Product details

Overview

STM32303E-EVAL from STMicroelectronics is an evaluation board designed to demonstrate and develop applications for the STM32F303VE microcontroller, featuring 256 KB Flash, 48 KB SRAM, and integrated analog peripherals including op-amps, comparators, and 12-bit ADCs. It supports full-featured USB 2.0 FS, CAN 2.0B, multiple timers, and hardware accelerators for math-intensive control loops.

For engineers reviewing the STM32303E-EVAL datasheet, STM32303E-EVAL pinout, STM32303E-EVAL application, or STM32303E-EVAL equivalent, this board enables rapid validation of motor control algorithms, digital power supply design, sensor fusion with capacitive touch, and real-time USB-CDC/DFU firmware updates - all using ST's STM32CubeF3 firmware stack with HAL, LL, and middleware components.

Technical Context

The board implements the STM32F303VE MCU in LQFP100 package with full external memory interface support (FSMC), dual CAN transceivers, and a dedicated ST-LINK/V2-1 debugger/programmer. It integrates on-board sensors (LSM303AGR eCompass), audio codec (CS43L22), LCD (240×320 RGB TFT), microSD slot, and Arduino™ Uno-compatible expansion headers.

It serves as a reference platform for STM32CubeF3 firmware - providing 43 level-0 HAL examples, 19 level-1 middleware applications (USB HID/MSC/CDC, FreeRTOS, FatFS, STMTouch, STemWin), and one full graphical demonstration combining all layers - all preconfigured for EWARM, MDK-ARM, TrueSTUDIO, and SW4STM32 toolchains.

FAQ

What software tools are supported for STM32303E-EVAL development?

STM32303E-EVAL is fully supported by STM32CubeMX for graphical configuration and initialization code generation, and ships with pre-configured projects for IAR Embedded Workbench (EWARM), Keil MDK-ARM, Ac6 System Workbench for STM32 (TrueSTUDIO), and SW4STM32. All examples use the STM32CubeF3 firmware package under BSD license, with HAL, LL, and middleware components validated on this board.

Does STM32303E-EVAL include a built-in debugger?

Yes - it integrates an ST-LINK/V2-1 debug probe with three functional modes: SWD/JTAG debugging, virtual COM port (VCP) for UART communication, and mass storage device (MSD) for drag-and-drop firmware programming. No external debugger is required for basic development, flashing, or serial monitoring.

Can STM32303E-EVAL run FreeRTOS and USB Device stack simultaneously?

Yes - the board runs verified STM32CubeF3 middleware examples that combine FreeRTOS with USB CDC and MSC classes, leveraging DMA-based data transfers and tickless low-power operation. The 48 KB SRAM and dual-bank Flash architecture enable concurrent real-time task scheduling and USB endpoint buffering without resource conflict.

How does STM32303E-EVAL differ from NUCLEO-F303RE?

STM32303E-EVAL uses the higher-spec STM32F303VE (100-pin LQFP, 256 KB Flash, FSMC, dual CAN, full-speed USB) versus NUCLEO-F303RE's STM32F303RE (64-pin LQFP, 512 KB Flash but no FSMC or second CAN). It adds professional-grade peripherals: RGB TFT LCD, audio codec, eCompass, microSD, and Arduino-compatible expansion - making it suited for complete HMI and control system validation.
