Product details

The TM4C1231H6PMI is a Texas Instruments Tiva C series ARM Cortex-M4F 32-bit MCU running at 80 MHz. That core includes a single-precision floating-point unit, so PID loops, sensor fusion, and filter math execute without software emulation overhead. The 256 KB Flash and 32K x 8 RAM give enough room for a moderate CANopen or Modbus stack plus a real-time control task. 43 I/O lines in a 64-LQFP package keep the board layout dense but routable on a two-layer PCB.

Industrial temperature range — rated for the factory floor

Supply range is 1.08 V to 3.63 V.

Connectivity and peripherals — CAN, I2C, SPI, UART

A 12-channel 12-bit ADC handles analog feedback from current sensors or thermocouple amplifiers.
