STMicroelectronics STR71X-SK/RAIS

Overview

STR71X-SK/RAIS from STMicroelectronics is a REva starter kit for STR71xF ARM7TDMI™-based microcontrollers, featuring an interchangeable daughterboard with STR712F or STR711F MCU, embedded RLink JTAG debugger/programmer, USB-powered REva motherboard, and Raisonance RIDE7 IDE with GNU C compiler and simulator. It supports CAN, USB, ADC, I²C, SPI, USART, and on-board analog/digital I/O evaluation.

For engineers reviewing the STR71X-SK/RAIS datasheet, STR71X-SK/RAIS pinout, STR71X-SK/RAIS application, or STR71X-SK/RAIS equivalent, this kit delivers full in-circuit debugging up to 64 KB debug code, unlimited Flash programming, SO-DIMM-based daughterboard modularity, and native support for STR71xF boot mode and CAN configuration via jumpers - critical for industrial control and legacy ARM7 migration projects.

Technical Context

The STR71X-SK/RAIS implements a modular evaluation architecture centered on the REva universal motherboard, which hosts interchangeable SO-DIMM daughterboards. Its embedded RLink provides USB-to-JTAG bridging with 20-pin ARM standard interface and supports trace-capable debugging when used with STR9 devices (though STR71xF lacks ETM).

Hardware evaluation features include dual USARTs, CAN transceiver with configurable termination, potentiometer-fed ADC input, temperature sensor, eight user LEDs, two push buttons, reset button, prototyping area, and selectable VDD (1.8V/3.3V/5V). Daughterboard-specific capabilities - such as USB mini-B connector on STR711F and CAN configuration jumpers on STR712F - are physically implemented and documented in Table 2 of Doc ID 11543 Rev 8.

Key Specifications

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, designing and manufacturing microcontrollers, power ICs, sensors, and analog/mixed-signal products for industrial, automotive, and consumer markets.

The STR7 family was engineered for cost-sensitive, real-time industrial applications requiring deterministic interrupt response, integrated CAN, and low-power ARM7TDMI™ execution - targeting programmable logic controllers, motor drives, and building automation systems.

FAQ

Does STR71X-SK/RAIS include the STR71xF microcontroller?

Yes - the kit includes a pre-mounted STR712F or STR711F daughterboard (as specified in ordering codes STR71X-SK/RAIS and Table 2), with full Flash memory, SRAM, and peripheral integration verified per ST's STR71xF reference design. No additional MCU purchase is required to begin development.

What software tools ship with STR71X-SK/RAIS?

The kit ships with Raisonance RIDE7 IDE, GNU C compiler, high-level language debugger, SIMICE simulator, and RFlasher programming utility. All tools are licensed for unlimited use with the embedded RLink debugger and support STR71xF-specific startup files, linker scripts, and peripheral drivers.

Can STR71X-SK/RAIS be used with other STR7 daughterboards?

Yes - the REva motherboard uses a standard SO-DIMM connector compatible with all STR7-D/RAIS daughterboards (e.g., STR750-D/RAIS, STR730-D/RAIS). Mechanical and electrical pinout alignment is guaranteed per ST's REva specification, enabling cross-family evaluation without hardware modification.

Is USB host connectivity required for debugging?

Yes - the embedded RLink debugger requires a USB 2.0 connection to a Windows host PC running RIDE7. No external power supply, JTAG adapter, or additional cables are needed; USB provides both power and bidirectional debug communication at full speed.
