Description
The Atmel® AT24C16C provides 16,384-bits of serial electrically erasable and pro-
grammable read-only memory (EEPROM) organized as 2,048 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 AT24C16C is available in
space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead UDFN, 8-lead
XDFN, 5-lead SOT23, and 8-ball VFBGA Packages and is accessed via a Two-wire
serial interface. In addition, the AT24C16C operates from 1.7V to 5.5V.
