NOVEMBER 2007January 2007 AS6C8016 512KX 8 BIT LOW POWER CMOS SRAM 512K X 16 BIT SUPER LOW POWER CMOS SRAM FEATURES GENERAL DESCRIPTION The AS6C8016 is a 8,388,608-bit low power Fast access time : 55ns CMOS static random access memory organized as Low power consumption: 524,288 words by 16 bits. It is fabricated using very Operating current : 30mA (TYP.) high performance, high reliability CMOS technology. Standby current : 6A (TYP.) LL-version Its standby current is stable within the range of Single 2.7V ~ 5.5V power supply operating temperature. All inputs and outputs TTL compatible Fully static operation The AS6C8016 is well designed for low power Tri-state output application, and particularly well suited for battery Data byte control : LB (DQ0 ~ DQ7) back-up nonvolatile memory application. UB (DQ8 ~ DQ15) Data retention voltage : 1.5V (MIN.) The AS6C8016 operates from a single power Lead free and green package available supply of 2.7V ~ 5.5V and all inputs and outputs are Package : 44-pin 400 mil TSOP-II fully TTL compatible 48-ball 6mm x 8mm TFBGA PRODUCT FAMILY Product Operating Power Dissipation Vcc Range Speed Family Temperature Standby(ISB1,TYP.)
