It carries 256 KB of Flash program memory and 32K x 8 of SRAM, plus 2K x 8 of EEPROM for non-volatile parameter storage. With 69 GPIOs, a 22-channel 12-bit ADC, and a CANbus interface alongside I2C, SPI, UART/USART, and SSI, this MCU is built for industrial control, motor-drive feedback, and sensor-fusion nodes that need deterministic response and moderate code space. ## 80 MHz Cortex-M4F with FPU — what the core speed buys The 80 MHz Cortex-M4F with single-cycle multiply-accumulate and hardware divide handles real-time control loops and FFT-based signal analysis without a separate DSP. The FPU offloads floating-point math for sensor calibration and PID updates, keeping the interrupt latency tight for CANbus or SPI-driven actuator commands. The 100-LQFP (14x14 mm) footprint is a common mid-density package; 69 I/Os give room for a parallel LCD bus, multiple encoder channels, and a CAN transceiver without external muxing.","metaTitle":"TM4C1231H6PZI Tiva C MCU, 80MHz ARM Cortex-M4F, 256KB Flash, 100-LQFP","metaDescription":"TM4C1231H6PZI Tiva™ C 32-bit MCU, 80MHz ARM Cortex-M4F with FPU, 256KB Flash, 32K x 8 RAM, industrial temp -40°C to 85°C, EOL.
