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 MiniMAP (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. Absolute Maximum Ratings Operating Temperature ..........................?55degC to +125degC Storage Temperature ...........................?65degC to + 150degC Voltage on Any Pin with Respect to Ground ..................................? 0.1V to +7.0V Maximum Operating Voltage ................................... 6.25V DC Output Current ................................................ 5.0 mA . Memory Organization AT24C04B, 4K SERIAL EEPROM: Internally organized with 32 pages of 16 bytes each, the 4K requires a 9-bit data word address for random word addressing. AT24C08B, 8K SERIAL EEPROM: Internally organized with 64 pages of 16 bytes each, the 8K requires a 10-bit data word address for random word addressing.
