That clock rate, combined with the 1 MB on-chip Flash and 256 KB SRAM, puts it in the performance tier for industrial control loops, Ethernet packet processing, and real-time sensor fusion where you need both DSP extensions and hardware divide without cycle-counting. The 120 MHz core speed means the part can sustain a TCP/IP stack, a USB host stack, and a control loop on the same silicon without external RAM for moderate workloads. The 256 KB SRAM is enough for two full Ethernet jumbo frames plus a 320x240 frame buffer, so display and connectivity can coexist. ## Peripheral set — Ethernet, CAN, USB OTG, and 140 GPIO Brown-out detect and POR are integrated, reducing external supervisor IC count. ## 212-NFBGA package — what the 10x10 mm footprint means for the board It remains suitable for new production designs and multi-year BOM commitments.","metaTitle":"Texas Instruments TM4C129XNCZADI3R Tiva C ARM Cortex-M4F MCU","metaDescription":"TI Tiva C TM4C129XNCZADI3R 32-bit ARM Cortex-M4F MCU with 1MB Flash, 256KB SRAM, Ethernet, CAN, USB OTG in 212-NFBGA.","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); Cut Tape (CT)","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":"140","Core Processor":"ARM® Cortex®-M4F","Package / Case":"212-VFBGA","Product Status":"Active","Data Converters":"A/D 24x12b","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":"212-NFBGA (10x10)","Voltage - Supply (Vcc/Vdd)":"2.97V ~ 3.63V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$23.8100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/16a2ea903907422bb7aac7a14bb4daf1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TM4C129XNCZADI3R/alternatives.json"},"ai":{"faq":[{"question":"What is the core processor of TM4C129XNCZADI3R?","answer":"The core processor is an ARM® Cortex®-M4F with single-precision floating-point unit, running at 120 MHz as a 32-bit single-core device."},{"question":"Does TM4C129XNCZADI3R support Ethernet?","answer":"Yes, the connectivity block includes an integrated Ethernet MAC+PHY controller alongside CANbus, USB OTG, and multiple serial interfaces."},{"question":"What is the RAM and Flash size of TM4C129XNCZADI3R?","answer":"It has 1 MB (1M x 8) of program Flash memory and 256 KB (256K x 8) of SRAM, plus 6 KB of EEPROM."},{"question":"What are the key differences between TM4C129XNCZADI3R and TM4C1294NCPDT?","answer":"The TM4C129XNCZADI3R is the higher-density variant in the Tiva C family with 1 MB Flash and 256 KB SRAM versus the TM4C1294NCPDT's 1 MB Flash and 256 KB SRAM — the primary difference is the package: the XNCZADI3R comes in a 212-ball NFBGA (10x10 mm) while the NCPDT is in a 128-pin TQFP.
