None of us are with a BGA!!! :-)

For a first project that is a good idea.

Why so much for a first project?

AT91FR40162.
2 MB Flash + 256 kB SRAM in a BGA package.

That is sensible. It is not realy worth making your own board these
days. Gone are the days of MCU in 40 pin DIl sockets.

Buy a kit!
Why do you need so much memory?
What is the project

Not that good compared to the commercial compilers. (I assume you mean C
or C++) However if it is for your own use it is OK.

A lot of embedded coding standards prohibit the use of Malloc.

Whilst Modula is theoretically a good language finding a good
implementation is another matter. Also I think you will find that 99% of
the support for ARM will be in C or C++ Certainly all the free examples
from the chip vendors.
Your ]best bet is to buy a dev kit.

Hi group,
I am new to ARM7 microcontrollers and would like to hear from
experienced people what they recommend. I saw that the Philips ones are
pretty popular but ST have a built-in 1.8V regulator. What chip would
you recommend?
Are there any ARM7 with more than 64KB Ram and 1MB Flash?
I am not very keen in soldering - in fact I would prefer a ready made
and pretty small board with a chip on it so that I only need to add
power to get my first project going. Perfectly it should have a mounted
graphic LCD module and if possible 128KB Ram and 4MB Flash or more.
How good is the gcc compiler tool-chain for the ARM, code density etc?
Does everything work as expected? How about malloc and related
functions? Does the C++ frontend work for the ARM? As a fan of Modula
- I couldn't find it - any project with a Modula compiler?
Anything else you may want to share?
Best thanks in advance!
