Industrial temperature grade (-40 to 85 °C) covers outdoor enclosures, engine-bay-adjacent electronics, and cold-storage environments — the 44-TQFP package dissipates heat through the exposed pad to the PCB copper. ## Memory budget and peripheral fit for control loops 32 KB of on-chip flash leaves room for a real-time control loop, a communication stack (I²C, SPI, UART, LIN), and a small RTOS kernel — 4 KB SRAM is tight for large buffers but sufficient for sensor data aggregation and state machines. The 8-channel 12-bit SAR ADC samples at rates suitable for motor-current sensing or multi-channel analog front-ends; the two IDAC outputs drive external sensor excitation or closed-loop biasing without an external DAC.","metaTitle":"CY8C4125AXI-473 Infineon PSoC 4 MCU, 24 MHz, 44-TQFP","metaDescription":"Active-production ARM Cortex-M0 MCU, 32 KB flash, 4 KB RAM, 1.71-5.5 V, -40 to 85 °C. 36 GPIO, 8x12b SAR ADC, 2x IDAC.
