General Description
The Enhanced I/O MCUs are a series of 8-bit high per-
formance, RISC architecture microcontrollers specifi-
cally designed for a wide range of applications. The
usual Holtek microcontroller features of low power con-
sumption, I/O flexibility, timer functions, oscillator op-
tions, 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 main-
taining a high level of cost effectiveness. The fully inte-
grated 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 in-
clude industrial control, consumer products, household
appliances subsystem controllers, etc.
