W78L33  
8-BIT MICROCONTROLLER  
GENERAL DESCRIPTION  
The W78L33 microcontroller supplies a wider frequency range and supply voltages than most 8-bit  
microcontrollers on the market. It is functional compatible with the industry standard 80C32  
microcontroller series except the one extra 4-bit bit-addressable I/O port (Port 4). The W78L33  
contains four 8-bit bidirectional parallel ports, three 16-bit timer/counters and a serial port. These  
peripherals are supported by a six-source, two-level interrupt capability. There are 256 bytes of RAM,  
and the device supports ROMless operation for application programs.  
The W78L33 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.
