Description
The Atmel® AT24C04C and AT24C08C provides 4,096/8,192 bits of Serial
Electrically Erasable and Programmable Read-Only Memory (EEPROM)
organized as 512/1024 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. AT24C04C/08C is available in space-saving 8-lead PDIP,
8-lead JEDEC SOIC, 8-lead TSSOP, 8-pad UDFN, 5-lead SOT23, and 8-ball
VFBGA packages and is accessed via a 2-wire serial interface.
