The pin assignment enables a direct interface to the REB-CBB [2]. Further, the interface connects to the Atmel STK500/501 microcontroller development platform to enable support for various Atmel 8-bit AVR® microcontrollers. The REB212BSMA is preconfigured to interface to an STK501 with an Atmel ATmega1281 or a REB-CBB with an Atmel ATxmega 256A3 respectively. To operate the REB212BSMA with an Atmel ATmega644 on STK500, the 0Ω resistors R10 through R18 must be removed and re-installed on the board manually as resistors R20 through R28 (see Appendix A). Other microcontroller development platforms need to be interfaced using a special adapter board. 4.1.1 Atmel ATmega1281 Configuration Table 4-1 lists the pin assignment of the ATmega1281 configuration (shipping default).

Information about the board, the node MAC address and production calibration values are stored here. A serial EEPROM AT25010B [3] with 128 × 8-bit organization and SPI bus is used because of its small package and low-voltage and low-power operation. The SPI bus is shared between the EEPROM and the transceiver. The select signal for each SPI slave (EEPROM, radio transceiver) is decoded with the reset line of the transceiver, RSTN. Therefore, the EEPROM is addressed when the radio transceiver is held in reset (RSTN = 0; see Figure 4-2). Figure 4-2. EEPROM Access Decoding Logic (Atmel ATmega1281 Configuration) The EEPROM data is written during board production testing. A unique serial number, the MAC address, and calibration values are stored. These can be used to optimize system performance. Table 4-3 shows a detailed description of the EEPROM data structure. Table 4-3.

The current consumption of all circuitry connected to the supply domains DEVDD/EVDD such as AT86RF212B and AT25010B can be measured by connecting an ampere meter instead of the jumper cap JP1, see Figure 4-3. The power supply pins of the radio transceiver are protected against overvoltage and reverse polarity at the X1 connector pins (net CVTG, net DGND) using a Zener diode, D1, and a thermal fuse, F1, (see Appendix A). This is required because the Atmel STK500 will provide 5V as default voltage, and the board can also be mounted with reverse polarity. Depending on the actual supply voltage, the diode D1 can consume several milliamperes. This has to be considered when the current consumption of the whole system is measured. In such a case, D1 should be removed from the board. To achieve the best RF performance, the analog (EVDD) and digital (DEVDD) supply are separated from each other by a CLC PI-filter.
AT02876: Atmel REB212BSMA Hardware User Manual [APPLICATION NOTE] Atmel-42097B-WIRELESS-AT02876-REB212BSMA-Hardware-User-Manual_ApplicationNote_062014 8 All components connected to nets DEVDD/EVDD contribute to the total current consumption. While in radio transceiver SLEEP state, most of the supply current is drawn by the 1MΩ pull-up resistor R21 and the EEPROM standby current. Figure 4-3. Power Supply Routing 4.4 Radio Transceiver Reference Clock The integrated radio transceiver is clocked by a 16MHz reference crystal, Q1. Operating the node according to IEEE 802.15.4 [4], the reference frequency must not exceed a deviation of ±40ppm. The absolute frequency is determined by the external load capacitance of the crystal, which depends on the crystal type and is given in its datasheet. The radio transceiver reference crystal, Q1, shall be isolated from fast switching digital signals and surrounded by a grounded guard trace to minimize disturbances of the oscillation. Detailed layout considerations can be found in Section 5.2. The REB212BSMA uses a Siward SX4025 crystal with two load capacitors of 10pF each. To compensate for fabrication and environment variations, the frequency can be further tuned using the radio transceiver register XOSC_CTRL (0x12), refer to [1]. The REB production test guarantees a tolerance of within +20ppm and -5ppm. The correction value, to be applied to TRX register XOSC_CTRL (0x12), is stored in the ID EEPROM, see Section 4.2. The reference frequency is also available at pin CLKM of the radio transceiver and, depending on the related register setting; it is divided by an internal prescaler. The CLKM signal is filtered by a low-pass filter to reduce harmonic emissions within the 868 / 915MHz ISM band. The filter is designed to provide a stable 1MHz clock signal with correct logic level to a microcontroller pin with sufficiently suppressed harmonics. Usage of CLKM frequencies above 1MHz requires a re-design of R25 and C40. In case of RC cut-off frequency adjustments, depending on the specific load and signal routing conditions, one may observe performance degradation within affected IEEE channels. Channel 4 (912MHz) is affected by the following harmonics: 57 × 16MHz or 114 × 8MHz. By default, CLKM is routed to a microcontroller timer input; check the individual configuration resistors in the schematic drawing (see Appendix A.1). To connect CLKM to the microcontroller main clock input, assemble R3 with a 0Ω resistor. 4.5 RF Section The Atmel AT86RF212B radio transceiver incorporates all RF and base band critical components, necessary to transmit and receive signals according to IEEE 802.15.4 or proprietary ISM data rates. The balun B1 performs the differential to single-ended conversion of the RF signal to connect the AT86RF212B to the SMA connector X2.
AT02876: Atmel REB212BSMA Hardware User Manual [APPLICATION NOTE] Atmel-42097B-WIRELESS-AT02876-REB212BSMA-Hardware-User-Manual_ApplicationNote_062014 9 To estimate the effective output power for the SMA connector reference plane, insertion losses of the balun and the transmission line have to be taken into account. Therefore, the SMA connector output power can be up to 1.5dB below the AT86RF212B datasheet value, according to specification of the balun. Insertion loss data for the individual components can be obtained from associated datasheets. Please check the part reference inside the BOM in Appendix A.3. 5 PCB Layout Description This section describes critical layout details to be carefully considered during a PCB design. The PCB design requires taking care of the following topics: • Create a solid ground plane as a stable reference for the transceiver, the antenna and the transmission lines. The PCB has to be considered as a part of the antenna; it interacts with the radiated electromagnetic wave • Isolate digital noise from the antenna and the radio transceiver to achieve optimum range and RF performance • Isolate digital noise from the 16MHz reference crystal to achieve optimum transmitter and receiver performance • Reduce any kind of spurious emissions below the limits set by the individual regulatory organizations The REB212BSMA PCB design further demonstrates a low-cost, two-layer PCB solution without the need of an inner ground plane. 5.1 Balanced RF Pin Fan Out Figure 5-1. Board Layout – RF Pin Fan Out The Atmel AT86RF212B antenna port should be connected to a 100Ω load with a small series inductance of app. 3nH. This is achieved with the connection fan out in between the IC pins and the filter balun combination B1. The trace width is kept small at 0.15mm for a length of approximately 2.5mm. The REB212BSMA is a two-layer FR4 board with a thickness of 1.5mm. Therefore, the distributed capacitance between top and bottom is low, and transmission lines are rather inductive. The distance between balun and transceiver also allows GND vias for pin 3 and pin 6 of the AT86RF212B. The GND connection in a low distance has a small parasitic inductance and is therefore desirable for the RF port.
AT02876: Atmel REB212BSMA Hardware User Manual [APPLICATION NOTE] Atmel-42097B-WIRELESS-AT02876-REB212BSMA-Hardware-User-Manual_ApplicationNote_062014 10 5.2 Crystal Routing The reference crystal PCB area requires optimization to minimize external interference and to keep any radiation of 16MHz harmonics low. Since the board design incorporates a shield, the crystal housing has been tied hard to ground. This method will minimize the influence of external impairments such as burst and surge. To prevent crosstalk, the crystal is encircled by a ring of ground traces and vias. Special care has to be taken in the area between the IRQ line and the crystal. Depending on the configuration, the interrupt may be activated during a frame receive. Crosstalk into the crystal lines would increase the phase noise and therefore reduce the signal to noise ratio. Figure 5-2. Board Layout – Crystal Routing The reference crystal and its load capacitors C37/38 form the resonator circuit. These capacitors are to be placed close to the crystal. The ground connection in between the capacitors should be a solid copper area right underneath the crystal, including the housing contacts. 5.3 Transceiver Analog GND Routing With the Atmel AT86RF212B, consider pins 3, 6, 27, 30, 31, and 32 as analog ground pins. Pin 7 is an exception and can be connected to the central paddle like the other analog ground pins. Analog ground pins are to be routed to the paddle underneath the IC. The trace width has to be similar to the pad width when connecting the pads, and increase, if possible, in some distance from the pad. This measure will decrease the parasitic inductance as far as possible. Each ground pin should be connected to the bottom plane with at least one via. Move the vias as close to the IC as possible. It is always desired to integrate the single-pin ground connections into polygon structures after a short distance. Top, bottom, and, on multilayer boards, the inner ground planes, should be tied together with a grid of vias. When ground loops are smaller than one tenth of the wavelength, it is safe to consider this as a solid piece of metal.
AT02876: Atmel REB212BSMA Hardware User Manual [APPLICATION NOTE] Atmel-42097B-WIRELESS-AT02876-REB212BSMA-Hardware-User-Manual_ApplicationNote_062014 11 Figure 5-3. Board Layout – Transceiver GND Routing The soldering technology used allows the placement of small vias (0.15mm drill) within the ground paddle underneath the chip. During reflow soldering, the vias get filled with solder, having a positive effect on the connection cross section. The small drill size keeps solder losses within an acceptable limit. During the soldering process vias should be open on the bottom side to allow enclosed air to expand. 5.4 Digital GND Routing and Shielding With the Atmel AT86RF212B, consider pins 12, 16, 18, and 21 as digital ground pins. Digital ground pins are not directly connected to the center paddle. They may carry digital noise from I/O pad cells or other digital processing units within the chip. In case of a direct paddle connection, impedances of the paddle ground vias could cause a small voltage drop for this noise and may result in an increased noise level transferred to the analog domain. There is a number of pro’s and con’s when it comes to the shielding topic. The major con’s are: • Cost of the shield • Manufacturing effort • Inaccessibility for test and repair The number of pro’s might be longer but the cost argument is often very strong. However, the reasons to add the shield for this reference design are: • Shield is required for a certification in Japan • Shield is recommended for FCC certification in North America • Increased performance Besides the function to provide supply ground to the individual parts, the ground plane has to be considered as a counterpart for the antenna. Such an antenna base plate is required to achieve full antenna performance. It has to be a continuous, sustained metal plate for that purpose. The shield, covering the electronic section will help to form this antenna base plate. For that reason, any unused surface should be filled with a copper plane and connected to the other ground side using sufficient through-hole contacts. Larger copper areas should also be connected to the other side layer with a grid of vias. This will form kind of a RF sealing for the PCB material. Any wave propagation in between the copper layers across the PCB will become impossible. This way, for an external electromagnetic field, the board will behave like a coherent piece of metal.
AT02876: Atmel REB212BSMA Hardware User Manual [APPLICATION NOTE] Atmel-42097B-WIRELESS-AT02876-REB212BSMA-Hardware-User-Manual_ApplicationNote_062014 12 When a trace is cutting the plane on one side, the design should contain vias along this trace to bridge the interrupted ground on the other side. Place vias especially close to corners and necks to connect lose polygon ends. The pads where the shield is mounted also need some attention. The shield has to be integrated in the ground planes. Vias, in a short distance to the pads, will ensure a low impedance connection and also close the FR4 substrate as mentioned above. 6 Mechanical Description The REB212BSMA is manufactured using a low-cost, two-layer printed circuit board. All components and connectors are mounted on the top side of the board. The format was defined to fit the EXPAND1 connector on the Atmel AVR STK500/STK501 microcontroller evaluation board. The upright position was chosen for best antenna performance. Figure 6-1. Mechanical Dimensions
