STMicroelectronics STM32072B-EVAL

Overview

STM32072B-EVAL from STMicroelectronics is an evaluation board built around the STM32F072VBT6 ARM Cortex-M0 microcontroller, featuring 128KB Flash, 16KB SRAM, USB Full-Speed, CAN 2.0A/B, 12-bit ADC/DAC, two I²C, two SPI, four USART, RTC with backup battery, and touch sensing-designed for rapid prototyping of industrial HMI, sensor gateway, and USB-CDC/DFU firmware development.

For engineers reviewing the STM32072B-EVAL datasheet, STM32072B-EVAL pinout (via extension headers), STM32072B-EVAL application (e.g., USB-to-RS485 bridge or audio DAC/ADC validation), or STM32072B-EVAL equivalent (e.g., STM32F072B-DISCO), this page delivers verified hardware capabilities, peripheral coverage, and supply-chain support without reliance on generic evaluation platform assumptions.

Technical Context

The board integrates ST-LINK/V2 as an embedded in-circuit debugger and programmer, supporting SWD interface and full-speed USB communication with host PCs. It provides direct access to all MCU peripherals-including CAN transceiver, IrDA, RS232/RS485 level shifters, stereo audio codec interface, and 240×320 TFT LCD via SPI-enabling real-time peripheral stress testing and firmware bring-up.

Hardware flexibility includes dual power options (fixed 3.3 V or adjustable 1.65–3.6 V), four user LEDs, joystick + tactile buttons, LDR, potentiometer, Smart Card slot, HDMI DDC/CEC, and MicroSD card interface-all routed to STM32F072VBT6 GPIOs and peripheral controllers with documented signal integrity considerations.

FAQ

Does STM32072B-EVAL support CAN FD?

No. The board implements CAN 2.0A/B compliant physical layer only, using the STM32F072VBT6's built-in bxCAN controller. CAN FD requires higher clock rates and enhanced message filtering not supported by this MCU variant or its associated transceiver circuitry.

Can the on-board ST-LINK/V2 program other STM32 devices?

Yes. ST-LINK/V2 on STM32072B-EVAL supports programming and debugging of other STM32 MCUs via SWD interface, provided target voltage is within 1.65–3.6 V and SWDIO/SWCLK pins are correctly connected-no additional firmware update required.

Is the TFT LCD display resistive or capacitive?

The 240×320 TFT LCD is a passive matrix display without integrated touch panel; it is driven exclusively via SPI and does not include resistive or capacitive touch sensing-touch input is handled separately by dedicated touch-sensing buttons on the board.

What is the maximum MicroSD card capacity supported?

The board supports SPI-mode MicroSD cards up to 2 GB as specified in the data brief; larger cards may function if formatted as FAT16, but compatibility is not guaranteed due to driver limitations in the reference firmware and lack of SDHC protocol stack in default demo code.
