Typical applications include industrial control, motor drives, sensor hubs, and CAN-bus gateway nodes where the Cortex-M4F DSP extensions and the integrated 12-bit ADC array (12 channels) handle mixed-signal workloads without an external converter. ## 80 MHz Cortex-M4F — what it buys you The 80 MHz core with single-cycle MAC and hardware divide handles PID loops, Modbus RTU, and CANopen nodes. The FPU processes sensor fusion math in firmware. ## Memory budget — 64 KB Flash, 24 KB SRAM, 2 KB EEPROM 64 KB of Flash supports a bootloader and a moderate application. The 24 KB SRAM leaves room for buffers and stack. The 2 KB EEPROM stores calibration constants.","metaTitle":"Texas Instruments TM4C1231D5PMI7R Tiva C MCU, 80MHz","metaDescription":"TM4C1231D5PMI7R 32-bit ARM Cortex-M4F MCU, 80MHz, 64KB Flash, 24KB SRAM, 43 I/O, -40°C to 85°C.
