Product details

72 MHz Cortex-M4 with FPU — built for real-time control

The STM32F334K8T6TR: The 32-LQFP (7x7 mm) package exposes 25 I/O, including a 9-channel 12-bit ADC and a 3-channel 12-bit DAC for analog signal chain integration.

Industrial temperature range and CANbus — where it fits

The on-chip CANbus peripheral (2.0B active) ties directly into industrial fieldbus networks without an external transceiver.

For production planning, this means the part remains in full manufacturing and can be specified into new BOMs without obsolescence contingency. ROHS3 compliant as shipped.

Frequently asked questions

Can STM32F334K8T6TR be used for BLDC motor control?

Yes, the 72 MHz Cortex-M4 with FPU, combined with the 9-channel 12-bit ADC and 3-channel 12-bit DAC, supports the sensor feedback and PWM generation needed for field-oriented control of BLDC motors. The CANbus interface also fits into industrial drive networks.
