General Description
The device is a fully static part fabricated using double-met-
al silicon gate microCMOS technology Features include an
8-bit memory mapped architecture MICROWIRE PLUS
serial I O three 16-bit timer counters supporting three
modes (Processor Independent PWM generation External
Event counter and Input Capture mode capabilities) full du-
plex UART and two comparators Each I O pin has software
selectable configurations The devices operates over a volt-
age range of 2 7V to 5 5V High throughput is achieved with
an efficient regular instruction set operating at a maximum
rate of 1 s per instruction
