The Microchip 93C86C-I/MS is a 16 Kbit serial EEPROM using the Microwire interface, organized as 2K x 8 or 1K x 16. Typical applications include storing calibration constants, configuration tables, or small firmware patches in industrial controls, telecom line cards, and metering equipment where the bus is already 5V and the footprint needs to stay small.
The 8-MSOP package is a small outline with a 3.00 mm body width — about half the footprint of an SOIC-8. The tube shipping medium means the parts are delivered in anti-static tubes, not tape and reel; if your pick-and-place line expects tape, order the tape-and-reel suffix variant.
Active lifecycle, but RoHS non-compliant
If your assembly must meet RoHS 2/3, you will need the RoHS-compliant suffix (e.g., 93C86C-I/MS with a different lead finish code). Check the latest PCN from Microchip for any pending transition.
