I have been reading through the data sheets at Freescale and I was wondering. Could we remove the MK20DX128VLH5 and put the Mk20DX256VLH7 in its place?
According to the fact sheet the 256VLH7 has double the flash and 4 times the sram. The footprints are the same and the pin layout is the same other then the 256VLH7 having more functions on a few pins.
Has anyone else considered this? Would there be any glaring downsides to upgrading the uChip? Other then a cost increase?
Thoughts, comments, beat-downs welcome
