1. Describe

Tiva™ C-Series ARM Cortex-M4 microcontrollers provide top performance and advanced integration. For applications requiring extreme power savings, the TM4C123GE6PZ microcontroller features a battery-backed hibernation module that effectively powers down the TM4C123GE6PZ to a low-power state during extended periods of inactivity. Combined with a power-up/power-down sequencer, real-time counter (RTC), multiple sleep-wake options, and dedicated battery-backed memory, the sleep module perfectly positions the TM4C123GE6PZ microcontroller for battery-powered applications. In addition, the TM4C123GE6PZ microcontroller benefits from ARM's widely available development tools, system-on-chip (SoC) infrastructure IP applications and large user community. In addition, microcontrollers use ARM's Thumb®-compatible Thumb-2 instruction set to reduce memory requirements, thereby reducing cost. Finally, most of the TM4C123GE6PZ microcontroller code is compatible with the Tiva™ C Series product line, providing flexibility across designs.

2. ARM Cortex-M4F processor core

All members of the Tiva™ C family, including the TM4C123GE6PZ microcontroller, are designed around the ARM Cortex-M processor core. The ARM Cortex-M processor provides the core for a high- performance, low-cost platform that addresses the need for minimal memory implementation, reduced pin count, and low power consumption, while delivering outstanding computing performance and excellent system responsiveness to interrupts.
