Description
The AL4CX3650/ 3660/ 3670/ 3680/ 3690
FIFO (First In First Out) memory provides
completely independent 36-bit bus width
input and output port operation with flexible
x36/ x18/ x9 Bus-Matching data flow
control at a maximum speed of 166 MHz.
The products are available in densities from
64K-bit to 1M-bit with word depths from
2K to 32K bit. Additional features of the
AL4CX36x0 series include: fixed and
programmable flags; low first word latency;
partial reset; Endian select; expandable
depth/width and optional first-word-fall-
through. The AL4CX36x0 FIFO memory is
AverLogic Technologies, latest products that
is designed to buffer high-speed data for a
wide range of application such as optical
storage controllers, Networking Switches
and various communication applications.
