2-WORD BURST OPERATION

August 2, 2011

Description

The μPD44324092B is a 4,194,304-word by 9-bit, the μPD44324182B is a 2,097,152-word by 18-bit and the

μPD44324362B is a 1,048,576-word by 36-bit synchronous double data rate static RAM fabricated with

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

The μPD44324092B, μPD44324182B and μPD44324362B 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

• Two-tick burst for low DDR transaction size

• 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 20 μs after clock is resumed.

• User programmable impedance output (35 to 70 Ω)

• Fast clock cycle time : 3.3 ns (300 MHz), 3.5ns (287MHz), 4.0 ns (250 MHz), 5.0 ns (200 MHz)

• Simple control logic for easy depth expansion

• JTAG 1149.1 compatible test access port
