designing sample.

Remarks: In the system, the module layout should be far away from high-speed circuit, switch power, power
transformer, large power inductor, or single chip microcomputer’s clock circuit.
4.2 Power and Reset
4.2.1 Power Design
The module could work under two modes: 1. powered by power adaptor; 2. powered by battery.
The EUT was suppliped by a special supply unit,which is connected to a pc via a usb port ,this
supply unit could be recognised as a power supply.The EUT worked at 3.4~4.2V DC.
The power could be directly supplied by external power, which is directly added to V_MAIN and satisfy the
voltage in the table 4-1. The external power could be power adaptor, battery, USB power convertor, etc. It’s
recommended that the safe power current is 2A to satisfy the GSM and GPRS mode.
Charge input: For some application with Li-battery, the Li-battery charge manage was embedded in Module,
please note the input charge voltage should be DC :5V±0.5V
Table 4-1 Voltage Features
Classification Min. Typical Max.
Input voltage 3.4V 3.8 V 4.2 V
The supply power of Module should be DC from 3.3V to 4.2V,please refer to the following schematic to
design the power of Module:
SEW290 WCDMA Module
14
Power-on
The module could be turned on in the following method.
After the module is powered off, and then provide a 3000-4000ms low level pulse to ON/OFF PIN.
Power-off
To turn off the module, provide a 3000-4000ms low level pulse to ON/OFF PIN as the module is powered on.
V_MSME_1V8
SEW290 contains V_MSME_1V8 pin with limiting regulator function to supply power to the module external
circuit.The voltage of this pin with the BSP and Memory comes from the same voltage regulator.Only when the
module is powered on,this pin has voltage output.the normal output voltage is 1.8V.User should active the
current of this pin as little as possible(usually less than 10mA).
Generally,it's suggested that this pin used for Chip pins level matching demand pullup.
In order to ensure that the module data can be kept safely and for module data security, do not Cut off the power
supply when module is running.User should use the ON/OFF pin or AT commands for ON/FF operation.
4.2.2 Reset
You could turn off the module firstly and then turn it on to reset the module when the module software stops
responding.Provide a 50~200ms low level pulse to the /PON_RESET pin as the module can reset.
Please refer to figure 4-1 for the module reset external circuit.
figure 4-1 Module reset external reference design circuit
SEW290 WCDMA Module
15
Remarks:this pin is sensitive to interference.The external circuit line length of this pin should no longer than
2cm,otherwise the interference may active the reset pin.
4.3 UART
The module provides an integrated full duplex full flow control UART interface, whose maximal data rate is
230.4kbps, typical value is 11.5kbps. External interface is 1.8V CMOS level signal, input is compatible.
Remarks:to support the UART function the module software needs update.
When using SEW290 module’s URAT interface to communicate with PC or MCU,please pay attention to TX
and RX direction, especially, note that SEW290 UART interface only supports 1.8V. Therefore, the triode is
usually used to realize level conversion for non 1.8V external UART. See figure 4-2, the resistance is just for
reference. Please recalculate when designing it.
Figure 4-2 UART interface external reference design circuit
4.4 4.4 USIM Card
SEW290 module supports the ClassB-3V and ClassC-1.8V USIM card, which includes 4 pins at the end.
USIM card PCB layout should be close to the module as much as possible to avoid the interference of
reading/writing USIM card from other sources.It’s strongly recommended to add ESD protection component
when designing UIM circuit. See ESD protection component D2 in figure 4-3.
NOTE: Considering the difference on the output current from DATA pin of different cards, a 10K resistor
should be used to pull up DATA pin to V_CARD(VREG_USIM).

4.5 Audio
The module provides two audio inputs and two audio outputs through stamp-hole PIN. The module also
provides 2 microphone interfaces and only one pair I/O works at the same time. Two audio outputs include 1
receiver differential output and 1 headset single-end output.
Microphone
It provides two microphone interfaces MIC1 and MIC_P, among which MIC2_P is differential interface.
These two microphone inputs are internally coupled in AC domain and added a 1.8V offset voltage to directly
connect the microphone.
Earpiece
It provides two earpieces: EAR1 & EAR2_P, and EAR1 is differential interface with 32Ωresistance;while
EAR2_P is single-ended interface with 32Ωresistance.
Design of audio interface on the receiver
Select the microphone with the sensitivity lower than -52dB since the output power for EAR1 is 50mW and the
max. gain in MIC1 can reach up to 52dB. The level of MIC_1P is about 1.8V.
Note: if other kind of audio input method is adopted, the input signal should be within 2V. If the signal voltage is
lower than 2V, then the pre-amplifier should be added. If the signal voltage is higher than 2V, then network
attenuation should be added.
Design of audio interface on the earpiece
Select the microphone with the sensitivity lower than -52dB since the output power for EAR2_P is 8.8mW and
the max. gain in MIC2_P can reach up to52dB. The level of MIC_P is about 1.8V. The design is almost the
same.
If EAR2_P is used for hands-free speaker output, an audio power amplifier should be added.

SEW290 WCDMA Module

4.5 PCM
SEW290 Module's PCM interface provides PCM_CLK, PCM_SYNC, PCM_DIN, PCM_DOUT four
pins,supports 2.048MHz clock rate and 8K frame rate. PCM clock in the module will stop when the module go
into a sleep mode. PCM interface provides signal transmission application such as voice for an external Bluetooth
device.
The module must work on the Master state cause the PCM_SYNC signal and PCM_CLK signal must output when
PCM master.The PCM device connected to module PCM can only work on Slave state.
Figure 4-5 Module PCM working mode diagram
SEW290 WCDMA Module
19
Figure 4-6 Module PCM working time sequence diagram
4.6 USB 2.0
The module provides a USB2.0 high speed (480Mbps)interface, which is composed of VBUS, D+ and D-. The
module’s external circuit could connect directly with USB signal connector, but during the design process, try to
add ESD protection component to avoid damage. D12 in Figure 4-7 shows USB2.0 ESD protection component
with the junction capacitance is smaller than 3pF. VBUS could connect directly with VBUS at external host end.
The USB recommended voltage is: 3.0-5.6V, typical 5V.
