General Description
The device is an 8-bit high performance, RISC architec-
ture microcontroller devices specifically designed for
multiple I/O, mouse/keyboard appliances and SPI con-
trol product applications. The advantages of low power
consumption, I/O flexibility, Timer functions, Watchdog
timer, Power Down, wake-up functions together with the
optional peripherals such as EEPROM Memory and RF
transceiver provide the devices with versatility for indus-
trial control, consumer products, subsystem controllers,
RF module control, etc.
