STMicroelectronics STM32H7R and STM32H7S microcontrollers

The STM32H7R and STM32H7S microcontrollers from STMicroelectronics can be used at 600 MHz and are suitable for integrators who require external storage. Additionally, while there’s less flash, the STM32H7R and STM32H7S support bootflash instead of the traditional boot ROM. Some also offer a NeoChrom GPU.

The general-purpose line, the STM32H7R3/S3, features a Chrom-ART accelerator for 2D graphics. It has been designed to help enhance graphical user interfaces by fetching assets from memory faster and accelerating operations like 2D copies, transparencies or alpha-blending. Consequently, Chrom-ART is designed to enable modern UIs on even the most constrained devices like smart watches and wearables.

The STM32H7R7/S7 features a NeoChrom GPU. The hardware IP is a 2.5D accelerator optimising texture mapping with bilinear and point sampling. It also accelerates animations and drawing operations, thereby helping to offload the Cortex-M7. The NeoChrom GPU also has an 8-bit Octal Serial Peripheral Interface (OSPI) or a 16-bit high-speed interface (HSPI) to fetch assets from the external memory modules faster and deliver them to the L2 cache.
