STMicroelectronics STM32U575/585

STM32U5 brings innovations with added value for your application :

• Increase battery life time and decrease power consumption.
• Low Power Background Autonomous Mode, saves power by enabling direct memory access (DMA) and ensure peripherals keep working while in stop mode.

Higher security with AES encryption and Public Key Accelerator (PKA) which are now side-channel hardware-resistant.

The ECC available on all the Flash and a part of SRAM increase the level of safety.

The Flash size is up to 2MBytes and 512kbytes and be erased and programmed up to 100k cycles.

The STM32U5 embeds also a new ADC 14 bit providing a better accuracy.

Key features

• Lower power consumption : LPBAM*, DMA and IP autonomous in LP mode
• Higher security : AES and PKA, side attack resistant
• Higher level of safety : ECC on Flash and SRAM
• Improved data storage : 100 kcycles for 512 kB of Flash
