AT24C04B/08B is an 8-bit serial electrically erasable and programmable read-only memory (EEPROM) organized as 512/1024 words, each 8 bits. 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.
The AT24C04B/AT24C08B EEPROMs offer 4‑Kbit (512 × 8) and 8‑Kbit (1024 × 8) memory organized in 16‑byte pages. They operate over a wide voltage range (1.8 V to 5.5 V) and feature a two‑wire serial interface, write‑protect pin, and low‑power standby mode. Multiple package options are available, including PDIP, SOIC, Ultra‑Thin Mini‑MAP, SOT23, TSSOP, and dBGA2.
The datasheet details absolute maximum ratings, DC and AC electrical characteristics, timing diagrams, and bus protocols. Key parameters such as supply voltage, operating temperature, write‑cycle time, endurance, and clock frequency are specified, enabling designers to integrate the devices into industrial and commercial applications.
