EEPROM
Features • Standard-voltage Operation – 2.7 (VCC = 2.7V to 5.5V) • Automotive Temperature Range –40°C to 125°C • Internally Organized 128 x 8 (1K), 256 x 8 (2K), 512 x 8 (4K), 1024 x 8 (8K) or 2048 x 8 (16K) • Two-wire Serial Interface • Schmitt Trigger, Filtered Inputs for Noise Suppression • Bidirectional Data Transfer Protocol • 400 kHz Compatibility • Write Protect Pin for Hardware Data Protection • 8-byte Page (1K, 2K), 16-byte Page (4K, 8K, 16K) Write Modes • Partial Page Writes are Allowed • Self-timed Write Cycle (5 ms max) • High-reliability – Endurance: 1 Million Write Cycles – Data Retention: 100 Years • 8-lead JEDEC SOIC and 8-lead TSSOP Packages Description The AT24C01A/02/04/08A/16A provides 1024/2048/4096/8192/16384 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 128/256/512/1024/2048 words of 8 bits each. The device is optimized for use in many automotive applications where low-power and low-voltage operation are essential. The AT24C01A/02/04/08A/16A is available in space-saving 8-lead JEDEC SOIC and 8-lead TSSOP packages and is accessed via a two-wire serial interface. In addition, the entire family is available in 2.7V (2.7V to 5.5V) versions. Table 1.
