STX-RLINK
Raisonance’s in-circuit debugger/programmer
for ST7, uPSD, STR7 and STR9
The RLink (STX-RLINK) is Raisonance’s
versatile, low-cost, in-circuit debugger and
programmer for ST7, uPSD, STR7 and STR9
microcontrollers. It connects to application or
evaluation boards for in-circuit programming and
debugging via an industry standard JTAG
connection for ARM® core-based and uPSD
microcontrollers, or via STMicroelectronic’s In-
Circuit Communication (ICC) connection for ST7
microcontrollers.
RLink driven by Raisonance’s RIDE integrated
development environment provides both in-circuit
debugging and programming of applications for
ST7 and uPSD, and in-circuit programming of
STR7/9 microcontrollers. In combination with
Raisonance’s free RFlasher programming
software, RLink can be used as a very-low cost,
dedicated in-circuit programmer for ST7, uPSD or
STR7/9.

Architecture
RLink – Raisonance’s in-circuit debugging and
programming tool supports both JTAG and ICC
protocols and connects to your application board
via one of three adapters:
■ 10-pin ICC adapter for ST7 microcontrollers
■ 14-pin JTAG adapter for uPSD microcontrollers
■ 20-pin JTAG adapter for STR7 and STR9
microcontrollers
RIDE – Raisonance’s integrated development
environment drives the RLink and offers seamless
control of software development tools (compiler,
assembler, linker, debugger, etc.) from an intuitive
graphical interface. It offers full integration of the
relevant C/C++ toolsets, project management,
code editor and SIMICE instruction set simulator.
The optional Code Compressor, the post link code
optimizer is available for both ST7 and uPSD.

Note: RLinks included with REva starter kits for
STR7/9 (STRxxx-SK/RAIS from ST) and
Professional Kits for STR7/9 (STXPRO/
RAIS from ST) allow debugging of
both STR7 and STR9 microcontrollers

Note: The RLink does not include trace support for ARM core-based devices with Embedded
Trace Macrocell™ such as STR9. Tools with trace capability are available in the STR9
Professional Developer Kit from Raisonance (STR9-DK/RAIS) with Signum JTAGjet, and in
the STR91x Advanced Developer’s Kit from IAR (STR91X-DK/RAIS) with J-Trace.
