Fig4-1 is the optimum cost solution, requiring 11 IO ports; Fig4- 2 is the minimum IO ports solution, requiring 8 IO ports. Fig4-1 optimum cost solution Fig4-2 minimum IO ports solution Antenna Antenna HYLINTECH 杭 州 海 联 物 联 科 技有限公司 7 / 8 4.2 PCB Layout Notes 1． The DIO port is connected to the MCU's IO port with external interrupt. 2． The Trace between the RF port and the antenna is as short as possible. the RF Trac should be impedance matched (50Ω). 3． Add π-matching circuit between RF port and antenna if possible. 4． Keep the antenna away from other devices. 5． Keep away from high voltage circuits and high frequency circuits. 6． Ensure the quality of grounding, it is best to ensure a large area of paving. 4.3 SPI Interface The SPI interface gives access to the configuration register via a synchronous full-duplex protocol corresponding to CPOL = 0 and CPHA = 0 in Motorola/Freescale nomenclature. Only the slave side is implemented. An address byte followed by a data byte is sent for a write access whereas an address byte is sent and a read byte is received for the read access. The NSS pin goes low at the beginning of the frame and goes high after the data byte. MOSI is generated by the master on the falling edge of SCK and is sampled by the slave (i.e. this SPI interface) on the rising edge of SCK. MISO is generated by the slave on the falling edge of SCK. A transfer is always started by the NSS pin going low. MISO is high impedance when NSS is high. The SPI runs on the external SCK clock to allow high speed up to 16MHz. For detailed information, please refer to the LLCC68 chip instruction manual. Fig4-3 SPI Timing Diagram HYLINTECH 杭 州 海 联 物 联 科 技有限公司 8 / 8 5 Additional Notes 5.1Power Supply It is recommended to use a DC regulated power supply to power the HLM9S82 while keeping the power ripple as low as possible. HLM9S82 should be reliably grounded and the positive and negative terminals of the power supply should be properly connected, as reversing the connection may cause permanent damage to the module. 5.2 ESD The module can pass the electrostatic test of contact discharge 4KV and air discharge 8KV. During air discharge, the arc is approximately 10cm from the module. To avoid permanent damage to the device, all necessary ESD precautions should be taken. 5.4 Avoid using some frequencies Since the HLM9S82 uses a 32MHz crystal, crystal'frequency is 902.3-927.7MHz. Users should avoid these frequencies (>1MHz) when using the HLM9S82.
