* fast flash
- the process type (e.g. 0.1u process)
- power consumption
- Serial boot (also known as UART boot, ROM boot, and boot loader)
- wait states on the memory (1 wait state means you lose one clock cycle)
- PLL
- real time clock
- has eCos been ported to it?
- drivers
- software tools support (and what license is it under)
- internal interrupt handling
- clock generation - how many PLLs will we use
- internal voltage regulators - we want to avoid them
- memory read speeds and widths
- ADC speed - need at least 2.5KHz on each channel (not total)
- pin tradeoffs - what do we need and what do we have to give up to get it?
- how long to bring up internal oscillators?
- 5V tolerance on GPIO
