Texas Instruments XM4C1292NCPDTI2

Overview

XM4C1292NCPDTI2 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 deterministic real-time control and wired connectivity.

For engineers reviewing the XM4C1292NCPDTI2 datasheet, XM4C1292NCPDTI2 pinout, XM4C1292NCPDTI2 application, or XM4C1292NCPDTI2 equivalent, key selection criteria include Ethernet PHY integration, on-chip FPU support for sensor fusion math, and hibernation-mode current of 1.7 µA with RTC retention - critical for always-on edge nodes with battery backup.

Technical Context

The XM4C1292NCPDTI2 implements a full-featured Cortex-M4F core with hardware floating-point unit (IEEE 754 single-precision), memory protection unit (MPU), and NVIC supporting up to 128 interrupt lines. It integrates a dedicated 10/100 Ethernet MAC with integrated PHY compliant with IEEE 802.3u, eliminating external magnetics in many designs.

System-level peripherals include dual CAN 2.0B controllers with message RAM and filtering, USB 2.0 OTG with internal transceiver, and a hibernation module with battery-backed RTC, tamper detection, and 2 KB of hibernate memory - enabling low-power wake-up from deep sleep without external components.

FAQ

Does XM4C1292NCPDTI2 include an integrated Ethernet PHY?

Yes, XM4C1292NCPDTI2 integrates a fully compliant IEEE 802.3u 10/100 Ethernet PHY with RMII interface. This eliminates the need for an external PHY chip, magnetics, and associated ESD protection components - reducing bill-of-materials cost and PCB area while simplifying signal integrity validation. The PHY supports auto-negotiation and full-duplex operation.

What is the hibernate current consumption of XM4C1292NCPDTI2?

XM4C1292NCPDTI2 achieves 1.7 µA hibernate current with the real-time clock (RTC) running and 2 KB of SRAM retained. This specification is measured under typical conditions (VDD = 3.3 V, T_A = 25°C) and enables multi-year operation on coin-cell batteries in remote monitoring applications. The hibernation module also supports tamper detection and battery-backed memory.

Is XM4C1292NCPDTI2 pin-compatible with other TM4C129x variants?

XM4C1292NCPDTI2 is pin-compatible with XM4C1294NCPDTI2 and XM4C1297NCPDTI2 in the same 128-pin LQFP package. All share identical pin functions for power, reset, JTAG, Ethernet RMII, USB, CAN, and GPIO. Differences lie in on-die peripherals (e.g., ADC channel count, SRAM size), not pin mapping - enabling drop-in upgrades where enhanced analog or memory resources are required.

Does XM4C1292NCPDTI2 support USB On-The-Go (OTG)?

Yes, XM4C1292NCPDTI2 supports USB 2.0 On-The-Go via its integrated USB controller and on-chip transceiver. It can operate in device, host, or OTG mode without external PHY components. The controller supports up to 12 endpoints, high-bandwidth isochronous transfers, and session request protocol (SRP) for host negotiation - enabling firmware updates via USB stick or connection to PC-based configuration tools.

What debug interface does XM4C1292NCPDTI2 provide?

XM4C1292NCPDTI2 provides a 4-pin SWD (Serial Wire Debug) interface compliant with ARM CoreSight standards, supporting full JTAG/SWD debugging, flash programming, and real-time trace via the TPIU. It is compatible with TI's XDS110 and third-party debug probes (e.g., Segger J-Link). No external debug adapter is required beyond standard SWD cabling and a debug host toolchain.
