Product details

The 64-LQFP package is a through-hole-friendly surface-mount footprint — you can swap it on site with a decent iron and some flux, no hot-air station required.

The CANbus interface (2.0B active) and USB 2.0 full-speed device controller are both on the same chip, which saves an external transceiver or bridge for many industrial and IoT edge designs.

Runs from 2.0 V to 3.6 V on the Vcc/Vdd rail, so it works with a 3.3 V supply directly and can tolerate a 2.8 V LDO output in battery-backed designs.

No last-time-buy or end-of-life risk for new designs.

Frequently asked questions

Is STM32F302RBT6 compatible with STM32F303?

The STM32F302RBT6 and STM32F303 series share the same 64-LQFP footprint and are pin-compatible, but the F303 adds more advanced timer features and a higher-resolution ADC. For a drop-in replacement with identical memory and speed, the STM32F303RBT6 is the closest sibling.
