The peripheral set includes CAN, USB, I²C, SPI, SSI, UART, and IrDA — enough serial bandwidth to bridge a Modbus RTU fieldbus to a USB host or daisy-chain multiple drives over CAN.
Supply voltage spans 1.08 V to 3.63 V. The built-in POR, brown-out detect, and watchdog reset the core on power-up. Internal oscillator saves a crystal for UART timing.
The supply voltage range for TM4C1232H6PMI7 is 1.08 V to 3.63 V. This covers both 1.2 V core and 3.3 V I/O rail operation from a single supply.
The TM4C1232H6PMI7 is the same base product (TM4C1232) in a different ordering code variant. The 'I7' suffix indicates the industrial temperature range (-40°C to 85°C) and 64-LQFP package. It is pin-compatible with other TM4C1232H6PMI variants sharing the same package and footprint.
Yes, the TM4C1232H6PMI7 includes a factory-programmed bootloader in ROM that supports UART, I²C, SPI, and CAN serial update protocols. It does not consume Flash space — the bootloader lives in a dedicated ROM region, so the full 256 KB Flash is available for firmware.
