Description
The Atmel
®
AT24C02C provides 2048-bits of serial electrically erasable and program-
mable 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 TSSOP, 8-lead JEDEC SOIC, 8-lead UDFN, 5-lead
SOT23 and 8-ball VFBGA packages and is accessed via a two-wire serial interface.
