Microchip and many Microchip distributors offer preprogrammed microcontrollers. In this case, the binary image is provided to Microchip or the distributor. This solution is obviously less flexible if changes are made frequently to the preprogrammed firmware and does have MOQ implications, but can have advantages related to reduced production time for the end-product.
To request preprogramming of Microchip microcontrollers contact microchipDIRECT, your local Microchip sales office, or your distributor.
