HT46R064G/065G/0662G
Enhanced A/D Type 8-Bit OTP MCU with OPA
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.
