low cost, non-BGA MCU for dispays support by GUI Guider

[HansDampf]

Dear NXP experts,

we are searching for a MCU for displays (RGB and maybe SPI), what is supported by GUI Guider. The bigger displays up to 800x600 RGB565, the smaller up to 320x200 SPI. The design requires single side assembled PCBs, so no BGAs. My research brought up only a few possible parts (LPC54607/8/16/18/28), they are all in LQFP208 package, what is quite big. But they support SDRAM, what would enable even 1024x768x24. The iMxRT1xxx are either in BGA, or does not support LCDs. In the LPC55xx group I could non found non-BGA parts with LCD.

What would be NXPs suggestion for low cost display solutions, with single-side assembled PCBs (preferred 2 layer), RGB565 Interface, up to 800x600? I would need a bit more then 1MB RAM, so a external SDRAM (or HyperRAM, if supported by GUI Guider) need to be supported, if the on chip RAM is not that big.

And the same for a smaller design with SPI display, up to 320x200 pixel, 256kB internal RAM, also non-BGA, hopefully much smaller then the LQFP208?

Thank you,

Hans

Hi @HansDampf,

i.MX RT1010 is available in LQFP80 packaging.

LQFP100 packaging is available for i.MX RT1015, i.MX RT1020, i.MX RT1024.

LQFP144 packaging is available for i.MX RT1020, i.MX RT1024.

All of these are <LQFP208, compatible with GUI Guider and support LCDs, as well as external SRAM for higher performance.

Let me know if this helps!

BR,
Edwin.

Hi Edwin,

thanks for your list. The iMXRT parts you listed, are indeed smaller TQFP. But they seem not to have a display unit and RGB interface, so a display could only be connected by SPI or i8080 bus. In this case, an external display controller would be needed.

At least for small displays, connected by SPI, the iMXRT1011 is a solution. For bigger ones via RGB, I have the choice between LPC54607+SDRAM, or iMXRT102x+ext. LCD controller.

Thank you
