PRELIMINARY W78E516

8-BIT MICROCONTROLLER

GENERAL DESCRIPTION

The W78E516 is an 8-bit microcontroller which has an in-system programmable MTP-ROM for on-chip

firmware updating. The instruction set of the W78E516 is fully compatible with the standard 8052. The

W78E516 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 in the

4KB MTP-ROM; a 512 bytes of 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

six sources two-level interrupt capability. To facilitate programming and verification, the MTP-ROM

inside the W78E516 allows the program memory to be programmed and read electronically. Once the

code is confirmed, the user can protect the code for security.

The W78E516 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.

FEATURES
