The 256 KB Flash holds a full Modbus TCP stack plus a bootloader partition; the 32 KB RAM supports moderate data buffers and a FreeRTOS heap. 2 KB EEPROM stores calibration constants and node IDs without external serial memory. The peripheral set includes CAN, I²C, SPI, UART, SSI, and IrDA — enough to bridge a CANopen fieldbus to a UART-based sensor array without an external protocol converter. ## 69 GPIOs and 22-channel 12-bit ADC","metaTitle":"Texas Instruments TM4C1231H6PZIR Tiva C MCU, 80 MHz, 256 KB Flash","metaDescription":"Texas Instruments TM4C1231H6PZIR 32-bit ARM Cortex-M4F MCU, 80 MHz, 256 KB Flash, 32 KB RAM, 2 KB EEPROM, industrial temp -40 to 85°C.
