STM32F429 peripheral pin usage

Question asked by P. Chung on Jun 16, 2014

Hello,

I am making a device that utilizes multiple peripherals ofthe STM32F429. I’ve tried a few combinations of peripheral pins to use all ofthese devices at the same time with the STM32F429II (176LQFP) but it seemsmajority of the pins overlap. The devices I must use are


- TFT LCD Controller (24Bit RGB 888)
- 32 Bit SDRAM via FMC
- DCMI
- 8 ADC input lines
- USB
- SPI
- USART
- A few EXTI interrupt lines

It seems that the combination of these peripherals is onlypossible on the STM32F429BI (208LQFP) or the STM32F429NI (216BGA), but thesedevices are not yet available from ST for me to start working with. It seems myproblems begin as early as trying to use 32Bit SDRAM with a TFT LCD controller.Does anyone know if there’s anything I’m missing where I can use all of thesedevices on the 176LQFP package?

Thanks,

Patrick
