5V) Clock Rate • Write Protect Pin for Hardware and Software Data Protection • 256-byte Page Write Mode (Partial Page Writes Allowed) • Random and Sequential Read Modes • Self-timed Write Cycle (5 ms Typical) • High Reliability – Endurance: 1,000,000 Write Cycles/Page – Data Retention: 40 Years • 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead TSSOP, 8-lead Ultra Thin Small Array (SAP), and 8-ball dBGA2 Packages • Die Sales: Wafer Form, Tape and Reel and Bumped Die Description The AT24C1024B provides 1,048,576 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 131,072 words of 8 bits each.
The device’s cascadable feature allows up to four devices to share a common two-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-lead PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead TSSOP, 8-ball dBGA2 and 8-lead Ultra Thin SAP packages.
In addition, the entire family is available in 1.
8V (1.
8V to 3.
6V) and 2.
5V (2.
5V to 5.
5V) versions.
