Procurement Notes

Verify the specific ordering suffix 'P' against official Analog Devices documentation to confirm its exact impact on packaging or firmware status. Confirm current availability through authorized distributors as Maxim Integrated products are now managed by Analog Devices. Ensure compliance with RoHS directives and verify lead times directly with suppliers.

Selection Notes

Select this component for designs requiring integrated smart card, USB, and keypad interfaces in a single chip. The 44-pin QFN package suits space-constrained portable applications. Consider the 64KB Flash capacity for firmware storage needs and ensure the system design accommodates the required 6MHz to 12MHz crystal oscillator.
