Three 16-bit sigma-delta ADCs sit alongside a single 12-bit SAR ADC and three 12-bit DACs. That analog front-end is unusual for a 64-pin MCU — it lets you read strain gauges, thermocouples, or current-shunt signals directly, without an external sigma-delta converter. If your design needs high-resolution low-speed measurements plus a faster SAR channel for control-loop feedback, this part covers both in one chip. The lifecycle status is flagged as end-of-life hot, meaning the manufacturer's production window is closing. If this part is on your BOM, the smart move is to secure a last-time-buy quantity now — once the factory run ends, the only channel will be independent surplus. On the communication side: CANbus, I²C, SPI, UART/USART, USB, plus IrDA and LINbus. That covers most industrial and automotive-adjacent bus requirements without external transceivers (except for CAN and LIN physical layers). The 52 GPIOs in the 64-LQFP leave enough headroom for a modest sensor array or a mixed I/O panel. DMA and PWM are built in, so motor-timer or waveform-generation tasks don't steal CPU cycles.","metaTitle":"ST STM32F373RCT6TR ARM Cortex-M4 MCU, 72 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F373RCT6TR 32-bit MCU, 72 MHz Cortex-M4F core, 256 KB Flash, 32 KB RAM, 3x16b sigma-delta ADC, 64-LQFP.
