Preliminary W78IE54
8-BIT MTP MICROCONTROLLER
Publication Release Date: August 1999

Revision A1
GENERAL DESCRIPTION
The W78IE54 is an 8-bit microcontroller which can accommodate a wide supply voltage range with
low power consumption. The W78IE54 can operate normally within the temperature of industrial
standard range from –40 to 85
°
C. The instruction set for the W78IE54 is fully compatible with the
standard 8051. The W78IE54 contains an 16K bytes MTP ROM (Multiple-Time Programmable ROM);
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 MTP-ROM inside the W78IE54 allows the program memory to be programmed and read
electronically. Once the code is confirmed, the user can protect the code for security.
The W78IE54 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.
