W78LE812 8-BIT MTP MICROCONTROLLER
GENERAL DESCRIPTION
The W78LE812 is an 8-bit microcontroller which can accommodate a wide range of supply
voltages with low power consumption.
The instruction set for the W78LE812 is fully compatible with the standard 8051.
The W78LE812 contains an 8K bytes MTP ROM (Multiple-Time Programmable ROM); a 256 bytes RAM; four 8-bit bi-directional and bit-addressable I/O ports; an additional 6-bit I/O port P4; three 16-bit timer/counters; a hardware watchdog timer and a serial port.
These peripherals are supported by a fourteen sources two-level interrupt capability.
To facilitate programming and verification, the MTP-ROM inside the W78LE812 allows the program mem...
