CC3135)

1 Introduction

1.1 CC3135 BoosterPack™

The SimpleLink™ Wi-Fi®CC3135 dual band (2.4GHz and 5GHz) wireless network processor provides

users the flexibility to add Wi-Fi®to any microcontroller (MCU). This user's guide explains the various

configurations of the CC3135 BoosterPack™ Plug-in Module. This Internet-on-a chip™ integrated circuit

solution contains everything needed to easily create Internet of Things (IoT) solutions, including enhanced

security features, quick connection establishment, cloud support, and more. The CC3135 BoosterPack™

module can be used in the following ways:

• The module can be connected to a TI MCU LaunchPad™ Development Kit (software examples

provided for MSP-EXP432E401Y).

• The module can be plugged into a CC31xxEMUBOOST board, and connected to a PC for MCU

emulation.

• The module can be connected to an adapter board DISCOVERY-ADAPT, which enables customers

use the BOOSTXL-CC3135 with additional platforms beyond TI LaunchPad™ kits.

The CC3135 BoosterPack™ kit can be purchased in three configurations:

1. BOOSTXL-CC3135 plus CC31XXEMUBOOST board plus MSP-EXP432P401R LaunchPad™

Can run all software in the software design kit (SDK), and develop on the MSP430F5529 MCU

2. BOOSTXL-CC3135 plus CC31XXEMUBOOST board

Used for any CC3135 device development

3. BOOSTXL-CC3135

If extra CC3135 BoosterPack™ modules are needed.

NOTE: The CC31XXEMUBOOST board is an advanced emulation board that is required for flashing

the BOOSTXL-CC3135, using the radio tool (radio performance testing or putting into

certification modes), and doing networking processing logs for advanced debugging.

The pictures used in this user's guide refer to the Revision A board, but the contents also

apply to any higher revisions unless otherwise stated. For changes across the various

revisions of the board, see Section 5.3.

The maximum RF power transmitted in each WLAN 2.4-GHz band is 18.3 dBm. The

maximum RF power transmitted in each WLAN 5-GHz band is 17 dBm.

The antennas used for this transmitter must be installed to provide a separation distance of

at least 20 cm from all people, and must not be colocated or operating in conjunction with

any other antenna or transmitter.

2.3 Connector and Jumper Descriptions

2.3.1 Push-buttons and LEDs

Table 1 lists the push-button descriptions.

Table 1. Push-buttons

Reference Usage Comments

SW3 Factory default This button is used to restore the serial flash to the factory default image. Hold the

button and then toggle the RESET push-button.

SW2 RESET This button can be used to reset the device. Holding the button down sets the device in

the SHUTDOWN state.

SW1 nHIB This button boots the device to the bootloader mode for flashing the firmware over a

universal asynchronous receiver/transmitter (UART).

Table 2 lists the LED descriptions.

Table 2. LEDs

Reference Color Usage Comments

D3 Red PWR indication On, when the 3.3-V power is provided to the board.

D6 Yellow nRESET This LED indicates the state of the nRESET pin. If this LED is glowing, the

device is functional.

D5 Green nHIB This LED indicates the state of the nHIB pin. When the LED is off the device

is in HIBERNATE state.

D7 Red Factory default This LED indicates whether the factory default switch is pressed on. The

RESET button must be pressed for this LED to function.

J8 (1 to 2) power from the MCU LaunchPad™

J8 (2 to 3) power from the onboard USB using a 3.3-V LDO

J8 Current measurement

For hibernate and LPDS currents, connect an ammeter across J26

(range < 500 µA).

For active current, mount a 0.1-Ωresistor on R42, and measure the voltage

across the 0.1-Ωresistor using a voltmeter (range < 50 mV peak-peak).

P1…P4 BoosterPack™ header 2 × 10 pins each connected to the LaunchPad™

J10 RF test (2.4 Ghz only) U.FL connector for conducted testing in the lab. Using this requires an ECO be

2.3.3 Assignment of the Two 20-Pin Connectors

Figure 3 shows the signal assignment on the two 20-pin connectors. The convention of J1...J4 is replaced with P1…P4 to avoid confusion with the

actual board reference.

Figure 3. Pin Connector Assignment

NOTE: All signals are 3.3-V CMOS logic levels, and are referred with respect to the CC3135 device. For example, UART1_TX is an output from

the CC3135. For the SPI lines, the CC3135 device always acts like a slave.

2.4 Power

The board is designed to accept power from a connected LaunchPad™ kit, or through the

CC31xxEMUBOOST board. Some LaunchPad kits cannot source the peak current requirements of Wi-Fi,

which may be as high as 450 mA. In such cases, the USB connector on the BOOSTXL-CC3135 can be

used to aid the peak current. The use of Schottky diodes ensure that load sharing occurs between the

USB connectors on the LaunchPad kit and the BoosterPack™ module without any board modifications.

Also, the 3.3-V power can be sourced from the LaunchPad kit or from the 3.3-V LDO on the board. This

sourcing is done by using jumper J8. If the LaunchPad kit is unable to source the 3.3 V up to 450 mA,

then J8 must be configured to work from the onboard LDO.

2.4.1 Power From the LaunchPad™ Kit or CC3135EMUBOOST

The most common scenario is powering the BOOSTXL-CC3135 from the connected LaunchPad™ kit. In

this case, the LaunchPad kit provides 3.3 V to the BoosterPack™ module for its operation (see Figure 4).

In addition to the 3.3 V, some LaunchPad kits provide 5 V from the USB (see Figure 5), which is used to

drive a 3.3-V LDO on the BoosterPack module. If the LaunchPad kit is unable to provide the 5 V (for

example, the LaunchPad kit with only 20 pins), then the USB connector on the BOOSTXL-CC3135 must

be used to provide the LDO input, as shown in Figure 5.
