HT48R064G/065G/066G/0662G -- Enhanced I/O Type
8-bit MCU with OPA (Enhanced OTP MCU)
General Description
The Enhanced I/O 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.
