STMicroelectronics STM3210B-SK/IAR

Overview

STM3210B-SK/IAR from STMicroelectronics is an IAR Embedded Workbench®-based starter kit for STM32F103RB ARM Cortex-M3 microcontrollers, featuring a full-featured KickStart development board, J-Link USB/JTAG in-circuit debugger/programmer, and EWARM KickStart edition (32 KB code limit), used for rapid prototyping of motor control and industrial HMI applications.

For engineers reviewing the STM3210B-SK/IAR datasheet, STM3210B-SK/IAR pinout, STM3210B-SK/IAR application, or STM3210B-SK/IAR equivalent, this kit delivers integrated toolchain support, on-board peripherals including USART, SPI, I²C, CAN, USB, and LCD interface, and direct compatibility with IAR's C-SPY debugger and VisualSTATE® state-machine generator.

Technical Context

The STM3210B-SK/IAR provides a complete evaluation environment centered on the STM32F103RB (LQFP64, 72 MHz Cortex-M3) with 128 KB Flash and 20 KB RAM. It integrates hardware debug via J-Link (USB-to-JTAG), enabling real-time debugging, flash programming, and trace-free execution monitoring.

Board-level features include dual USART interfaces, one CAN transceiver, full-speed USB 2.0 device port, 2×16-character LCD module, 16 user LEDs, 3 push buttons (user/tamper/reset), ADC-connected potentiometer, and SD/MMC card slot - all powered directly from the host PC's USB connection.

FAQ

Does STM3210B-SK/IAR support SWD debugging?

Yes - the included J-Link debugger supports both JTAG and Serial Wire Debug (SWD) protocols. The board uses a standard 20-pin JTAG header compatible with SWD signaling, allowing full debug access to the STM32F103RB's Cortex-M3 core without requiring additional adapters or pin remapping.

Is the 32 KB code limit in EWARM KickStart enforceable at compile time?

Yes - the IAR EWARM KickStart license strictly enforces the 32 KB output code size limit during linking. If generated object code exceeds this threshold, the linker returns error "Error[e11]: Cannot fit section .text into memory region RAM" or similar, preventing binary generation until code is optimized or trimmed.

Can the on-board LCD be used with STM32 standard peripheral library (StdPeriph) drivers?

Yes - the 2×16 character HD44780-compatible LCD is directly supported by ST's legacy StdPeriph Library examples included in the kit's sample project suite. GPIO initialization, 4-bit data mode timing, and busy-flag polling are preconfigured for immediate use with minimal modification.

Does STM3210B-SK/IAR include a built-in ST-LINK programmer?

No - this kit uses IAR's J-Link hardware exclusively. It does not contain ST-LINK circuitry. Programming and debugging rely solely on the bundled J-Link unit via USB, and no ST-LINK firmware or virtual COM port functionality is present on the board.
