Product details

Overview

STR730-SK/IAR from STMicroelectronics is an IAR KickStart™ starter kit for STR73x-series ARM7TDMI-based microcontrollers, featuring a full-featured development board with STR731FV2 MCU, J-Link USB/JTAG debugger/programmer, and IAR Embedded WorkBench® for ARM (EWARM) with 32 KB KickStart compiler, C-SPY debugger, and VisualSTATE® code generator - used for rapid prototyping of industrial control and embedded connectivity applications.

For engineers reviewing the STR730-SK/IAR datasheet, STR730-SK/IAR pinout, STR730-SK/IAR application, or STR730-SK/IAR equivalent, this kit delivers validated hardware-software integration for STR73x evaluation, peripheral bring-up (USART, SPI, I²C, CAN), and real-time debugging via J-Link over USB without external power supplies.

Technical Context

The STR730-SK/IAR is a complete evaluation platform built around the STR731FV2 - a 64-pin LQFP ARM7TDMI core MCU with 256 KB Flash, 64 KB RAM, and integrated peripherals including dual USARTs, SPI, I²C, CAN 2.0B controller, 10-bit ADC, and USB 2.0 device interface. The board enables direct firmware loading and real-time trace debugging via the included J-Link probe.

Hardware features include 16 user LEDs, 5 push buttons (user/tamper/wake-up/reset), 2×16 LCD display, potentiometer connected to ADC input, SD/MMC connector, and USB host interface - all powered solely from the J-Link's USB connection, eliminating need for external power adapters during development.

FAQ

Does STR730-SK/IAR include the STR731FV2 microcontroller?

Yes. The STR730-SK/IAR contains the STR731FV2 MCU in 64-pin LQFP package, pre-mounted on the KickStart development board. This device integrates ARM7TDMI core, 256 KB Flash, 64 KB RAM, dual USART, SPI, I²C, CAN 2.0B, 10-bit ADC, and USB 2.0 device interface - confirmed in ST Doc ID 11310 Rev 8 Table 1.

Is external power required to operate the STR730-SK/IAR board?

No. The board draws all operating power (5 V and 3.3 V) directly from the J-Link debugger's USB connection to the host PC. No wall adapter, battery, or auxiliary supply is needed - verified in "Starter kit architecture" section and Table 1 of ST Doc ID 11310 Rev 8.

What software tools are included with the STR730-SK/IAR kit?

The kit includes IAR Embedded WorkBench® for ARM (EWARM) KickStart edition: C/C++ compiler (≤32 KB code output), C-SPY debugger, VisualSTATE® graphical state-machine code generator (20-state version), editor, linker, librarian, and peripheral sample projects - as specified in the "Features" and "Description" sections of ST Doc ID 11310 Rev 8.

Can the STR730-SK/IAR be used to develop CAN-based applications?

Yes. The STR731FV2 MCU on the board includes a full CAN 2.0B controller, and the board provides a dedicated CAN connector with transceiver circuitry. This enables direct CAN bus communication testing, node simulation, and protocol stack development - explicitly listed under "Table 1. KickStart development board key features" for STR731-SK/IAR in ST Doc ID 11310 Rev 8.
