Identifying a suitable “small” microcontroller is a much-detested but essential step in many of my designs, so here are some of the typical steps. Or no smaller than 1.

Thanks for the info but I’m actually wanting to create a new transmitter key fob that can store a set of PRNG’s codes. After analyzing all the u parameters, a decision that is not tightly tuned to the defined parameters often still makes sense. Any items must be returned in their original condition to qualify for a refund or replacement.

For small volumes on a client-billable product, this may not be a constraint, but for huge volumes, a 1 cent price difference adds up to a fair bit.
