Product details

The STM32F373CBT7: ARM Cortex-M4 core runs at 72 MHz. Program memory is 128 KB of Flash, backed by 24 KB of SRAM (24K x 8). The distinguishing feature is the data-converter subsystem: a 12-bit SAR ADC plus three independent 16-bit sigma-delta ADCs, alongside three 12-bit DACs.

Package and footprint — 48-LQFP with 36 I/O

Connectivity and peripherals — CAN, USB, and multiple serial interfaces

The evidence lists UART/USART as a group without a per-interface count, so the exact number of UARTs is not confirmed here — the STM32F373 reference manual (not in evidence) typically provides two USARTs and one UART. DMA and I²S are present for streaming audio or high-speed data transfer without CPU intervention.
