Note:

Restrictions for the Power States
When VDDIO is off (either disconnected or at ground potential), a voltage must not be applied to the device pins.
This is because each pin contains an ESD diode from the pin to the VDDIO supply. This diode will turn on when a
voltage higher than one diode-drop is supplied to the pin. This, in turn, will try to power up the part through the
VDDIO supply.
If a voltage must be applied to the signal pads while the chip is in a low power state, the VDDIO supply must be
on.
Similarly, to prevent the pin-to-ground diode from turning on, do not apply a voltage that is more than 0.3V below
ground to any pin.

RTC Pins
Module pins 25 and 27 (RTC_CLKP and RTC_CLKN, respectively) are used for a 32.768kHz crystal. To be
compliant with the BLE specifications for connection events, the frequency accuracy of this clock has to be within
±500ppm. Because of the high accuracy of the 32.768kHz crystal oscillator clock (±25ppm), the power
consumption can be minimized by leaving radio circuits in low power sleep mode for as long as possible until they
need to wake up for the next connection timed event.
The block diagram in Figure 5-2(a) shows how the internal low-frequency Crystal Oscillator (XO) is connected to
the external crystal.
Typically, the crystal should be chosen to have a load capacitance of 7pF to minimize the oscillator current. The
ATSAMB11-MR210CA device has switchable on chip capacitance that can be used to adjust the total load the
crystal sees to meet its load capacitance specification. Refer to the ATSAMB11-2100A datasheet for more
information.
Alternatively, if an external 32.768kHz clock is available, it can be used to drive the RTC_CLKP pin instead of
using a crystal. The XO has 5.625F internal capacitance on the RTC_CLKP pin. To bypass the crystal oscillator an
external signal capable of driving 5.625pF can be applied to the RTC_CLK_P terminal as shown in Figure 5-2(b).
This signal must be 1.2V maximum. RTC_CLK_N must be left unconnected when driving an external source into
RTC_CLK_P.

Application Schematic
The ATSAMB11-MR210/MR510CA modules are fully self-contained. To use the module, just provide VBAT and
VDDIO supplies. Figure 7-1 and Figure 7-2 shows a typical design using the ATSAMB11-MR210/MR510CA
modules. The schematic shows several host interfaces: UART, I2C, and SPI as well as an input to the ADC on the
GPIO_MS1 pin. A user can choose the interface(s) required for their application. If a 32.768kHz Real Time Clock is
not available in the system, a 32.768kHz crystal can be used. Section 7.2 shows a design using a crystal for the
Real Time Clock. The crystal should be specified with a load capacitance, CL=7pF and a total frequency error of
200ppm. Table 7-1 shows the BOM for the application schematics.
Note: The UART RTS and UART CTS are used for hardware flow control; they MUST be connected to the host
MCU UART and enabled for the UART interface to be functional.
Module design information such as module schematics can be obtained under an NDA from Atmel.

Placement and Routing Guidelines
It is critical to follow the recommendations listed below to achieve the best RF performance:
1. The board should have a solid ground plane. The center ground pad of the device must be soldered to the
ground plane by using a 3 x 3 grid of vias (see Figure 4-2). Each ground pin of the ATSAMB11-MR210CA
should have a ground via placed either in the pad or right next to the pad going down to the ground plane.
2. When the module is placed on the customer PCB design, a provision for the antenna must be made. There
should be nothing under the portion of the module, which contains the antenna. This means the antenna
should not be placed directly on top of the customer PCB as shown in Figure 8-1(a). This can be
accomplished by, for example, placing the module at the edge of the board such that the module edge with
the antenna extends beyond the customer PCB edge by 6.5mm as shown in Figure 8-1 (b). Alternatively, a
cutout in the customer PCB can be provided under the antenna. The cutout should be at least 22mm x
6.5mm (see Figure 8-1 (c) and Figure 8-2). If the cutout method is used, the SAMB11-MR210CA should be
centered in the cutout. The SAMB11-MR210CA must have ground vias spaced 2.5mm apart that should be
placed all around the perimeter of the cutout. No large components should be placed near the antenna.
3. Keep away from antenna, as far as possible, large metal objects to avoid electromagnetic field blocking
4. Do not enclose the antenna within a metal shield
5. Keep any components that may radiate noise or signals within the 2.4GHz – 2.5GHz frequency band far
away from the antenna or better yet, shield the components that are generating the noise. Any noise
radiated from the customer PCB in this frequency band will degrade the sensitivity of the SAMB11-
MR210CA module.

8.1
Power and Ground
Dedicate one layer as a ground plane. Make sure that this ground plane does not get broken up by routes. Power
can route on all layers except the ground layer. Power supply routes should be heavy copper fill planes to ensure
the lowest possible inductance. The power pins of the module should have a via directly to the power plane as
close to the pin as possible. Decoupling capacitors should have a via right next to the capacitor pin and this via
should go directly down to the power plane – that is to say, the capacitor should not route to the power plane
through a long trace. The ground side of the decoupling capacitor should have a via right next to the pad which
goes directly down to the ground plane. Each decoupling capacitor should have its own via directly to the ground
plane and directly to the power plane right next to the pad. The decoupling capacitors should be placed as close to
the pin that it is filtering as possible.
8.2
Interferers
One of the biggest problems with RF receivers is poor performance due to interferers on the board radiating noise
into the antenna or coupling into the RF traces going to input LNA. Care must be taken to make sure that there is
no noisy circuitry placed anywhere near the antenna or the RF traces. All noise generating circuits should also be
shielded so they do not radiate noise that is picked up by the antenna. Also, make sure that no traces route
underneath the RF portion of the SAMB11-MR210CA. Also, make sure that no traces route underneath any of the
RF traces from the antenna to the SAMB11-MR210CA input. This applies to all layers. Even if there is a ground
plane on a layer between the RF route and another signal, the ground return current will flow on the ground plane
and be coupled into the RF traces.

Reflow Profile Information
This section provides guidelines for reflow processes in getting the Atmel module soldered to the customer’s
design.
9.1
Storage Conditions
9.1.1 Moisture Barrier Bag Before Opened
A moisture barrier bag must be stored in a temperature of less than 30°C with humidity under 85% RH.
The calculated shelf life for the dry-packed product shall be 12 months from the date the bag is sealed.
9.1.2 Moisture Barrier Bag Open
Humidity indicator cards must be blue, <30%.
9.2
Stencil Design
The recommended stencil is laser-cut, stainless-steel type with a thickness of 100µm to 130µm and approximately
a 1:1 ratio of stencil opening to pad dimension. To improve paste release, a positive taper with bottom opening
25µm larger than the top can be utilized. Local manufacturing experience may find other combinations of stencil
thickness and aperture size to get good results.
9.3
Baking Conditions
This module is rated at MSL level 3. After sealed bag is opened, no baking is required within 168 hours so long as
the devices are held at ≤30°C/60% RH or stored at <10% RH.
The module will require baking before mounting if:
The sealed bag has been open for >168 hours
Humidity Indicator Card reads >10%
SIPs need to be baked for 8 hours at 125°C
9.4
Soldering and Reflow Condition
9.4.1 Reflow Oven
It is strongly recommended that a reflow oven equipped with more heating zones and Nitrogen atmosphere be
used for lead-free assembly. Nitrogen atmosphere has shown to improve the wet-ability and reduce temperature
gradient across the board. It can also enhance the appearance of the solder joints by reducing the effects of
oxidation.
The following items should also be observed in the reflow process:
1. Some recommended pastes include:
–
–
NC-SMQ® 230 flux and Indalloy® 241 solder paste made up of 95.5 Sn/3.8 Ag/0.7 Cu
SENJU N705-GRN3360-K2-V Type 3, no clean paste.
2. Allowable reflow soldering iterations:
Three times based on the following reflow soldering profile (as shown in Figure 9-1).
3. Temperature profile:
–
–
–
Reflow soldering shall be done according to the following temperature profile (as shown in Figure 9-1).
Peak temperature: 250°C.

Module Assembly Considerations
The ATSAMB11-MR210 and ATSAMB11-MR510 modules are assembled with an EMI Shield to ensure
compliance with EMI emission and immunity rules. The EMI shield is made of a tin-plated steel (SPTE) and is not
hermetically sealed. Solutions like IPA and similar solvents can be used to clean the ATSAMB11-MR210 or
ATSAMB11-MR510. However, cleaning solutions, which contain acid, should never be used on the module.
The ATSAMB11-MR210 and ATSAMB11-MR510 modules are manufactured without any conformal coating
applied. It is the customer’s responsibility if a conformal coating is specified and applied to the ATSAMB11-MR210
or ATSAMB11-MR510 module.

12 Errata
Issue:
In the ATSAMB11 Datasheet, the measured advertisement current for the cases listed in Table 6-
3 will be higher than what is reported.
SDK5.0 does not resemble the same conditions where Table 6-3 has been measured.
For example:
The power and timing parameters in the SDK5.0 release have not been fully optimized to their
final values
IDRAM1 and IDRAM2 are always enabled/retained for ROM patches and application
development
SDK5.0 enables clocks to different peripheral blocks to allow easier application development
Continuous access to the SWD debug interface is needed. Therefore, debug clocks cannot be
turned OFF.
A small sample measurement has been performed they show the following results:
Measurement condition:
1-sec advertising interval
37 byte advertising payload
Connectable beacon
