The STM32L433RCI6TR is an STMicroelectronics STM32L4 series 32-bit ARM Cortex-M4 MCU clocked at 80 MHz.
Housed in a 64-UFBGA (5x5 mm) package, this is a fine-pitch BGA — not a hand-solder part.
For the BOM planner, that means no forced requalification or spot-market scramble in the near term.
The STM32L433RCI6TR is the Tape & Reel (TR) shipping option of the same die and package as the STM32L433RCI6. Electrically and mechanically identical — the suffix only changes the delivery format for pick-and-place lines. The TR variant comes on a reel; the non-TR variant typically ships in tray or tube.
The STM32L4 series from STMicroelectronics is manufactured RoHS-compliant by default. No separate RoHS certificate is needed for standard production lots; the part carries the usual green marking.
The core runs at 80 MHz. That is the maximum CPU clock; the flash prefetch and ART accelerator keep it fed without wait-state penalties at that speed.
