Description
The
AT24C256C
provides
262,144
bits
of
serial
electrically
erasable
and
programmable read-only memory (EEPROM) organized as 32,768 words of 8 bits
each. The device’s cascadable feature allows up to eight devices to share a common
two-wire bus. The device is optimized for use in many industrial and commercial
applications where low-power and low-voltage operation are essential. The devices
are available in space-saving 8-lead JEDEC PDIP, 8-lead JEDEC SOIC, 8-lead Ultra
Thin SAP, 8-lead TSSOP, and 8-ball dBGA2 packages. In addition, the entire family is
available in a 1.8V (1.8V to 5.5V) version.
