STMicroelectronics STM32373C-EVAL

Overview

STM32373C-EVAL from STMicroelectronics is an evaluation board built around the STM32F373VCT6 ARM Cortex-M4 microcontroller, featuring dual 16-bit sigma-delta ADCs, three 12-bit DACs, USB FS, CAN 2.0A/B, HDMI CEC, and integrated ST-LINK/V2 debugger. It supports ECG, pressure, and PT100 sensor interfacing, 240×320 TFT LCD, MicroSD card, and I²C-connected temperature sensor/EEPROM/RF EEPROM for rapid prototyping of mixed-signal embedded applications.

For engineers reviewing the STM32373C-EVAL datasheet, STM32373C-EVAL pinout, STM32373C-EVAL application, or STM32373C-EVAL equivalent, this board serves as a validated hardware reference for evaluating STM32F373xx peripheral integration-including sigma-delta ADC signal chains, audio I²S DAC output, IrDA transceiver timing, and multi-interface sensor fusion with CAN and HDMI-CEC control.

Technical Context

The board implements full peripheral access to the STM32F373VCT6's 100-pin LQFP package, including dedicated routing for its three independent SPI interfaces (one driving TFT LCD, one for MicroSD, one for daughter board expansion), two I²C buses (one shared by temperature sensor, EEPROM, and RF EEPROM), and three USARTs (one configured for RS-232 Flash loader communication).

Hardware-level support includes JTAG/SWD and ETM trace debugging via embedded ST-LINK/V2, adjustable MCU core voltage (2.0–3.6 V), RTC with backup battery, touch slider with capacitive sensing firmware, and analog front-end conditioning for ECG, pressure, and PT100 sensors feeding the 16-bit sigma-delta ADC inputs.

FAQ

Does STM32373C-EVAL support STM32F3x8 MCUs?

No. The board is explicitly designed for STM32F373xx MCUs and does not support STM32F3x8 devices due to incompatible 1.65–1.95 V supply requirements. Its voltage regulation is fixed at 3.3 V or adjustable 2.0–3.6 V, matching the F373's operational range.

What sensors are directly connected and conditioned for analog acquisition?

The board provides hardware-level signal conditioning for ECG, pressure, and PT100 temperature sensors, all routed to dedicated inputs of the STM32F373VCT6's 16-bit sigma-delta ADCs. An onboard microphone amplifier also feeds the 12-bit ADC channel.

Is HDMI CEC functionality fully implemented on the board?

Yes. Two HDMI connectors include DDC and CEC lines, with CEC signals routed to the STM32F373VCT6's dedicated CEC controller peripheral, enabling compliant HDMI-CEC command transmission and reception without external level-shifting.

Can the ST-LINK/V2 on board program external STM32 targets?

Yes. The embedded ST-LINK/V2 supports SWD/JTAG programming and debugging of external STM32 MCUs via the SWDIO and SWCLK pins on the board's extension headers, using standard ST-LINK firmware and STM32CubeProgrammer software.
