Low-power MCU for TFT display control

[MartinEnG]

Hi,

I am looking for a low-power MCU for a battery-powered device. The device will have a 3.51" TFT display with a resolution of 340×800. Which MCU or MCU family from your product portfolio would you recommend for this application? I would like the MCU to have support in GUI Guider. I hope you can help me.

Regards.

Walter.

Hi @koena57jim 

As @MartinEnG  said, LPC5X is a good choice.

We also recommend the MCX N9 series, such as the MCX‑N947. This family offers excellent low‑power performance and includes VGLite hardware acceleration, which is very helpful for smooth GUI rendering. It is also officially supported by GUI Guider.

MCX N94, N54, N53, N52 and N24 MCUs | NXP Semiconductors

If you’re building a battery-powered device with a 3.51″ TFT (340×800) display and want strong support in GUI Guider for fast UI development, a good choice from NXP’s MCU portfolio would be a member of their power-efficient general-purpose / crossover MCU families such as the LPC54000 / LPC546xx or one of the LPC55xx (Cortex-M33) series. GUI Guider is a free graphical UI design tool from NXP that works with their general-purpose and crossover microcontrollers and lets you design embedded GUIs using the LVGL graphics library with drag-and-drop ease, then export ready-to-compile code for use in MCUXpresso IDE or other supported toolchains. These LPC series parts balance low power consumption with enough performance and memory to drive larger TFTs like a 3.51″ panel while keeping battery drain modest, and they are supported directly by the GUI Guider toolchain
