STMicroelectronics STM32F373VCH7

Overview

STM32F373VCH7 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 with hardware parity, four 12-/16-bit ADCs (including three sigma-delta), three 12-bit DACs, two rail-to-rail comparators, and integrated capacitive sensing for human-machine interface applications in industrial control and medical instrumentation.

For engineers reviewing the STM32F373VCH7 datasheet, STM32F373VCH7 pinout, STM32F373VCH7 application, or STM32F373VCH7 equivalent, key selection considerations include its dual ADC architecture (12-bit SAR + 16-bit sigma-delta), CAN 2.0B interface, USB 2.0 full-speed support, and 5 V-tolerant I/O capability across 45 pins - critical for mixed-voltage system integration and precision analog front-end design.

Technical Context

The STM32F373VCH7 implements a tightly coupled ARM Cortex-M4 core with single-cycle MAC, hardware divide, and IEEE-754-compliant FPU for real-time signal processing. Its memory subsystem includes 256 KB of embedded Flash with error correction and 32 KB SRAM with parity checking, enabling robust operation in safety-critical environments.

Analog subsystem integration includes three independent 16-bit sigma-delta ADCs (up to 21 single-ended channels), one 12-bit SAR ADC (16-channel, 1 µs conversion), three 12-bit DACs, and two fast comparators with programmable hysteresis - all sharing dedicated analog supplies (VDDA: 2.2–3.6 V, VREF+ up to 3.6 V) for high-precision measurement and closed-loop control.

FAQ

What is the maximum operating frequency and supported voltage range for STM32F373VCH7?

The STM32F373VCH7 operates at up to 72 MHz with a supply voltage range of 2.0 V to 3.6 V for VDD and 2.2 V to 3.6 V for VDDA. Its internal 8 MHz RC oscillator can be multiplied via PLL to achieve full-speed operation, and the programmable voltage detector monitors VDD down to 2.2 V for safe brown-out response.

Does STM32F373VCH7 support USB device functionality without external components?

Yes - the STM32F373VCH7 integrates a full-speed USB 2.0 transceiver with internal pull-up resistors and dedicated USB DP/DM pins. It supports device-mode operation (not host) and requires only a USB connector and appropriate ESD protection; no external PHY or level shifter is needed for standard USB CDC or HID implementations.

How many analog inputs can be simultaneously sampled using the integrated ADCs?

The STM32F373VCH7 supports concurrent sampling across its four ADC subsystems: one 12-bit SAR ADC (16 channels) and three 16-bit sigma-delta ADCs (up to 21 total single-ended channels). While true hardware simultaneity is limited to groups within each ADC, synchronized triggering via timer events enables tightly coordinated multi-channel acquisition for phase-matched measurements.

Is the STM32F373VCH7 pin-compatible with other STM32F373xx variants in UFBGA100?

Yes - all STM32F373xx devices in the UFBGA100 package (e.g., STM32F373VCH7, STM32F373VCT6) share identical pinouts and mechanical footprint. Differences lie in Flash/SRAM size and factory-programmed options, not I/O assignment or electrical behavior - enabling drop-in replacement during design iteration or qualification.
