MHz. In Stop mode, the power consumption is 120 μA typical, which is 3 times lower versus the STM32F405/415/407/F417.

Graphics: As opposed to the STM32F429/439, the STM32F427/437 does not embed an LCD-TFT controller interface. However, it is possible to connect a display to the parallel or serial interfaces and still take full advantage of ST’s Chrom-ART Accelerator? graphics accelerator performing content creation twice as fast as the core alone. This graphics accelerator supports efficient 2-D raw data copy, as well as image blending or image format conversion (mixing and transparency). As a result, the Chrom-ART Accelerator boosts graphics content creation and saves processing bandwidth of the MCU core for the rest of the application. Integration :

With such memory integration, the need for external memory is reduced, allowing smaller, safer and low-emission PCB designs.

STM32F429/439

The STM32F429/439 lines offer the performance of the Cortex-M4 core (with floating point unit) running at 180 MHz while reaching lower static power consumption (Stop mode) versus STM32F405/415/407/F417.

Performance: At 180 MHz, the STM32F429/439 deliver 225 DMIPS/608 CoreMark performance executing from Flash memory, with 0-wait states thanks to ST’s ART Accelerator. The DSP instructions and the floating point unit enlarge the range of addressable applications.

Power efficiency: ST’s 90 nm process, ART Accelerator and the dynamic power scaling enables the current consumption in run mode and executing from Flash memory to be as low as 260 μA/MHz at 180 MHz. In Stop mode, the power consumption is 120 μA typical, which is 3 times lower versus STM32F405/415/407/F417.

Graphics: The new LCD-TFT controller interface with dual-layer support takes advantage of

Chrom-ART Accelerator?. This graphics accelerator is performing content creation twice as fast as the core alone. As well as efficient 2-D raw data copy, additional functionalities are supported by the Chrom-ART Accelerator such as image format conversion or image blending (image mixing with some transparency). As a result, the Chrom-ART Accelerator boosts graphics content creation and saves processing bandwidth of the MCU core for the rest of the application. Integration:
