The 256 KB SRAM is enough for double-buffered Ethernet frames and a moderate data-logging buffer. The 6 KB EEPROM is useful for storing calibration constants and node IDs without wearing the Flash. The 90 GPIOs in the 128-TQFP package give headroom for a parallel LCD interface or a bank of opto-coupled inputs on a motor-drive control card.","metaTitle":"TM4C129DNCPDTT3 Tiva C Cortex-M4F MCU, 120MHz, 1MB Flash","metaDescription":"Texas Instruments TM4C129DNCPDTT3 ARM Cortex-M4F MCU, 120 MHz, 1 MB Flash, 256 KB SRAM, Ethernet, CAN, USB OTG.","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":"Tray","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~105°C(TA)","Supplier Device Package":"128-TQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.97V ~ 3.63V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.3786","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f48acb2b532d7e4473173809d890668f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TM4C129DNCPDTT3/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TM4C129DNCPDTT3 and TM4C129ENCPDTT3?","answer":"The TM4C129ENCPDTT3 is a pin-compatible variant within the same Tiva C family. The primary difference is that the 'E' version adds a cryptographic accelerator (AES, DES, SHA) and a hardware CRC module, while the 'D' version (this part) omits those security blocks. Both share the same 120 MHz Cortex-M4F core, 1 MB Flash, 256 KB SRAM, Ethernet MAC+PHY, and CAN controllers. If your application does not need hardware cryptography, the TM4C129DNCPDTT3 is the cost-optimized choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TM4C129DNCPDTT3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TM4C129DNCPDTT3 when reusing this data.
