The TM4C1233E6PMIR is a Texas Instruments Tiva C series 32-bit ARM Cortex-M4F microcontroller running at 80 MHz. That core includes a single-precision floating-point unit, so PID loops, sensor fusion math, and filter coefficients stay in hardware rather than soft-emulated. The 128 KB Flash and 32K x 8 RAM give it enough room for a CANopen stack plus a modest HMI page buffer — think pump controllers, conveyor drives, or a local operator panel with a small display. The 43 I/O lines, 12-bit ADC with 12 channels, and CAN, USB, UART, SPI, and I2C interfaces cover the typical fieldbus gateway or multi-sensor aggregator role.
The 128 KB Flash holds a real-time OS kernel, a CANopen or Modbus RTU stack, and application code for a mid-complexity control task. The 32K x 8 RAM supports a few hundred tag-mapped variables and a UART DMA buffer for logging.
Connectivity and peripheral set — CAN, USB, and serial interfaces
The TM4C1233E6PMIR includes CAN, USB, UART, SPI, I2C, SSI, and IrDA interfaces. For a panel builder wiring a drive to a PLC, the CAN port handles the motion bus while the USB device port serves as a local programming and diagnostics access. The 12-bit ADC with 12 channels reads analog sensors directly — pressure transducers, temperature probes, or potentiometer feedback. The internal oscillator saves an external crystal for non-critical timing; keep a crystal for CAN or USB bit-rate accuracy.
Lifecycle and sourcing — EOL hot, last-time-buy window
The TM4C1233E6PMIR has an EOL hot lifecycle stage. The product status is Active.
