JANUARY 2008January 2007 AS6C8008 512KX 8 BIT LOW POWER CMOS SRAM 1024K X 8 BIT SUPER LOW POWER CMOS SRAM FEATURES GENERAL DESCRIPTION The AS6C8008 is a 8,388,608-bit low power Fast access time : 55ns CMOS static random access memory organized as Low power consumption: 1,048,576 words by 8 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 AS6C8008 is well designed for very low Tri-state output power system applications, and particularly well Data retention voltage : 1.5V (MIN.) suited for battery back-up nonvolatile memory Lead free and green package available application. Package : 44-pin 400 mil TSOP-II 48-ball 6mm x 8mm TFBGA The AS6C8008 operates from a single power supply of 2.7V ~ 5.5V and all inputs and outputs are fully TTL compatible PRODUCT FAMILY Product Operating Power Dissipation Vcc Range Speed Family Temperature Standby(ISB1,TYP.)
