Product details

Overview

STM320518-EVAL from STMicroelectronics is an evaluation board built around the STM32F051R8T6 32-bit ARM Cortex-M0 microcontroller in 64-pin LQFP, featuring 64 KB Flash, 8 KB SRAM, 12-bit ADC/DAC, two I²C, two SPI, two USART, two GP comparators, touch sensing, CEC, and integrated ST-LINK/V2 debugger. It supports full peripheral evaluation including TFT LCD, MicroSD, RS-232/RS-485, IrDA, IR transceivers, HDMI CEC, motor control, temperature/LDR/linear sensors, and audio I/O.

For engineers reviewing the STM320518-EVAL datasheet, STM320518-EVAL pinout, STM320518-EVAL application, or STM320518-EVAL equivalent, this board serves as a complete development platform for rapid prototyping of embedded control, human-machine interface, industrial connectivity, and sensor-rich IoT edge nodes using the STM32F051 series.

Technical Context

The board implements a dual-power architecture with configurable VDD (fixed 3.3 V or adjustable 2.0–3.6 V) and independent VDDA (fixed 3.3 V), enabling precise analog measurement and low-power MCU operation. It integrates ST-LINK/V2 via CN13 (USB Type-B) for SWD-based programming and debugging of the onboard STM32F051R8T6.

Hardware resources are mapped across 14 dedicated connectors-including CN1 (motor control), CN3/CN4 (HDMI sink/source with CEC/DDC), CN7 (RS-232/RS-485), CN10/CN9 (standard/high-density SWD), CN14 (MicroSD), and CN5/CN6 (extension headers)-enabling modular expansion and system-level validation of communication, timing, power, and signal chain subsystems.

FAQ

Does STM320518-EVAL include the STM32F051R8T6 microcontroller pre-soldered?

Yes, the STM32F051R8T6 MCU is permanently mounted in a 64-pin LQFP package on the board. It is not socketed or replaceable. All peripherals-including ADC, DAC, comparators, timers, and communication interfaces-are directly routed to this MCU and fully functional out-of-box with preloaded demonstration firmware.

Can STM320518-EVAL be powered solely via the ST-LINK/V2 USB connection?

Yes-CN13 (USB Type-B connector) supplies 5 V at up to 500 mA to power both the ST-LINK/V2 circuitry and the STM32F051R8T6 target MCU when JP8 is configured for "STlk" mode. This eliminates the need for an external power adapter during development and debugging sessions.

What software tools are supported for firmware development on this board?

The board is natively supported by ST's STM32CubeIDE, STM32CubeMX, and STM32CubeF0 firmware package. Third-party toolchains including Keil MDK-ARM v4.20+, IAR EWARM v6.20.4+, Atollic TrueSTUDIO v2.1+, and TASKING VX-toolset v4.0.1+ provide full ST-LINK/V2 SWD debugging and flash programming capability.

Is the HDMI CEC functionality operational without additional hardware?

Yes-both HDMI connectors (CN3 sink and CN4 source) include full CEC and DDC circuitry with pull-up resistors and level-shifting. The STM32F051R8T6's GPIOs are preconfigured to drive CEC signals, and demonstration firmware includes CEC command transmission and reception examples using the onboard hardware.
