ST Microelectronics: STR91xFxxx, STR91xWxxx

JTAG Debugger
ETM - Trace


Tool Features:

   Run Control (Run, Stop, Breakpoints, Single Stepping) Memory Read/Write access)
   On-chip Flash programming Support

   RTOS Support

   Support for Special Function Registers (SFRs)

The STR91xxxx family of 32-bit microcontrollers offers the best of both 16 and 32-bit worlds. It combines the industry-standard ARM966E-S® 32-bit RISC core, featuring high performance, very low power, and very dense code, with a comprehensive set of peripherals and ST's latest 0.18µ embedded Flash technology.

The STR91xxxx microcontrollers are aimed at customers who want the power and flexibility of a 32-bit microcontroller plus a rich set of on-chip peripherals. These small, highly integrated micro-controllers open the door to expanding application capabilities while driving down the total system cost.
