General Description
The HT48RA0-5 is 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, watchdog timer, HALT and wake-up
functions, as well as low cost, enhance the versatility of
this device to suit a wide range of application possibili-
ties such as industrial control, consumer products, and
particularly suitable for use in products such as infrared
remote controllers and various subsystem controllers.
