com 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.
FEATURES • 8-bit CMOS microcontroller • Fully static design • L...
