Please critique hopefully my last board revision...
It looks like you love to push buttons. Have you considered making RC debouncing? I would also recommend reading the application note for layout of your LM2674: http://www....

Which pins can be used if you will use ISP and JTAG
In order to program your atmega using ISP, you need to make sure that the ISP can actually send a stronger signal than whatever else is using those lines. That can be accomplished...

ATMEL data flash
My first guess is that you have an error in the code that reads the status register. You are reading the status register to make sure the chip is ready, right?

ATMEL data flash
The chip should be erased to all 0xFF's Also, there's a chip erase command which is preferred to deleting pages one at a time. AT45DBxxxD replaced the AT45DBxxxB series, IIRC it...

Frequency Counter IC?
http://search.digikey.com/script... has an fMax of 135-235 depending on input pin and voltage. Use this to divide down to a level you can handle with an avr or whatnot. Edit: bah...

Problems with AVR availability…
The cost for repackaging and handling is excessively big when buying single units. Especially stuff like the big atmegas in trays. IC's on tape are a lot easier to snip :)

How about this bad boy: http://www.st.com/stonline/produ... Seems to fit the bill very nicely. Edit: disregard that, it doesn't fit at all.

SPI LED Driver Needed
The first that comes to my mind is TLC5916 in a TSSOP package.

Serial Packet Library or Project?
Nope, seems like you've got most stuff covered. You probably need to keep a separate variable for the outgoing flow control state, since you absolutely need to disable UDRIE when...
