24C01

Features Low Voltage and Standard Voltage Operation – 2.7 (VCC = 2.7V to 5.5V) – 1.8 (VCC = 1.8V to 5.5V) Internally Organized 128 x 8 2-Wire Serial Interface Bidirectional Data Transfer Protocol 100 kHz (1.8V, 2.5V, 2.7V) and 400 kHz (5V) Compatibility 4-Byte Page Write Mode Self-Timed Write Cycle (10 ms max) High Reliability – Endurance: 1 Million Write Cycles – Data Retention: 100 Years Automotive Grade, Extended Temperature and Lead-Free Devices Available 8-lead PDIP, 8-lead JEDEC SOIC and 8-lead TSSOP Packages Description The AT24C01 provides 1024 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 128 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 AT24C01 is available in space saving 8-lead PDIP, 8-lead JEDEC SOIC 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. 2-Wire Serial EEPROM 1K (128 x 8) AT24C01 Pin Configurations Pin Name NC SDA SCL TEST Function No Connect Serial Data Serial Clock Input Test Input (GND or VCC) 8-lead PDIP NC NC NC GND 1 2 3 4 8 VCC 7 TEST 6 SCL 5 SDA NC NC NC GND 8-lead TSSOP 18 27 36 45 VCC TEST SCL SDA 8-lead SOIC NC NC NC GND 1 2 3 4 8 VCC 7 TEST 6 SCL 5 SDA Rev. 0134G–SEEPR–7/03 1 Absolute Maximum Ratings* Operating Temperature...
