Description
The AL4CE2x1 series memory products are
high-performance, low-power 9bit read/write
FIFO (First-In-First-Out) memory chip
designed to buffer high speed streaming data
for a wide range of applications. The
AL4CE2x1 FIFO memories are the advanced
version of AL4CS2x1. Retransmit is
supported in this product series to reduce
designing efforts.
