For people in this newsgroup that has been wondering...

Key features
* ATmegaAVR core (just higher frequency)
* 1.6V-3.6V operation
* Flash (max 384 kB)/SRAM/EEPROM
* 32 Mhz operation (max 32 MIPS)
* 44/64/100 pin package
    The pinout allows a design to use 44,64 and 100 pin concentric pads
    with S/W compatability. Pin multiplexing will be identical for
    all I/O ports, Larger devices will have extra ports, not different
ports.
* 12 bit 2 Ms ADC/1 Ms DAC
* 4 level interrupts
* 4 channel double buffered DMA
* Advanced timers for Motor control
* Fancy new event system
* 2 uA in sleep w Brownout protection and 32 kHz osc.
* 100 nA in deepest sleep mode
* External bus in larger devices with SRAM/SDRAM support

Only thing missing is a LCD segment driver.  Otherwise, we would jump
right into it.- Hide quoted text -

Atmel introduced the SAM7L series a few days ago, which is low power
and has an LCD segment driver, but meager SRAM (always something!)

http://www.atmel.com/dyn/corporate/view_detail.asp?FileName=AT91SAM7L...

But it does not come in 44 pins.  We are small people working on small
projects, so smaller chip is better.  We need 16K flash, 4 A2D and
12x4 or 8x8 segmented LCD.- Hide quoted text -

I think only microchip makes small 28 and 44 pin LCD  devices that are
close to what you need

Yes, I think the 16F913 w/ 28 pin QFN is what I need.  Unfortunately,
I have to learn pic now.- Hide quoted text -

you have my sympathies

is your "small" constraint more size or price? you can use any old
micro to drive an segmented LCD, but requires external parts (cheaper
but bigger)
