AT24C08B
Description
The AT24C04B/08B provides 4096/8192 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. The AT24C04B/08B 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 TSSOP, and 8-ball dBGA2 packages and is
accessed via a Two-wire serial interface. In addition, the AT24C04B/08B is available in
1.8V (1.8V to 5.5V) version.

Note:
For use of 5-lead SOT23
4K:
The software A2 and A1 bits in the
device address word must be set to zero
to properly communicate.
8K:
The software A2 bit in the device
address word must be set to zero to
properly communicate.
