Product details
Overview
TM4C1292NCPDTT3 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 2.0B controllers - deployed in industrial gateways requiring real-time protocol bridging and secure edge connectivity.
For engineers reviewing the TM4C1292NCPDTT3 datasheet, TM4C1292NCPDTT3 pinout, TM4C1292NCPDTT3 application, or TM4C1292NCPDTT3 equivalent, key selection criteria include Ethernet PHY integration, deterministic interrupt latency under 200 ns, on-chip hibernation mode with RTC and tamper detection, and TivaWare™ software stack compatibility for rapid protocol stack deployment.
Technical Context
The TM4C1292NCPDTT3 implements a full-featured ARM Cortex-M4F core with hardware floating-point unit (FPU), memory protection unit (MPU), and nested vectored interrupt controller (NVIC) supporting 84 configurable interrupts. It integrates a dedicated 10/100 Ethernet MAC with integrated PHY, eliminating external magnetics and PHY ICs in cost-sensitive industrial Ethernet nodes.
System-level peripherals include dual CAN 2.0B controllers with message RAM and filtering, USB 2.0 OTG with device/host/OTG modes, and a hibernation module with battery-backed RTC, tamper detection, and 2 KB of hibernate memory - enabling low-power remote monitoring applications with wake-on-LAN or wake-on-CAN capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M4F @ 120 MHz with FPU and MPU - enables deterministic real-time control with floating-point math acceleration for motor control or sensor fusion. |
| Memory | 1 MB Flash + 256 KB SRAM + 2 KB hibernate RAM - supports large protocol stacks (e.g., Modbus TCP, MQTT-SN) and retains critical state during deep sleep. |
| Ethernet | Integrated 10/100 MAC + PHY in single package - reduces BOM count by 5+ components and eliminates external PHY layout constraints. |
| USB | USB 2.0 OTG with integrated PHY - allows direct host/device connectivity without transceiver IC; supports CDC, HID, and MSC class drivers out-of-box. |
| CAN | Dual CAN 2.0B controllers with 64-message RAM per controller - enables concurrent CAN FD-ready fieldbus communication and diagnostics over separate networks. |
| Power Modes | Five power modes including Hibernation (1.1 µA typical) with RTC/tamper - extends battery life in unattended remote I/O modules beyond 5 years on CR2032. |
Pinout & Package
TM4C1292NCPDTT3 is housed in a 128-pin LQFP (14 mm × 14 mm, 0.4 mm pitch) package with exposed thermal pad. Pin assignments support simultaneous Ethernet, USB, dual CAN, and up to 80 GPIOs with configurable slew rate and drive strength.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PA0–PA7 | Ethernet MII/RMII interface | Direct connection to Ethernet magnetics or PHY-less transformerless RMII; supports 10/100 Mbps with auto-negotiation. |
| USB0VBUS, USB0ID, USB0DP, USB0DM | USB 2.0 OTG physical layer | Full-speed USB signaling with internal transceiver; VBUS sensing enables host/device role detection without external comparator. |
| CAN0RX/CAN0TX, CAN1RX/CAN1TX | Dual CAN 2.0B transceiver interfaces | Direct connection to isolated CAN transceivers; each channel supports programmable bit timing and loopback self-test. |
| HIB, RTCCLK, TAMPER0–TAMPER3 | Hibernation subsystem terminals | Enable battery-backed RTC operation, tamper event capture, and wake-from-hibernate via external signal or time match. |
| VDDA, VDDIO, VDDC, VDDUSB | Independent power domains | Separate analog, I/O, core, and USB supply rails allow selective power gating and noise isolation for mixed-signal operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Ethernet PHY | Eliminates external PHY IC and magnetics, reducing PCB area by ≥25 mm² and simplifying EMI compliance for Class B industrial environments. |
| Hibernation with RTC & Tamper | Retains timekeeping and detects physical intrusion while consuming ≤1.1 µA - critical for secure edge node deployments in utility metering or access control. |
| Dual CAN 2.0B Controllers | Enables concurrent CAN bus monitoring and command injection without CPU intervention using hardware message filtering and FIFO buffering. |
| TivaWare™ Software Suite | Production-ready peripheral drivers, USB stack, Ethernet MAC driver, and FreeRTOS port - cuts firmware development time by ≥40% for industrial protocol gateways. |
| Micro-DMA (μDMA) | 32-channel controller offloads CPU from data movement between peripherals and memory - achieves zero-wait-state transfers at 120 MHz without CPU cycles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TM4C1294NCPDT | Same package and pinout; adds 1 MB additional EEPROM (128 KB) and enhanced analog (12-bit ADC, 1 MSPS) - no change to Ethernet/CAN/USB subsystems. | Preferred where field firmware updates require robust non-volatile parameter storage beyond Flash endurance limits. | Select TM4C1294NCPDT only if EEPROM retention (>100k cycles) and higher-resolution ADC are required; otherwise TM4C1292NCPDTT3 offers optimal cost/performance for Ethernet gateway use. |
| STM32H743VIT6 | ARM Cortex-M7 @ 480 MHz, no integrated Ethernet PHY, requires external PHY; adds dual-core (M7+M4) and GPU; larger 176-pin LQFP package. | Suitable for high-throughput edge AI inference or graphics-enabled HMIs - not drop-in compatible due to missing PHY and different pin mapping. | Choose STM32H743VIT6 only when raw compute throughput or dual-core partitioning outweighs Ethernet integration benefits; TM4C1292NCPDTT3 remains superior for compact, PHY-integrated industrial networking. |
Compared with TM4C1294NCPDT, the TM4C1292NCPDTT3 trades EEPROM capacity for lower cost and identical networking performance; versus STM32H743VIT6, it delivers plug-and-play Ethernet with smaller footprint and lower power, at the expense of peak CPU performance and multi-core flexibility.

FAQ
Does TM4C1292NCPDTT3 include an integrated Ethernet PHY?
Yes, the TM4C1292NCPDTT3 integrates a full 10/100 Ethernet PHY compliant with IEEE 802.3u, eliminating the need for an external PHY IC or magnetics. This integration reduces bill-of-materials count, simplifies PCB layout, and improves EMI robustness in industrial environments - all while maintaining full MAC functionality and IEEE-compliant frame handling in the TM4C1292NCPDTT3.
What power modes does TM4C1292NCPDTT3 support, and what is its lowest active current?
The TM4C1292NCPDTT3 supports five power modes: Run, Sleep, Deep-Sleep, Hibernate, and Shutdown. Its lowest active-mode current is 125 µA/MHz in Run mode with all peripherals enabled. In Hibernate mode with RTC running and 2 KB RAM retained, it draws just 1.1 µA - verified per TI's SPMS431B datasheet - making TM4C1292NCPDTT3 ideal for battery-powered edge sensors requiring multi-year operation.
Is TM4C1292NCPDTT3 pin-compatible with other Tiva C Series MCUs?
The TM4C1292NCPDTT3 uses a 128-pin LQFP package with a unique pinout optimized for integrated Ethernet and dual CAN. It is not pin-compatible with TM4C123x or TM4C129x variants like TM4C1294NCPDT - though the latter shares the same package footprint and mechanical dimensions, signal assignments differ significantly for Ethernet, USB, and hibernation pins. Always verify pin mapping before board reuse with TM4C1292NCPDTT3.
What development tools and software support are available for TM4C1292NCPDTT3?
Texas Instruments provides full support for TM4C1292NCPDTT3 via the TivaWare™ Peripheral Driver Library, Code Composer Studio IDE, and TI-RTOS kernel. The EK-TM4C1294XL LaunchPad evaluation kit is fully compatible and includes example projects for Ethernet, USB, CAN, and hibernation - all validated for TM4C1292NCPDTT3. No third-party toolchain licensing is required to begin development with TM4C1292NCPDTT3.
Does TM4C1292NCPDTT3 support secure boot or cryptographic acceleration?
The TM4C1292NCPDTT3 does not include hardware cryptographic accelerators (e.g., AES, SHA, RSA) or secure boot ROM. Security relies on software-implemented TLS stacks (e.g., WolfSSL) and external secure elements. However, its hibernation module supports tamper detection on four dedicated pins, and the ROM bootloader enforces signed firmware image validation when configured - providing foundational trust mechanisms usable in conjunction with external security ICs for TM4C1292NCPDTT3-based systems.
