CY8C4125LQI-S423

Infineon Technologies

CY8C4125LQI-S423 is a 32-bit Arm Cortex-M0+ microcontroller from Infineon PSoC 4 4100S family, running at up to 24 MHz with 32 KB Flash and 4 KB SRAM in a 40-pin QFN package. It offers a 12-bit SAR ADC alongside a 10-bit ADC, CapSense touch sensing and serial communication blocks, operating from 1.71 V to 5.5 V over the industrial -40°C to +85°C range with 34 GPIOs. Selection advice: the S423 denotes the S-Series 4100S feature set — note this is the M0+ based 4100S, not the M0 based PSoC 4100 (e.g., CY8C4125LQI-483); firmware and PSoC Creator device selection differ between M0 and M0+ cores. Match the full ordering code.
