JESD22-A114 +/- 1kV Human Body Model JESD22-A115 +/- 200V Machine Model JESD22-C101C +/- 250V Charged Device Model ESD protection is highly recommended at the point where the USIM contacts are exposed, and for any other signals that would be subjected to ESD by the user. Environmental and Certifications 1.9.1. Environmental Specifications The environmental specification for both operating and storage conditions are defined in the table below. Table 4. Environmental Specifications Conditions Range Operating Class A -30°C to +70°C Operating Class B -40°C to +85°C Storage -40°C to +85°C Note: The upper limit of Class A is subject to module PCB temperature. A progressive 3G output power reduction feature is implemented for when PCB temperatures are above +80°C. This leads to a calibrated 3G TX power output up to +80°C for the PCB temperature and automatic decrease at higher temperatures. Therefore, depending on module activity and customer design, the upper limit of Class A could be lower than 70°C. Class A is defined as the operating temperature ranges that the device: Shall exhibit normal function during and after environmental exposure. Shall meet the minimum requirements of 3GPP or appropriate wireless standards. Class B is defined as the operating temperature ranges that the device: Shall remain fully functional during and after environmental exposure Shall exhibit the ability to establish a voice, SMS or DATA call (emergency call) at all times even when one or more environmental constraint exceeds the specified tolerance. Unless otherwise stated, full performance should return to normal after the excessive constraint(s) have been removed. 4117047 Rev 2.2 December 18, 2015 15 Product Technical Specification 1.9.2.

Radio Burst Rates – Connected Mode GSM/GPRS Multislot Class Class 10 Class 12 RF Power Amplifier Current Slot Duration Period Rising Time 2.2A peak 577 μs 4.615 ms 10 μs The corresponding radio burst rates in connected mode are as follows: GSM/GPRS class 2 terminals emit 577 µs radio bursts every 4.615 ms GPRS class 10 terminals emit 1154 µs radio bursts every 4.615 ms GPRS class 12 terminals emit 2308 µs radio bursts every 4.615 ms In connected mode, the RF Power Amplifier current (2.2A peak in GSM /GPRS mode) flows with a ratio of: 1/8 of the time (around 577 µs every 4.615 ms for GSM /GPRS cl 2 – 2RX/1TX), and 4/8 of the time (around 2308 µs every 4.615 ms for GSM /GPRS cl 12 – 4RX/1TX) with the rising time at around 10 µs. Figure 3. 4117047 Power Supply During Burst Transmission Rev 2.2 December 18, 2015 18 Product Technical Specification 2.1.4. Detailed Interface Specifications Power Input (VBATT) An external power supply uses the VBATT pins to: Supply the AirPrime HL8518, HL8528 and HL8529 modules. Directly supply the RF components. It is essential to keep the voltage ripple to a minimum at this connection to avoid any phase error or spectrum modulation degradation. An inadequate power supply can significantly affect RF performance (TX power, modulation spectrum, EMC performance, spurious emission, frequency error, etc.). Provide reference voltage VGPIO (through internal regulators) for the baseband signals. When the AirPrime HL8518, HL8528 and HL8529 modules are supplied with a battery, the total impedance (battery + protections + PCB) should be such that the supply will be >= 3.2 V during GSM burst mode operation drawing a maximum peak current of 2.2 A for 577 µs (one slot) or 1154 µs (two slots) TX. 2.2. Ground Connection The AirPrime HL8518, HL8528 and HL8529 modules shielding case is the grounding. The ground must be connected on the motherboard through a complete layer on the PCB. The ground connection is made by soldering the LGA ground pins and rectangular ground pad to the ground plane of the application board. 2.3. Decoupling of Power Supply Signals The ETSI standard defines specific requirements for phase error and spectrum modulation. Both are mandatory and can be affected by the choice of power supply filtering. It is highly recommended to provide multiple capacitor values to solve an eventual Amplitude and Phase Modulation issue. AirPrime HL8518, HL8528 and HL8529 modules already here embedded decoupling capacitors on the VBATT lines, but additional external decoupling may be required. EMI/RFI issues – Add a capacitor (10pF~33pF) close to the VBATT pins. TDMA noise (217 Hz) – Place a low ESR decoupling capacitors (at least 100 µF) as close to the module as possible to reduce noise.

Main Serial Link (UART1) The main serial link (UART1) is used for communication between the AirPrime HL8518, HL8528 and HL8529 modules and a PC or host processor. It consists of a flexible 8-wire serial interface that complies with RS-232 interface. The supported baud rates of the UART1 are 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800, 500000, 750000, 921600, 1843200, 3000000, 3250000 and 6000000 bit/s. The signals used by UART1 are as follows: TX data (UART1_TX) RX data (UART1_RX) Request To Send (UART1_RTS) Clear To Send (UART1_CTS) Data Terminal Ready (UART1_DTR) Data Set Ready (UART1_DSR) Data Carrier Detect (UART1_DCD) Ring Indicator (UART1_RI) Note: Signal names are according to PC view. 2.11.1.

POWER ON Signal (PWR_ON_N) A low level signal has to be provided to switch the AirPrime HL8518, HL8528 and HL8529 modules ON. It is internally connected to the permanent 1.8V supply regulator inside the HL8518, HL8528 and HL8529 via a pull-up resistor. Once VBAT is supplied to the module, this 1.8V supply regulator will be enabled and so the PWR_ON_N signal is by default at high level. The PWR_ON_N signal’s characteristics are listed in the table below. Table 22. PWR_ON_N Electrical Characteristics Parameter Min Input Voltage-Low (V) Typical Max 0.51 Input Voltage-High (V) 1.33 2.2 Power-up period (ms) from PWR_ON_N falling edge 2000 PWR_ON_N assertion time (ms) 25 Note: As PWR_ON_N is internally pulled up with 200kΩ, a simple open collector or open drain transistor must be used for ignition. The software starts operating when the module is ON, but “AT Command Ready” will depend on whether UART or USB is used. Figure 10. PWR_ON_N Assertion Time VGPIO is an output from the module that can be used to check if the module is active. When VGPIO = 0V, the module is OFF. When VGPIO = 1.8V, the module is ON (it can be in idle, communication or sleep mode) Note: PWR_ON_N cannot be used to power the module off. To power the module off, use AT command AT+CPOF. 2.13. Reset Signal (RESET_IN_N) To reset the module, a low level pulse must be sent on the RESET_IN_N pin for 10ms. This action will immediately restart the AirPrime HL8518, HL8528 and HL8529 modules with the PWR_ON_N signal at low level. (If the PWR_ON_N signal is at high level, the module will be powered off.) As RESET_IN_N is internally pulled up, a simple open collector or open drain transistor can be used to control it. The RESET_IN_N signal will reset the registers of the CPU and reset the RAM memory as well, for the next power on. 4117047 Rev 2.2 December 18, 2015 30 Product Technical Specification Note: Detailed Interface Specifications As RESET_IN_N is referenced to the VGPIO domain (internally to the module), it is impossible to reset before the module starts or to try to use RESET_IN_N as a way to start the module. Another more costly solution would be to use MOS transistor to switch the power supply off and restart the power up procedure using the PWR_ON_N input line. Table 23.

Design Guidelines 3.1. Power-Up Sequence Apply a LOW level logic to the PWR_ON_N pin (pin 59); within 25ms, VGPIO will appear to be at 1.8V. Either a USB or UART1 interface could be used to send AT commands. Note that for USB connections, the time when AT commands can be sent will depend on the initialization time used for the USB connection with the USB host. Figure 11. Note: PWR_ON_N Sequence with VGPIO Information As PWR_ON_N is internally pulled up with 200kΩ, a simple open collector or open drain transistor must be used for ignition. The PWR_ON_N pin has the minimum assertion time requirement of 25ms, with LOW active. Once the valid power on trigger is detected, the PWR_ON_N pin status can be left open. VBATT has to ramp up within 32 ms to reach the value of 3.2V; otherwise, the module may not power up. Figure 12. 3.2. PWR_ON_N Sequence with Trampup Module Switch-Off AT command AT+CPOF enables the user to properly switch the AirPrime HL8518, HL8528 and HL8529 modules off. The PWR_ON signal must be set to high (inactive) before the AT+CPOF command is sent. Note: If the PWR_ON signal is active (low level) when the AT+CPOF command is sent, the module will not power off. If required, the module can be switched off by controlling the power supply. This can be used, for example, when the system freezes and no reset line is connected to the AirPrime HL8518, HL8528 and HL8529 modules. In this case, the only way to get control over the module back is to switch off the power line. 4117047 Rev 2.2 December 18, 2015 32 Product Technical Specification Figure 13. Design Guidelines Power OFF Sequence for PWR_ON_N, VGPIO Note: PWR_ON_N is internally pulled up by 200kΩ to 1.8V. Caution: Ensure that no external pull-ups are applied on IO pins while the module is OFF. 3.3. Emergency Power OFF If required, the module can be switched off by controlling the RESET_IN_N pin (pin 11). This must only be used in emergency situations if the system freezes (not responding to AT commands). To perform an emergency power off, a low level pulse must be sent on the RESET_IN_N pin for 10ms while the PWR_ON signal is inactive (high level). This action will immediately shut the HL8518, HL8528 and HL8529 modules down and the registers of the CPU and RAM memory will be reset for the next power on. 3.4. Sleep Mode Management 3.4.1. Using UART AT command AT+KSLEEP enables sleep mode configuration. AT+KSLEEP=0: The module is active when DTR signal is active (low electrical level). When DTR is deactivated (high electrical level), the module will enter sleep mode after a while. On DTR activation (low electrical level), the module wakes up. AT+KSLEEP=1: The module determines when it enters sleep mode (when no more tasks are running). “0x00” character on the serial link wakes the module up. AT+KSLEEP=2: The module never enters sleep mode. 3.4.2. Using USB Use AT+KSLEEP=1 to allow the module to automatically enter sleep mode while the USB interface is in use. 4117047 Rev 2.2 December 18, 2015 33 Product Technical Specification 3.5. Design Guidelines Power Supply Design The AirPrime HL8518, HL8528 and HL8529 modules should not be supplied with voltage over 4.5V even temporarily or however briefly. If the system’s main board power supply unit is unstable or if the system’s main board is supplied with over 4.5V, even in the case of transient voltage presence on the circuit, the module’s power amplifier may be severely damaged. To avoid such issues, add a voltage limiter to the module’s power supply lines so that VBATT and VBATT_PA signal pads will never receive a voltage surge over 4.5V. The voltage limiter can be as simple as a Zener diode with decoupling capacitors as shown in the diagram below. Figure 14. 3.6. Voltage Limiter Example ESD Guidelines for SIM Card Decoupling capacitors must be added as close as possible to the SIM card connectors on UIM1_CLK, UIM1_RST, UIM1_VCC and UIM1_DATA signals to avoid EMC issues and to pass the SIM card type approval tests, according to the drawings below. A typical schematic for hardware SIM detection is provided below. Figure 15. 4117047 EMC and ESD Components Close to the SIM Rev 2.2 December 18, 2015 34 Product Technical Specification 3.7.
