FM24C128A Shanghai Fudan Microelectronics Co., Ltd., FM24C128A Datasheet - Page 3

• Manufacturer Part Number: FM24C128A
• Description: 2-wire Serial Eeprom
• Manufacturer: Shanghai Fudan Microelectronics Co., Ltd.

Description
The FM24C128A/256A provides 131,072/262,144 bits of serial
electrically erasable and programmable read-only memory
(EEPROM) organized as 16,384/32,768 words of 8 bits each.
The device’s cascadable feature allows up to 8 devices to
share a common 2-wire bus. The device is optimized for use in
many industrial and commercial applications where low-power
and low-voltage operations are essential.
Features
Absolute Maximum Ratings
*NOTICE: Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or
any other conditions beyond those indicated in the operational
sections of this specification are not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device
reliability.
