Is there a KiCad symbol and footprint for the MEC1406-NU?
Yes. The symbol is EasyEDA_Cloud:MEC1408-NU and the footprint Package_QFP:TQFP-128_14x14mm_P0.4mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MEC1406-NU?
TQFP-128(14x14), with 128 pins. Its footprint is drawn on this page.
Where is the MEC1406-NU datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the MEC1406-NU?
JLCPCB lists it as part C638325, with 0 in stock; the sellers' links on this page open their listings.
What can replace the MEC1406-NU?
