It communicates at up to 400 kHz (I2C Fast Mode) and operates from a single 1.7V to 5.5V supply, making it a drop-in fit for 1.8V, 3.3V, or 5V logic rails. The 900 ns access time is the read-cycle time on the bus; the write cycle takes 5 ms per page or word. Packaged in a 6-pin SOT-23-6, it is meant for space-constrained boards in industrial control, automotive modules, and sensor nodes where non-volatile parameter storage or unique ID retention is needed. ## Temperature range and supply — rated for the harsh stuff The 1.7V minimum supply means it stays alive during a 1.8V rail brown-out, and the 5.5V max lets it sit on an unregulated 5V bus without an extra LDO. If your design lives in a 3.3V I2C domain, it works directly — no level shifting needed. The TR variant is the standard reel for pick-and-place; CT is for prototype or low-volume builds. Both ship in SOT-23-6, a 6-pin surface-mount package. Store the reels dry — MSL level is not stated here, but SOT-23-6 EEPROMs are typically MSL 1, so no bake required unless the seal is broken and the floor-life window has passed.","metaTitle":"Microchip 24AA025E64T-E/OT 2Kbit I2C EEPROM, SOT-23-6","metaDescription":"Microchip 24AA025E64T-E/OT 2Kbit I2C EEPROM in SOT-23-6, 400 kHz clock, 1.7V-5.5V supply, -40°C to 125°C.
