AI summary

24AA256T-I/SN-TUDI product

24AA256T-I/SN-TUDI is a 256 Kbit I²C serial EEPROM for nonvolatile configuration, calibration, and small data-storage tasks.

Best for

Nonvolatile parameter storage
Configuration and calibration data
I²C systems requiring up to 32 KiB storage

Avoid if

A larger EEPROM or faster interface is required
Writes may cross 64-byte page boundaries without firmware control

Check before use

Verify the 8-SOP footprint and pin orientation
Set A0, A1, and A2 for the required bus address
Tie WP low for writes or high for complete array write protection
