General Description
The HT48F70E is an 8-bit high performance, RISC ar-
chitecture microcontroller device specifically designed
for multiple I/O control product applications.
The advantages of low power consumption, I/O flexibil-
ity, timer functions, oscillator options, HALT 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.
