W971GG8JB-18 - Brand New Winbond Electronics IC Chips
-
Description
The W971GG8JB-18 is a 1G bits DDR2 SDRAM, organized as 16,777,216 words x 8 banks x 8 bits. This device achieves high speed transfer rates up to 1066Mb/sec/pin (DDR2-1066) for general applications. It belongs to the IC Chips category and is available in various speed grades: -18, -25, 25I, 25A, 25K, and -3. The -18 model is compliant to the DDR2-1066 (6-6-6) specification. The -25/25I models are compliant to the DDR2-800 (5-5-5) specification, with the 25I industrial grade supporting -40°C ≤ TCASE ≤ 95°C. The -3 model is compliant to the DDR2-667 (5-5-5) specification.
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 60 Ball (8x12.5 mm2), using Lead free materials with RoHS compliant
Application Scenarios
