Selection Notes

Good for: reuse when package, electrical ratings, footprint, and assembly class match the project constraints
Avoid when: Not captured yet.
Known layout constraints: Verify package land pattern, decoupling requirements, thermal pad, RF keepouts, crystal routing, and boot straps from the datasheet.
Equivalent search hints: match category ethernet-stack-controller, interfaces spi, uart, ethernet, package LQFP-64M(10x10), and EasyEDA footprint UUID 6aaddb138b3c4de991ad231a075d4644.
