EDD5108AFTA

DATA SHEET 512M bits DDR SDRAM EDD5108AFTA (64M words × 8 bits) EDD5116AFTA (32M words × 16 bits) Description The EDD5108AFTA and the EDD5116AFTA are 512M bits Double Data Rate (DDR) SDRAM organized as 16,777,216 words × 8 bits × 4 banks and 8,388,608 words × 16 bits × 4 banks, respectively. Read and write operations are performed at the cross points of the CK and the /CK. This high-speed data transfer is realized by the 2 bits prefetch-pipelined architecture. Data strobe (DQS) both for read and write are available for high speed and reliable data bus design. By setting extended mode register, the on-chip Delay Locked Loop (DLL) can be set enable or disable. It is packaged in standard 66-pin plastic TSOP (II).
