8-BIT MICROCONTROLLER
GENERAL DESCRIPTION
The W78L54 microcontroller supplies a wider frequency and supply voltage range than most 8-bit
microcontrollers on the market. It is compatible with the industry standard 80C54 microcontroller
series. The W78L54 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 ), three 16-bit timer/counters, one
watchdog timer and a serial port. These peripherals are supported by a eight-source, two-level
interrupt capability. There are 256 bytes of RAM and an 16K byte mask ROM for application
programs.
The W78L54 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.
