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!)

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.

I think that you might be able to create a simple LCD controller with the
X-Mega DMA controllers, timers and the event handling.
