Description
The Atmel® AT24C64B provides 65,536 bits of Serial Electrically Erasable and
Programmable Read-Only Memory (EEPROM) organized as 8,192 words of 8 bits
each. The device’s cascadable feature allows up to eight 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 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.
