Preliminary W78C51D

8-BIT MICROCONTROLLER

GENERAL DESCRIPTION

The W78C51D microcontroller supplies a wider frequency and supply voltage range than most 8-bit

microcontrollers on the market. It is compatible with the industry standard 80C51 microcontroller

series.

The W78C51D contains four 8-bit bidirectional parallel ports, one extra 4-bit bit-addressable I/O port

(Port 4) and two additional external interrupts (INT2 , INT3 ), two 16-bit timer/counters, one watchdog

timer and a serial port. These peripherals are supported by a seven-source, two-level interrupt

capability. There are 128 bytes of RAM and an 4K byte mask ROM for application programs.

The W78C51D 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.
