STMicroelectronics, 32bit ARM Cortex M33, STM32U3 Microcontroller, 96MHz, 1 Mbyte Flash, 64-Pin LQFP

The STMicroelectronics Ultra low power microcontrollers based on the high-performance Arm Cortex M33 32-bit RISC core. They operate at a frequency of up to 96 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. STM32U3 series are the first STM32 series based on near-threshold voltage technology to deliver breakthrough improvement in battery life.
