3. Detailed Interface Specifications Note: If not specified, all electrical values are given for VBATT=3.7V and an operating temperature of 25°C. For standard applications, VBATT and VBATT_PA must be tied externally to the same power supply. For some specific applications, AirPrime HL6528x module supports separate VBATT and VBATT_PA connection if requirements below are fulfilled. 3.1. Power Supply The AirPrime HL6528x module is supplied through the VBATT signal with the following characteristics.

VGPIO The VGPIO output can be used to: Pull-up signals such as I/Os Supply the digital transistors driving LEDs Act as a voltage reference for the ADC interfaces, ADC0 and ADC1 The VGPIO output is available when the AirPrime HL6528x module is switched ON. Table 10.
Product Technical Specification Detailed Interface Specifications 3.4. BAT_RTC The AirPrime HL6528x module provides an input/output to connect a Real Time Clock power supply. This pin is used as a back-up power supply for the internal Real Time Clock. The RTC is supported when VBATT is available but a back-up power supply is needed to save date and hour when VBATT is switched off. If VBATT is available, the back-up battery can be charged by the internal 3.0V power supply regulator. Table 11.
Product Technical Specification 3.5.1.1. Detailed Interface Specifications UIM1_DET UIM1_DET is used to detect and notify the application about the insertion and removal of a UIM device in the UIM socket connected to the main UIM interface (UIM1). When a UIM is inserted, the state of UIM1_DET transitions from logic 0 to logic 1. Inversely, when a UIM is removed, the state of UIM1_DET transitions from logic 1 to logic 0. The GPIO for UIM1_DET is GPIO3.. 3.5.2.

Product Technical Specification Detailed Interface Specifications 3.8. Power On Signal (PWR_ON) A low level signal has to be provided to switch the AirPrime HL6528x module ON. It is internally connected to the permanent 3.0V supply regulator inside the HL6528x via a pull-up resistor. Once VBATT is supplied to the HL6528x module, this 3.0V supply regulator will be enabled and so PWR_ON signal is by default at high level. The PWR_ON signal’s characteristics are listed in the table below. Table 17.
Product Technical Specification Detailed Interface Specifications 3.9. Reset Signal (RESET) To reset the module, a low level pulse must be sent on RESET pin for at least 10ms. This action will immediately restart the AirPrime HL6528x module. It is therefore useless to perform a new ignition sequence (PWR_ON) afterwards. As RESET is internally pulled up, a simple open collector or open drain transistor can be used to control it.
Product Technical Specification Detailed Interface Specifications 3.11.1. Analog Audio Input The microphone input can either have a single-ended or a differential connection. However, performance with common mode noise and TDMA noise varies depending on the connection mode and PCB layout. When connecting a microphone to the AirPrime HL6528x module, ensure to have a very good ground plane, very good filtering as well as shielding in order to avoid any disturbance on the audio path.
Product Technical Specification Detailed Interface Specifications Characteristic Value Sensitivity (S.P.L) >105 dB at 1KHz with IEC318 coupler Distortion 5% max at 1K Hz, nominal input power 3.12. PCM The Digital Audio Interface (PCM) interface allows connectivity with standard audio peripherals. It can be used, for example, to connect an external audio codec. The programmability of this interface allows addressing a large range of audio peripherals.

EXT_LNA_GPS_EN (HL6528-G and HL6528G2.8V only) EXT_LNA_GPS_EN ON indicates whether the GNSS receiver is active and can be used to enable an external LNA (or active antenna), especially during GNSS low power mode.

Product Technical Specification Detailed Interface Specifications Refer to the following table for the status of the 2G_TX_ON signal depending on the embedded module’s state. Table 29. Burst Indicator States Embedded Module State 2G_TX_ON During TX burst High No TX Low During TX burst, there is a higher current drain from the VBATT_PA power supply which causes a voltage drop. This voltage drop from VBATT_PA is a good indication of a high current drain situation during TX burst.

5. Design Guidelines 5.1. Power-Up Sequence Apply a LOW level logic to the PWR_ON pin (pin 59). When CTS is toggling to low level, the module is ready to receive AT commands. Figure 12. UART Signals during the Power ON Sequence 5.2. Module Switch-Off AT command AT*PSCPOF enables the user to properly switch the AirPrime HL6528x module off. If required, the module can be switched off by controlling the power supply.
Product Technical Specification Design Guidelines 5.3. Sleep Mode Management AT command AT+KSLEEP enables the sleep mode configuration. AT+KSLEEP=0: The AirPrime HL6528x module is active when DTR signal is active (low electrical level). When DTR is deactivated (high electrical level), the AirPrime HL6528x module enters sleep mode after a while. On DTR activation (low electrical level), the AirPrime HL6528x module wakes up.

Example of a MIC Input Connection with LC Filter The LC filter (L1, L2, C2, C3, and C4) is used to reduce EMI perturbation created by TDMA noise, but it is not mandatory.

Single-Ended Connection Example When a single-ended connection is used for MIC, MIC_N is just left open. HL6528x 2.4V Typ. Internal MIC Bias Z2*=2.
Product Technical Specification Design Guidelines The capacitor C1 is highly recommended to eliminate TDMA noise, and it must be placed close to the microphone. Refer to the table below for the recommended components to use with a single-ended microphone connection. Table 36.
Product Technical Specification 5.5.2.1.2. Design Guidelines SPKR Single-Ended Connection C1 SPEAKER Z hp SPKR_P C3 33pF~100pF SPKR_N 18pF HL6528x Figure 20. Example of a Single-Ended Speaker Connection (typical implementation) In a single-ended connection: 4.7µF < C1 < 47µF, depending on the speaker characteristics and output power the connection between the AirPrime HL6528x module pins and the speaker must be designed to keep the serial impedance lower than 1.
Product Technical Specification Design Guidelines Figure 22. Differential Audio Connection For single-ended connections, the negative pole of the microphone, MIC_N, should be connected to GND. Refer to the following figure. Figure 23. Single-Ended Audio Connection Caution: Avoid digital tracks crossing under and over the audio tracks. It is highly recommended to have the MIC ground and the LC filter ground to act as an audio analog ground during the PCB layout.
Product Technical Specification Design Guidelines 5.6. Radio Integration 5.6.1. RF Routing Recommendations To route the RF antenna signals, the following recommendations must be observed for PCB layout: The RF signals must be routed using traces with a 50 characteristic impedance. Basically, the characteristic impedance depends on the dielectric constant (εr) of the material used, trace width (W), trace thickness (T), and height (H) between the trace and the reference ground plane.
Product Technical Specification Design Guidelines Poor routing Correct routing The yellow traces cross the RF trace. There is no signal around the RF path. Figure 25. RF Routing Examples Fill the area around the RF traces with ground and ground vias to connect inner ground layers for isolation. Cut out ground fill under RF signal pads to reduce stray capacitance losses. Avoid routing RF traces with sharp corners. A smooth radius is recommended. E.g. Use of 45°angles instead of 90°.
Product Technical Specification Design Guidelines Figure 27. Antenna Microstrip Routing Example 5.6.2. GSM Antenna Integration with Antenna Detection Circuitry The AirPrime HL6528x module is equipped with external antennas. A 50Ω line matching circuit between the module, the customer’s board and the RF antennas is required, for GSM and GPS feed path, as shown in the example below. Figure 28. GSM Antenna Connection with Antenna Detection Note: 4114016 Antenna detection circuit is optional.
Product Technical Specification Design Guidelines 5.6.3. GNSS Active Antenna Integration The AirPrime HL6528-G and HL6528-G2.8V modules embed a GPS/GLONASS receiver inside. A possible implementation with an active GNSS antenna is defined below. Figure 29. GNSS Application with Active Antenna EXT_LNA_GPS_EN is a specific signal that automatically sets the AirPrime HL6528-G and HL6528G2.8V modules’ internal LNA to low gain when an external pull-down resistor is detected.
6. X-Ray Exposure X-ray exposure results in an undesirable shift in programmed bit threshold voltage of the Flash memory. As a result, Sierra Wireless recommends avoiding any X-ray exposure during customer manufacturing process to ensure software integrity and long term reliability.
