The microcontrollers feature integrated communication peripherals alongwith other high-performance analog and digital functions to offer a strong foundation for manydifferent target uses, spanning from human machine interface to networked system managementcontrollers.In addition, Tiva C Series microcontrollers offer the advantages of ARM"s widely availabledevelopment tools, System-on-Chip (SoC) infrastructure, and a large user community. Additionally,these microcontrollers use ARM"s Thumb®-compatible Thumb-2 instruction set to reduce memoryrequirements and, thereby, cost. Finally, the TM4C1294KCPDT microcontroller is code-compatibleto all members of the extensive Tiva C Series, providing flexibility to fit precise needs.
