Product details

What this MCU is and where it fits

The STMicroelectronics STM32L433CCY3TR is a 32-bit ARM Cortex-M4 microcontroller from the STM32L4 series, built for low-power operation without sacrificing processing headroom. It runs at 80 MHz and packs 256 KB of Flash program memory and 64 KB of RAM, making it a fit for sensor-fusion nodes, portable instrumentation, and battery-backed control loops where extended temperature range (-40°C to 125°C) is required. The wide supply range from 1.71 V to 3.6 V lets it run directly from a single Li-ion cell or two alkaline cells, simplifying the power rail design.
