Description
The AT24HC04B provides 4096 bits of Serial Electrically Erasable and
Programmable Read-Only Memory (EEPROM) organized as 512 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
AT24HC04B 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 1.8V (1.8V to 5.5V) version.
