STMicroelectronics STR750-SK/KEIL

Overview

STR750-SK/KEIL from STMicroelectronics is a Keil™ starter kit for STR750FV2 ARM7TDMI-based microcontroller evaluation and embedded application development. It includes the µVision3 IDE, 16 KB-limited ARM RealView Compilation Tools, ULINK USB/JTAG debugger/programmer, and a full-featured evaluation board with dual USART, SPI, I²C, CAN, user LEDs (8), push buttons (3), reset, and SD/MMC connector.

For engineers reviewing the STR750-SK/KEIL datasheet, STR750-SK/KEIL pinout, STR750-SK/KEIL application, or STR750-SK/KEIL equivalent, this kit delivers validated hardware-software integration for rapid prototyping of industrial control, automotive body electronics, and CAN-based communication systems using the STR750FV2 MCU.

Technical Context

The STR750-SK/KEIL implements a complete ARM7TDMI-based development environment centered on the STR750FV2 microcontroller (64-pin LQFP, 64 MHz max, 512 KB Flash, 64 KB RAM). The board integrates ULINK's USB-to-JTAG interface for real-time debugging and flash programming via µVision3, eliminating external debug probes.

Hardware features include dual USART interfaces (one with RS-232 transceiver), two CAN channels, SPI, I²C, 8 user LEDs, 3 tactile buttons (user, wake-up, reset), SD/MMC slot, and on-board power regulation accepting 7–12 V DC input - enabling standalone operation without host USB power dependency.

FAQ

Does STR750-SK/KEIL support debugging over USB without additional hardware?

Yes. The kit includes the ULINK USB/JTAG in-circuit debugger, which connects directly to a host PC via USB and interfaces to the STR750FV2 through the onboard 20-pin JTAG header. No external debug adapter or converter is required for µVision3-based download and real-time debugging.

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

The included ARM RealView Compilation Tools license supports up to 16 KB of object code. This limitation applies only to the Keil-provided version bundled with the kit; full commercial licenses are available separately from Arm or Keil for larger applications.

Can the STR750-SK/KEIL evaluation board operate without connection to a PC?

Yes. The board accepts 7–12 V DC via its external power jack and can run independently once firmware is programmed. All peripherals - including CAN, USART, SPI, and LEDs - remain fully functional without USB host connection after initial programming and configuration.

Is the STR750FV2 microcontroller socketed or soldered on the board?

The STR750FV2 is permanently soldered in a 64-pin LQFP package on the STR750-SK/KEIL board. It is not socketed; replacement requires rework. The design prioritizes signal integrity and mechanical robustness for lab and prototype use rather than field-replaceable MCU swapping.
