IDT723614 CMOS SYNCBIFIFO™ WITH BUS-MATCHING
AND BYTE SWAPPING 64 x 36 x 2
COMMERCIAL AND INDUSTRIAL
TEMPERATURE RANGES
DESCRIPTION:
The IDT723614 is a monolithic, high-speed, low-power CMOS bidirectional
clocked FIFO memory. It supports clock frequencies up to 67MHz and has read
access times as fast as 10ns. Two independent 64 x 36 dual-port SRAM FIFOs
on board the chip buffer data in opposite directions. Each FIFO has flags to
indicate empty and full conditions and two programmable flags (Almost-Full and
Almost-Empty) to indicate when a selected number of words is stored in memory.
FIFO data on port B can be input and output in 36-bit, 18-bit, and 9-bit formats
with a choice of big- or little-endian configurations. Three modes of byte-order
swapping are possible with any bus size selection. Communication between
each port can bypass the FIFOs via two 36-bit mailbox registers. Each mailbox
register has a flag to signal when new mail has been stored. Parity is checked
passively on each port and may be ignored if not desired. Parity generation
can be selected for data read from each port. Two or more devices can be used
in parallel to create wider data paths.
