Description

The HM-6642 is a 512 x 8 CMOS NiCr fusible link

Programmable Read Only Memory in the popular 24 pin,

byte wide pinout. Synchronous circuit design techniques

combine with CMOS processing to give this device high

speed performance with very low power dissipation.

On-chip address latches are provided, allowing easy

interfacing with recent generation microprocessors that use

multiplexed address/data bus structures, such as the 8085.

The output enable controls, both active low and active high,

further simplify microprocessor system interfacing by

allowing output data bus control independent of the chip

enable control. The data output latches allow the use of the

HM-6642 in high speed pipelined architecture systems, and

also in synchronous logic replacement functions.

Applications for the HM-6642 CMOS PROM include low

power handheld microprocessor based instrumentation and

communications systems, remote data acquisition and

processing systems, processor control store, and synchro-

nous logic replacement.

All bits are manufactured storing a logical “0” and can be

selectively programmed for a logical “1” at any bit location.
