Its 1.7V to 5.5V supply range lets it sit on a 3.3V or 5V rail without a separate regulator, which simplifies the power tree in mixed-voltage sensor modules or industrial controller boards. The 900 ns access time and 5 ms write cycle per word or page are typical for this density class — the write cycle is the throughput bottleneck for frequent logging, but for storing calibration coefficients or configuration tables at power-up, it is more than adequate. ## Supply voltage and temperature grade for BOM fit Rated from 1.7V to 5.5V, this part works with both 3.3V and 5V logic families without a level shifter on the I²C lines — a common requirement when pairing a 3.3V MCU with a 5V sensor or actuator. The industrial temperature range of -40°C to 85°C covers outdoor telecom cabinets, factory-floor PLCs, and automotive cabin environments, though it is not rated for under-hood or engine-bay use.","metaTitle":"24AA02H-I/SN 2Kbit I²C EEPROM, 1.7V-5.5V, SOIC-8 - Microchip","metaDescription":"24AA02H-I/SN is a 2Kbit (256x8) I²C EEPROM from Microchip, 400 kHz clock, 1.7V-5.5V supply, -40 to 85°C, SOIC-8.
