  • Winbond W9751G6KB-25

    W9751G6KB-25 8M 4 BANKS 16BIT DDR2 SDRAM

    The W9751G6KB 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 1066Mb/sec/pin (DDR2-1066) for various applications. W9751G6KB is sorted into the following speed grades: -18, -25, 25I, 25A, 25K and -3.The -18 is compliant to the DDR2-1066 (7-7-7) specification. The -25, 25I, 25A and 25K 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 -3 is compliant to the DDR2-667 (5-5-5) specification.

    Winbond W9825G6KH-6I 4 M  4 BANKS  16 BITS SDRAM

    GENERAL DESCRIPTIONW9825G6KH is a high-speed synchronous dynamic random access memory (SDRAM), organized as  4M words  4 banks  16 bits. W9825G6KH delivers a data bandwidth of up to 200M words per  second. To fully comply with the personal computer industrial standard, W9825G6KH is sorted into the  following speed grades: -5, -5I, -6, -6I, -6J, -6L, -75, 75J and 75L.The -5/-5I grade parts are compliant to the 200MHz/CL3 specification (the -5I industrial grade which is  guaranteed to support -40°C ≤ TA ≤ 85°C).The -6/-6I/-6J/-6L grade parts are compliant to the 166MHz/CL3 specification (the -6I industrial grade  which is guaranteed to support -40°C ≤ TA ≤ 85°C, the -6J industrial plus grade which is guaranteed to  support -40°C ≤ TA ≤ 105°C).The -75/75J/75L grade parts are compliant to the 133MHz/CL3 specification (the 75J industrial plus  grade which is guaranteed to support -40°C ≤ TA ≤ 105°C).The -6L and 75L grade parts support self refresh current IDD6 max. 1.5 mA.  Accesses to the SDRAM are burst oriented. Consecutive memory location in one page can be  accessed at a burst length of 1, 2, 4, 8 or full page when a bank and row is selected by an ACTIVE  command. Column addresses are automatically generated by the SDRAM internal counter in burst  operation. Random column read is also possible by providing its address at each clock cycle. The  multiple bank nature enables interleaving among internal banks to hide the precharging time.By having a programmable Mode Register, the system can change burst length, latency cycle,  interleave or sequential burst to maximize its performance. W9825G6KH is ideal for main memory in  high performance applications.2.
