The 105 general-purpose I/O pins and 24-channel 12-bit ADC give it the I/O count and analog front-end for multi-sensor industrial control panels, motor drives, and human-machine interfaces. ## 80 MHz Cortex-M4F — what the core speed buys you The 80 MHz ARM Cortex-M4F with single-cycle DSP instructions and a hardware FPU handles real-time control loops — PID, sensor fusion, FOC for brushless DC motors — without a separate DSP coprocessor. The floating-point unit accelerates trigonometric and matrix math for encoder interpolation and coordinate transforms. For protocol stacks, the 80 MHz clock keeps CAN and USB packet processing within the interrupt service time budget, leaving headroom for the application loop. ## Memory sizing for firmware and data buffers 256 KB Flash and 32K x 8 SRAM support a single firmware image with a bootloader and RTOS. The 2K x 8 EEPROM stores calibration data that survives firmware updates. Supply voltage spans 1.08 V to 3.63 V, with on-chip brown-out detect and POR.","metaTitle":"TM4C1233H6PGEIR Tiva C ARM Cortex-M4F MCU, 80MHz, 256KB Flash","metaDescription":"Texas Instruments TM4C1233H6PGEIR 32-bit ARM Cortex-M4F MCU, 80MHz, 256KB Flash, 32Kx8 RAM, 105 I/O, CAN/USB, -40°C to 85°C.
