FAQ
What is the maximum operating frequency of the TM4C1299NCZADT3?
The TM4C1299NCZADT3 operates at a maximum CPU frequency of 120 MHz, sustained across its full industrial temperature range (–40°C to +105°C). This speed is achieved using the on-chip PLL with external crystal or oscillator input, and is validated per TI's production test flow. The TM4C1299NCZADT3 maintains consistent timing margins for all peripherals-including Ethernet MAC, USB, and EPI-at this frequency.
Does the TM4C1299NCZADT3 include an integrated Ethernet physical layer (PHY)?
Yes, the TM4C1299NCZADT3 integrates a full 10/100 Mbps Ethernet PHY compliant with IEEE 802.3u, including RMII interface, auto-negotiation, and MDIO management. No external PHY IC or companion magnetics IC is required - only a standard Ethernet transformer and passive components per TI's reference design SLAU595. This integration reduces bill-of-materials cost and PCB footprint versus PHY-less alternatives like the TM4C1294NCPDT3.
What memory resources are available on the TM4C1299NCZADT3?
The TM4C1299NCZADT3 provides 1 MB of on-chip Flash memory for program storage, 256 KB of SRAM for runtime data and stack, and 6 KB of EEPROM for nonvolatile parameter storage. All memory blocks are accessible via the 32-bit bus matrix with zero-wait-state operation at 120 MHz. Flash supports secure locking, erase granularity down to 1 KB sectors, and error correction coding (ECC) for enhanced reliability in industrial deployments.
Can the TM4C1299NCZADT3 operate in low-power hibernation mode with real-time clock functionality?
Yes, the TM4C1299NCZADT3 includes a dedicated hibernation module that supports RTC operation with battery backup, tamper-detection inputs, and retention of critical registers while drawing less than 2 µA. The hibernation module maintains timekeeping accuracy to ±10 ppm over temperature and supports wake events from RTC match, external pins, or tamper conditions - making it suitable for energy metering and battery-powered industrial sensors.
What development tools and software support are available for the TM4C1299NCZADT3?
Texas Instruments provides full support for the TM4C1299NCZADT3 through TivaWare™ C Series Software, Code Composer Studio™ IDE, and the EK-TM4C1294XL LaunchPad™ development kit. TivaWare includes peripheral drivers, USB stack, Ethernet stack (with lwIP), and FreeRTOS port. TI also offers application-specific examples - such as Ethernet gateway reference designs and CAN-to-USB bridges - all validated on the TM4C1299NCZADT3 silicon.
