STM32U575CGU3

This product is a 32-bit microcontroller based on the Arm Cortex-M33 core, integrating TrustZone security technology and a floating-point unit, delivering up to 240 DMIPS of performance. It provides up to 2 MB of Flash memory and 786 KB of SRAM. The device employs advanced low-power technology, supports a wide supply voltage range of 1.71 V to 3.6 V, and operates over a temperature range of -40 °C to +125 °C. It includes multiple low-power modes such as Stop mode and Standby mode, and supports a low-power background autonomous mode that allows peripherals to operate autonomously via DMA in deep sleep mode. The integrated power management unit incorporates an LDO and a switching buck converter with dynamic voltage scaling support. Security features include hardware isolation based on Arm TrustZone, protectable secure I/Os, memories and peripherals, as well as secure boot, secure firmware installation and upgrade support. It also offers a true random number generator, device ID, and active tamper detection. Rich connectivity peripherals include a USB Type-C/PD controller, USB OTG, multiple USART, SPI, I²C, CAN FD, SAI, and SDMMC interfaces. Analog peripherals include high-speed ADC, DAC, operational amplifiers, and comparators. Additionally, it features a graphics accelerator, math co-processor, capacitive touch-sensing channels, and comprehensive debug support.
