Description​​ ​​ 

The​​ EC24C64T​​ provides 65,536 bits of Serial Electrically Erasab le and Programmable Read-Only Memory (EEPROM) organized as 8,192 words of 8 bits each. The device offers an additional page, named the Identification Page(32 bytes). The Identification Page can be used to store sensitive application parameters which can be (later) permanently locked in Read-only mode. The device’s cascadable feature allows more devices to share a common 2-wire bus. This device is optimized for use in many industrial and commercial applications where low-power and low voltage operation are essential. The device is available in space-saving 8-lead SOIC, 8-lead TSSOP, 8-pad UDFN, 8-lead PDIP(1), 5-lead SOT23, and 8-ball UDFN packages. The entire family of packages operates from 1.7V to 5.5V.
