Its AEC-Q100 qualification means it's been through the automotive reliability gauntlet — temperature cycling, ESD, and extended life testing — making it a fit for under-hood or chassis-mounted electronics where vibration and thermal swings are the norm. The supply voltage spans 1.8V to 3.3V, so it can run off a 1.8V core rail or a 3.3V I/O rail without a separate regulator — handy when you're consolidating supply domains on a mixed-voltage board.
This part is officially marked Obsolete by Microchip, meaning the manufacturer has stopped production and no longer accepts orders.
Standby power-down and package footprint
Housed in a 4-SMD no-lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm — a compact footprint that fits tight layouts, though hand-soldering is tricky without a hot-air station or reflow oven.
