AT24C512 Datasheet

2-wire Serial EEPROM


The AT24C512 provides 524,288 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 65,536 words of 8 bits each. The device’s cascadable feature allows up to 4 devices to share a common 2-wire bus. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The devices are available in space-saving 8-pin PDIP, 20-pin JEDEC SOIC, 8-pin Leadless Array (LAP), and 8-ball dBGA packages. In addition, the entire family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions. AT24C512 Features • Low-voltage and Standard-voltage Operation – 5.0 (VCC = 4.5V to 5.5V) – 2.7 (VCC = 2.7V to 5.5V) – 1.8 (VCC = 1.8V to 3.6V)• Internally Organized 65,536 x 8• 2-wire Serial Interface• Schmitt Triggers, Filtered Inputs for Noise Suppression• Bidirectional Data Transfer Protocol• 1 MHz (5V), 400 kHz (2.7V) and 100 kHz (1.8V) Compatibility• Write Protect Pin for Hardware and Software Data Protection• 128-byte Page Write Mode (Partial Page Writes Allowed)• Self-timed Write Cycle (5 ms Typical)• High Reliability – Endurance: 100,000 Write Cycles – Data Retention: 40 Years – ESD Protection: >4000V• Automotive Grade and Extended Temperature Devices Available• 8-pin PDIP and 20-pin JEDEC SOIC, 8-pin LAP, and 8-ball dBGA Packages
