STM32L433CCT6
Overview
The STM32L433CCT6 is an ultra-low-power microcontroller based on the high-performance Arm Cortex-M4 32-bit RISC core operating at up to 80 MHz. It features 256 Kbytes of Flash memory and integrates a dedicated LCD controller and USB 2.0 crystal-less FS device, making it ideal for portable power-constrained designs.
Why Choose This Part
This MCU provides an excellent balance of performance and efficiency, achieving high benchmarks in low-power tests while offering an FPU for signal processing. The inclusion of a built-in LCD driver for up to 8x40 or 4x44 segments reduces the need for external display controllers in simple UI applications.
Applications
Getting Started
Development is best supported by the NUCLEO-L433RC-P board or the STM32L433G-EVAL evaluation tool. Engineers should utilize the STM32Cube ecosystem, including STM32CubeMX for clock and peripheral configuration and the STM32CubeIDE for C/C++ development.
Dev Boards
Development boards and breakout modules featuring the STM32L433CCT6 or compatible chips — ready to use for prototyping.
