Product details

Active production, 72 MHz Cortex-M4 with DSP and FPU

The STM32F303RBT7TR: ARM Cortex-M4 core with single-precision FPU and DSP instructions, clocked at 72 MHz.

This is useful for current-sensing in motor drives, temperature monitoring, or generating analog reference voltages for external circuitry. The DMA controller offloads data transfers between peripherals and memory, which is critical when handling multiple ADC conversions or high-speed serial streams without CPU intervention. The I²S interface supports audio codec connections for voice or alarm systems.

This makes it suitable for new design-ins and production ramps without near-term obsolescence risk.

Frequently asked questions

Is STM32F303RBT7TR the same as STM32F303RBT7?

The base product number is STM32F303, and the TR suffix on STM32F303RBT7TR indicates Tape & Reel packaging. The non-TR variant (STM32F303RBT7) typically ships in trays or tubes. Electrically and functionally they are identical — the difference is only the shipping medium.

Does STM32F303RBT7TR have DMA and USB?

Yes, the STM32F303RBT7TR includes a DMA controller and a USB interface, as listed in its peripheral and connectivity sets. DMA offloads data movement, and USB enables direct host or device connectivity.
