DESCRIPTION:
The IDT723613 is a monolithic, high-speed, low-power, CMOS synchro-
nous (clocked) FIFO memory which supports clock frequencies up to 67 MHz
and has read-access times as fast as 10 ns. The 64 x 36 dual-port SRAMFIFO
buffers data fromport A to port B. The FIFO has flags to indicate empty and full
conditions, and two programmable flags, Almost-Full (
AF
) and Almost-Empty
(
AE
), to indicate when a selected number of words is stored in memory. FIFO
data on port B can be 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 FIFO via two 36-bit mailbox registers. Each mailbox register has
a flag to signal when new mail has been stored. Parity is checked passively
