This density is the largest in the 24LC family — enough to hold a full firmware image, calibration tables, or configuration logs for an embedded controller without bank-switching. ## Industrial temperature range and package Write-cycle time is 5 ms per word or page. For a 128-byte page write, the total programming time is 5 ms plus the I²C addressing overhead — budget this into the firmware update routine so the host does not time out waiting for the ACK poll. ## Lifecycle and compliance The part is ROHS3 compliant, meeting EU and California restrictions without exemption conflicts. ## Sourcing and availability Available in Tape & Reel (TR) for volume pick-and-place or Cut Tape (CT) for prototype runs.","metaTitle":"Microchip 24LC1025T-E/SN EEPROM, 1 Mbit I²C 400 kHz 8-SOIC","metaDescription":"Microchip 24LC1025T-E/SN 1 Mbit serial EEPROM, I²C interface, 400 kHz clock, 2.5-5.5 V supply, -40°C to +125°C, 8-SOIC.
