The STM32F105RBT6TR includes two CAN 2.0B interfaces and a USB OTG controller that can operate as host or device. This dual-interface capability is the key differentiator versus the STM32F103 series, which has only USB device and a single CAN."},{"question":"What is the difference between STM32F105RBT6TR and STM32F105RBT6?","answer":"The electrical and mechanical specifications are identical. The TR suffix indicates Tape & Reel packaging for automated pick-and-place, while the base part number (STM32F105RBT6) typically ships in trays or tubes. The die, firmware, and performance are the same."},{"question":"Is STM32F105RBT6TR compatible with STM32F103?","answer":"The STM32F105RBT6TR shares the same ARM Cortex-M3 core, 72 MHz speed, and 64-LQFP footprint as many STM32F103 variants. However, the F105 adds USB OTG and dual CAN, which the F103 lacks. Pin compatibility is not guaranteed across all F103 package options — verify the specific F103 pinout against your PCB layout before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F105RBT6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F105RBT6TR when reusing this data.
