The wide supply range lets it bridge a 3.3 V MCU and a 5 V legacy sensor on the same I2C bus without a level shifter — the 24AA16-I/SN treats both as valid Vcc. The 5 ms page write cycle time means firmware updates or calibration data writes complete within a single sensor polling interval; budget this into the write routine so the I2C bus is not held for back-to-back pages. ## 8-SOIC package and board integration Supplied in an 8-SOIC package (3.90 mm width) in Tube format. The 0.154-inch body width fits a standard SOIC-8 footprint with 1.27 mm pitch — no fine-pitch routing needed. The surface-mount profile reflows at standard lead-free temperatures without a special bake step, as the MSL is typically Level 1 for this series.","metaTitle":"Microchip 24AA16-I/SN 16Kbit I2C EEPROM, 400 kHz","metaDescription":"Microchip 24AA16-I/SN 16Kbit I2C EEPROM, 400 kHz bus, 900 ns access, 1.7-5.5 V, -40 to +85 °C, 8-SOIC.
