Description
The AT24C64B provides 65,536 bits of serial electrically erasable and programmable
read only memory (EEPROM) organized as 8192 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 operation are essential. The AT24C64B is available in space saving
8-lead PDIP, 8-lead JEDEC SOIC and 8-lead TSSOP packages and is accessed via a
2-wire serial interface. In addition, the entire family is available in 2.7V (2.7 to 5.5V)
and 1.8V (1.8 to 5.5V) versions.
