Description
STM32L433VCT3 is an ultra-low-power 32‑bit MCU from STMicroelectronics’ STM32L4 family. It uses an ARM Cortex‑M4F core (DSP/FPU) and can run up to about 80 MHz, providing a good balance of performance and energy efficiency for battery-powered and sensor‑rich apps.
Key points:
- Core and performance: Cortex‑M4F with DSP/FPU for efficient signal processing.
- Power: multiple run/stop/standby modes and voltage scaling for very low energy use (typical supply 1.65–3.6 V).
- Peripherals: USB Full‑Speed, LCD controller, timers, DMA, SPI/I2C/UART, 12‑bit ADCs, DACs, RNG, and a hardware crypto engine.
- Memory: flash and RAM sizes vary by package; designed for compact, cost‑effective implementations.
- Package: VCT3 indicates a specific physical variant/package.
- Development: supported by STCubeMX/HAL/LL libraries and STM32CubeIDE.
Typical applications: wearables, portable medical devices, sensors, and IoT nodes requiring low power with decent performance.

Equivalent
Clarifying question: Do you want (a) STMicroelectronics equivalents within the STM32L4 family (pin‑compatible, same package), or (b) cross‑vendor equivalents (NXP, Microchip, etc.)? Also confirm package (e.g., LQFP48/64) and the required memory/peripherals. With that, I can list exact substitutes or cross-references.
Pinout
- Pin count: 100 pins (LQFP-100 package)
- Function: 32-bit ARM Cortex-M4 microcontroller (STM32L4 series) for embedded apps, with integrated Flash/RAM and multiple peripherals; supports up to high-speed operation and low-power modes.
