Ordering Information/Selector Guide
Note: The 4-digit suffix “-0000” indicates a microcontroller in the default state with the flash memory unprogrammed. Any value other
than 0000 indicates a device preprogrammed at Maxim with proprietary customer-supplied software. For more information on factory
preprogramming of these devices, contact Maxim at https://support.maximintegrated.com/micro. Information on masked ROM devices
and bare die versions for most of these devices are available. Contact the factory for availability.
