1.0 Description
The AL4CS211/AL4CS221/AL4CS231/AL4CS241/AL4CS251 series memory products are high-
performance, low-power 9-bit read/write FIFO (First-In-First-Out) memory chips. They are
specially designed to buffer high speed streaming data for a wide range of communication
applications, such as optical disk controllers, Local Area Networks (LANs), SONET (Synchronous
Optical Network).
The input data is synchronous with a free-running clock (WCLK), and input-enable pins (/WEN1,
/WEN2). Data is written into the FIFO on every clock when enable pins are asserted. The output is
synchronous with the other free-running clock (RCLK) and enables (/REN1, /REN2). An Output
Enable pin (/OE) is provided at the read port for tri-state control of the output port. The FIFOs can
output two fixed flags, Empty Flag( /EF) and Full Flag (/FF), and two programmable flags, Almost-
Empty (/PAE) and Almost-Full (/PAF). The offsets of the /PAE and /PAF flags are loaded when
Load pin (/LD) goes low.
