Note 1: “NC” means: leave unconnected.
“GND” means internally connected to the module ground plane. Every GND pin should be connected to the main PCB.ground plane.
Note 2: All digital inputs have Schmitt trigger inputs. After reset all I/Os are set to input and all pull-up or pull-down resistors are enabled unless oth-
erwise specified.
PU = Pull-up resistor enabled, PD = Pull-down resistor enabled, I = input,
O = output, Hi-Z = high impedance, 1 = logic HIGH level, 0 = logic LOW level
Refer also to Px_DIR_REGs for INPUT/OUTPUT and Pull-up/Pull-down configurations
Note 3: Back drive protected pins allow always interfacing with devices up to a supply voltage of 3.45 V.
If PAD_CTRL_REG[xxx_OD] bit is set then
1) the internal Pull-up resistors are always disabled to prevent currents from 1.8 V < Vin < 3.45 V to VDD.
2) If port is set to output, the output is always configured as open drain to allow the output level to reach Vin >1.8 V. The external pull-up
resistor value determines the rise time of the signal.
Note 4: For base station applications with high line input voltages, an input protection on all ADC inputs can be enabled with
AD_CTRL_REG[ADCx_PR_DIS] =’0’. To limit the input current as specified in chapter “specifications”, an external resistor must placed in
series with the ADC inputs. With the input protection enabled, the ADC is linear from 0 to 0.9 V. With ADCx_PR_DIS=’1’ the ADC0 and
ADC1 are linear from 0 V to 1.8 V.
Note 5: In digital mode extra static VDDPA current will flow (See Supply currents (indicative value) (table 9, page 14)). So the digital mode is not
recommended in portable applications.The reason for this output overvoltage protection is that a speaker is an inductor (which can store
energy). In case the battery is removed from the handset while handsfree speaker is active, the battery voltage could become too high
when the inductor releases its energy to the battery (which is not present anymore as a buffer). To prevent this electrical overstress situa-
tion, the overvoltage protection is added.
Note 6: This pin description describes all function that is supported by hardware. Supported pin function depends on installed software.
Note 7: All ULP pins use snap-back devices as ESD protection, which (when triggered) have a holding voltage below the typical battery voltage.
This means that the snap-back device of a ULP pin may remain conductive, when triggered while the pin is directly connected to the battery
voltage. If any of the ULP pins are directly or indirectly electrically accessible on the outside of the application, system level ESD precau-
tions must be taken to ensure that the snap-back device is not triggered while in active mode, to prevent the chip from being damaged.
81-88 TP2 to TP9 NC Must be left unconnected. See section 4.1 and Figure 15.

2.4 BLOCK DIAGRAM
2.5 POWER SUPPLY
Figure 3 shows the internal power supply circuit of the
SC14SPNODE SF.
2.6 ANTENNA OPERATION
Figure 4 shows the internal antenna circuit of the
SC14SPNODE SF. Pin RF0 is used for two external
antennas and can also be used for RF test purposes,
so it is recommended to add a 10 pF capacitor as
reserve pattern even when the two external antennas
are not used.
Re-certification of the SC14SPNODE SF is required if
at least one external antenna is added. On request,
Dialog Semiconductor can provide a pre-certified PCB
layout for an external antenna circuit.
RF1 is also recommended to use and can be con-
nected to the RF cable to be able to do the JPN DECT
type approval test.
2.6.1 Internal antenna only
The FAD function is not enabled if only the internal
antenna is used. In this case RFP0, RFP0n, P0 and
P0n must be left unconnected.

2.6.2 Internal and external antenna with FAD
Figure 5 shows one external antenna that is connected
to RF1 of the SC14SPNODE SF. This configuration
supports the FAD function. In this case pins RFP0,
RFP0n, P0 and P0n must be left unconnected. The
software patch code is not needed if the
SC14SPNODE SF is operated as FP.
2.7 BATTERY MANAGEMENT
Figure 6 shows a handset application with NiMH. SOC
(State Of Charge) is used to measure the amount of
charge in the rechargeable batteries.
Figure 7 shows an FP application. The FP uses an
external LDO, so the SOC pins are not used and can
be connected to GND.
The SOC circuit is used to very accurately determine
the amount of charge in rechargeable batteries as well
as the discharge state of Alkaline batteries. This infor-
mation is essential for the battery charging algorithm
and necessary for battery status indication to the user.
Detailed information can be found in AN-D-174 (see
Reference [2]).
Pin CHARGE_CTRL is driven high when either
“sensed voltage on the VBAT pin” is lower than the
voltage setting (defined by the module hardware) or
“sensed current via SOCp” is lower than the current
setting (defined by the module hardware). Pin
CHARGE_CTRL can drive up to 500 A as source cur-
rent (see Table 19).
2.8 EMBEDDED QSPI FLASH
The SC14SPNODE SF has a QSPI FLASH with type
number MX25U1635E as embedded FLASH. Please
refer to Reference [3] for detailed specifications.
The MX25U1635E has an OTP area, a part of which
has already been factory programmed by Dialog for
tuning purposes.
Table 2 shows the production parameters and the rela-
tion between the SC14SPNODE SF register address
and the OTP address.
The OTP addresses from 0x020 to 0x1FF are available
for write access before locking the OTP.

4.0 Design guidelines
4.1 PCB DESIGN GUIDELINES
• Because of the presence of the digital radio fre-
quency burst with 100 Hz time division periods (TDD
noise), supply ripple and RF radiation, special atten-
tion is needed for the power supply and ground PCB
layout.
• Power supply considerations
Both high and low frequency bypassing of the supply
line connections should be provided and placed as
close as possible to the SC14SPNODE. In order to
get the best overall performance for both FP and PP
applications, a number of considerations for the PCB
has to be taken into account.
• Make angle breaks on long supply lines to avoid
resonances at DECT frequencies. Maximum
80 mm before an angle break is recommended.
• Supply lines should be placed as far as possible
away from sensitive audio circuits. If it is neces-
sary to cross supply lines and audio lines, it
should be done with right angles between supply
and audio lines/circuits (microphone, ear-speaker,
speakerphone, etc.)
• Ground plane considerations
In order to achieve the best audio performance
and to avoid the influence of power supply noise,
RF radiation, TDD noise and other noise sources,
it is important that the audio circuits on both FP
and PP applications boards are connected to the
VREFM pin on the SC14SPNODE with separate
nets in the layout.
It is advised to provide the following audio circuits
with separate ground nets connected to the
VREFM pin:
• Microphone(s)
• Headset microphone and speaker
• Speakerphone (signal grounds)
Depending on the layout it may also be necessary to
bypass a number of the audio signals listed above to
avoid humming, noise from RF radiation and TDD
noise. It is also important to choose a microphone of
appropriate quality with a high RF immunity (with built-
in capacitor).
• ESD performance
Besides TDD noise, the ESD performance is impor-
tant for the end-application. In order to achieve a
high ESD performance supply lines should be
placed with a large distance from charging terminals,
display, headset connector and other electrical ter-
minals with direct contact to the ESD source.
On a two-layer PCB application it is important to
keep a simulated one layer ground. With a stable
ground ESD and TDD noise performance will always
improve.
• Clearance around test patterns
Pin number 81 to 88 are used for production test
purposes. In order to avoid any interference or dis-
turbance the area around these signal pins must be
kept clear of any signal and/or GND. The recom-
mended clearance is at least 1 mm as shown in Fig-
ure 15.

4.2 MODULE PLACEMENT ON THE MAIN BOARD
In order to ensure FCC compliance, proper coverage
and to avoid detuning of the antennas, it is required to
place the module on the main board free from other
surrounding materials.
Keep a distance of at least 10 mm from the antenna
elements to conducting objects and at least 5 mm to
non-conducting objects.
Keep in mind that electrical shielding objects, even
partly surrounding the antennas, will normally cause a
significant degradation of the coverage.
Place the module at the edge of the main-board as
shown in Figure 16.
If the module has to be placed away from the edge of
the main-board, then avoid conducting areas in front of
the antennas and make a cut-out in the main board
underneath the antennas as shown in the figure.
See Figure 18 and Figure 21 for the detailed package
outline.
4.3 PATTERN FOR PIN 79 ON THE MAIN BOARD
The copper pattern for pin 79 on the main board is very
important because it is part of the internal antenna of
the module. It is used to extend the internal antenna for
optimum RF performance.
The PCB pattern shown in Figure 19 under “pads C”
for pin 79 on the main board was used during module
certification.
4.4 PRECAUTIONS REGARDING UNINTENDED
COUPLING
The SC14SPNODE includes an internal antenna, so by
integration on the main board precautions shall be
taken in order to avoid any kind of coupling from the
main board to the RF part of the module.
If there is any doubt about this, a brief radio test should
be performed.
