STMicroelectronics STR750-SK/IAR

Overview

STR750-SK/IAR from STMicroelectronics is an IAR KickStart™ starter kit for ARM7TDMI-based STR750FV2 microcontroller evaluation and embedded application development. It includes the full-featured KickStart development board, J-Link in-circuit debugger/programmer (USB/JTAG), and IAR Embedded WorkBench® for ARM (EWARM) with 32 KB KickStart C/C++ compiler, C-SPY® debugger, VisualSTATE® 20-state code generator, and peripheral sample projects.

For engineers reviewing the STR750-SK/IAR datasheet, STR750-SK/IAR pinout, STR750-SK/IAR application, or STR750-SK/IAR equivalent, this kit delivers immediate hardware/software co-validation capability for STR750FV2-based designs requiring CAN, USB Host, SPI, I²C, USART, ADC, LCD, and SD/MMC interface support.

Technical Context

The STR750-SK/IAR provides a complete out-of-box environment for developing firmware on the STR750FV2 - a 64 MHz ARM7TDMI-S core MCU with 512 KB Flash, 64 KB SRAM, and integrated peripherals including dual CAN 2.0B controllers, USB 2.0 Full-Speed host controller, 3×USART, 2×SPI, I²C, 10-bit ADC, and LCD controller.

Hardware integration centers on the J-Link debugger's seamless EWARM coupling, enabling real-time flash programming and source-level debugging via 20-pin JTAG, while the board draws power solely from the host PC's USB connection and supports user interaction via 16 LEDs, 5 push buttons (user/tamper/wake-up/reset), and a 2×16 character LCD display.

FAQ

Does STR750-SK/IAR support programming the STR750FV2's internal Flash memory?

Yes. The included J-Link in-circuit debugger/programmer fully supports Flash programming of the STR750FV2 via its 20-pin JTAG interface. IAR EWARM's built-in Flash loader enables direct download and erase/write operations without external hardware, verified in official ST application notes and IAR documentation for this kit.

Can the STR750-SK/IAR be used with IDEs other than IAR EWARM?

No - the STR750-SK/IAR is licensed exclusively for use with IAR Embedded WorkBench for ARM (EWARM) KickStart edition. While the J-Link hardware may support other tools via OpenOCD or Segger software, the kit's bundled license, preloaded firmware, and sample projects are validated only for EWARM and not compatible with Keil MDK or GCC-based toolchains.

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

The included IAR EWARM KickStart edition supports compilation of up to 32 KB of executable code. This limit applies to the final linked output image - not source lines or object files - and is enforced by the compiler license embedded in the software distribution provided with the STR750-SK/IAR kit.

Is external power required to operate the STR750-SK/IAR board?

No. The board is powered entirely through the USB connection from the host PC to the J-Link debugger. There is no provision for external DC input or backup battery - power management is handled internally, and all peripherals (LCD, LEDs, USB, CAN transceivers) operate within the USB 5 V / 500 mA specification.
