The 1 MB Flash and 256K x 8 SRAM give enough room for a full TCP/IP stack, a FreeRTOS or TI-RTOS kernel, and application code for an industrial gateway or a building automation controller. ## Connectivity set — Ethernet, CAN, USB OTG, and 90 I/O This part integrates an Ethernet MAC+PHY, two CAN 2.0 controllers, USB OTG (Host/Device), plus eight UARTs, four SPI/I²C modules, and a QEI for quadrature encoder inputs. That peripheral mix targets exactly the class of designs that need a single-chip controller for a factory-floor gateway: one CAN bus talks to a VFD, the Ethernet port streams telemetry to the cloud, and the USB OTG connects a flash drive for local data logging. The 90 general-purpose I/O, mapped across the 128-TQFP package, leave enough pins for a parallel LCD interface, external memory via the EBI/EMI bus, and a keypad matrix without a port expander. That means it is suitable for new design-ins and production ramp without an obsolescence clock. The 128-TQFP (14x14 mm) with 0.4 mm pitch needs a controlled-impedance PCB stack and solder-mask-defined pads; the MSL rating (typically MSL 3) means a bake before reflow if the moisture-barrier bag has been open past the floor-life window. ## Supply voltage range and on-chip data converters The core and I/O operate from 2.97 V to 3.63 V, which is the standard 3.3 V rail with margin for a linear regulator's dropout. The 20-channel 12-bit ADC samples at up to 2 Msps — enough for three-phase current sensing plus a few auxiliary analog inputs in a motor-drive application.","metaTitle":"TM4C129DNCPDTI3R Tiva C MCU, 120MHz Cortex-M4F, 1MB Flash","metaDescription":"TM4C129DNCPDTI3R Tiva C ARM Cortex-M4F MCU: 120MHz, 1MB Flash, 256KB SRAM, Ethernet+USB+CAN, 90 I/O, -40C to 85C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"120MHz","Series":"Tiva™ C","Package":"Tape & Reel (TR)","RAM Size":"256K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"6K x 8","Peripherals":"Brown-out Detect/Reset, DMA, Motion Control PWM, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"90","Core Processor":"ARM® Cortex®-M4F","Package / Case":"128-TQFP","Product Status":"Active","Data Converters":"A/D 20x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"TM4C129","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"128-TQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.97V ~ 3.63V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.4105","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f48acb2b532d7e4473173809d890668f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TM4C129DNCPDTI3R/alternatives.json"},"ai":{"faq":[{"question":"Is TM4C129DNCPDTI3R still active or nearing end of life?","answer":"TM4C129DNCPDTI3R carries an Active lifecycle status."},{"question":"What are the direct alternatives or replacements for TM4C129DNCPDTI3R?","answer":"Within the Tiva C TM4C129 family, the TM4C129DNCPDTI3 (without the 'R' suffix) is functionally identical but ships in a tray instead of Tape & Reel.
