Description
The W9725G8JB is a 256M bits DDR2 SDRAM, organized as 8,388,608 words x 4 banks x 8 bits. This device achieves high speed transfer rates up to 1066Mb/sec/pin (DDR2-1066) for general applications. It is compliant with DDR2-1066 (7-7-7), DDR2-800 (5-5-5 or 6-6-6), and DDR2-667 (5-5-5) specifications. The industrial grade (25I) supports a wide temperature range of -40°C to 95°C.
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
