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

remote controllers, fan/light controllers, wash-

ing machine controllers, scales, toys and vari-

ous subsystem controllers. A HALT feature is

included to reduce power consumption.
