HT46R064D/065D/066D
Enhanced A/D Type 8-Bit OTP MCU with LED Driver
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. In addition, these devices
provide high driving ability I/O pins to drive the LED Array directly, which can be used in various
LED display applications. 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.
