IDT72V3664 – 4,096 x 36 x 2
IDT72V3674 – 8,192 x 36 x 2
Clock frequencies up to 100 MHz (6.5ns access time)
Two independent clocked FIFOs buffering data in opposite
directions
Select IDT Standard timing (using EFA, EFB, FFA, and FFB flags
functions) or First Word Fall Through Timing (using ORA, ORB,
IRA, and IRB flag functions)
Programmable Almost-Empty and Almost-Full flags; each has five
default offsets (8, 16, 64, 256 and 1,024 )
Serial or parallel programming of partial flags
Port B bus sizing of 36 bits (long word), 18 bits (word) and 9 bits
(byte)
Big- or Little-Endian format for word and byte bus sizes
Retransmit Capability
Master Reset clears data and configures FIFO, Partial Reset
clears data but retains configuration settings
Mailbox bypass registers for each FIFO
Free-running CLKA and CLKB may be asynchronous or coincident
(simultaneous reading and writing of data on a single clock edge
is permitted)
Auto power down minimizes power dissipation
Available in space saving 128-pin Thin Quad Flatpack (TQFP)
Pin and functionally compatible version of the 5V operating
IDT723654/723664/723674

DESCRIPTION
The IDT72V3654/72V3664/72V3674 are pin and functionally compat-
ible versions of the IDT723654/723664/723674, designed to run off a 3.3V
supply for exceptionally low-power consumption. These devices are mono-
lithic, high-speed, low-power, CMOS bidirectional synchronous (clocked)
FIFO memory which supports clock frequencies up to 100 MHz and has read
accesstimesasfastas6.5ns. Twoindependent2,048/4,096/8,192 x 36dual-
port SRAM FIFOs on board each chip buffer data in opposite directions. FIFO
data on Port B can be input and output in 36-bit, 18-bit, or 9-bit formats with a
choice of Big- or Little-Endian configurations.
These devices are a synchronous (clocked) FIFO, meaning each port
employs a synchronous interface. All data transfers through a port are gated
totheLOW-to-HIGHtransitionofaportclockbyenablesignals. Theclocksfor
each port are independent of one another and can be asynchronous or
