STMicroelectronics STR711-SK/IAR

Overview

STR711-SK/IAR from STMicroelectronics is an IAR Embedded Workbench®-based starter kit for the STR711FR2 ARM7TDMI-S™ microcontroller, featuring a KickStart development board, J-Link USB/JTAG debugger/programmer, and EWARM IDE with 32 KB C/C++ compiler limit-designed for rapid evaluation and firmware development of industrial control and embedded connectivity applications.

For engineers reviewing the STR711-SK/IAR datasheet, STR711-SK/IAR pinout, STR711-SK/IAR application, or STR711-SK/IAR equivalent, this kit delivers validated hardware-software integration for STR711F-series MCU peripherals including dual USARTs, SPI, I2C, CAN, USB Host, ADC with potentiometer interface, and user push-button/wake-up logic.

Technical Context

The STR711-SK/IAR provides full in-circuit debugging via J-Link's USB-to-JTAG interface and supports real-time code download and C-SPY®-driven execution analysis on the target STR711FR2 MCU. It integrates VisualSTATE® 20-state graphical design tools for state-machine-based firmware generation.

Power is supplied exclusively via the J-Link's USB connection; no external supply is required. The board includes two user LEDs, three user/tamper/wake-up buttons, reset button, and wrap area for prototyping-enabling immediate validation of interrupt handling, peripheral initialization, and low-power wake-up sequences.

FAQ

Does STR711-SK/IAR include the STR711FR2 microcontroller?

Yes. The kit contains a fully populated KickStart development board with the STR711FR2 microcontroller pre-soldered and ready for immediate use. This MCU features 64 KB Flash, 16 KB RAM, ARM7TDMI-S core, and operates up to 50 MHz with integrated CAN, USB Host, dual USARTs, SPI, I2C, and 10-bit ADC.

Is external power required to operate the STR711-SK/IAR board?

No. The board draws all operating power from the J-Link debugger's USB interface-no external power supply, wall adapter, or backup battery is needed or supported. This simplifies setup and ensures consistent voltage regulation during debug sessions.

What software tools are included with the STR711-SK/IAR kit?

The kit includes IAR Embedded Workbench for ARM (EWARM) KickStart edition: C/C++ compiler (32 KB code limit), C-SPY debugger, VisualSTATE® 20-state graphical code generator, editor, linker, librarian, built-in Flash loader, and peripheral sample projects-all pre-licensed and ready to install.

Can the STR711-SK/IAR be used to develop firmware for other STR7-series MCUs?

Yes-while optimized for the STR711FR2, the hardware and software environment supports development for compatible STR7x MCUs (e.g., STR712FR2, STR731FV2) via configuration changes in EWARM. Peripheral register mapping and startup code must be adjusted per device datasheet and reference manual.
