AT24C16B
2. Description
The AT24C16B provides 16384 bits of serial electrically erasable and programmable
read-only memory (EEPROM) organized as 2048 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 AT24C16B is available in space-saving
8-lead PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Thin Mini-MAP (MLP 2x3), 5-lead
SOT23, 8-lead Ultra Lead Frame Land Grid Array (ULA), 8-lead TSSOP, and 8-ball
dBGA2 packages and is accessed via a Two-wire serial interface. In addition, the
AT24C16B is available in 1.8V (1.8V to 5.5V) version.
