The device’scascadable feature allows up to 4 devices to share a common 2-wire bus. The deviceis optimized for use in many industrial and commercial applications where low-powerand low-voltage operation are essential. The devices are available in space-saving8-pin PDIP, 8-lead EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead LeadlessArray (LAP) and 8-ball dBGA packages. In addition, the entire family is available in2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions.Rev. 1116J– SEEPR– 7/032-wire Serial EEPROM512K (65,536 x 8)AT24C512 Pin ConfigurationsPin NameFunctionA0 - A1Address InputsSDASerial DataSCLSerial Clock InputWPWrite ProtectNCNo Connect8-lead PDIP 12348765A0A1NCGNDVCCWPSCLSDA8-lead Leadless Array Bottom View12348765VCCWPSCLSDAA0A1NCGND8-lead TSSOP 12348765A0A1NCGNDVCCWPSCLSDA8-ball dBGA Bottom ViewVCCWPSCLSDAA0A1NCGND123487658-lead SOIC 12348765A0A1...
