8-BIT MICROCONTROLLER
Publication Release Date: February 2000

Revision A3
GENERAL DESCRIPTION
The W78E516B is an 8-bit microcontroller which has an in-system programmable MTP-ROM for
firmware updating. The instruction set of the W78E516B is fully compatible with the standard 8052.
The W78E516B contains a 64K bytes of main MTP-ROM and a 4K bytes of auxiliary MTP-ROM
which allows the contents of the 64KB main MTP-ROM to be updated by the loader program located
at the 4KB auxiliary MTP-ROM; 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 MTP-ROM inside the W78E516B allows the program memory to be programmed
and read electronically. Once the code is confirmed, the user can protect the code for security.
The W78E516B 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.
