Product details

Overview

STM32303C-EVAL from STMicroelectronics is an evaluation board built around the STM32F303VC microcontroller - an Arm® Cortex®-M4 MCU with FPU, 256 KB Flash, 48 KB SRAM, 4 ADCs, 2 DACs, and integrated analog peripherals including 7 comparators and 4 operational amplifiers. It supports full-speed USB, CAN 2.0B, multiple I²C/SPI/USART interfaces, and capacitive touch sensing - used for rapid prototyping of motor control, analog signal processing, and industrial HMI applications.

For engineers reviewing the STM32303C-EVAL datasheet, STM32303C-EVAL pinout, STM32303C-EVAL application, or STM32303C-EVAL equivalent, this page provides verified hardware architecture, on-board peripheral mappings (including ST-LINK/V2-1 debugger, MEMS sensors, audio codec, and LCD), real-world power supply configurations, and validated firmware compatibility with STM32CubeF3.

Technical Context

The board implements a complete reference design for the STM32F303VC LQFP100 MCU, featuring dual-bank Flash for seamless firmware updates, CCM-SRAM for time-critical code execution, and dedicated analog domain routing (VDDA/VSSA isolation) to support simultaneous high-resolution ADC sampling and PGA-based signal conditioning. All analog supplies (2.4–3.6 V for DAC/OPAMP, 2–3.6 V for ADC/COMP) are independently filtered and decoupled per datasheet layout guidelines.

It integrates ST's standardized evaluation platform architecture: ST-LINK/V2-1 debug interface with SWD/JTAG, onboard 3-axis accelerometer (LIS302DL), audio subsystem (CS43L22 codec + mono speaker), 320×240 RGB LCD with capacitive touch controller, and expansion headers matching Arduino UNO R3 and ST Morpho pinouts - enabling direct connection to motor drivers, industrial I/O modules, and sensor daughterboards.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, designing and manufacturing microcontrollers, power ICs, sensors, and analog/mixed-signal devices for industrial, automotive, and consumer markets.

The STM32303C-EVAL belongs to ST's STM32 Evaluation Board product line - engineered to accelerate firmware development, hardware validation, and system-level integration for the STM32F3 series' mixed-signal capabilities, especially in analog-intensive applications like precision measurement and closed-loop motor control.

FAQ

Does STM32303C-EVAL support ST-Link firmware updates?

Yes - the embedded ST-LINK/V2-1 interface supports firmware upgrades via ST's official STSW-LINK007 utility. The bootloader is pre-flashed and accessible through the SWD port; no external programmer is required for updating ST-LINK firmware or loading user applications.

Can the on-board LCD be replaced with a different display?

Yes - the ILI9341-based 320×240 RGB TFT uses a standard 16-bit parallel interface with dedicated CS/RS/WR/RD control lines. Replacement displays must match the same timing, voltage (3.3 V logic), and command set; ST provides full initialization code and driver examples in STM32CubeF3 HAL libraries.

Is the LIS302DL accelerometer calibrated at factory?

No - the LIS302DL is supplied uncalibrated. ST provides offset/gain calibration routines in the STM32F303xC firmware package (STM32CubeF3), and the evaluation board's schematics include test points for analog output verification and manual trim adjustment if needed.

What USB classes does the on-board CS43L22 audio codec support?

The CS43L22 operates as an I²S slave device driven by the STM32F303VC's audio PLL and SPI/I²S peripheral - not as a USB audio class device. Audio streaming is handled over I²S; USB connectivity on the board is reserved exclusively for ST-LINK/V2-1 debugging and virtual COM port (VCP) functions.
