1. GENERAL DESCRIPTION
The W9725G6KB is a 256M bits DDR2 SDRAM, organized as 4,194,304 words 4 banks 16 bits. This device achieves high speed transfer rates up to 1066Mb/sec/pin (DDR2-1066) for general applications. W9725G6KB is sorted into the following speed grades: -18, -25, 25I and -3. The -18 grade parts is compliant to the DDR2-1066 (7-7-7) specification. The -25 and 25I grade parts are compliant to the DDR2-800 (5-5-5) or DDR2-800 (6-6-6) specification (the 25I industrial grade parts which is guaranteed to support -40°C ≤ TCASE ≤ 95°C). The -3 grade parts is compliant to the DDR2- 667 (5-5-5) specification. All of the control and address inputs are synchronized with a pair of externally supplied differential clocks. Inputs are latched at the cross point of differential clocks (CLK rising and CLK falling). All I/Os are synchronized with a single ended DQS or differential DQS- DQS pair in a source synchronous fashion.
2. 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.
