STMicroelectronics STM32U585OIY6QTR, 8bit ARM Cortex M33 Microcontroller, STM32, 160MHz, 2 Mb Flash, 90-Pin WLCSP

The STMicroelectronics devices belong to an ultra-low-power microcontrollers family (STM32U5 series) based on the high-performance Arm Cortex M33 32-bit RISC core. They operate at a frequency of up to 160 MHz The Cortex M33 core features a single-precision FPU (floating-point unit), that supports all the Arm single-precision data-processing instructions and all the data types. The Cortex-M33 core also implements a full set of DSP (digital signal processing) instructions and a MPU (memory protection unit) that enhances the application security. The devices embed high-speed memories (2 Mbytes of flash memory and 786 Kbytes of SRAM), an FSMC (flexible external memory controller) for static memories (for devices with packages of 90 pins and more), two Octo-SPI flash memory interfaces (at least one Quad-SPI available on all packages) and an extensive range of enhanced I/Os and peripherals connected to three APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.
