General Description
The device is an 8-bit high performance, RISC architec-
ture microcontrollers specifically designed for opera-
tional amplifier applications. The usual Holtek
microcontroller features of low power consumption, I/O
flexibility, timer functions, oscillator options, internal
comparator, internal operational amplifiers, power down
and wake-up functions, watchdog timer and low voltage
reset, combine to provide the device with a wide range
of functional options while still maintaining a high level
of cost effectiveness. The fully integrated system oscil-
lator HIRC, which requires no external components and
which has three frequency selections, opens up a huge
range of new application possibilities for this device,
some of which may include remote control appliances,
car reversing systems, level meters, consumer prod-
ucts, household appliances subsystem controllers, etc.
