Features

? 1.8 ± 0.1 V power supply

? 165-pin PLASTIC BGA (13 x 15)

? HSTL interface

? PLL circuitry for wide output data valid window and future frequency scaling

? Separate independent read and write data ports with concurrent transactions

? 100 bus utilization DDR READ and WRITE operation

? Four-tick burst for reduced address frequency

? Two input clocks (K and K#) for precise DDR timing at clock rising edges only

? Two output clocks (C and C#) for precise flight time

and clock skew matching-clock and data delivered together to receiving device

? Internally self-timed write control

? Clock-stop capability. Normal operation is restored in 1,024 cycles after clock is resumed.

? User programmable impedance output

? Fast clock cycle time : 3.7 ns (270 MHz), 4.0 ns (250 MHz), 5.0 ns (200 MHz)

? Simple control logic for easy depth expansion

? JTAG boundary scan

? Operating ambient temperature: Commercial TA = 0 to +70°C (-E37, -E40, -E50)

Industrial TA = –40 to +85°C (-E40Y, -E50Y)
