W9725G6KB25I General Description
The W9725G6KB25I DDR2 SDRAM module from Winbond Electronics is a high-capacity memory solution, with a capacity of 1GB and a maximum clock frequency of 400MHz. Operating at a supply voltage of 1.8V, this module offers reliable and efficient performance for memory-intensive computing tasks. Its 60-ball BGA package makes it suitable for space-constrained designs in desktop computers, laptops, servers, and industrial applications, providing high-speed data transfer capabilities and versatility
Key Features
- Power Supply: VDD, VDDQ = 1.8 V ± 0.1V
- 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 compliant
