HT46R016/HT46R017
Enhanced A/D Type 8-Bit OTP MCU
General Description
The Enhanced A/D MCUs are a series of 8-bit high performance, RISC architecture microcontrollers
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 these devices, some of which
may include industrial control, consumer products, household appliances subsystem controllers, etc.
