General Description

The HT48E30 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.
