Board Layout
The Smart Tag evaluation board assembly top view is shown in Figure 2. The resistors for memory selection are
highlighted in red.
Figure 2: Board Assembly (Top View)
By default, the board is set to use the internal LPO for sleep, but it can be set to use external LPO by installing
R102 and R103, highlighted in Figure 2, above. Resistor values are listed in Ta b l e 1 , below.
By default, the board is set to use EEPROM but can be set for serial flash by adjusting the resistors highlighted
in Figure 2 to the desired setting (shown in Ta b le 2).

Broadcom®
August 27, 2015 • 920737TAG04-HWUM101-RDS Page 11
BCM920737TAG-04 WICED Smart Tag Hardware User Manual
Power-Up Options
VDDIO can be sourced from three options:
• Coin cell unregulated
• Coin cell regulated
• USB regulated
These options are set using SW2 and SW3 (see Figure 2 on page 9), as listed in Ta b l e 3 . The default regulator
output is 1.8V.
To adjust the regulator output, feedback components can be adjusted as shown in Ta b l e 4 .
UART Boot-Up
The following procedure describes how to power up the tag board with the UART interface enabled.
1. SW4 and SW5 should be placed in the desired power configuration, as shown in Table 3.
2. SW6 should be in HCI mode by placing DIP switches 2 and 4 in the ON position (these positions are
considered standard until you wish to enter app mode).
3. Plug in the USB cable to connector J7. The Smart Tag will display in the Windows Device Manager as two
COM ports named Silicon Labs Dual CP210x USB to UART Bridge: Enhanced COM Port (COM##),
where ## is the number of the assigned com port.
The evaluation board can now accept HCI commands or download firmware through the UART interface.

2.0V RFB1 = 360 kΩ, RFB2 = 240 kΩ, C22 = 150 pF
Note: If the device driver does not load correctly, the FTS2232H driver must be downloaded from the
FTDI website (see http://www.ftdichip.com/Drivers/VCP.htm).

Boot from ROM
The following procedure describes how to boot the Smart Tag board from ROM. This is available if the NVRAM
is corrupted and the device is unable to boot correctly.
1. SW4 should be in the VUSB position and SW5 should be in the VREG position.
2. SW6 should be in HCI mode by placing DIP switches 2 and 4 in the ON position.
3. Press and hold the BOOT ROM button (SW1) and power up the device by plugging in the USB cable to
connector J7. The BOOT ROM button (SW1) can be released after the device is identified in the Windows
Device Manager.
or
Press and hold the BOOT ROM button (SW1), press and release RESET (SW3), release the BOOT ROM
button (SW1).
The evaluation board can now accept HCI commands or download firmware through the UART interface.
Application Firmware Software Boot-Up
The procedure below describes how to power up the Smart Tag board to run application firmware.
1. SW4 should be in the VUSB position and SW5 should be in the VREG position.
2. Set SW8 DIP switches 1, 3, and 5 to the ON position (EEPROM). All other SW8 DIPs should be in the OFF
position.
3. Set SW6 DIP switches 2 and 4 to the ON position and switches 1 and 3 OFF position.
The Smart Tag is now ready to be run the application firmware stored in EEPROM or serial flash, depending on
the jumper configuration.
