W9751G6NB-25原装 DDR2

W9751G6NB-25原装 DDR2 的描述：

The W9751G6NB is a 512M bits DDR2 SDRAM, organized as 8,388,608 words ′ 4 banks ′ 16 bits. This device achieves high speed transfer rates up to 1066 Mbps (DDR2-1066) for various applications.

W9751G6NB is sorted into the following speed grades: -18, -25, -3, 18I, 25I, -3I, 18J, 25J and -3J. The -18, 18I and 18J grade parts are compliant to the DDR2-1066 (7-7-7) specification (the 18I industrial grade which is guaranteed to support -40°C ≤ TCASE ≤ 95°C, the 18J industrial plus grade which is guaranteed to support -40°C ≤ TCASE ≤ 105°C).

The -25, 25I and 25J grade parts are compliant to the DDR2-800 (5-5-5) or DDR2-800 (6-6-6) specification (the 25I industrial grade which is guaranteed to support -40°C ≤ TCASE ≤ 95°C, the 25J industrial plus grade which is guaranteed to support -40°C ≤ TCASE ≤ 105°C). The -3, -3I and -3J grade parts are compliant to the DDR2-667 (5-5-5) specification (the -3I industrial grade which is guaranteed to support -40°C ≤ TCASE ≤ 95°C, the -3J industrial plus grade which is guaranteed to support -40°C ≤ TCASE ≤ 105°C).

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
