W971GG6KB-25I - Brand New Winbond Electronics Memory
-
Description
The W971GG6KB-25I is a 1G bits DDR2 SDRAM, organized as 8,388,608 words ✔ 8 banks ✔ 16 bits. It achieves high speed transfer rates up to 1066Mb/sec/pin (DDR2-1066) for various applications. This model is available in different grade parts such as -18, -25, 25I, and -3. The -18 grade parts are compliant with the DDR2-1066 (7-7-7) specification. The -25 and 25I grade parts are compliant with the DDR2-800 (5-5-5) or DDR2-800 (6-6-6) specification. The 25I industrial grade is guaranteed to support -40°C ≤ TCASE ≤ 95°C. The -3 grade parts are compliant with the DDR2-667 (5-5-5) specification. The device has synchronized control and address inputs with externally supplied differential clocks, and all I/Os are synchronized with a single-ended DQS or differential DQS- DQS pair in a source synchronous fashion.
Specifications and Features
Power Supply: VDD, VDDQ = 1.8 V ± 0.1 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 84 Ball (8X12.5 mm2), using Lead free materials with RoHS compliantApplication Scenarios
