Description
The AT24C02C
provides
2048 bits of
serial
electrically erasable and
programmable
read-only
memory
(EEPROM)
organized as 256 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 AT24C02C is available in
space-saving
8-lead PDIP, 8-lead
JEDEC
SOIC, 8-lead UDFN
,
5-lead SOT23, 8-lead TSSOP, and
8-ball VFBGA
packages
and is accessed
via
a Two-wire
serial
interface.
