General Description  
The device is an 8-bit high performance, RISC architec-  
ture microcontroller devices specifically designed for  
multiple I/O control product applications. With its inter-  
nal 27MHz amplifier the device is suitable for applica-  
tions such as 27MHz or 2.4GHz keypads etc.  
The advantages of low power consumption, I/O flexibil-  
ity, timer functions, oscillator options, Power Down and  
wake-up functions, Watchdog timer, motor driving, in-  
dustrial control, consumer products, subsystem control-  
lers, etc.
