    4 Hardware Commands 4.1 Turning ON the UE910 To turn on the UE910 the pad ON_OFF* must be tied low for at least 5 seconds and then released. The maximum current that can be drained from the ON_OFF* pad is 0,1 mA. A simple circuit to do it is: NOTE: Don't use any pull up resistor on the ON_OFF* line, it is internally pulled up.

  • Page 22 NOTE: In order to avoid a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the UE910 when the module is powered off or during an ON/OFF transition. For example: 1- Let's assume you need to drive the ON_OFF* pad with a totem pole output of a +3/5 V microcontroller (uP_OUT1): 2- Let's assume you need to drive the ON_OFF* pad directly with an ON/OFF button:...
  • Page 23 WARNING It is recommended to set the ON_OFF* line LOW to power on the module only after VBATT is higher than 3.22V. In case this condition it is not satisfied you could use the HW_SHUTDOWN* line to recover it and then restart the power on activity using the ON_OFF * line.

    5.3.3 Power Supply PCB layout Guidelines As seen on the electrical design guidelines the power supply shall have a low ESR capacitor on the output to cut the current peaks and a protection diode on the input to protect the supply from spikes and polarity inversion.
  • Page 39  The power supply input cables should be kept separate from noise sensitive lines such as microphone/earphone cables.  The insertion of EMI filter on VBATT pins is suggested in those designs where antenna is placed close to battery or supply lines. A ferrite bead like Murata BLM18EG101TN1 or Taiyo Yuden P/N FBMH1608HM101 can be used for this purpose.

  • Page 63: Mic Connection

    12.1.1 MIC connection The bias for the microphone has to be as clean as possible; the first connection (single ended) is preferable since the Vmic noise and ground noise are fed into the input as common mode and then rejected. This sounds strange; usually the connection to use in order to reject the common mode is the balanced one.
  • Page 64 If a "balanced way" is anyway desired, much more care has to be taken to Vmic noise and ground noise; also the 33pF-100Ohm-33pF RF-filter has to be doubled (one each wire). TIP: Since the J-FET transistor inside the microphone acts as RF-detector-amplifier, ask vendor for a microphone with anti-EMI capacitor (usually a 33pF or a 10pF capacitor placed across the output terminals inside the case).

  • Page 65: Line In Connection

    12.1.2 LINE IN Connection If the audio source is not a mike but a different device, the following connections can be done. Place 100nF capacitor in series with both inputs, so the DC current is blocked. Place the 33pF-100Ohm-33pF RF-filter, in order to prevent some EMI field to get into the high impedance high gain MIC inputs.

  • Page 66: Ear Connection

    12.1.3 EAR Connection The audio output of the UE910 is balanced, this is helpful to double the level and to reject common mode (click and pop are common mode and therefore rejected). These outputs can drive directly a small loudspeaker with electrical impedance not lower than 16 Ohm.
