Accutek Microcircuit Corporation DESCRIPTION The Accutek AK5322048BW high density memory module is a CMOS dynamic RAM organized in 2048K x 32 bit words. The module consists of four standard 1 Meg x 16 bits DRAMs in plastic SOJ packages. The assembly has two DRAMs mounted on each side of a printed circuit board in a 72 pad leadless SIM configuration. This configuration allows socket-mounting of large quantities of memory in applications where high density and ease of inserting additional memory are important. The operation of the AK5322048BW is identical to sixteen 1 Meg x 4 DRAMs. There are four CAS lines and two RAS lines. On each bank of 1M x 32, independent byte control is accomplished by four CAS lines. Each seperate CAS line controls one byte of the 1 Meg x 16 DRAM. + AK5322048BW 2,097,152 Word by 32 Bit CMOS Dynamic Random Access Memory + FEATURES 2,097,152 x 32 bit organization 72 pad Single In-Line Module CAS-before-RAS, RAS-only or hidden refresh Operating free air temperature 0oC to 70oC Single 5 Volt Power Supply 1024 Refresh Cycles, 16 mSEC Available in Fast Page Mode or EDO Power: 3.96 Watt Max Active (50nS) 3.52 Watt Max Active (60 nS) 3.08 Watt Max Active (70 nS) 44 mW Max Standby Downward compatible with AK5321024W, AK532512W and AK532256W Upward compatible with AK5324096W and AK5328192W ADDITIONAL OPTIONS AVAILABLE 1 Meg x 32 version, AK5321024BW 1 Meg x 36 version, AK5361024BW 2 Meg x 36 version, AK5362048BW PIN NOMENCLATURE A0 - A9 DQ0 - DQ3……
