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, 8-pin and 14-pin SOIC
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.
