The 49 GPIOs support a 12-channel 12-bit ADC for analog sensor inputs, and the connectivity set — CAN, I²C, SPI, SSI, UART, IrDA, Microwire — covers most industrial bus interfaces without external transceivers beyond the PHY layer.
Qualifying both variants gives supply-chain flexibility without a PCB change.
The TM4C1230H6PMIR is listed as active.
The only difference is packaging: the 'R' suffix denotes tape-and-reel (TR) and cut tape (CT) options, while the non-'R' variant ships in trays or tubes. The silicon, firmware, and pinout are identical — either can be used interchangeably on the same PCB.
