ solutions enable designers to bring elegant, reliable, and easy-to-use capacitive touch sensing functionality to your design, via CAPSENSE™ Middleware part of  ModusToolbox™ software and our PSoC™ 4 and PSoC™ 6  microcontroller portfolio.

Infineon's PSoC™ 4 family is a  configurable platform architecture based on 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.
