The TM4C1231E6PZI7 is a Texas Instruments Tiva™ C series 32-bit ARM Cortex-M4F microcontroller running at 80 MHz. The hardware floating-point unit on the M4F core handles sensor fusion, PID math, and FFTs without software emulation overhead — a real advantage over a plain M3 or M0 in motor-drive or instrumentation firmware.
Industrial temperature and connectivity
The 69 GPIOs break out to CAN, I2C, SPI, SSI, UART, and IrDA — enough for a multi-axis drive with encoder feedback and a fieldbus gateway. The 100-LQFP (14x14 mm) is a standard rework-friendly footprint; verify your PCB land pattern matches the supplier package drawing before layout.
Lifecycle status — plan your BOM now
The TM4C1231E6PZI7 has an end-of-life hot status. The manufacturer's last-time-buy window is closing or closed.
What the 80 MHz and 22-channel ADC mean for the BOM
The 80 MHz core speed and 22-channel 12-bit ADC let this MCU sample multiple analog signals (current, voltage, temperature) in a single scan cycle without an external multiplexer. For a motor-drive BOM, that saves a separate ADC chip and the associated isolation — the on-chip ADC and DMA engine handle the data stream. The 2 KB EEPROM emulation space stores calibration constants and fault logs without wearing the Flash.
