GENERAL DESCRIPTION
The W78L054A is an 8-bit microcontroller which can accommodate a wide supply voltage range with low power consumption. The instruction set for the W78L054A is fully compatible with the standard 8051. The W78L054A 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 W78L054A allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security.
