General Description
The device is an 8-bit high performance
RISC-like microcontroller designed for multi-
ple I/O product applications. The device is par-
ticularly suitable for use in products such as
battery charger controllers and A/D applica-
tions. A HALT feature is included to reduce
power consumption.
The program and option memories can be elec-
trically programmed, making the microcontrol-
ler suitable for use in product development.
