General Description

The Enhanced A/D MCU devices are a series of 8-bit high performance, RISC architecture 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, 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 the device, some of which may include industrial control, consumer products, household appliances subsystem controllers, etc.
