24C01A Datasheet

2-wire Serial EEPROM


The 24C01A /02/04/08/16 provides 1024/2048/4096/8192/16384 bits of serial elec-trically 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 industrial and commercial applications where low-power and low-voltage operation are essential. The AT24C01A/02/04/08/16 is available in space-saving 8-pin PDIP, (AT24C01A/02/04/08/16), 8-lead TSSOP (AT24C01A/02/04/08/16) and 8-lead JEDEC SOIC (AT24C01A/02/04/08/16) packages and is accessed via a 2-wire serial interface. In addition, the entire family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to 5.5V), 2.5V (2.5V to 5.5V) and 1.8V (1.8V to 5.5V) versions. 24C01A Features • Low-voltage and Standard-voltage Operation – 5.0 (VCC= 4.5V to 5.5V) – 2.7 (VCC= 2.7V to 5.5V) – 2.5 (VCC= 2.5V to 5.5V) – 1.8 (VCC= 1.8V to 5.5V)• Internally Organized 128 x 8 (1K), 256 x 8 (2K), 512 x 8 (4K), 1024 x 8 (8K) or 2048 x 8 (16K)• 2-wire Serial Interface• Schmitt Trigger, Filtered Inputs for Noise Suppression• Bi-directional Data Transfer Protocol• 100 kHz (1.8V, 2.5V, 2.7V) and 400 kHz (5V) 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 (10 ms max)• High-reliability – Endurance: 1 Million Write Cycles – Data Retention: 100 Years• Automotive Grade and Extended Temperature Devices Available• 8-lead JEDEC SOIC, 8-pin PDIP and 8-lead TSSOP Packages
