The connectivity set includes a 10/100 Ethernet MAC+PHY, USB 2.0 OTG (host and device), two CAN 2.0B controllers, and multiple serial interfaces (UART, I²C, SPI, SSI, IrDA, QEI). This makes the part a natural fit for industrial gateways, programmable logic controllers, building automation controllers, and medical equipment that bridge sensor networks to an Ethernet backbone. The 212-NFBGA (10x10 mm) package delivers 140 GPIOs in a compact footprint, but the 0.5 mm ball pitch demands careful PCB routing and a controlled reflow profile. ## Memory map and peripheral headroom The 1 MB program Flash is organized for efficient firmware OTA updates — the 256 KB SRAM can buffer a new image while the current one runs. The 6 KB EEPROM is separate from the Flash array, so configuration data survives reprogramming without needing a dedicated sector. The 24-channel 12-bit ADC covers multi-sensor analog front ends without external muxing. The brown-out detect and POR eliminate external supervisor ICs in cost-sensitive designs. For new designs, the Tiva C family has broad second-source compatibility across the TM4C129x series, but verify pin compatibility at the specific package variant.","metaTitle":"TM4C129CNCZADI3R Tiva C MCU, ARM Cortex-M4F, 120 MHz","metaDescription":"Texas Instruments TM4C129CNCZADI3R 32-bit ARM Cortex-M4F MCU, 120 MHz, 1 MB Flash, 256 KB SRAM, 6 KB EEPROM, Ethernet, USB OTG, 212-NFBGA, -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":"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":"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":"$11.2518","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/039f2351fd445e4c2d9dc857ea28ed49.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TM4C129CNCZADI3R/alternatives.json"},"ai":{"faq":[{"question":"Is TM4C129CNCZADI3R active or obsolete?","answer":"Active.
