Revision A7
1. GENERAL DESCRIPTION
The W78L516 is an 8-bit microcontroller which has an in-system programmable Flash EPROM for
firmware updating. The instruction set of the W78L516 is fully compatible with the standard 8052. The
W78L516 contains a 64K bytes of main Flash EPROM and a 4K bytes of auxiliary Flash EPROM
which allows the contents of the 64KB main Flash EPROM to be updated by the loader program
located at the 4KB auxiliary Flash EPROM; 512 bytes of on-chip RAM; four 8-bit bi-directional and bit-
addressable I/O ports; an additional 4-bit port P4; three 16-bit timer/counters; a serial port. These
peripherals are supported by a eight sources two-level interrupt capability. To facilitate programming
and verification, the Flash EPROM inside the W78L516 allows the program memory to be
programmed and read electronically. Once the code is confirmed, the user can protect the code for
security.
The W78L516 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.
