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
Hi, I tried to find something with google and other serch engine but failed. Is there anybody who has a similar problem or can please give me an advice how to search in a better way? Each helpful hint is really appreciated Thanks
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.
