Hardware Description
The Connected LaunchPad includes a TM4C1294NCPDTI microcontroller with an integrated 10/100
Ethernet MAC and PHY. This advanced ARM® Cortex™ M4F MCU has a wide range of peripherals that
are made available to users via the on-board accessories and the BoosterPack connectors. This chapter
explains how those peripherals operate and interface to the microcontroller.

Functional Description
2.1.1 Microcontroller
The TM4C1294NCPDTI is a 32-bit ARM Cortex-M4F based microcontroller with 1024-kB Flash memory,
256-kB SRAM, 6-kB EEPROM, and 120 MHz operation; integrated 10/100 Ethernet MAC and PHY;
integrated USB 2.0 connectivity with external high-speed USB 3.0 PHY capability; a hibernation module, a
multitude of serial connectivity and motion control PWM; as well as a wide range of other peripherals. See
the TM4C1294NCPDTI microcontroller
for more complete details.
Most of the microcontroller’s signals are routed to 0.1-in (2.54-mm) pitch headers or through-hole solder
pads. An internal multiplexor allows different peripheral functions to be assigned to each of these GPIO
pads. When adding external circuitry, consider the additional load on the evaluation board power rails.
The TM4C1294NCPDTI microcontroller is factory-programmed with a quickstart demo program. The
quickstart program resides in on-chip Flash memory and runs each time power is applied, unless the
quickstart application has been replaced with a user program. The quickstart application automatically
connects to
when an internet connection is provided through the RJ45 Ethernet jack
on the evaluation board.
