The microcontroller contains a fully integrated Ethernet MAC and PHY. This integration creates a simple, elegant and cost-saving Ethernet circuit design. Example code is available for both the uIP and LwIP TCP/IP protocol stacks. The embedded Ethernet on this device can be programmed to act as an HTTP server, client or both. The design and integration of the circuit and microcontroller also enable users to synchronize events over the network using the IEEE1588 precision time protocol. When configured for an Ethernet operation, it is recommended that the user configure LED D3 and D4 to be controlled by the Ethernet MAC to indicate connection and transmit/receive status. 2.1.3 Crypto Accelerators The Crypto Connected LaunchPad features the hardware acceleration blocks such as Advanced Encryption Standard (AES), Data Encryption Standard (DES), and Secure Hash Algorithm/MD5 Message Digest Algorithm (SHA/MD5) that offload data encryption and decryption functions from CPU. These hardware cipher blocks support the µDMA operation and have improved performance over software cipher blocks. The AES block is a symmetric cipher module that supports multiple encrypt and decrypt operations, feedback operating modes, authentication modes, key sizes (128 bit, 192 bit, or 256 bit) and key scheduling in hardware. The DES block is also a symmetric cipher module with DES/3DES encryption and decryption along with support for multiple feedback operating modes. The SHA/MD5 block is a hash module that can run functions like MD5, SHA-1, SHA224, SHA256 and Hash message authentication code (HMAC). 2.1.4 USB Connectivity The Crypto Connected LaunchPad is designed to be USB 2.0 ready. A TPS2052B load switch is connected to and controlled by the microcontroller USB peripheral, which manages power to the USB micro A/B connector when functioning in a USB host. When functioning as a USB device, the entire Crypto Connected LaunchPad can be powered directly from the USB micro A/B connector. Use JP1 to select the desired power source. USB 2.0 functionality is provided and supported directly out of the box with the target USB micro A/B connector. High-speed USB 3.0 functionality can be enabled by adding an external USB PHY. The USB external PHY control and data signals are provided on the breadboard expansion header X11. 2.1.5 Motion Control The Crypto Connected LaunchPad includes the TM4C Series Motion Control PWM technology, featuring a PWM module capable of generating eight PWM outputs.

This interface is fully compliant with the BoosterPack standard and adds features not covered by the BoosterPack standard that enable operation with additional BoosterPacks. An additional analog signal is provided on the outer left header (X6-9). This signal can be used to monitor the touch panel on the popular Kentec EB-LM4F120-L35 BoosterPack. Using the jumpers JP4 and JP5, Controller Area Network (CAN) digital receive and transmit signals can be optionally routed to the BoosterPack 2 interface. The location of these signals is consistent with the CAN interface on the TM4C Series TM4C123G LaunchPad and the Stellaris LM4F120 LaunchPad. In the default configuration, UART0 is used for the ICDI virtual UART and CAN is not present on the BoosterPack headers. In this configuration, the ROM serial bootloader can be used over the ICDI virtual UART. When the jumpers are configured for CAN on the BoosterPack, then UART2 must be used for the ICDI virtual UART. To comply with both the original and the new BoosterPack standard, I2C is provided on both sides of the BoosterPack connection. Use of I2C on the bottom left of the BoosterPack connection is highly encouraged where possible, to be in compliance with the new BoosterPack standard. To provide I2C capability on the right side of the connector, per the original standard, two zero-ohm resistors (R19 and R20) are used to combine the SPI and I2C signals. These signals are not shared with any other pins on the LaunchPad and therefore removal of these zero-ohm resistors should not be required. Software should be certain that unused GPIO signals are configured as inputs. Table 2-2 provides a complete listing of the BoosterPack pins and the GPIO alternate functions available at each pin. The TM4C129ENCPDT GPIO register GPIOPCTL values are shown for each configuration. The headers in this table are labeled from left to right in ten pin columns. ‘A’ and ‘D’ make up the outer BoosterPack standard pins, ‘B’ and ‘C’ make up the inner BoosterPack XL standard pins.

Properly combined with a pair of right angle headers, the entire Crypto Connected LaunchPad can be plugged directly into a standard 300 mil (0.3 inch) wide solder-less breadboard. The right angle headers and breadboard are not provided with this kit. Suggested part numbers are Samtec TSW-149-09-L-S-RE and TSW-149-08-L-S-RA right angle pin headers and Twin industries TW-E40-1020 solder-less breadboard. Samtec TSW-149-09-F-S-RE and TSW-149-09-F-S-RA may be substituted. A detailed explanation of how to install the headers is available on the TI LaunchPad Wiki or at http://users.ece.utexas.edu/~valvano/EE345L/Labs/Fall2011/LM3S1968soldering.pdf. Nearly all microcontroller signals are made available at the breadboard adapter holes (X11). These signals are grouped by function, where possible. For example, all EPI signals are grouped on one side of the connector. Many of the analog signals are grouped near VREF, and UART, SSI and I2C signals are grouped by peripheral to make expansion and customization simpler. Table 2-3 and Table 2-4 show the GPIO pin and signal muxing for the X11 breadboard adapter pads. Table 2-3.

The top position is for BoosterPack power; this position also disconnects both USB voltages from the board’s primary 5-V input. In the top position, the TPS2052B does not limit current so additional care should be exercised. The middle position draws power from the USB connector on the left side of the board near the Ethernet jack. The bottom position is the default, in which power is drawn from the ICDI (Debug) USB connection. JP2 separates the MCU 3.3-V power domain from the rest of the 3.3-V power on the board allowing an ammeter to be used to obtain more accurate measurements of microcontroller power consumption. JP3 isolates the output of the TPS73733 LDO from the board’s 3.3-V power domain. JP4 and JP5 are used to configure CAN signals to the BoosterPack 2 interface. In the default horizontal configuration, CAN is not present on the BoosterPack. UART2 goes to the BoosterPack and UART 0 goes to the ICDI virtual serial port to provide ROM serial bootloader capability. In the vertical CAN-enabled configuration, UART2 goes to the ICDI virtual serial port and CAN signals are available on the BoosterPack. The ROM serial bootloader is not available to the ICDI virtual serial port while the jumpers are in the CAN position. Figure 2-2 shows the default configuration and relative location of the jumpers on the board. Figure 2-2. Default Jumper Locations 2.2 Power Management 2.2.1 Power Supplies The Crypto Connected LaunchPad can be powered from three different input options: • On-board ICDI USB cable (Debug, Default) • Target USB cable • BoosterPack or Breadboard adapter connection The JP1 power-select jumper is used to select one of the power sources. In addition, the JP3 power jumper can be used to isolate the 3.3-V output of the TPS73733 from the board’s 3.3-V rail. A TPS2052B load switch is used to regulate and control power to the Target USB connector when the microcontroller is acting in USB host mode. This load switch also limits current to the BoosterPack and Breadboard adapter headers when the JP1 jumper is in the ICDI position. 20 Hardware Description SPMU372A – September 2015 – Revised October 2016 Submit Documentation Feedback Copyright © 2015–2016, Texas Instruments Incorporated Power Management www.ti.com 2.2.2 Low Power Modes The Crypto Connected LaunchPad demonstrates several low power microcontroller modes. In run mode, the microcontroller can be clocked from several sources such as the internal precision oscillator or an external crystal oscillator. Either of these sources can then optionally drive an internal PLL to increase the effective frequency of the system up to 120 MHz. In this way, the run mode clock speed can be used to manage run mode current consumption. The microcontroller also provides sleep and deep sleep modes and internal voltage adjustments to the flash and SRAM to further refine power consumption when the processor is not in use but peripherals must remain active. Each peripheral can be individually clock gated in these modes so that current consumption by unused peripherals is minimized. A wide variety of conditions from internal and external sources can trigger a return to run mode. The lowest power setting of the microcontroller is hibernation, which requires a small amount of supporting external circuitry available on the Crypto Connected LaunchPad. The Crypto Connected LaunchPad can achieve microcontroller current consumption modes under 2 micro-Amps using hibernate VDD3ON mode. Hibernation with VDD3ON mode is not supported on this board. The Crypto Connected LaunchPad can be woken from hibernate by several triggers including the dedicated wake button, the reset button, an internal RTC timer and a subset of the device GPIO pins. The hibernation module provides a small area of internal SRAM that can preserve data through a hibernate cycle. 2.2.3 Clocking The Crypto Connected LaunchPad uses a 25 MHz crystal (Y1) to drive the main TM4C129ENCPDT internal clock circuit. Most software examples use the internal PLL to multiply this clock to higher frequencies up to 120 MHz for core and peripheral timing. The 25-MHz crystal is required when using the integrated Ethernet MAC and PHY. The Hibernation module is clocked from an external 32.768-KHz crystal (Y3). 2.2.4 Reset The RESET signal to the TM4C129ENCPDT microcontroller connects to the RESET switch, BoosterPack connectors, Breadboard adapter and to the ICDI circuit for a debugger-controller reset. External reset is asserted (active low) under the following conditions: • Power-on reset (filtered by and R-C network) • RESET switch is held down. • By the ICDI circuit when instructed by the debugger (this capability is optional, and may not be supported by all debuggers) • By an external circuit attached to the BoosterPack or Breadboard connectors. 2.3 Debug Interface 2.3.1 In-Circuit Debug Interface (ICDI) The Crypto Connected LaunchPad comes with an on-board ICDI. The ICDI allows for the programming and debugging of the TM4C129ENCPDT using LM Flash Programmer and/or any of the supported tool chains. Note that ICDI only supports JTAG debugging at this time. It is possible to use other JTAG emulators instead of the on board ICDI, by connecting to U6. When the ICDI detects an external debug adapter connection on the JTAG connector U6 and disables the ICDI outputs to allow the external debug adapter to drive the debug circuit. For more information, see Section 2.3.2. Debug out of the ICDI is possible by removing resistors R6, R7, R8, R10, R11, R15, R16 and R40 from the Crypto Connected LaunchPad and use the ICDI to drive JTAG signals out on U6 for the purpose of programming or debugging other boards. To restore the connection to the on-board TM4C129ENCPDT microcontroller, install jumpers from the odd to even pins of X1 or re-install the resistors. Removal of R40 disables the detection of an attached external debugger. R40 must be installed to use an external debug adapter to program or debug the Crypto Connected LaunchPad.

This connector follows the ARM standard 10-pin JTAG pinout. This interface can use either JTAG or SWD if supported by the external debug adapter. 2.3.3 Virtual COM Port When plugged into a USB host, the ICDI enumerates as both a debugger and a virtual COM port. JP4 and JP5 control the selection of which UART from the TM4C129ENCPDT is connected to the virtual COM port. In the default configuration, UART0 maps to the virtual COM port of the ICDI. In the CAN jumper configuration, UART2 maps to the virtual COM port of the ICDI. 22 Hardware Description SPMU372A – September 2015 – Revised October 2016 Submit Documentation Feedback Copyright © 2015–2016, Texas Instruments Incorporated Chapter 3 SPMU372A – September 2015 – Revised October 2016 Software Development This chapter provides general information on software development as well as instructions for flash memory programming. 3.1 Secure IoT Demo 3.1.1 Software Description The out-of-box “Secure IoT” application demonstrates the use of Transport Layer Security/Secure Sockets Layer (TLS/SSL) protocol to connect an IoT product to a cloud server securely.
