You might be better off with 2 chips, a 'uC of your choice', and a LCD driver chip ?. On the subject of the AT91SAM7L - anyone seen a price on the Eval Kit - that has a nice looking LCD ? -jg

We need an external charge pump and regulator to constant 3V from 2V to 6V battery range. Luminary Micro ARM Cortex M3 is also possible.

It will be a combinations of transistors, diodes, resistors, capacitors and mutual inductors. Actually, we already have the circuit in the production device, but they are not yet populated and activated. We just want to make sure there is enough space for it. The power circuit is on a separate circuit board, so no space limitations there. However, the uC must fit inside the 0.8" width of the LCD glass. It is very tight with the 64 pins MLF.> > -- > Best Regards, > Ulf Samuelsson > This is intended to be my personal opinion which may, > or may not be shared by my employer Atmel Nordic AB
