STMicroelectronics STM32H7R & STM32H7S
STM32H7R & STM32H7S Lines - Scalable & secure bootflash microcontrollers
The new STM32H7R/S lines are a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 Kbytes of user bootflash, 620 Kbytes of flexible SRAM, and 32 x 32 Kbytes of cache with Flex ECC. Both lines support high speed external memory interfaces with XiP.
- The STM32H7R3/S3 is a general-purpose line-up designed to achieve high performance and provide a rich feature set for cost-optimized designs. It comes in 10 different packages options, ranging from cost-effective 68 to 225 pins, to achieve the best performance at the lowest cost.
- The STM32H7R7/S7 is a graphics line with NeoChrom GPU that enables smoother, richer MPU-like GUIs with advanced capabilities. It comes with 5 different packages options to achieve the best performance at the lowest cost. This line enables MPU-like GUIs thanks to NeoChrom GPU, JPEG codec, and LTDC, with minimum CPU interventions.
In terms of security, both lines target SESIP3 and PSA certified level 3 certifications. The STM32H7S prioritizes security by offering the capability to encrypt and decrypt information directly from flash and RAM on-the-fly, making it the first STM32H7 to do all this. Now, thanks to on-the-fly encryption/decrypt (MCE), the STM32H7S can protect user data from intruders, among other things.
Thus, these new microcontrollers combine performance, scalability, and security accommodating the most demanding application requirements in IoT, medical and industrial settings. They offer developers more design freedom to achieve MPU-like applications at a low cost, facilitated by a simpler development process thanks to the MCU's ecosystem.
