Does anyone know of a cheap ARM (or other) based CPU that is not in a BGA package that has a built in TFT LCD controller? I would prefer one that can do at least 16BPP preferably all the way up to 24BPP.
I have seen the LPC247x from NXP and the price point is almost perfect, but they do not seem to exist in distribution anywhere...
Basically I just want something simple that I can use to make an SPI/I2C/UART/USB (or whatever) interface to a raw TFT display. Preferably one like the PSP or Nintendo DS displays. All the chips I have found are way too expensive and way over powered for what I want to do, plus you have to hang sdram and flash off them which drives the cost up even more. The perfect controller I think would be ARM7 based, have 256-512K of built in flash and up to 512K of built in SRAM. If it does not have enough ram adding SRAM is pretty cheap, so I could handle that expense. Something in the $10 range would be perfect...
If anyone knows of any chips that would fit the list and *actually exist* that would be awsome!
TIA,
Mike
