General Description
The HT46R01/HT46R02/HT46R03 are 8-bit high per-
formance, RISC architecture microcontroller devices
specifically designed for a wide range of applications. In
addition to providing the usual microcontroller I/O con-
trol functions, the fully integrated A/D converter allows
the interfacing and processing of external analog sig-
nals such as those from sensors. The PWM function
also allows the driving of external analog signals for ap-
plications such as motor driving while the PFD function
provides a means of generating a fixed frequency refer-
ence. The usual Holtek microcontroller features of low
power consumption, I/O flexibility, timer functions, oscil-
lator options, power down and wake-up functions,
watchdog timer and low voltage reset, combine to pro-
vide devices with a huge range of functional options
while still maintaining cost effectiveness. Their fully inte-
grated system oscillator, with three frequency selec-
tions, 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 include may include industrial control, consumer
products, household appliances subsystem controllers,
etc.
