1. GENERAL DESCRIPTION
The W78L32 microcontroller supplies a wider frequency range and supply voltages than most 8-bit
microcontrollers on the market. It is compatible with the industry standard 80C32 microcontroller
series.
The W78L32 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 W78L32 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.
