STMicroelectronics STM3210E-SK/KEIL

Overview

STM3210E-SK/KEIL from STMicroelectronics is a Keil-branded starter kit for STM32F103E microcontrollers (ARM Cortex-M3 core, 512 KB Flash, 64 KB RAM), featuring ULINK USB/JTAG debugger, µVision3 IDE, ARM RealView Compilation Tools (16 KB code limit), and a full-featured evaluation board with USART, SPI, I²C, CAN, USB Micro-B, SD/MMC, joystick, potentiometer, motion sensor, and 8 user LEDs.

For engineers reviewing the STM3210E-SK/KEIL datasheet, STM3210E-SK/KEIL pinout, STM3210E-SK/KEIL application, or STM3210E-SK/KEIL equivalent, this kit supports rapid prototyping of industrial control, motor drive, and connectivity-focused embedded applications using ST's performance-line STM32F103E MCU with Ethernet-ready peripheral set.

Technical Context

The STM3210E-SK/KEIL integrates hardware and software into a single development environment: the on-board STM32F103EVC6 microcontroller runs at 72 MHz, includes 512 KB Flash and 64 KB SRAM, and exposes all major peripherals-including dual CAN, USB Device, 10/100 Ethernet MAC (with external PHY footprint), and FSMC interface-via accessible headers and connectors.

ULINK debugger provides JTAG/SWD debugging over USB with real-time trace support via 20-pin trace connector; µVision3 IDE enables seamless build-debug-deploy workflow with RTX real-time kernel integration, while the 16 KB code-limited RVCT compiler supports C/C++ development targeting Cortex-M3 instruction set architecture.

FAQ

Does STM3210E-SK/KEIL include an Ethernet PHY chip?

No. The board includes the STM32F103E's integrated 10/100 Ethernet MAC controller and provides a footprint for an external PHY (e.g., DP83848), but no PHY is populated. Users must add and configure a compatible PHY to enable full Ethernet functionality.

What is the maximum code size supported by the included compiler?

The included ARM RealView Compilation Tools (RVCT) is a 16 KB code-size limited version. Applications exceeding 16 KB of compiled object code will not link unless upgraded to a licensed full-version compiler or replaced with GCC-based toolchains like Arm GNU Toolchain.

Is the ULINK debugger compatible with modern Windows versions?

Yes - ULINK firmware and Keil µVision3 v4.x (and later) support Windows 10 and Windows 11 when used with Keil's official drivers and updated ULINK firmware (v2.0+). Legacy XP-era drivers require manual compatibility mode configuration.

Can the STM32F103EVC6 on this board be replaced with another STM32 variant?

No - the board is designed specifically for the LQFP100-packaged STM32F103EVC6. Pin-compatible replacements (e.g., STM32F103ZET6) are not supported due to differences in peripheral mapping, voltage requirements, and footprint alignment on the evaluation board layout.
