I was doing a search for an AVR processor today using the selection guide from Microchip found here (selected 8-bit AVR on previous page):
By chance, I noticed that the processor I currently use (ATMega1284p) was not listed even though I had not selected anything that would have excluded it.
I checked and it's still in production so why would it not be listed?
BTW: I'm looking for the lowest cost AVR that can use JTAG, 8 ADCs, SPI, and TWI simultaneously (i.e.: no shared pin conflicts).
