Preliminary W78IE54
8-BIT MTP MICROCONTROLLER
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.
