The 3.5 µs access time sets the minimum SCL high and low pulse widths; at 400 kHz the bus timing is tight enough that the master's I²C peripheral must meet the 2.5 µs data-hold requirement. The 5 ms write-cycle time means the part is busy after every page or byte write — the master polls the ACK bit or waits the full period before the next command. ## SOIC-8 footprint and reflow profile No special pad geometry or via-in-pad required; a standard 0.050-inch pitch SOIC land pattern places it cleanly. Tube delivery means the parts ship in anti-static tubes, not tape-and-reel. For high-volume pick-and-place, plan a tube feeder or a bulk-to-tape conversion step. ## Active production and compliance posture ROHS3 compliance covers the standard restricted substances (lead, mercury, cadmium, hexavalent chromium, PBBs, PBDEs, and four phthalates).","metaTitle":"Microchip 24LC01B/SN 1Kbit I²C EEPROM, SOIC-8, 400 kHz","metaDescription":"Microchip 24LC01B/SN 1Kbit serial EEPROM, I²C interface, 400 kHz clock, 2.5-5.5V supply, SOIC-8 package, commercial temp.
