I'm looking for this chip: ARM920 or ARM926. NOT in BGA format (TQFP or LQFP) SDRAM controller LCD controller able to drive at least 320x200 color. Most ARM9 chips are either BGA or does not have an LCD controller. The LCD interface requires many more pins but I'm sure the maximum of 208 pins can include all the important ARM9 pins plus an LCD bus. I do not need many GPIO pins and 16-bit memory buses are fine. SD card interface, IDE, ethernet etc are fine.
Is this ARM possible?

However, it is ARM7 so that might not be powerful enough for what you need. Are you sure you need ARM9?

However as you have 200+ pin parts and 32 bit parts....... Isn't marketing fun. Who cares what it stood/stands for the LPC is the NXP designator for their chips. BTW what do CPM, PDP MPM, PLM etc stand for? -- \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ \/\/\/\/\ Chris Hills Staffs England /\/\/\/\/ /\/\/ chris@phaedsys.org www.phaedsys.org \/\/\ \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/

Ok, you were close with Switzerland (.ch) but still. An URL that would work is www.ronetix.com Too bad they do not publish prize information for their products. A real turn off IMHO. Markus

Semiconductor companies have to sell what the volume customers need. They need mostly small devices. Small devices with high pincount are usually in BGA packages. So, if a company makes a xQFP package with > 200 pins, there are probably not enough customers to make this a profitable device. Would you (and others) be willing to pay a much higher price for a xQFP package? The chips became so inexpensive because manufacturing has been streamlined to the high volumes only. This pricing make the chips interesting for hobby projects but there are those tough to handle packages.... Well it is a catch 22. Robert
