Product details

48-LQFP footprint and mixed-signal ADC edge

The STM32F373C8T6 packs an ARM Cortex-M4 core running at 72 MHz into a 48-LQFP (7x7 mm) package — the 0.5 mm pitch demands a 4-layer board for clean fan-out of the 36 I/O, but the small footprint keeps the BOM density manageable on space-constrained analog front-end designs. What sets this part apart in the STM32F3 line is the data converter block: three independent 16-bit sigma-delta ADCs alongside a single 12-bit SAR ADC and three 12-bit DACs. That means simultaneous sampling on three analog channels at 16-bit resolution without the latency of a multiplexed converter — a genuine edge for multi-phase current sensing or vibration monitoring.

Frequently asked questions

What is STM32F373C8T6's listed speed and core?

The 16-bit sigma-delta ADCs are the headline peripheral — three independent channels for simultaneous high-resolution sampling.

Will STM32F373C8T6 drop into a board designed for STM32L151CBU6A?

No — they are not pin-compatible. The STM32L151CBU6A comes in a 48-UFQFPN package with a different pinout and runs a Cortex-M3 at 32 MHz. The STM32F373C8T6 uses a 48-LQFP footprint and offers higher clock speed plus the sigma-delta ADC block, but a board respin is required.
