• Up to 250MHz Operation of Clocks

-4ns read/write cycle time, 3.2ns access time

• Users selectable input port to output port data rates, 500Mb/s

Data Rate

• Partial Reset clears data, but retains programmable settings

• Empty and Full flags signal FIFO status

• Select IDT Standard timing (using EF and FF flags) or First

Word Fall Through timing (using OR and IR flags)

• Output enable puts data outputs into High-Impedance state

• JTAG port, provided for Boundary Scan function

• 208 Ball Grid array (PBGA), 17mm x 17mm, 1mm pitch

• Easily expandable in depth and width

• Independent Read and Write Clocks (permit reading and writing

simultaneously)

-DDR to DDR

-DDR to SDR

-SDR to DDR

-SDR to SDR

• User selectable HSTL or LVTTL I/Os

• Read Enable & Read Clock Echo outputs aid high speed operation

• 2.5V LVTTL or 1.8V, 1.5V HSTL Port Selectable Input/Ouput voltage

• 3.3V Input tolerant

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

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

Operations

• High-performance submicron CMOS technology

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

• Read Chip Select (RCS) synchronous to RCLK

• Programmable Almost-Empty and Almost-Full flags, each flag
