Description

The ACE24AC16C is 16,384 bits of serial Electrical Erasable and Programmable Read Only Memory,

commonly known as EEPROM. They are organized as 2,048 words of 8 bits (1 byte) each. The devices

are fabricated with proprietary advanced CMOS process for low power and low voltage applications.

These devices are available in standard 8-lead DIP, 8-lead SOP, 8-lead MSOP, 8-lead TSSOP, 8-lead

USON and 5-lead SOT-23/TSOT-23 packages. A standard 2-wire serial interface is used to address all

applications.
