General Description
The HT48E70 is an 8-bit high performance, RISC archi-
tecture 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.
