• Big-Endian/Little-Endian user selectable byte representation

• Auto power down minimizes standby power consumption

• Master Reset clears entire FIFO

• Partial Reset clears data, but retains programmable settings

• Empty, Full and Half-Full flags signal FIFO status

• Up to 225 MHz Operation of Clocks

• User selectable HSTL/LVTTL Input and/or Output

• 2.5V LVTTL or 1.8V, 1.5V HSTL Port Selectable Input/Ouput voltage • Select IDT Standard timing (using EF and FF flags) or First Word

• 3.3V Input tolerant Fall Through timing (using OR and IR flags)

• Read Enable & Read Clock Echo outputs aid high speed operation • Output enable puts data outputs into high impedance state

• User selectable Asynchronous read and/or write port timing

• Mark & Retransmit, resets read pointer to user marked position

• Write Chip Select (WCS) input enables/disables Write operations

• Read Chip Select (RCS) synchronous to RCLK

• JTAG port, provided for Boundary Scan function

• Available in 208-pin (17mm x 17mm) or 240-pin (19mm x 19mm)

Plastic Ball Grid Array (PBGA)

• Easily expandable in depth and width

• Programmable Almost-Empty and Almost-Full flags, each flag can • Independent Read and Write Clocks (permit reading and writing

default to one of eight preselected offsets

simultaneously)

• Program programmable flags by either serial or parallel means

• Selectable synchronous/asynchronous timing modes for Almost-

• High-performance submicron CMOS technology

• Industrial temperature range (–40°C to +85°C) is available
