STM32H5: tailored for high-performance graphics & advanced connectivity
One STM32H5 platform, more design options
One STM32H5 platform, more design options
From 1 Mbyte to 4 Mbytes of flash, the STM32H5 series gives you more flexibility to balance memory, performance, security, and connectivity requirements within a single platform.
STM32H5Ex/Fx devices, with up to 4 Mbytes of flash, are now available from stock.
New STM32H543 and STM32H553 MCUs extend the family with a 1 Mbyte flash option, delivering STM32H5 performance, security, and connectivity in a more compact memory configuration.
