The single-precision FPU on the Cortex-M4F core handles real-time math — PID loops, sensor fusion, or FFT — without a separate DSP. 256 KB of Flash and 32 KB of RAM give it room for a moderate control stack plus a bootloader. The 2 KB EEPROM stores calibration constants or fault logs without wearing the Flash. Connectivity covers CANbus for industrial or automotive networks, USB OTG for device/host switching, and multiple serial interfaces (UART, SPI, I²C, SSI, Microwire, IrDA). The 12-bit ADC with 12 channels handles analog feedback from sensors or current shunts. Rated for -40°C to 85°C ambient, the TM4C123GH6PMIR fits factory-floor controllers, outdoor telecom gear, and engine-bay modules. The 64-LQFP package (10x10 mm) is a common footprint for mid-density MCUs; the 43 I/O are enough for a keypad, display, and a few encoder inputs without needing a port expander.","metaTitle":"TI TM4C123GH6PMIR Tiva C ARM Cortex-M4F MCU, 80 MHz, 256 KB Flash","metaDescription":"Texas Instruments TM4C123GH6PMIR Tiva C series 32-bit ARM Cortex-M4F MCU. 80 MHz, 256 KB Flash, 32 KB RAM, 2 KB EEPROM, industrial temp -40°C to 85°C.
