Plastic Ball Grid array (PBGA), 219

balls, 1.27mm pitch.

Four internal banks for concurrent

operation

Impedance matched (60ohm) pack-

2.5V ±0.2V Core Power supply

aging

One data mask per byte, IMOD con-

tains (10) bytes

2.5V ±0.2V I/O Power supply

(SSTL_2 compatible)

High TCE organic laminate inter-

poser

Programmable IOL/IOH Option

Auto PRECHARGE option

Differential Clock inputs (CLKx,

CLKx\)

Suitable for High Reliability applica-

tions

Commands entered on each positive

CLKx edge

Auto REFRESH and SELF

REFRESH Modes

Internal pipelined double-data-

rate (DDR) Architecture; two data

accesses per clock cycle

Available in INDUSTRIAL,

EXTENDED and Mil-Temp ranges

Organized as 16M x 72/80

Programmable Burst Length:

2, 4, or 8

Weight: LOGIC Devices, Inc.

L9D125G80BG4 = 2.75 grams

Bidirectional data strobe (DQSLx,

DQsHx) per byte transmitted/

received with data

typical

i.e. source-synchronous data capture
