NOTE：Make sure that the VBAT can never exceed 4.5VDC. Voltage higher than 4.5VDC may damage the

WM620 module.

2.1.1 Power Supply Requirements

VBAT is the main power input ranged from 3.3V to 4.2V DC, 3.8V DC is recommended. The average current

is less than 500mA@3.8VDC. But in the module’s transmitting mode, the largest current can burst up to 1.8A

providing the RF power amplifier. The burst current may cause deep voltage drop, and trigger the module into

a power reset. Thus a high value and low ESR capacitor must be installed on the VBAT, to avoid or reduce the

voltage drop caused by the RF power amplifier.

Figure 2-1a, current and voltage curve of VBAT

WM620 Hardware User Guide V1.1

Figure 2-1b, Schematic circuit for current test

The current test results related to the ESR of the capacitors and the internal resistance of the power source. A

470uF tantalum electrolytic capacitor or a 1000uF low ESR aluminum electrolytic capacitor is recommended

for C1. Lithium battery is a very low resistance power source. If the VBAT is supplied by a lithium battery,

220uF or 100uF tantalum capacitor can fit the current require for VBAT. These 10uF, 0.1uF, 100pF and 33pF

MLCC capacitors should be placed close to the VBAT pin.

ESD, Lightning Surge or other interferences can rarely cause the WM620 to stop running. Reset the power

supply can recover the module. So the power control is very important in the unattended applications. VCC_EN

in figure 2-2 is the switch to control the power.

The recommended design of power supply is shown in figure 2-2a. In this circuit, with the EN pin of

LDO/DC-DC, power supply can be controlled by the external MCU or other master device. If the LDO or

DC-DC has no EN pin, a low on-resistance P-MOSFET can work as a power switch. The P-MOSFET power

switch shown in Figure 2-2b can replace the function of EN pin.

Figure 2-2a

WM620 Hardware User Guide V1.1

Figure 2-2b

2.1.2 VRTC Interface

VRTC Pin is used as an analog input from the 3 V coin cell for SMPL(Sudden Momentary Power Loss),

RTC(Real-time Clock), and crystal oscillator to keep alive power when the module is powered off. A capacitor

(rather than a coin cell) can be used if only SMPL is supported (not RTC or XTAL).

Figure 2-3

VRTC pin is also used as an analog output to charge a coin cell or a capacitor. When supply current is sourced

from the main power supply through VBAT pin. The on-chip coin cell charger is implemented using a voltage

regulator and series resistor.

If the monitored VBAT drops out-of-range (< 2.55V nominal), the SMPL feature initiates a power-on sequence

without software intervention, and then VBAT returns in-range within a programmable interval of between 0.5

and 2.0 seconds. SMPL achieves immediately and automatically recovery from momentary power loss. A valid

voltage on VRTC is required to run the SMPL timer.

If a capacitor is used instead of a coin cell, it must be connected between VRTC PIN and the ground, Figure

2-3 shows the reference RTC circuit. The capacitor must be charged to operate properly as the SMPL power

source. The capacitor value depends on the SMPL timer setting. Table 2-2 shows the capacitor value of VS

SMPL time.

2.1.3 Power Supply Output

The VDD_1.8V and VDD_2.6V pins are two linear regulator outputs. These two pins can supply the same

output current of 20mA (typical value). These two power supplies can be used for logic level conversion

circuits between WM620 and external devices, and not recommended as a general-purpose power source for

other application circuits.

VDD_2.6V circuit keeps operating while the WM620 module in sleep mode.

2.1.4 Power on Sequences

Figure 2-4 shows the power on sequencing of WM620.

Figure 2-4

2.2 Power ON/OFF and Reset

2.2.1 ON_OFF

ON_OFF is an input pin with an internal pull-up resistance. Launch a valid low level pulse to ON_OFF can

control the WM620’s system into Start-up or shut-down mode. The pulse width requirement and power on

sequence are shown in figure 2-4.

When the WM620 power on, the VDD_2.6V pin would rise up and keep on 2.6V DC, and then the module's

serial port will automatically issue a keyword string, means that the module system is running and AT

commands is ready.

WM620 Hardware User Guide V1.1

While the WM620 is in running mode, low level pulse can put the module system into shutdown procedure.

And then the module would power off within after 5S.

Instead of ON_OFF pin, An AT command can also shutdown the module. For more specific, please refer to the

WM620’s AT command manual.

Keeps the ON_OFF low or connecting to GND, WM620 can automatically power up when VBAT is supplied.

High level pulse control circuit of ON_OFF is shown in Figure 2-5：

Figure 2-5

2.2.2 RESET_N

RESET_N is an active low signal with an internal pull-up resistance and acts as hardware reset input.

Low level pulse longer than 20mS can reset the WM620. After reset the module, power on operations, such as

launch a low level pulse to the ON_OFF pin, must be done again. The recommended reset pulse is 50ms, but

can not exceed 2S. Otherwise, the WM620 module will power off.

If keeps the ON_OFF low or connecting to GND, the WM620 can automatically power up after reset the

module.

WM620 module supports 3V & 1.8V SIM cards. The SIM_DATA pin needs an externally 10K pull-up

resistor connected to V_SIM.The SIM_CLK is the clock signal, normally 3.25MHz. Bifurcation is not

recommended at the PCB trace of SIM_CLK.

Include SIM_DATA and SIM_CLK, the traces should be as short as possible and surrounded by the ground

copper to reduce the RF interference. The total distributed capacitance, include the junction capacitance of the

ESD diode or other device, can’t be higher than 120pF.

The SIM card application circuit is shown in Figure 2-9. In automotive electronics or other applications with

strong ESD, ESD diodes or ESD varistors are strongly recommended, such as T1 to T4. T1 to T4 should be

place closed to SIM card. In some clear applications, SIM card is installed in closed box without human touch,

22~33pF MLCC capacitors can replace the ESD diodes for cost down.

WM620 Hardware User Guide V1.1

Note：SIM card is very sensitive to RF interference.

Serious RF interference to SIM card will cause the WM620 to miss the detection to SIM card and out of service.

So, it is very importance in the PCB design listed as the following message.

 The antenna should be installed a long distance away from the SIM card and SIM card traces.

 The SIM card traces should be routed as short as possible and shielded with GND copper.

 The ESD diodes or capacitors should be placed closed to SIM card.

The WM620 module is compliant with USB2.0 full speed device. The USB2.0 specification requires the hosts

such as PCs to support three USB speeds, namely low-speed (1.5Mbps), full-speed (12Mbps) and high-speed

(480Mbps).

The V_USB pin is an analog input. A 4.7µF decoupling MLCC capacitor to GND is strongly recommended,

and should be placed as closely as possible to V_USB Pin. It will increase the USB stability. ESD diodes

should be installed to these three signals. Shown in Figure 2-10.

Figure 2-10

Note: The layout design of this USB should comply with the USB 2.0.

 The traces of USB_D+ and USB_D- must be routed as a group of differential pair with 90Ω differential

impedance.

 The USB differential pair should be routed side-by-side and on the same layer.

 USB_D+ and D- is a pair of high speed signals, so the trace lengths should match as well as possible.

2.6.1 Basic Descriptions of UART

UART1 is for AT commands, data sending/receiving, firmware updating, etc.

As a DCE device, the module is connected to DTE as shown in Figure 2-11.

Supported baud rates are 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400bps, and the default is

115200.

Figure 2-11, Connection between DCE (module) and DTE

The UART of WM620 works at 2.6V CMOS logic level. The voltages for input high level should not exceed

3.0V.

2.6.2 Level Translators for UART

If the UART is interfacing with a MCU that has 3.3V logic levels, resistors should be connected in series with

the signals, shown in figure 2-12.

WM620 Hardware User Guide V1.1

Figure 2-12, Interfacing with 3.3V logic levels of MCU

If the UART is interfacing with a MCU that has 5V logic levels, general level translators are required, for both

inputs and outputs. As shown in Figure 2-13.

Figure 2-13, Interfacing with 5V logic levels of MCU

Reference components:

R2: 2K-10K. The higher rate the UART works at, the smaller value used

R3: 4.7K-10K. The higher rate the UART works at, the smaller value used

Q1: MMBT3904 or MMBT2222. High-speed transistors preferred.

Used for 5V logic -> 2.6V logic:

While this circuit used between MCU TXD and module RXD, the INPUT signal is connected to MCU TXD,

and OUTPUT connected to module RXD. VCC_IN powered from 5V and VCC_OUT powered from 2.6V

(module’s VDD_2.6V).

Used for 2.6V logic -> 5V logic:

It can be used between module TXD and MCU RXD as well, with INPUT connected to module TXD, and

OUTPUT connected to MCU RXD. VCC_IN powered from 2.6V (module’s VDD_2.6V) and VCC_OUT

powered from 5V. This applies to RING signal as well.

Note:

Avoid sparks and glitches on UART signals while the module is in a turning on procedure.

Avoid sending any data to UART during the beginning of 2 seconds after the module being turned on.

3 Mechanics, Mounting and Packaging

3.1 Dimension and PCB layout

Figure 3-1, WM620 PCB foot print

3.2 Assembly

The WM620 introduces 62 Pin LCC castellation technology, less pin counts and wide pitch, these features are very suitable

for low-cost and simple designs with 2 layer PCB. Benefit from it’s ultra-compact size and high reliability,

WM620 can be easily designed in. Moreover, WM620supports manual soldering, can adapt to mass production

and also low quantity perfectly, and has low technical requirement for manufacturing equipment.

WM620 Hardware User Guide V1.1

3.3 Packaging and solder

WM620 modules are packaged in sealed bags on delivery to guarantee a long shelf life. Package the modules

again in case of opening for any reasons.

If exposed in air for more than 48 hours at conditions not worse than 30°C/60% RH, a baking procedure should

be done before SMT. Or, if the indication card shows humidity greater than 20%, the baking procedure is also

required. The baking should last for at least 24 hours at 90℃.

In order to prevent the product of from being affected with damp, caused by using the SMT way to perform the

furnace welding, in the process of production and use of the costumer, we employ the way of damp-proof

packing, such as Aluminum Foil Bag, desiccating agent, Humidity Indicator Cards, Suck plastic trays, and

vacuolization. As a result the product is kept dry and its life span will be long.

For more storage and SMT information, please refer to 《Neoway modules’ recommendation for SMT and

reflow solder》.
