IX, Science-Based Industrial Park, Hsinchu 300, Taiwan. TEL: 886-3-6668838 FAX: 886-3-6668836 1 ® FEATURES Fast access time : 55/70ns Low power consumption: Operating current : 45/30mA (TYP.) Standby current : 10 μA (TYP.) LL-version 4 μA (TYP.) SL-version Single 2.7V ~ 3.6V power supply All inputs and outputs TTL compatible Fully static operation Tri-state output Data retention voltage : 1.2V (MIN.) Green package available Package : 44-pin 400 mil TSOP-II 48-ball 6mm x 8mm TFBGA GENERAL DESCRIPTION The LY62L20488 is a 16,777,216-bit low power CMOS static random access memory organized as 2,097,152 words by 8 bits. It is fabricated using very high performance, high reliability CMOS technology. Its standby current is stable within the range of operating temperature. The LY62L20488 is well designed for very low power system applications, and particularly well suited for battery back-up nonvolatile memory application. The LY62L20488 operates from a single power supply of 2.7V ~ 3.6V and all inputs and outputs are fully TTL compatible PRODUCT FAMILY Product Family Operating Temperature Vcc Range Speed Power Dissipation Standby(ISB1,TYP.)
