As seen in PTN194501A, a lot of MCUs like MB9BF458RPMC-G-JNE2 migrate its name to CY9BF568RPMC-G-MNE2. Question is: When will be this newly named MCUs available by large distributors like Mouser, Digikey etc? Is there a time gap of availability upcoming for those MCUs?
They are available for placing order from distributors now, if not enough stock from them, you may refer to the standard lead time available from the distributors website, or Cypress website here.
Note, Cypress more recommends considering PSoC than MM MCU for new designs.
