STMicroelectronics STM32F373V8T6

Overview

STM32F373V8T6 from STMicroelectronics is a 32-bit ARM® Cortex®-M4 microcontroller with FPU and MPU, operating up to 72 MHz, featuring 256 KB Flash, 32 KB SRAM, four ADCs (including three 16-bit sigma-delta), three 12-bit DACs, two rail-to-rail comparators, and integrated capacitive sensing-designed for precision analog signal acquisition in industrial sensor nodes and motor control interfaces.

For engineers reviewing the STM32F373V8T6 datasheet, STM32F373V8T6 pinout, STM32F373V8T6 application, or STM32F373V8T6 equivalent, key selection considerations include its dual ADC architecture (12-bit SAR + 16-bit SDADC), CAN 2.0B interface, USB 2.0 full-speed support, and 5 V-tolerant I/O capability across 45 pins-critical for mixed-voltage industrial HMI and power conversion monitoring systems.

Technical Context

The STM32F373V8T6 integrates a single-core Cortex-M4 with hardware floating-point unit and memory protection unit, enabling deterministic real-time control with DSP extensions. Its analog subsystem combines a 12-bit 1 µs SAR ADC (16 channels) and three independent 16-bit sigma-delta ADCs supporting up to 21 single-ended or 11 differential inputs-each with dedicated 2.2–3.6 V analog supply rails.

Clock management includes dual oscillators (4–32 MHz HSE and 32 kHz LSE), internal 8 MHz RC with x16 PLL, and 40 kHz LSI, feeding 17 timers-including two 32-bit general-purpose units and three 16-bit basic timers dedicated to DAC triggering-alongside RTC with alarm and periodic wakeup from Stop/Standby modes.

FAQ

What is the maximum operating frequency and core type of the STM32F373V8T6?

The STM32F373V8T6 features an ARM Cortex-M4 core with FPU and MPU, running at a maximum frequency of 72 MHz. It achieves 1.25 DMIPS/MHz (Dhrystone 2.1) and supports single-cycle multiplication and hardware division-enabling efficient execution of control algorithms and signal processing tasks without external coprocessors.

Does the STM32F373V8T6 support 5 V tolerant I/Os, and how many are available?

Yes, the STM32F373V8T6 supports 5 V tolerant I/Os on up to 45 pins-including PA0–PA15, PB0–PB15, PC0–PC5, PC10–PC15, PD0–PD7, PE0–PE15, and PF0–PF1. This allows direct connection to legacy 5 V peripherals and sensors without external level-shifting circuitry, simplifying system design in mixed-voltage industrial environments.

What analog peripherals are integrated, and what are their key resolution and channel counts?

The device integrates one 12-bit SAR ADC (16 channels, 1 µs conversion), three 16-bit sigma-delta ADCs (up to 21 single-ended or 11 differential channels), three 12-bit DACs, and two rail-to-rail comparators. Each SDADC has independent analog supply (2.2–3.6 V) and programmable gain, enabling high-SNR measurements for precision current/voltage monitoring in power electronics.

Is USB functionality self-contained, and does it require an external crystal?

Yes, the STM32F373V8T6 includes a full-speed USB 2.0 interface with an integrated PHY. It supports crystal-less operation using the internal 48 MHz oscillator, eliminating the need for an external 48 MHz crystal-reducing BOM count and board space while maintaining USB compliance for diagnostic, firmware update, and HID applications.
