STMicroelectronics, 16 bit ARM Cortex M33, STM32H523xx Microcontroller, 250 MHz, 256kB FLASH, 144-Pin UFBGA

The STMicroelectronics devices are high-performance microcontrollers of the STM32H5 series, based on the high-performance Arm Cortex M33 32-bit RISC core. They operate at a frequency of up to 250 MHz The Cortex M33 core features a single-precision floating-point unit (FPU), which supports all the Arm single-precision data-processing instructions and all the data types. This core implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) that enhances the application security. The devices embed high-speed memories (512 Kbytes of dual bank flash memory and 272 Kbytes of SRAM), a flexible external memory controller (FMC) for devices with packages of 100 pins and more, one OCTOSPI memory interface (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.
