The STM32F107RBT6: Integrated Ethernet MAC, CAN 2.0B, and USB OTG FS in the 64-LQFP package with 51 GPIOs.
72 MHz maximum clock from the internal oscillator or external crystal.
64-LQFP package.
Yes — the STM32F107RBT6 integrates an Ethernet MAC peripheral alongside CAN, USB OTG, I²C, SPI, and multiple UART/USART interfaces.
The STM32F107RCT6 is the higher-density variant in the same family: it doubles the Flash to 256 KB and the SRAM to 64 KB (versus 128 KB Flash and 64 KB SRAM on the RBT6). Both share the same 64-LQFP package, pinout, and peripheral set — the RCT6 is the drop-in upgrade when firmware size exceeds the 128 KB budget.
