Description
The AL4CX263/AL4CX273/AL4CX283/
AL4CX293 FIFO (First In First Out) memory
provides completely independent 18bit bus
width input and output port operation with
flexible x18/ x9 Bus-Matching data flow
control at a maximum speed of 166 Mhz. The
products are available in densities from
128Kbit to 1Mbit. Additional features of the
AL4CX2x3 series include: fixed and
programmable flags; low first word latency;
partial reset; Endian select; expandable
depth/width.
The embedded memory array with built-in
address decoder, pointer manager and state-
