General Description
The HT45R36 is an 8-bit high performance, RISC archi-
tecture microcontroller device specifically designed for
cost-effective multiple I/O control product applications.
The advantages of low power consumption, I/O flexibil-
ity, timer functions, oscillator options, Power Down and
wake-up functions, Watchdog Timer, enhance the ver-
satility of these devices to suit a wide range of applica-
tion possibilities such as industrial control, consumer
products, subsystem controllers, etc.
