W78C31B  
8-BIT MICROCONTROLLER  
GENERAL DESCRIPTION  
The W78C31B microcontroller supplies a wider frequency range than most 8-bit microcontrollers on  
the market. It is compatible with the industry standard 80C31 microcontroller series.  
The W78C31B contains four 8-bit bidirectional parallel ports, two 16-bit timer/counters, and a serial  
port. These peripherals are supported by a five-source, two-level interrupt capability. There are 128  
bytes of RAM, and the device supports ROMless operation for application programs.  
The W78C31B microcontroller has two power reduction modes, idle mode and power-down mode,  
both of which are software selectable. The idle mode turns off the processor clock but allows for  
continued peripheral operation. The power-down mode stops the crystal oscillator for minimum power  
consumption. The external clock can be stopped at any time and in any state without affecting the  
processor.
