EC24C1024A-2-Wire Serial EEPROM

General Description

EC24C1024A provides wide voltage of 1,048,576 bits of serial electrically erasable and programmable read-only

memory (EEPROM) organized as 131,072 words of 8 bits each.      The device can be connected in series to achieve

the characteristics of the four devices to share a two-wire system addressable bus. The device is optimized for use in

many industrial and commercial applications where low-power and low-voltage operations are essential.
