The ST STM32F373RCT6TR is a 32-bit ARM Cortex-M4 MCU from the STM32F3 series, clocked at 72 MHz with a single-cycle multiply and floating-point unit. It carries 256 KB of Flash and 32 KB of RAM, enough for moderate sensor-fusion or motor-control firmware. The 64-LQFP package (10x10 mm) is a common footprint across the STM32F3 value line, making board reuse straightforward if you later shift density.
Sigma-delta ADCs — what they mean for the BOM
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.
Lifecycle and sourcing reality
The lifecycle status is flagged as end-of-life hot, meaning the manufacturer's production window is closing. No official successor order code appears in the record. 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. We can source and quote it to order against an RFQ; availability and current pricing are confirmed at quote time.
Connectivity and peripheral set
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.
