Applications

Description

The AL4CE2x5 series memory products are

high-performance, low-power 18bit read/write

FIFO (First-In-First-Out) memory chip designed

to buffer high speed streaming data for a wide

range of applications. The AL4CE2x5 FIFO

memories

AL4CS2x5.

additional functions, such as Bus-matching,

Endian select and Retransmit, can benefit

designing efforts.
