W78L51
8-BIT MICROCONTROLLER
Publication Release Date: January 1999
- 1 -
Revision A2
GENERAL DESCRIPTION
The W78L51 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 W78L51 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 W78L51 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.
