I've been considering going with a PIC24H on my next project (need many analog inputs...the PIC24HJ128GP510 has 32 12-bit ADC's), and as I was trying to find some parts to sample I found that the PIC24's aren't available as 5V parts. What's up with that? That is going to be a problem with some of the devices I plan on using with the PIC24, notably some 5V SPI devices and an LCD. Why would Microchip not produce 5V versions of these devices? In applications where low power consumption is not a requirement I can't see why one would want to migrate their designs to 3V unless I'm missing something.
