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 Ultra Thin Mini-MAP (MLP 2x3), 5-lead SOT23 (AT24C01A/AT24C02/AT24C04), 8-lead TSSOP, and 8-ball dBGA2 packages and is accessed via a Two-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.
