GENERAL DESCRIPTION

The W78L801 is an 8-bit microcontroller which can accommodate a wide range of supply voltages with low power consumption. The instruction set for the W78L801 is fully compatible with the standard 8051. The W78L801 contains an 4K bytes Mask ROM; a 256 bytes RAM; four 8-bit bi-directional and bit-addressable I/O ports; an additional 6-bit I/O port P4; two 16-bit timer/counters; a hardware watchdog timer. These peripherals are supported by a twelve sources two-level interrupt capability. The W78L801 does not contain serial port.
