Program memory is 1 MB of Flash, backed by 256K x 8 of SRAM and 6K x 8 of EEPROM — the EEPROM is useful for storing calibration constants and configuration parameters without wearing the Flash. The 140 GPIOs in the 212-NFBGA package provide ample interface capacity for parallel displays, external memory buses, and sensor arrays. The connectivity set is what distinguishes this part: Ethernet MAC+PHY, two CAN 2.0 controllers, USB OTG, and multiple UART/USART, I2C, and QSSI (SPI) interfaces. Supply voltage is 2.97 V to 3.63 V, which aligns with standard 3.3 V rail designs. ## 212-NFBGA (10x10) — layout considerations Decoupling should follow the layout guidelines in the Tiva C datasheet — typically a 10 µF bulk cap per supply rail plus 100 nF per VDD pair placed within 3 mm of the ball. The 140 I/O are distributed across the BGA ball map; the Ethernet PHY requires specific analog supply pins that should be isolated from the digital supply with a ferrite bead. ## Peripherals and data conversion On-chip data converters include a 24-channel, 12-bit ADC — enough to sample multiple analog inputs from current sensors, thermistors, or potentiometers without external muxing. The peripheral set includes motion-control PWM, a watchdog timer, brown-out detect, POR, DMA, and a motion-control PWM module, covering the typical needs of motor drive and power conversion applications.","metaTitle":"TI TM4C129ENCZADT3 Tiva C ARM Cortex-M4F MCU, 120MHz","metaDescription":"Texas Instruments TM4C129ENCZADT3 Tiva™ C Series 32-bit ARM Cortex-M4F MCU. 120MHz core, 1MB Flash, 256K RAM, Ethernet+USB+CAN.

The TM4C1294NCPDT offers 512 KB Flash with an integrated PHY in a 128-pin TQFP, while the TM4C129ENCZADT3 carries 1 MB Flash and the full 140 I/O in the 212-NFBGA package. For a lower pin-count design without Ethernet, the TM4C123 series is an option, but it is not pin-compatible."},{"question":"What is TM4C129ENCZADT3's listed speed?","answer":"The core runs at 120 MHz, which is the maximum clock frequency for the Tiva C Series Cortex-M4F. At this speed, the Flash requires one wait state for zero-wait execution; the prefetch buffer helps maintain throughput for sequential code."},{"question":"Is TM4C129ENCZADT3 compatible with existing Tiva C development boards?","answer":"The part is not directly socket-compatible with the DK-TM4C129X development board, which uses a 212-BGA package with a different ball map. However, the TM4C129ENCZADT3 shares the same core, peripheral set, and software ecosystem as the TM4C129XNCZAD part used on that board. Code developed on the DK-TM4C129X can be ported with minimal changes by adjusting the pin mux configuration in the TivaWare driver library."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TM4C129ENCZADT3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TM4C129ENCZADT3 when reusing this data.
