DMA, I²S, POR, PWM, and WDT peripherals are integrated, reducing external glue logic.
STMicroelectronics lists the STM32F071CBU7TR as Active.
For rework, the exposed pad needs a good solder joint for both thermal and electrical connection — a hot-air profile with bottom-side preheat helps avoid tombstoning the small QFN.
The only difference is the packaging format. STM32F071CBU7TR ships in Tape & Reel (TR) for automated assembly lines, while STM32F071CBU7 typically ships in trays or tubes. The silicon, firmware, and electrical specs are identical.
