Used for AT command communication and data transmission. By default, the module is in auto-baud mode, and it supports automatic baud rates not exceeding 115200bps. When powering on the module, the MCU has to send AT command consecutively to synchronize baud rate with the module. When OK is returned, it indicates the baud rate has been synchronized successfully. When the module is woken up from PSM or idle mode, the baud rate synchronized during start-up will be used directly. Also can be used for firmware upgrade, and in such case, the baud rate is UART Interfaces 921600bps by default. Debug UART Port:

* means under development. 3.4. Operating Modes The following table briefly describes the three operating modes of the module. Table 5: Overview of Operating Modes Mode Function Normal Operation Active Idle In active mode, all functions of the module are available and all processors are active; radio transmission and reception can be performed. Transitions to idle mode or PSM can be initiated in active mode. In idle mode, the module is in light sleep and network connection is maintained in DRX/eDRX state; paging messages can be received. Transitions to active mode or PSM can be initiated in idle mode. BC66_Hardware_Design 18 / 57 NB-IoT Module Series BC66 Hardware Design PSM In PSM, only the 32kHz RTC is working, and the network is disconnected. The module will exit from PSM and enter into active mode when the timer T3412 times out, and it can also be woken up from PSM by PSM_EINT. For more details, please refer to Chapter 3.5. 3.5. Power Saving Mode (PSM) Based on system performance, the module consumes an ultra-low current (maximally 5A power consumption) in PSM. PSM is designed to reduce power consumption of the module and improve battery life. The following figure shows the power consumption of the module in different modes. Figure 3: Module Power Consumption in Different Modes The procedure for entering PSM is as follows: the module requests to enter PSM in ATTACH REQUEST message during attach/TAU (Tracking Area Update) procedure. Then the network accepts the request and provides an active time value (T3324) to the module and the mobile reachable timer starts. When the T3324 timer expires, the module enters PSM for duration of T3412 (periodic TAU timer). Please note that the module cannot request PSM when it is establishing an emergency attachment or initializing the PDN
(Public Data Network) connection. When the module is in PSM, it cannot be paged and stops access stratum activities such as cell reselection, but T3412 is still active. Either of the following methods can make the module exit from PSM:
After the T3412 timer expires, the module will exit PSM automatically. Pulling down PSM_EINT (falling edge) will wake the module up from PSM. The timing of waking up the module from PSM is illustrated below. BC66_Hardware_Design 19 / 57 NB-IoT Module Series BC66 Hardware Design Figure 4: Timing of Waking up Module from PSM NOTE Among all GPIO interrupts, only the dedicated external interrupt pin PSM_EINT can successfully wake up the module from PSM. The module cannot be woken up by any other general purpose GPIO interrupts. 3.6. Power Supply 3.6.1. Power Supply Pins BC66 provides two VBAT pins for connection with an external power supply. The table below describes the module's VBAT and ground pins. Table 6: Power Supply Pins Pin Name Pin No. VBAT_BB 42 VBAT_RF 43 Description Power supply for the modules baseband part Power supply for the modules RF part 1, 27, 34, 36, 37, 40, 41 GND GND Min. Typ. Max. Unit 2.1 2.1 3.3 3.3 3.63 3.63 V V BC66_Hardware_Design 20 / 57 NB-IoT Module Series BC66 Hardware Design 3.6.2. Reference Design for Power Supply Power design for a module is critical to its performance. It is recommended to use a low quiescent current LDO with output current capacity of 0.5A as the power supply for BC66. A Li-MnO2/2S alkaline battery can also be used as the power supply. The supply voltage of the module ranges from 2.1V to 3.63V. When the module is working, please make sure its input voltage will never drop below 2.1V; otherwise the module will be abnormal. For better power performance, it is recommended to place a 100uF tantalum capacitor with low ESR
(ESR=0.7) and three ceramic capacitors (100nF, 100pF and 22pF) near the VBAT pins.

By default, the module is in auto-baud mode and it supports automatic baud rates not exceeding 115200bps. When powering on the module, the MCU has to send AT command consecutively to synchronize baud rate with the module. When OK is returned, it indicates the baud rate has been synchronized successfully. When the module is woken up from PSM or idle mode, the baud rate synchronized during start-up will be used directly. When the port is used for firmware upgrade, the baud rate is 921600bps by default. The figure below shows the connection between DCE and DTE. Figure 14: Reference Design for Main UART Port 3.8.2.

USIM Interface The module provides a USIM interface compliant to ISO/IEC 7816-3, enabling the module to access to an external 1.8V USIM card. The external USIM card is powered by an internal regulator in the module and supports 1.8V power supply.

Figure 21: Reference Circuit for USIM Interface with a 6-pin USIM Card Connector information of USIM card connector, please visit http://www.amphenol.com or For more http://www.molex.com. In order to enhance the reliability and availability of USIM card in application, please follow the criteria below in USIM circuit design:
Keep the placement of USIM card connector as close as possible to the module. Keep the trace length as less than 200mm as possible. Keep USIM card signals away from RF and VBAT traces. Assure the trace between the ground of module and that of USIM card connector is short and wide. Keep the trace width of ground no less than 0.5mm to maintain the same electric potential. The decouple capacitor between SIM_VDD and GND should be not more than 1F and be placed close to the USIM card connector. To avoid cross talk between SIM_DATA and SIM_CLK, keep them away from each other and shield them separately with surrounded ground. BC66_Hardware_Design 31 / 57 NB-IoT Module Series BC66 Hardware Design In order to offer good ESD protection, it is recommended to add a TVS diode array. For more information of TVS diode, please visit http://www.onsemi.com. The ESD protection device should be placed as close to USIM card connector as possible, and make sure the USIM card signal lines go through the ESD protection device first and then to the module. The 22 resistors should be connected in series between the module and the USIM card connector so as to suppress EMI spurious transmission and enhance ESD protection. Please note that the USIM peripheral circuit should be close to the USIM card connector. Place the RF bypass capacitors (33pF) close to the USIM card connector on all signal traces to improve EMI suppression. 3.11.

* means under development. 4.3. RF Antenna Reference Design BC66 provides an RF antenna pad for external NB-IoT antenna connection. The RF trace on host PCB connected to the modules RF antenna pad should be coplanar waveguide or microstrip, whose characteristic impedance should be close to 50. BC66 comes with ground pads which are next to the antenna pad in order to give a better grounding. In order to achieve better RF performance, it is recommended to reserve a type matching circuit and place the -type matching components (R1/C1/C2) as close to the antenna as possible. By default, the capacitors (C1/C2) are not mounted and a 0 resistor is mounted on R1. BC66_Hardware_Design 35 / 57 NB-IoT Module Series BC66 Hardware Design A reference design of the RF interface is shown as below. Figure 23: Reference Design of NB-IoT Antenna Interface 4.4. Reference Design of RF Layout For users PCB, the characteristic impedance of all RF traces should be controlled as 50. The impedance of the RF traces is usually determined by the trace width (W), the materials dielectric constant, the height between signal layer and reference ground (H), and the clearance between RF trace and ground (S). Microstrip line or coplanar waveguide line is typically used in RF layout for characteristic impedance control. The following are reference designs of microstrip line or coplanar waveguide line with different PCB structures. Figure 24: Microstrip Line Design on a 2-layer PCB BC66_Hardware_Design 36 / 57 NB-IoT Module Series BC66 Hardware Design Figure 25: Coplanar Waveguide Line Design on a 2-layer PCB Figure 26: Coplanar Waveguide Line Design on a 4-layer PCB (Layer 3 as Reference Ground) Figure 27: Coplanar Waveguide Line Design on a 4-layer PCB (Layer 4 as Reference Ground) In order to ensure RF performance and reliability, the following principles should be complied with in RF layout design:
BC66_Hardware_Design 37 / 57 NB-IoT Module Series BC66 Hardware Design Use impedance simulation tool to control the characteristic impedance of RF traces as 50. The GND pins adjacent to RF pins should not be designed as thermal relief pads, and should be fully connected to ground. The distance between the RF pins and the RF connector should be as short as possible, and all the right angle traces should be changed to curved ones. There should be clearance area under the signal pin of the antenna connector or solder joint. The reference ground of RF traces should be complete. Meanwhile, adding some ground vias around RF traces and the reference ground could help to improve RF performance. The distance between the ground vias and RF traces should be no less than two times the width of RF signal traces (2*W). For more details, please refer to document [2]. 4.5. Antenna Requirements To minimize the loss on RF trace and RF cable, please pay attention to the antenna design. The following tables show the requirements on NB-IoT antenna.

It is rated at MSL 3, and storage restrictions are shown as below. 1. Shelf life in the vacuum-sealed bag: 12 months at <40C/90%RH. 2. After the vacuum-sealed bag is opened, devices that will be subjected to reflow soldering or other high temperature processes must be:
Mounted within 168 hours at the factory environment of 30C/60%RH. Stored at <10%RH. 3. Devices require baking before mounting, if any circumstance below occurs. When the ambient temperature is 23C5C and the humidity indication card shows the humidity is >10% before opening the vacuum-sealed bag. Device mounting cannot be finished within 168 hours at factory conditions of 30C/60%. If baking is required, devices may be baked for 8 hours at 120C5C. 4. NOTE As the plastic package cannot be subjected to high temperature, it should be removed from devices before high to temperature (120C) baking. IPC/JEDECJ-STD-033 for baking procedure. is desired, please refer If shorter baking time BC66_Hardware_Design 51 / 57 NB-IoT Module Series BC66 Hardware Design 7.2. Manufacturing and Soldering Push the squeegee to apply the solder paste on the surface of stencil, thus making the paste fill the stencil openings and then penetrate to the PCB. The force on the squeegee should be adjusted properly so as to produce a clean stencil surface on a single pass. To ensure the module soldering quality, the thickness of stencil for the module is recommended to be 0.15mm~0.18mm. For more details, please refer to document [4]. It is suggested that the peak reflow temperature is 240~245C, and the absolute maximum reflow temperature is 245C. To avoid damage to the module caused by repeated heating, it is strongly recommended that the module should be mounted after reflow soldering for the other side of PCB has been completed. The recommended reflow soldering thermal profile (lead-free reflow soldering) and related parameters are shown below. Figure 36: Recommended Reflow Soldering Thermal Profile Table 22: Recommended Thermal Profile Parameters Factor Soak Zone Max slope Recommendation 1 to 3C/sec Soak time (between A and B: 150C and 200C) 60 to 120 sec BC66_Hardware_Design 52 / 57 NB-IoT Module Series BC66 Hardware Design Reflow Zone Max slope Reflow time (D: over 220C) Max temperature Cooling down slope Reflow Cycle Max reflow cycle NOTES 2 to 3C/sec 40 to 60 sec 240C ~ 245C 1 to 4C/sec 1 1.

A certified modular has the option to use a permanently affixed label, or an electronic label. For a permanently affixed label, the module must be labeled with an FCC ID - Section 2.926 (see 2.2 Certification (labeling requirements) above). The OEM manual must provide clear instructions explaining to the OEM the labeling requirements, options and OEM user manual instructions that are required (see next paragraph). For a host using a certified modular with a standard fixed label, if (1) the modules FCC ID is not visible when installed in the host, or (2) if the host is marketed so that end users do not have straightforward commonly used methods for access to remove the module so that the FCC ID of the module is visible;
then an additional permanent label referring to the enclosed module:Contains Transmitter Module FCC ID: XMR201808BC66 or Contains FCC ID: XMR201808BC66 must be used. The host OEM user manual must also contain clear instructions on how end users can find and/or access the module and the FCC ID. The final host / module combination may also need to be evaluated against the FCC Part 15B criteria for unintentional radiators in order to be properly authorized for operation as a Part 15 digital device. The users manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. In cases where the manual is provided only in a form other than paper, such as on a computer disk or over the Internet, the information required by this section may be included in the manual in that alternative form, provided the user can reasonably be expected to have the capability to access information in that form. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
BC66_Hardware_Design 59 / 57 NB-IoT Module Series BC66 Hardware Design
(1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the manufacturer could void the users authority to operate the equipment. To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the Suppliers Declaration of Conformity procedure without a transmitter certified module and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements. IC Statement IRSS-GEN
"This device complies with Industry Canadas licence-exempt RSSs. Operation is subject to the following two conditions: (1) This device may not cause interference; and (2) This device must accept any interference, including interference that may cause undesired operation of the device." or "Le prsent appareil est conforme aux CNR dIndustrie Canada applicables aux appareils radio exempts de licence. Lexploitation est autorise aux deux conditions suivantes :
1) lappareil ne doit pas produire de brouillage; 2) lutilisateur de lappareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible den compromettre le fonctionnement."

The host product shall be properly labeled to identify the modules within the host product. The Innovation, Science and Economic Development Canada certification label of a module shall be clearly visible at all times when installed in the host product; otherwise, the host product must be labeled to display the Innovation, Science and Economic Development Canada certification number for the module, preceded by the word Contains or similar wording expressing the same meaning, as follows:
Contains IC: 10224A-201808BC66 or where: 10224A-201808BC66 is the modules certification number. Le produit hte doit tre correctement tiquet pour identifier les modules dans le produit hte. BC66_Hardware_Design 60 / 57 NB-IoT Module Series BC66 Hardware Design L'tiquette de certification d'Innovation, Sciences et Dveloppement conomique Canada d'un module doit tre clairement visible en tout temps lorsqu'il est installdans le produit hte; sinon, le produit hte doit porter une tiquette indiquant le numro de certification d'Innovation, Sciences et Dveloppement conomique Canada pour le module, prcd du mot Contient ou d'un libell semblable exprimant la mme signification, comme suit:
