W9816G6IH-6集成电路（IC）的存储器规格书PDF中文资料

GENERAL DESCRIPTION

W9816G6IH is a high-speed synchronous dynamic random access memory (SDRAM), organized as 512K words × 2 banks × 16 bits. W9816G6IH delivers a data bandwidth of up to 200M words per second (-5). For different applications the W9816G6IH is sorted into the following speed grades: -5/-6/-7/-6I and -7I. The -5 parts can run up to 200MHz/CL3 or 143MHz/CL2. The -6/-6I parts can run up to 166MHz/CL3 (the -6I grade which is guaranteed to support -40°C ~ 85°C). The -7/-7I parts can run up to 143MHz/CL3 (the -7I grade which is guaranteed to support -40°C ~ 85°C).
