If your application needs over-the-air updates or a complex state machine, the same footprint is shared by higher-density siblings in the STM32F301 line — worth qualifying before the layout locks. ## Industrial temperature range and 24 I/O The 24 I/O lines, combined with the internal oscillator and peripherals (DMA, I²S, POR, PWM, WDT), let this MCU handle a sensor-fusion or brushless-DC motor controller with a single chip, no external clock or supervisor needed. ## Data converters and connectivity The connectivity set — I²C, SPI, UART/USART, LIN, and IrDA — covers the common industrial serial buses. The 72 MHz core with FPU can run a PID loop or a sensor-fusion algorithm in single-precision math without a separate DSP. ## Package and mounting note","metaTitle":"STM32F301K6U7TR STM32F3 ARM Cortex-M4 MCU, 72 MHz","metaDescription":"STM32F301K6U7TR is a 32-bit ARM Cortex-M4 MCU from STMicroelectronics, 72 MHz, 32 KB Flash, 16 KB SRAM, 24 I/O, -40 to 105°C.

The SWD interface is available on the 32-UFQFN package for programming and debugging. The internal oscillator means no external clock is needed for bring-up."},{"question":"Is STM32F301K6U7TR RoHS compliant?","answer":"The STM32F301K6U7TR is a current-production part from STMicroelectronics and is manufactured RoHS-compliant (lead-free) as standard for the STM32F3 series.
