Hardware Description
The Crypto Connected LaunchPad includes a TM4C129ENCPDT microcontroller with an integrated
10/100 Ethernet MAC and PHY and crypto acceleration blocks. 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.
Figure 2-1 provides a high-level block diagram of the Crypto Connected LaunchPad.

2.1 Functional Description
2.1.1 Microcontroller
The TM4C129ENCPDT 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 hardware crypto accelerators; 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. For more complete details, see the TM4C129ENCPDT
microcontroller
data sheet .
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 general-
purpose input/output (GPIO) pads. When adding external circuitry, consider the additional load on the
evaluation board power rails.
The TM4C129ENCPDT microcontroller is factory-programmed with an out of the box demo program. The
out of the box program resides in on-chip Flash memory and runs each time power is applied, unless the
out of the box application has been replaced with a user program. The out of the box application
automatically connects to

Ethernet jack on the evaluation board.
