Description
The AT24C32/64 provides 32,768/65,536 bits of serial electrically erasable and pro-
grammable read only memory (EEPROM) organized as 4096/8192 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 applica-
tions where low power and low voltage operation are essential. The AT24C32/64 is
available in space saving 8-pin JEDEC PDIP, 8-pin and 14-pin JEDEC SOIC, 8-pin
EIAJ SOIC, and 8-pin TSSOP packages and is accessed via a 2-wire serial interface.
In addition, the entire family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to 5.5V),
2.5V (2.5V to 5.5V) and 1.8V (1.8V to 5.5V) versions.
