THE M8051W AND M8051EW

THE M8051W AND M8051EW ARE HIGH PERFORMANCE CORES THAT EXCECUTE EACH MACHINE CYCLE IN TWO CLOCK CYCLES, GIVING A CLOCK-FOR-CLOCK PERFORMANCE THAT IS SIX TIMES FASTER THAN THE M8051 AND M8052 CORES. THEY REMAIN HOWEVER BINARY AND MEMORY CYCLE COMPATIBLE WITH INTEL MCS-51 DEVICES.

The M8051W and M8051EW incorporate various extended features, such as extra data pointers, support of extra interrupts and interrupt priority levels, optional multiple clock domains for optimising power consumption and support for synchronous memory cells.

The M8051EW includes a rich hardware debugger a JTAG debug port that supports external debugger environments. Hardware breakpoints, instruction traceback and full read/write access to all registers and memories are supported. We recommend the FS2 System Navigator debug system, for which the M8051EW on-chip instrumentation was originally designed.
