STM32L433CCU6TR Overview

The STM32L433xx series are ultra-low power microcontrollers based on the high-performance ARM® Cortex®-M4 32-bit RISC core operating at up to 80 MHz. The Cortex-M4 core features a floating-point unit (FPU) single precision and supports all Arm® single-precision data processing instructions and data types. It also implements a complete set of DSP instructions and a Memory Protection Unit (MPU) to enhance application security. STM32L433xx devices embed high-speed memory (up to 256 kbytes of flash, 64 kbytes of static memory), a quad SPI flash interface (available in all packages) and a wide range of enhanced input/output and peripherals, connected to two APBs bus, two ahb buses and one Matrix multiple STM32L433xx devices embed multiple protection mechanisms for embedded flash and static memory: read protection, write protection, proprietary code read protection and firewall.
