The 16-channel 12-bit ADC and dual 12-bit DAC let the chip handle sensor acquisition and analog output without an external converter. 51 general-purpose I/O lines are available in the 64-LQFP package (10x10 mm, 0.5 mm pitch). The LQFP footprint is a standard layout — no fine-pitch rework required, and the exposed paddle aids thermal transfer to the PCB copper plane.","metaTitle":"STM32L475RCT3 STM32 MCU, 80 MHz Cortex-M4, 256 KB Flash","metaDescription":"STMicroelectronics STM32L475RCT3 ARM Cortex-M4 MCU, 80 MHz, 256 KB flash, 128 KB RAM, 1.71-3.6 V, -40 to +125 °C.
