General Description

The EC24C128A/EC24C256A provides 131,072 /262,144 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as16,384/32,768 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 EC24C128A/EC24C256A is available in space-saving PDIP-8,SOP-8, MSOP-8 and TSSOP-8 packages and is accessed via a twowire serial interface.
