General Description
The HT48R01A is 8-bit high performance, RISC archi-
tecture microcontroller specifically designed for a wide
range of applications. The usual Holtek microcontroller
features of low power consumption, I/O flexibility, timer
functions, oscillator options, power down and wake-up
functions, watchdog timer and low voltage reset, com-
bine to provide devices with a huge range of functional
options while still maintaining cost effectiveness. Their
fully integrated system oscillator, with three frequency
selections, and being supplied in an extremely small
outline MSOP 10-pin package opens up a huge range of
new application possibilities for these devices, some of
which may include industrial control, consumer prod-
ucts, household appliances subsystem controllers, etc.
