General Description

The device is an 8-bit high performance, RISC architec-

ture microcontroller devices specifically designed for

multiple I/O control product applications. The low volt-

age operating requirements of these devices opens up

new application possibilities.

The advantages of low power consumption, I/O flexibil-

ity, timer functions, oscillator options, Power-down

wake-up functions, Watchdog timer, motor driving, in-

dustrial control, consumer products, subsystem control-

lers, etc.
