FUNCTIONAL DESCRIPTION

The LH5496/96H are dual port memories with internal

addressing to implement a First-In, First-Out algorithm.

Through an advanced dual port architecture, they provide

fully asynchronous read/write operation. Empty, Full, and

Half-Full status flags are provided to prevent data over-

flow and underflow. In addition, internal logic provides for

unlimited expansion in both word size and depth.

Read and write operations automatically access se-

quential locations in memory in that data is read out in the

same order that it was written, that is on a First-In,

First-Out basis. Since the address sequence is internally

predefined, no external address information is required

for the operation of this device. A ninth data bit is provided

for parity or control information often needed in commu-

nication applications.

Empty, Full, and Half-Full status flags monitor the

extent to which data has been written into the FIFO, and

prevent improper operations (i.e., Read if the FIFO is

empty, or Write if the FIFO is full). A retransmit feature

resets the Read address pointer to its initial position,

thereby allowing repetitive readout of the same data.

Expansion In and Expansion Out pins implement an

expansion scheme that allows individual FIFOs to be

cascaded to greater depth without incurring additional

latency (bubblethrough) delays.
