The TM4C1231H6PGEI7: For new designs, this provides a stable supply horizon. The base product number TM4C1231 covers a family of density and temperature variants, allowing a pin-compatible migration path within the same footprint if memory or temperature grade requirements change.
The evidence does not list USB OTG among the connectivity interfaces. The listed interfaces are CANbus, I²C, IrDA, Microwire, SPI, SSI, and UART/USART. If USB OTG is required, a different Tiva C variant or an external USB controller would be needed.
