Releasing your creativity STM32 F4 series CortexTM‑M4 MCUs

STM32 F4 series 32‑bit Flash MCU, 180 MHz/225 DMIPS, with DSP instructions, floating point unit and advanced peripherals ST is extending its range of target applications with the STM32 F4 series. Based on the Cortex™‑M4 core, this series opens the door to the digital signal controller (DSC) market. This extension to our STM32 product portfolio offers devices that are pin‑to‑pin and software compatible with the STM32 F2 series, but with more performance, DSP capability, a floating point unit, more SRAM, and peripheral improvements such as TFT LCD controller with graphic acceleration, SDRAM,...

CHROM‑ART ACCELERATOR USE CASES In applications using a TFT LCD display, graphical data generation can consume a lot of CPU bandwidth. To offload the CPU, a dedicated DMA has been developed by ST to perform graphic content copy from the frame buffer (internal or external RAM) to the display interface (FMC or TFT controller). This advanced graphic accelerator, the Chrom‑ART Accelerator, achieves twice as much performance versus the CPU. In addition to raw data copy, additional functionalities are supported such as image format conversion or image blending (image mixing with some...
