Microcontroller series boosts system-on-chip security
Summary
Challenging the perception that increased performance comes with power dissipation constraints for developers, the STM32H5 MCUs also improve energy efficiency by leveraging STs advanced 40 nm CMOS process technology and improved on-chip power-conversion circuits. With these MCUs, power dissipation is no longer a constraint when using a 250 MHz device in harsh environments where the ambient temperature can reach 125°C. In addition, STM32H5 MCUs are SIL-ready for products that must meet an appropriate safety integrity level (SIL), thanks to native hardware features that address a wide range of industrial and medical applications. Enhanced I/Os and peripherals reinforce security with a HASH hardware accelerator and a true random number generator. The devices are offered in five packages from 25-pin to 64-pin, requiring a 1.71 to 3.6 V power supply, and operate from -40 to +85 °C/105 °C and up to 125 °C at low dissipation (+130 °C junction) temperature.
