Wi-Fi 802.11 b/g/n Bluetooth® v3 BLE

Wi-Fi 802.11 b/g/n Bluetooth v4.0 BLE - for microprocessors

The Type TN module is based on Texas Instruments WL1271L chipset supporting the standards for IEEE802.11 b/g/n WiFi, Bluetooth v4.0, including Bluetooth low energy (BLE) connectivity. The type TN module is intended for broad market use by incorporating additional features on-module to simplify customer implementation. The modules dimensions are 17.0 x 10.0 x 2.2 mm. WLAN host interface is SDIO, Bluetooth host interface is UART.

Platforms

The Type TN module is pre-integrated on select Texas Instruments OMAP, SITARA, DaVinci, and Integra processor development platforms.  Pre-integration facilitates fast design cycles.  We recommend customers begin with the TI AM335x EVM reference platform.  Bundled within the AM335x EVM is the Type TN module mounted on the Com6M daughter card.  The Com6M daughter card interfaces directly into the TI AM335x EVM.  EVM information can be found on the AM335x EVM wiki pages

Frequently Asked Questions for Type TN

Q: Can you recommend a reference schematic? 

A: Please use the Com6M schematic as reference.

 

Q: Does the module 2.4GHz interface include both a PCB pad and a U.FL connector?

A: Yes.  The customer can choose either interface.  Simply plug-in a mating U.FL cable assembly to interface the module to its antenna.  Or, use the PCB pad, pin 40, as a 2.4GHz transmission line launch point to route to an SMT antenna. 

 

Q: What is the module U.FL part number?

A: The coaxial connector is U.FL-R-SMT-1 from Hirose. 

 

Q: How much direct current is supplied to the 1.8v input?

A: Typically less than 2mA.  Suggest a 10mA capable regulator.

 

Q: What is the impact of choosing 2.7v, 3.6v, or 4.8v in supplying the VBAT input?  

A: There is little impact or performance trade-off in selecting the VBAT rail.  The PA is largely insensitive in terms of current, power, and linearity over the specified range.  

 

Q: Could you explain the logic and function for pin 6 WLAN_EN and pin 10 BT_EN?

A: Both are enable pins, one for the WLAN core, the other for the Bluetooth core.  Logic 1 is enabled, logic 0 is disabled.  Disable is an off state with minimal current consumption.

 

Q: Please explain the BT UART signals, pins 27? 

A: UART_RTS is a module output signal for flow control from the module's HCL receiver.  

 

Q: Please explain the BT UART signal pin 28?

A: UART_CTS is a module input signal, it is flow control to the module's HCL transmitter.

 

Q: Explain BT UART signal pin 29?

A: UART_TX is a module output signal.

 

Q: Explain BT UART signal pin 30?

A: UART_RX is a module input signal.

 

Q: How should I connect BT function pins BT_FUNC1, BT_FUNC5, BT_FUNC6?

A: These signals are 'no connects'.  Leave them as open circuit.
