Emulation Solutions for TSOP and PSOP memories

Available ONLY from Grammar Engine

New embedded systems are smaller than ever, using fine pitch surface mount components. Many existing probes and cables make poor connections to these targets, so emulators no longer work reliably or provide accurate debugging information. Grammar Engine's TSOP and PSOP cables provide the best solutions available for developers testing and debugging firmware on surface mount targets. With these new cables, any TSOP and PSOP ROM or Flash can be emulated with Grammar Engine's powerful PromICE debugging tool.

These cables are available in two probe formats: socket probes and solder-down probes. The cables with socket probes are specifically designed for use with TSOP and PSOP sockets available from Meritec. These sockets have the same footprint and are only slightly larger than the memories themselves. With these sockets and Grammar Engine's cables, firmware developers can memory emulation to develop their code, and program a flash only when the code is complete. These sockets can also be used in production, allowing memory to be socketed in the embedded product until the firmware is completely stable.

By emulating memory rather than the microprocessor, the development tool needs to work only as fast as the memory access speed of the system, not the processor's clock speed. This allows the fine pitch cable connections to provide a solid, error free link for emulating memory and communicating with a monitor-based debugger. PromICE's exclusive virtual UART eliminates the need for bulky serial ports for debugging.

Additionally, TSOP cables are available with solder-down probes. These can be permanently connected directly to the memory footprint of a prototype target being used for firmware development.

All memory functions of PromICE are supported when using these cables. In addition to standard 5 volt emulation, low voltage (2.7 to 3.3 volt) emulation is supported.

All cables are in stock at Grammar Engine for immediate delivery.
