Description
The AT24C01A/02/04/08/16 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/02/04/08/16 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.
