Fender FMA BT-FTSW-USB PCBA (PN 7710068000) Page 1 Manual and Spec, revision 1.0 November 8, 2016 Fender FMA BT-FTSW-USB PCBA (PN 7710068000) Manual and Spec, revision 1.0 Module Description The Fender FMA BT-FTSW-USB PCB Assembly is an auxiliary PCB used in the family of Fender Modular Architecture (FMA) products. The board has a USB port with a micro AB connector, a Fender Footswitch port with a ¼” phone jack and a wireless module. Circuit Description/Theory of Operation There are three main sections of the circuit: • Bluetooth module (FreeWings FW3817-30), antenna, & audio output circuit • USB port • Footswitch port The USB circuit consists of ESD protection components and a micro AB USB connector. The Footswitch circuit consists of ESD protection components and a ¼” phone jack connector. Both of these circuits are unrelated to the Bluetooth section, and are shared on the PCB for mechanical convenience. The FreeWings module is a complete Bluetooth implementation with analog audio output. An F-style antenna is connected to the RF output of the module through a test switch and matching network. The module is powered with a 3.3V DC supply and digital ground. The PCB is dual layer with digital ground plane sections stitched together on both sides where possible. The analog stereo audio output from the module is buffered by an op-amp stage before sending back to the host system. The analog audio buffer circuit has a separate power supply and ground system to isolate it from digital noise. All Bluetooth functionality is controlled by on-board firmware. But the module may be accessed for test through the SPI port to a computer interface module (available from FreeWings). A description of specific commands for Bluetooth is beyond the scope of this document and can be found in documentation from FreeWings or CSR for the CSR8630 chipset.

It should be that it was 0V voltage at any pin before reset.USB charger attach resetSoftware configured watchdog timer 7.2 Power on and power off FW3817-30 module is power on from two sources: VREG_EN pin pulled high for minimum 100ms when VBAT pin is in the status of stable power. VREG_EN pin pulled high from low when VBAT pin is in the status of stable power. The wrong timing sequence of VREN_EN and VBAT will lead to error of power on. FW3817-30 module is power off from two sources: VREG_EN pin pulled high for minimum 100ms when VBAT pin is in the status of stable power. VREG_EN pin pulled low from high when VBAT pin is in the status of stable power. The wrong timing sequence of VREN_EN and VBAT will lead to error of power off. 7.3 I/O The driver power voltage of all the PIO port is 1.8V inside of the module.

7.4 Battery Charger FW3817-30 module provides two kinds of battery charger controls. The internal charger circuit can provide up to 200mA of charger circuit. The module controls an external pass transistor which can provide 500mA of charger circuit. 7.5 USB USB_P and USB_N can be used to updating software or USB audio.Both of them request that VCHG pin must be supplied 5V power.The two data signals do not need any resistance or capacitance. 7.6 Absolute Maximum Ratings Rating Minimum Maximum Unit Storage Temperature -40 85 Supply VoltageVCHG -0.4 5.75 V LEDs -0.4 4.4 V VBAT SENSE -0.4 4.4 V VREG_EN -0.4 4.4 V VBAT -0.4 4.4 V 7.7 Recommended Operating Conditions Rating Minimum Typical Maximum Unit Operating Temperature -20 20 70 Supply Voltage VCHG 4.75 5.00 5.75 V LEDs 1.10 3.70 4.30 V PIO 1.50 1.80 1.90 V VBAT SENSE 0 3.70 4.25 V VREN_EN 2.80 3.70 4.25 V VBAT 2.80 3.70 4.25 V 7.8 Power consumption Status Current Typical Unit Power off VBAT 0.1 uA A2DP slave mode with no load and playing peak noise VBAT 12 mA A2DP slave mode with two16ohm speakers and playing peak noise VBAT 24 mA Pause in A2DP slave mode connection VBAT 0.5 mA
