Key benefits

  • run a complete MPU-like graphical user interface on a simple microcontroller
  • keep two frame buffers inside the MCU (2.5 Mbytes of SRAM)
  • address small applications thanks to 100- to 216-pin packages (LQFP 100, LQFP 144, BGA144 and more)
  • protect user data thanks to an additional encryption accelerator engine (AES, PKA, and OTFDEC).

TouchGFX GUI Software now supports the NeoChrom GPU 2.5D accelerator to help with scalability and animations. This new processing unit optimize animations such as flips, spins, scaling and more, vastly increasing the number of frames per second.

Smoother & richer graphics with NeoChrom GPU

Today, STM32U599/5A9 lines are the first MCUs to embed the Neochrom GPU accelerator, offering hardware optimizations specific to STM32 MCUs.
