The Microchip 24CW1280 128Kbit serial EEPROM is organized as 16384 bytes of 8 bits each (8 Kbytes). It operates on voltage range of 1.6V to 5.5V. This EEPROM allows up to eight devices to share a common I2C (2-wire) bus. It contains a pair of programmable Configuration registers which allow certain device behaviours to be modified. These registers are the Write Protection Register and the Hardware Address Register.

Low-Power CMOS Technology
Self-timed write cycle (5 ms maximum)
Output slope control to eliminate ground bounce
Schmitt trigger inputs for noise suppression
Configurable via the Hardware Address Register (HAR)
Software write protection via the Write Protection Register (WPR)
More than one million erase/write cycles
Data retention greater than 200 years
ESD protection than 4000V
Hardware Slave Address ’000b’
Temperature ranges between -40°C and +125°C
5-Lead Plastic Small Outline Transistor package
