Just got samples in of the dsPIC33FJ128GP706.
Man the specs on this are AWESOME. It's faster than a dsPIC30, yet considerably lower power. It's also slated to be a fairly low price device relative to dsPIC30. On the downside, it's a 3.3v-only part so it's hard to interface with many devices. It also has no EEPROM.
The thing that I love is that it's got DMA that work with most of its modules. So you can tell the USART, ADC, DCI, etc to just store one memory location after another in RAM without interrupting the processor after every word. This is particularly useful for audio codecs which could otherwise be interrupting tens of thousands of times a sec. This will probably work well with Idle/Sleep mode to keep power way down.
Oh yes I can dig it. What CAN'T you do with this sort of power?
