General Description
The HT48R01/HT48R02/HT48R03 are 8-bit high per-
formance, RISC architecture microcontroller devices
specifically designed for I/O control.
The advantages of low power consumption, I/O flexibil-
ity, timer functions, oscillator options, Power-down and
wake-up functions, Watchdog Timer, buzzer driver, as
well as low cost, enhance the versatility of these devices
to suit a wide range of application possibilities such as
industrial control, consumer products, subsystem con-
trollers, etc.
