Revision A4
1. GENERAL DESCRIPTION
The W78E054C is an 8-bit microcontroller which can accommodate a wider frequency range with low
power consumption. The instruction set for the W78E054C is fully compatible with the standard 8051.
The W78E054C contains an 16K bytes Flash EPROM; a 256 bytes RAM; four 8-bit bi-directional and
bit-addressable I/O ports; an additional 4-bit I/O port P4; three 16-bit timer/counters; a hardware
watchdog timer and a serial port. These peripherals are supported by eight sources two-level interrupt
capability. To facilitate programming and verification, the Flash EPROM inside the W78E054C allows
the program memory to be programmed and read electronically. Once the code is confirmed, the user
can protect the code for security.
The W78E054C 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.
