PRELIMINARY DATA SHEET

MOS INTEGRATED CIRCUIT

PD44645084, 44645094, 44645184, 44645364

72M-BIT QDR^TMII SRAM

4-WORD BURST OPERATION

Description

The μPD44645084 is a 8,388,608-word by 8-bit, the μPD44645094 is a 8,388,608-word by 9-bit, the μPD44645184 is a

4,194,304-word by 18-bit and the μPD44645364 is a 2,097,152-word by 36-bit synchronous quad data rate static RAM

fabricated with advanced CMOS technology using full CMOS six-transistor memory cell.

The μPD44645084, μPD44645094, μPD44645184 and μPD44645364 integrate unique synchronous peripheral

circuitry and a burst counter. All input registers controlled by an input clock pair (K and K#) are latched on the positive

edge of K and K#.

These products are suitable for application which require synchronous operation, high speed, low voltage, high density

and wide bit configuration.

These products are packaged in 165-pin PLASTIC BGA.

Features

• 1.8 ± 0.1 V power supply

• 165-pin PLASTIC BGA (15 x 17)

• 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
