PRELIMINARY DATA SHEET

MOS INTEGRATED CIRCUIT

μPD44644084, 44644094, 44644184, 44644364

72M-BIT DDR II SRAM

4-WORD BURST OPERATION

Description

The μPD44644084 is a 8,388,608-word by 8-bit, the μPD44644094 is a 8,388,608-word by 9-bit, the μPD44644184 is a

4,194,304-word by 18-bit and the μPD44644364 is a 2,097,152-word by 36-bit synchronous double data rate static RAM

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

The μPD44644084, μPD44644094, μPD44644184 and μPD44644364 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

• Pipelined double data rate operation

• Common data input/output bus

• 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
