description
the at24c01 provides 1024 bits of serial electrically erasable and programmable
read only memory (eeprom) organized as 128 words of 8 bits each. the device is
optimized for use in many industrial and commercial applications where low power
and low voltage operation are essential. the at24c01 is available in space saving
8-pin pdip, 8-pin msop, 8-pin tssop, and 8-pin jedec soic 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.
