TEL: 886-3-6668838 FAX: 886-3-6668836 0 ® LY62L6416 Rev. 1.2 64K X 16 BIT LOW POWER CMOS SRAM GENERAL DESCRIPTION The LY62L6416 is a 1,048,576-bit low power CMOS static random access memory organized as 65,536 words by 16 bits. It is fabricated using very high performance, high reliability CMOS technology. Its standby current is stable within the range of operating temperature. The LY62L6416 is well designed for low power application, and particularly well suited for battery back-up nonvolatile memory application. The LY62L6416 operates from a single power supply of 2.7V ~ 3.6V and all inputs and outputs are fully TTL compatible FEATURES „ Fast access time : 45/55/70ns „ Low power consumption: Operating current : 23/20/18mA (TYP.) Standby current : 1μA (TYP.) LL/SL -version „ Single 2.7V ~ 3.6V power supply „ All inputs and outputs TTL compatible „ Fully static operation „ Tri-state output „ Data byte control : LB# (DQ0 ~ DQ7) UB# (DQ8 ~ DQ15) „ Data retention voltage : 1.5V (MIN.) „ Green package available „ Package : 44-pin 400 mil TSOP-II 48-ball 6mm x 8mm TFBGA PRODUCT FAMILY Product Family LY62L6416 LY62L6416(E) LY62L6416(I) Operating Temperature 0 ~ 70℃ -20 ~ 80℃ -40 ~ 85℃ Vcc Range 2.7 ~ 3.6V 2.7 ~ 3.6V 2.7 ~ 3.6V Speed 45/55/70ns 45/55/70ns 45/55/70ns Power Dissipation Standby(ISB1,TYP.)
