General description

Infineon’ 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. PSoC? 4100PS 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

Features

? Programmable analog blocks

- Two dedicated analog-to-digital converters (ADC) including a 12-bit SAR ADC and a 10-bit single-slope ADC

- Four opamps, two low-power comparators, and a flexible 38-channel analog mux to create custom Analog

Front Ends (AFE)

- Two 13-bit voltage DACs

- Two 7-bit current DACs (IDACs) for general-purpose or capacitive sensing applications on any pin

? CAPSENSE? capacitive sensing

- Infineon’s fourth-generation CAPSENSE? Sigma-Delta (CSD) providing best-in-class signal-to-noise ratio

(SNR) and water tolerance

- Infineon-supplied software component makes capacitive sensing design easy

- Automatic hardware tuning (SmartSense?)
