64Mx64 DDR2 SDRAM w/ SHARED CONTROL BUS

iNTEGRATED Plastic Encapsulated Microcircuit

BENEFITS

FEATURES

DDR2 Data rate = 667, 533, 400

58% Space Savings

Available in Industrial, Enhanced and Extended Temp

Package:

49% I/O reduction vs Individual CSP approach

Reduced part count

• Proprietary Enchanced Die Stacked iPEM

• 208 Plastic Ball Grid Array (PBGA), 16 x 23mm

• 1.00mm ball pitch

Reduced trace lengths for lower parasitic

capacitance

Suitable for hi-reliability applications

Upgradable to 128M x 64 density in future

Differential data strobe (DQS, DQS#) per byte

Internal, pipelined, double data rate architecture

4n-bit prefetch architecture

DLL for alignment of DQ and DQS transitions with

clock signal

Eightinternal banks for concurrent operation

(Per DDR2 SDRAM Die)

Programmable Burst lengths: 4 or 8

Auto Refresh and Self Refresh Modes (I/T Version)

On Die Termination (ODT)

Adjustable data – output drive strength

1.8V 0.1V common core power and I/O supply

Programmable CAS latency: 3, 4, 5, 6 or 7

Posted CAS additive latency: 0, 1, 2, 3, 4 or 5

Write latency = Read latency - 1* tCK

Organized as 64M x 64

Weight: AS4DDR264M64PBG1 ~ 2.0 grams typical

NOTE: Self Refresh Mode available on Industrial and Enhanced temp. only
