Product details

What this Cortex-M4 brings to a control node

The STM32L433VCT6TR: It's built for applications that need the DSP and FPU capability of the M4 core without the power budget of a higher-performance part — think sensor fusion, motor control with FOC, or a CAN-connected industrial I/O module.

The 64 KB SRAM supports a modest RTOS heap and double-buffered ADC buffers. Connectivity includes CAN, USB, and multiple UART/SPI/I²C.

Temperature grade and package — where it lives on the board

The exposed pad should be stitched to the ground plane with thermal vias if the MCU drives multiple peripherals at 80 MHz.

Frequently asked questions

What is the maximum clock speed of STM32L433VCT6TR?

The STM32L433VCT6TR runs at 80 MHz. That's the core clock from the ARM Cortex-M4 with FPU, and the flash wait states need to be configured accordingly when running above 48 MHz.

Is STM32L433VCT6TR compatible with STM32L433VCT6?

Yes, the STM32L433VCT6TR is functionally identical to the STM32L433VCT6 — the 'TR' suffix indicates Tape & Reel packaging for automated assembly. The die, firmware, and pinout are the same.

What is the equivalent part for STM32L433VCT6TR?

The closest functional equivalent is the STM32L151CBU6A from the STM32L1 series. It's pin-compatible and offers similar analog peripherals, but runs a Cortex-M3 at 32 MHz with less Flash and fewer I/O — a cost-optimized fallback, not a direct performance swap.
