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

industrial and commercial applications where low-power and low-voltage operation

are essential. The AT24C01A/02/04/08A/16A is available in space-saving 8-lead PDIP,

8-lead JEDEC SOIC, 8-lead MAP, 5-lead SOT23 (AT24C01A/AT24C02/AT24C04), 8-

lead TSSOP, and 8-ball dBGA2 packages and is accessed via a Two-wire serial inter-

face. In addition, the entire family is available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to

5.5V) versions.
