Product details
Overview
TM4C1294KCPDTI3R from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 120 MHz operation, 1 MB Flash, 256 KB SRAM, integrated Ethernet MAC+PHY, USB 2.0 OTG, and dual CAN controllers - deployed in industrial gateways requiring real-time protocol bridging and secure connectivity.
For engineers reviewing the TM4C1294KCPDTI3R datasheet, TM4C1294KCPDTI3R pinout, TM4C1294KCPDTI3R application, or TM4C1294KCPDTI3R equivalent, key selection criteria include integrated Ethernet PHY support, deterministic real-time interrupt latency (<12 cycles), FPU-enabled floating-point math for motor control, and TivaWare™ software stack compatibility.
Technical Context
The TM4C1294KCPDTI3R implements a single-core ARM Cortex-M4F processor with hardware floating-point unit (FPU), memory protection unit (MPU), and NVIC supporting up to 128 interrupt lines. It integrates a full-speed USB 2.0 OTG controller with internal transceiver and dedicated DMA channels.
Its system-level integration includes a 10/100 Ethernet MAC with integrated IEEE 802.3-compliant PHY, two CAN 2.0B controllers, and a 16-bit external peripheral interface (EPI) supporting SDRAM, NOR, and NAND flash - enabling direct connection to external memory without external glue logic.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F767ZIT6 | No integrated Ethernet PHY; requires external PHY; higher core clock (216 MHz) but lacks on-chip USB transceiver. | Better suited for high-throughput image processing; less optimal for compact Ethernet gateway designs due to added PHY BOM and layout complexity. | Select when FPU performance >1.5 GFLOPS is required and external PHY integration is acceptable. |
| MSP432P401RIPZT | Lower clock (48 MHz), no Ethernet PHY, no CAN, smaller Flash (2 MB) - ARM Cortex-M4F with ultra-low-power focus. | Targeted at battery-powered sensor nodes; lacks real-time networking features needed for industrial gateway use cases. | Select only for low-power, non-networked embedded control where Ethernet/CAN are unnecessary. |
Compared with STM32F767ZIT6 and MSP432P401RIPZT, TM4C1294KCPDTI3R uniquely combines integrated Ethernet PHY, dual CAN, USB OTG transceiver, and industrial temperature rating in a single LQFP package - minimizing system-level design effort for protocol-aware edge controllers.

FAQ
What is the maximum operating frequency of the TM4C1294KCPDTI3R?
The TM4C1294KCPDTI3R operates at a maximum system clock frequency of 120 MHz, derived from its internal PLL with support for multiple clock sources including external crystal (1–25 MHz), internal RC oscillator, or precision internal oscillator (PIOSC). This frequency enables real-time execution of protocol stacks such as EtherNet/IP and Modbus TCP with guaranteed latency under 15 µs for Ethernet frame processing in the TM4C1294KCPDTI3R.

Yes, the TM4C1294KCPDTI3R includes a fully integrated IEEE 802.3-compliant 10/100 Ethernet PHY with MII/RMII interface support. This eliminates the need for an external PHY IC, reduces BOM cost, simplifies PCB layout, and improves signal integrity by removing external differential trace routing. The TM4C1294KCPDTI3R PHY supports auto-negotiation, MDIO/MDC management, and full-duplex operation - all verified per TI SPMS445B datasheet section 11.3.
What development tools and software support are available for the TM4C1294KCPDTI3R?
Texas Instruments provides TivaWare™ Peripheral Driver Library, Code Composer Studio IDE, and TI-RTOS kernel support for the TM4C1294KCPDTI3R.

What is the temperature range specification for the TM4C1294KCPDTI3R?
The TM4C1294KCPDTI3R is rated for operation from –40°C to +105°C ambient temperature, meeting extended industrial requirements. This range is validated per TI's production test flow and documented in the SPMS445B datasheet section 1.3.10. The device maintains full functionality - including Ethernet PHY timing, USB transceiver compliance, and Flash programming - across this entire range, making it suitable for deployment in uncontrolled environments like factory floors or outdoor utility enclosures.
How does the TM4C1294KCPDTI3R handle power management in low-power applications?
The TM4C1294KCPDTI3R implements six low-power modes (Sleep, Deep-Sleep, Hibernate, etc.) with sub-1 µA Hibernate current when RTC and battery-backed RAM are active. Wake-up sources include Ethernet magic packet, CAN bus activity, GPIO, and RTC alarm - all configurable without CPU intervention. In Hibernate mode, the TM4C1294KCPDTI3R retains full register state and executes wake-up ISR within 1.2 µs, enabling rapid response in battery-constrained edge nodes.
