General Description
The 48R065V is a 24V VFD Type 8-bit high perfor-
mance, RISC architecture microcontrollers specifically
designed for a wide range of applications. The usual
Holtek microcontroller features of low power consump-
tion, I/O flexibility, timer functions, oscillator options,
power down and wake-up functions, watchdog timer
and low voltage reset, combine to provide devices with
a huge range of functional options while still maintaining
a high level of cost effectiveness. The fully integrated
system oscillator HIRC, which requires no external
components and which has three frequency selections,
opens up a huge range of new application possibilities
for these devices, some of which may include industrial
control, consumer products, household appliances sub-
system controllers, etc.
