Description

The AT24C01A/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-Pin MSOP (AT24001A/02), 8-Pin TSSOP

(AT24C01A/02/04/08/16), and 8-Pin and 14-Pin 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.
