Product Summary

The AT24C256B-PU Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 512/1024 words of eight bits each. The AT24C256B-PU is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The AT24C256B-PU is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-pad UDFN, 5-lead SOT23, and 8-ball VFBGA packages and is accessed via a 2-wire serial interface.
