The Lauterbach LA-7699 and LA-7742 are specialized debug modules for embedded systems development. The LA-7699 Power Debug II Ethernet serves as a universal debug controller with a 500 MHz PowerPC core and high-speed FPGA, delivering 1000 DMIPS of performance. The LA-7742 is a dedicated JTAG debugger targeting ARM9 processors across 0.4 V to 5 V operating ranges. Both modules enable real-time tracing, high-level and assembly-language debugging, and flash programming of internal and external memory. They support multiprocessor and multicore system debugging with full compiler compatibility.

– Compatibility & Integration
The LA-7742 requires a Power Debug Module—such as USB 2.0, Ethernet, PowerTrace, Power Debug II, or PowerDebug PRO—to access cJTAG and SWD functionality. Both products interface with all major compiler toolchains and support mixed-language debugging environments. The IDC20A cable uses standard polarized connectors (Tyco/T&B 1-1658526-3 / 609-2041).
