STM32H7 Dual-Core Series High-Performance MCUs
STMicroelectronics' STM32H7 dual-core series of high-performance MCUs with Arm® Cortex®-M7 and -M4 cores
STMicroelectronics' STM32H7 series is expanding with the addition of several variants coming in dual-core Arm Cortex-M7 and Cortex-M4 able to run up to 480 MHz and 240 MHz, respectively. The former single-core Cortex-M7 variants also benefit from this frequency increase and can now run up to 480 MHz as well. The dual-core variants are offered with an embedded SMPS which provides an improved dynamic power efficiency. Some variants are now proposed with the MIPI-DSI phy to drive high-resolution displays. The STM32H7 series remains the highest performance microcontroller with embedded Flash available on the market.
