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.
