W971GG8JB-25 +BOM

Product W971GG8JB-25 is manufactured by Winbond Electronics Corporation

SDRAM - DDR2 Memory IC 1Gbit Parallel 200 MHz 57.5 ns 60-WBGA (8x12.5)

Power Supply: VDD, VDDQ = 1.8 V0.1 V

Double Data Rate architecture: two data transfers per clock cycle

CAS Latency: 3, 4, 5, 6 and 7

Burst Length: 4 and 8

Bi-directional, differential data strobes (DQS and DQS ) are transmitted / received with data

Edge-aligned with Read data and center-aligned with Write data

DLL aligns DQ and DQS transitions with clock

Differential clock inputs (CLK and CLK )

Data masks (DM) for write data.

Commands entered on each positive CLK edge, data and data mask are referenced to both edges of DQS

Posted CAS programmable additive latency supported to make command and data bus efficiency

Read Latency = Additive Latency plus CAS Latency (RL = AL + CL)

Off-Chip-Driver impedance adjustment (OCD) and On-Die-Termination (ODT) for better signal quality

Auto-precharge operation for read and write bursts

Auto Refresh and Self Refresh modes

Precharged Power Down and Active Power Down

Write Data Mask

Write Latency = Read Latency - 1 (WL = RL - 1)

Interface: SSTL_18

Packaged in WBGA 60 Ball (8x12.5 mm2), using Lead free materials with RoHS compliant
