W78C154  
8-BIT MICROCONTROLLER  
GENERAL DESCRIPTION  
The W78C154 is an single-chip 8-bit microcontroller that is functionally compatible with the standard  
80C52 microcontroller series. Like the W78C52, the W78C154 has the following features (except that  
it has 16K bytes of on-chip ROM, and P1.6 and P1.7 are open-drain output. See Page 12 Application  
Note.) 256 bytes of on-chip scratchpad RAM, four 8-bit bidirectional parallel ports, three 16-bit  
timer/counters, one full duplex serial port, a six-source two-level interrupt structure, an on-chip  
oscillator and clock circuitry.  
The W78C154 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.
