Accutek Microcircuit Corporation DESCRIPTION The Accutek AK5361024BW high density memory module is a CMOS dynamic RAM organized in 1024K x 36 bit words. The module consists of two standard 1 Meg x 16 bits DRAMs and one 1 Meg x 4 bit Quad CAS DRAM in plastic SOJ packages. The assembly has 3 DRAMs mounted on the front 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 AK5361024BW is identical to eight 1 Meg x 4 plus four 1 Meg x 1 DRAMs. There are four CAS lines and two RAS lines. Independent byte control is accomplished by four CAS lines. Each seperate CAS line controls one byte of the 1 Meg x 16 plus a parity bit in the QUAD CAS DRAM. 1 AK5361024BW 1,048,576 Word by 36 Bit CMOS Dynamic Random Access Memory 72 FEATURES 1,048,576 x 36 bit organization 72 pad Single In-Line Module Standard with gold fingers, solder or tin plating optional 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: 2.125 Watt Max Active (50nS) 1.975 Watt Max Active (60 nS) 1.825 Watt Max Active (70 nS) 30 mW Max Standby Downward compatible with AK536512W and AK536256W Upward compatible with AK5362048W, AK5364096W and AK5368192W ADDITIONAL OPTIONS AVAILABLE 1 ……
