• Manufacturer Part Number: IDT72V3684
• Description: 16 K X 36 X 2 Syncbififo, 3.3v
• Manufacturer: Integrated Device Technology

DESCRIPTION
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
access times as fast as 6.5ns. Two independent 16,384/32,768/65,536 x 36
dual-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.
PIN CONFIGURATION
IDT72V3684/72V3694/72V36104 3.3V CMOS SyncBiFIFO
BUS-MATCHING 16,384 x 36 x 2, 32,768 x 36 x 2 and 65, 536 x 36 x 2
The IDT72V3684/72V3694/72V36104 are designed to run off a 3.3V

employs a synchronous interface. All data transfers through a port are gated
to the LOW-to-HIGH transition of a port clock by enable signals. The clocks for
each port are independent of one another and can be asynchronous or
coincident. The enables for each port are arranged to provide a simple
bidirectional interface between microprocessors and/or buses with synchro-
nous control.
registers. The mailbox registers’ width matches the selected Port B bus width.
These devices are a synchronous (clocked) FIFO, meaning each port
Communication between each port may bypass the FIFOs via two mailbox
