The 49 available GPIOs and the 12-channel 12-bit ADC give it the I/O count for a sensor-fusion node or a motor-control interface without needing an external mux. ## Connectivity and peripherals — what is actually on the silicon That USB port supports both device and host modes, so the part can talk to a thumb drive or a sensor dongle directly. The CAN interface is the real differentiator here — it puts this MCU into automotive body-control and industrial fieldbus roles where a plain UART won't cut it. The internal oscillator means you can bring up the core without an external crystal, though the clock accuracy (±1% typical) matters if the CAN bus timing budget is tight. The DMA engine offloads peripheral-to-memory transfers, which keeps the CPU free for the control loop. ## Package and footprint — what the board sees It ships in a 64-LQFP package with a 10x10 mm body and 0.5 mm pitch, surface-mount only.","metaTitle":"TM4C1232D5PMI Tiva C ARM Cortex-M4F MCU, 80MHz, 64KB Flash","metaDescription":"Texas Instruments TM4C1232D5PMI Tiva C Series 32-bit ARM Cortex-M4F MCU. 80MHz core, 64KB Flash, 24KB SRAM, 2KB EEPROM, USB+CAN, 49 I/O, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"80MHz","Series":"Tiva™ C","Package":"Tray","RAM Size":"24K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"2K x 8","Peripherals":"Brown-out Detect/Reset, DMA, POR, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, SPI, SSI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"49","Core Processor":"ARM® Cortex®-M4F","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 12x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"TM4C1232","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 3.63V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.5900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9a4d4826147504e47a42c835aeadbfbf.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TM4C1232D5PMI/alternatives.json"},"ai":{"faq":[{"question":"Does TM4C1232D5PMI support USB host mode?","answer":"Yes, the USB controller on the TM4C1232D5PMI supports both device and host modes, so it can interface directly with USB peripherals like thumb drives or keyboards without an external host controller."},{"question":"Is TM4C1232D5PMI a direct replacement for TM4C1231?","answer":"The TM4C1232D5PMI and TM4C1231 are both Tiva C Series parts in the same 64-LQFP footprint, but the exact pin compatibility and feature set differences should be verified against the respective datasheets.
