FAQ

What is the maximum operating frequency of the TM4C123GE6PZT7R?

The TM4C123GE6PZT7R operates at a maximum system clock frequency of 80 MHz, achieved using its internal PLL with an external 1–25 MHz crystal or precision internal RC oscillator. This frequency is sustained across the full industrial temperature range (–40°C to +105°C) and supports deterministic real-time execution of control algorithms without throttling.

Does the TM4C123GE6PZT7R include a hardware floating-point unit?

Yes, the TM4C123GE6PZT7R integrates a full IEEE 754-compliant single-precision floating-point unit (FPU) as part of its ARM Cortex-M4F core. This enables efficient execution of math-intensive operations such as trigonometric functions, matrix multiplication, and PID tuning - critical for motor control and sensor fusion in the TM4C123GE6PZT7R.

How does hibernation mode function on the TM4C123GE6PZT7R?

The TM4C123GE6PZT7R supports hibernation mode with sub-1 µA current draw, retaining RTC timekeeping and 2 KB of battery-backed RAM. Wake-up sources include external interrupts, RTC match events, or GPIO transitions. This capability is implemented in dedicated silicon (HIB module) and requires no external components - a key differentiator of the TM4C123GE6PZT7R.

Is USB functionality self-contained on the TM4C123GE6PZT7R?

Yes, the TM4C123GE6PZT7R includes a full-speed USB 2.0 device controller with integrated physical layer (PHY), eliminating the need for external transceivers. It supports standard device classes including CDC, HID, and MSC out of the box using TI's TivaWare driver library - a core feature distinguishing the TM4C123GE6PZT7R from many competing MCUs.

What analog peripherals are integrated into the TM4C123GE6PZT7R?

The TM4C123GE6PZT7R integrates a 12-bit, 12-channel, 1 MSPS analog-to-digital converter (ADC) with hardware sample averaging and sequencers; an internal temperature sensor; and analog comparators. These are directly accessible via dedicated GPIO pins (e.g., PE0–PE5, PD0–PD7) and require no external signal conditioning for basic sensor interfacing - a defining capability of the TM4C123GE6PZT7R.
