AT24C64AN Datasheet



The AT24C64AN provides 32,768/65,536 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 4096/8192 words of 8 bitseach. The device’s cascadable feature allows up to 8 devices to share a common twowire bus. The device is optimized for use in many industrial and commercial applicationswhere low power and low voltage operation are essential. The AT24C64AN is available in space saving 8-lead JEDEC PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead Mini-MAP (MLP 2x3) and 8-lead TSSOP packages and is accessed via a 2-wire serial interface. In addition, the entire family is available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 5.5V) versions. AT24C64AN Features• Low-Voltage and Standard-Voltage Operation– 2.7 (VCC = 2.7V to 5.5V)– 1.8 (VCC = 1.8V to 5.5V)• Low-Power Devices (ISB = 6 μA @ 5.5V) Available• Internally Organized 4096 x 8, 8192 x 8• Two-wire Serial Interface• Schmitt Trigger, Filtered Inputs for Noise Suppression• Bidirectional Data Transfer Protocol• 400 kHz (1.8V, 2.5V, 2.7V, 5V) Compatibility• Write Protect Pin for Hardware Data Protection• 32-byte Page Write Mode (Partial Page Writes Allowed)• Self-timed Write Cycle (5 ms Max)• High Reliability– Endurance: 1 Million Write Cycles– Data Retention: 100 Years• Automotive Devices Available• 8-lead JEDEC PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead Mini-MAP (MLP 2x3) and 8-lead TSSOP Packages• Lead-free/Halogen-free• Die Sales: Wafer Form, Waffle Pack, and Bumped Wafers
