Accutek AK63264 SRAM Module consists fast high performance SRAMs mounted profile, Board. module utilizes four SRAMs packages four decoupling capacitors each side printed circuit board. SRAMs used have common functions single output enable functions. Also, four separate chip select (CE) connections used independently enable four bytes. modules supplied variety access time values from nSEC nSEC CMOS BiCMOS technology. Accutek module designed have maximum seated height 0.600 inch 0.500 inch provide lowest height board. offset-mounting back surface SRAMs version module mounted either angled straight-up sockets. Each conforms JEDEC standard sizes pin-out configurations. Using pins module memory density identification, PD1, minimizes interchangeability design considerations when changing from module size other customer applications.
