Makers of the SXDEV Ubicom SX Embedded Controller Debugging Tool
The SX devices are totally compatible, drop in replacements for PIC 16C5x processors with emulation circuitry built in to the production device so what the ICE sees... is what the Processor saw!!! And they run at 50-75 MIPS (not just MHz, MIPS!). They are so fast, jitter-free, and deterministic, that many hardware functions can be "virtualized" into the software, reducing chip count and increaseing versatility.
The SXDEV can be powered from target board, draws less than 5 mA, 120...150 MHz, down to 3V, use any clock source (quartz, ceramic resonator, oscillator or external clock) and have advanced IDE with many features supported: for example, Timers and Bank0 support for SX48/52, data injection mode, extended watch attributes, external assembler SASM or MPASM, external simulator SxSim and external C compiler Hitech C (free version). Uses a serial port and finds it automatically. The IDE runs under Windows and is know to work under Linux using Wine.
Available from SXList.com in the US and Canada for $120 + s&h while supplies last.
