Hi,
I'm searching for a

           ==>  NON BGA   <==

Controller (32 Bit) with the following requirements:

1. minimal 400MHz internal clock frequency
2. external Data+Adressbus (min 16+22) Pins required
3. minimal 32 signal pins free after 2)
4. 1xx SD/MMC card connector
5. 1x USB
6. 1..2x SPI
7. 1..2x IIC


 Point 1..3 is essential, the rest can be adapted if 1..3 IS available

Would you please give me some suggestions?

Thanks and have a nice day

Volker

The clock speed you require in addition to non-BGA is severely limiting. 
The only micro I found that matches these two attributes is Freescale 
MCIMX233CAG4B, but I don't know about your other requirements.  It has 
USB, SPI, IIC, but I'm not so sure about items 1 - 4.

I propose to skip your silly -NON BGA- requirement!

@ Jerry: thanks for that Freescale hint.

@ Peter: thanks for your contribution, but why silly?
this is a private project which means... BGA@HOME is not so easy for me. 
Congratulation if its easy for you, Peter. I cannot solder BGA and THIS 
is the only reason for my question.

Further comments are highly welcome (but I'm not sure if we should warm 
up how so solder BGA at home ;-) )

You may also use a XMOS chip, the L1 version in QFP128. The fine pitch 
(0.4 mm) makes it a bit more critical to solder than 0.5 but it may 
work. It has 64 IOs in total and it runs at 400 MHz, at least 4 threads.
