STMicroelectronics STM32F373VCH6

Overview

STM32F373VCH6 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 feedback systems.

For engineers reviewing the STM32F373VCH6 datasheet, STM32F373VCH6 pinout, STM32F373VCH6 application, or STM32F373VCH6 equivalent, key selection considerations include its dual ADC architecture (12-bit SAR + 16-bit SDADC), 5 V-tolerant I/O capability on 45 pins, CAN 2.0B interface, USB 2.0 full-speed support, and RTC with calendar alarm-critical for mixed-signal embedded systems requiring high-resolution measurement and real-time connectivity.

Technical Context

The STM32F373VCH6 integrates a single-core Cortex-M4 CPU with hardware floating-point unit and memory protection unit, enabling deterministic DSP execution and secure peripheral isolation. Its analog subsystem combines a 12-bit 1 µs SAR ADC (16 channels) with three independent 16-bit sigma-delta ADCs supporting up to 21 single-ended inputs-each with dedicated 2.2–3.6 V analog supply rails and programmable gain.

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 a flexible prescaler tree that synchronizes timers, ADCs, and communication peripherals. The 17-timer suite includes two 32-bit general-purpose timers, four basic 16-bit timers for DAC triggering, and independent/system watchdogs-all supporting PWM, input capture, and quadrature encoding.

FAQ

What is the maximum operating frequency and supported voltage range for the STM32F373VCH6?

The STM32F373VCH6 operates at a maximum CPU frequency of 72 MHz and supports a supply voltage range of 2.0 V to 3.6 V for both VDD and VDDA domains. Its internal voltage regulator and programmable voltage detector ensure stable operation across this range, with validated performance in all low-power modes including Stop and Standby.

Does the STM32F373VCH6 support USB device functionality without external components?

Yes-the STM32F373VCH6 integrates a full-speed USB 2.0 device interface with an on-chip transceiver, internal pull-up resistors, and dedicated DP/DM pins. No external PHY or termination resistors are required, enabling plug-and-play USB connectivity for firmware updates, HID devices, or CDC virtual COM ports.

How many analog-to-digital converters does the STM32F373VCH6 include, and what are their key distinctions?

The STM32F373VCH6 includes four ADC subsystems: one 12-bit SAR ADC (16 channels, 1 µs conversion) and three independent 16-bit sigma-delta ADCs (up to 21 single-ended channels). The SAR ADC targets fast transient capture, while the SDADCs provide high-resolution, noise-immune measurements ideal for current sensing and energy metering.

Is the STM32F373VCH6 pin-compatible with other STM32F373xx variants in the same package?

Yes-STM32F373VCH6 shares identical UFBGA100 pinout and electrical characteristics with other STM32F373xx members in the same package (e.g., STM32F373VCT6), differing only in Flash size (256 KB vs. 128 KB) and temperature grade. This allows seamless migration within the same footprint during design optimization or qualification.
