FAQ

What is the maximum operating frequency of the TM4C1290NCPDTI3R?

The TM4C1290NCPDTI3R operates at a maximum system clock frequency of 120 MHz, derived from its internal PLL with support for multiple clock sources including external crystals, internal oscillators, or USB SOF clock. This frequency enables real-time execution of complex control algorithms and protocol stacks while maintaining sub-200 ns interrupt latency - a key requirement for the TM4C1290NCPDTI3R in time-critical industrial applications.

Does the TM4C1290NCPDTI3R include an integrated Ethernet physical layer (PHY)?

Yes, the TM4C1290NCPDTI3R integrates a full 10/100 Mbps Ethernet PHY alongside the MAC, supporting RMII interface with dedicated pins for TX, RX, and clock signals. This eliminates the need for an external PHY IC, associated magnetics, and related layout constraints - a defining feature of the TM4C1290NCPDTI3R that reduces system cost and improves signal integrity in compact industrial designs.

What power modes does the TM4C1290NCPDTI3R support, and what is its lowest hibernate current?

The TM4C1290NCPDTI3R supports multiple low-power modes including sleep, deep-sleep, and hibernate. In hibernate mode with RTC active and 2 KB RAM retained, it draws just 1.7 µA - verified per TI's SPMS429B datasheet. This ultra-low current enables decade-long operation on coin-cell batteries, making the TM4C1290NCPDTI3R ideal for remote sensors and battery-backed infrastructure monitoring.

Can the TM4C1290NCPDTI3R execute floating-point operations in hardware?

Yes, the TM4C1290NCPDTI3R incorporates a single-precision ARM Cortex-M4F Floating-Point Unit (FPU) that executes IEEE 754-compliant operations in hardware. This accelerates mathematical computations such as sine/cosine, square root, and matrix transforms by up to 10× compared to software emulation - a critical capability for the TM4C1290NCPDTI3R in motor control, sensor fusion, and real-time signal processing applications.

What is the package type and pin count of the TM4C1290NCPDTI3R?

The TM4C1290NCPDTI3R is packaged in a 128-pin LQFP (Low-Profile Quad Flat Package) measuring 14 mm × 14 mm with 0.4 mm pitch. This package provides full access to all peripherals - including dual CAN, Ethernet, USB, multiple UARTs, and EPI - while remaining compatible with standard surface-mount assembly processes and manual prototyping workflows.
