Shenzhen Meiyuxin Technology Co., Ltd. [distributing ST microcontrollers] STM32U575AII6 ARM microcontrollers - MCU Ultra-low-power FPU Arm Cortex-M33 Quality assurance New original! ! !

Product Description:

The STM32U575AII6 device belongs to a family of ultra-low-power microcontrollers (STM32U5 series) based on the high-performance Arm® Cortex®-M33 32-bit RISC core. They operate at frequencies up to 160 MHz. The Cortex®-M33 core has a single-precision FPU (Floating Point Unit) that supports all Arm® single-precision data processing instructions and all data types. The Cortex®-M33 core also implements a full set of DSP (Digital Signal Processing) instructions and an MPU (Memory Protection Unit) for enhanced application security.

STM32U575AII6 These devices embed high-speed memory (up to 2 MB of Flash and 786 KBSRAM), an FSMC (Flexible External Memory Controller) for static memory (for devices in packages 90 pins and above), two Octo-SPI Flash memory interface (at least one Quad-SPI available for all packages) and a wide range of enhanced I/O and peripherals connected to three APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.

STM32U575AII6 These devices provide compliance with TBSA (Trusted Secure Arm® Based Architecture) requirements. It embeds necessary security features to implement secure boot, secure data storage and secure firmware updates. In addition to these features, the device includes a secure firmware installation feature that allows customers to ensure the supply of code during their production. Flexible lifecycle is managed with multi-level readout protection and password debug unlock. Benefit from secure peripherals, memory and I/O, and privileged configuration of peripherals and storage.

STM32U575AII6 The device has multiple protection mechanisms for embedded flash and SRAM: read protection, write protection, protection and hidden protection areas. These devices embed multiple security-enhancing peripherals: DPA-resistant, HASH hardware accelerator, and true random number generator. The device provides active tamper detection and protection against transient and environmental perturbation attacks, thanks to several internal monitors that generate secret data erasure against attacks. This helps meet PCI requirements for point-of-sale applications.

STM32U575AII6 These devices provide a fast 14-bit ADC (2.5 Msps), a 12-bit ADC (2.5 Msps), two comparators, two operational amplifiers, two DAC channels, an internal voltage reference buffer, a low-power RTC , four 32-bit general-purpose timers, two 16-bit PWM timers dedicated to motor control, three 16-bit general-purpose timers, two 16-bit basic timers and four 16-bit low-power timers.

STM32U575AII6 These devices support an MDF (Multifunction Digital Filter) with six filters dedicated to the connection of an external sigma-delta modulator. Another low-power digital filter is dedicated to embedded audio signals (ADF), one of which supports voice activity detection. The device also embeds a dedicated Chrom-ART accelerator for graphics applications, and a math accelerator (trigonometry accelerator plus filter math accelerator). Additionally, up to 24 capacitive sensing channels are available. These devices also have standard and advanced communication interfaces such as: four I2C, 3 SPI, 3 USART, 2 UART, 1 low-power UART, 2 SAI, 1 digital camera interface (DCMI), two One SDMMC, one FDCAN, one USB OTG full speed, one USB Type-C /USB Power Delivery controller and one universal synchronous 8-bit/16-bit PSSI (Parallel Data Input/Output Slave Interface).

STM32U575AII6 These devices operate in the temperature ranges of –40 to +85 °C (+105 °C junction) and –40 to +125 °C (+130 °C junction) from a 1.71 to 3.6 V supply. A comprehensive set of power-saving modes allows the design of low-power applications. Many peripherals, including communication, analog, timer and audio peripherals, can feature direct memory access and autonomous to stop mode thanks to LPBAM support (Low Power Background Autonomous Mode). Several independent power supplies are supported, such as analog independent power inputs for ADC, DAC, OPAMP, and comparators, a 3.3 V dedicated power input for USB and up to 14 I/Os, which can be independently supplied as low as 1.08 V. A VBAT input is provided for battery backup to preserve RTC functionality and back up 3232-bit registers and 2 KB SRAM.
