Features
Description
The AT24C04B/08B provides 4096/8192 bits of serial electrically erasable and pro-
grammable 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)
accessed via a Two-wire serial interface. In addition, the AT24C04B/08B is available
in 1.8V (1.8V to 5.5V) version.
