Pad Definition AirPrime HL6528RDx module pads are divided into 3 functional categories.  Core functions and associated pads cover all the mandatory features for M2M connectivity and will be available by default across all CF 3 family of modules. These Core functions are always available and always at the same physical pad locations. A customer platform using only these functions and associated pads is guaranteed to be forward and/or backward compatible with the next generation of CF3 modules.  Extension functions and associated pads bring additional capabilities to the customer. Whenever an Extension function is available on a module, it is always at the same pad location.  Custom functions and associated pads are specific to a given module, and make an opportunistic use of specific chipset functions and I/Os. Custom features should be used with caution as there is no guarantee that the custom functions available on a given module will be available on other CF3 modules. Other pads marked as “not connected” or “reserved” should not be used. Table 6.

It consists of a flexible 8-wire serial interface that complies with RS-232 interface. The supported baud rates of the UART1 are 1200, 2400, 4800, 9600, 19200, 38400, 57600 and 115200 bit/s, with autobauding and up to 1Mbit/s at maximum baud rate. 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: The capacitive load at UART1_CTS and UART1_RX must be lower than 45pF on the HL6528RD and HL6528RD-G (1.8V configuration). A UART transceiver or uni-directional level shifter is needed for connection to the host when the interface level is not compatible with the HL6528RDx. UART1 pad description is summarized below.

Power On Signal (PWR_ON_N) A low level signal has to be provided to switch the AirPrime HL6528RDx module ON. It is internally connected to the permanent 3.0V supply regulator inside the HL6528RDx via a pull-up resistor. Once VBATT is supplied to the HL6528RDx module, this 3.0V supply regulator will be enabled and so 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 Minimum Typical Maximum Input Voltage-Low (V) 0 - 0.4 Input Voltage-High (V) 2.4 (TBC) - 3.15 Power-up period (ms) from PWR_ON_N falling edge 2000 - - Note: As PWR_ON_N is internally pulled up (typically by 100kΩ), a simple open collector or open drain transistor must be used for ignition. For convenience, PWR_ON_N can be connected to GND to automatically switch the module on when power is supplied. Switch X 1 2 PWR_ON_N 3 GND Figure 8.

PWR_ON_N Connection Example with an Open Collector Transistor 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 = 2.8V or 1.8V the module is ON (it can be in Idle, Communication or Sleep mode) Caution: VGPIO is always on when PWR_ON_N is at low level even during module reset. Note: PWR_ON_N cannot be used to power the module off. The module is powered off with AT command AT*PSCPOF, and the PWR_ON_N signal will be internally pulled up to high level after. 4117701 Rev 3.0 March 03, 2016 32 Product Technical Specification Detailed Interface Specifications 3.11. Reset Signal (RESET_IN_N) To reset the module, the RESET_IN_N pad must be tied low for at least 10ms (with PWR_ON_N at low level). This action will immediately restart the AirPrime HL6528RDx module. It is therefore not necessary to perform a new ignition sequence (PWR_ON_N) afterwards. As RESET_IN_N is internally pulled up (typically by 100kΩ), 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. Note: As RESET_IN_N is referenced to the 1.8V domain (internally pulled up to the module) it is impossible to enable a reset before the module is on or to try to use the RESET_IN_N as a way to power on the module. Caution: The module will be off if PWR_ON_N is high and RESET_IN_N is tied to low. Table 23.

ADC Two Analog to Digital Converter inputs, ADC0 and ADC1, are provided by the AirPrime HL6528RDx module. These converters are 10-bit resolution ADCs ranging from 0 to 2.8 V. Typically, the ADCx input can be used to monitor external temperature. This is very useful for monitoring the application temperature and can be used as an indicator to safely power OFF the application in case of overheating (for Li-Ion batteries). Both ADCs have the characteristics listed in the table below. Table 24.

Analog Audio Interfaces The AirPrime HL6528RDx module supports one differential microphone input and one differential speaker output. It also includes a noise suppression and echo cancellation feature for enhanced voice call quality. 3.14.1. 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 HL6528RDx 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. The gain of the microphone input can be tuned using AT commands. The AirPrime HL6528RDx module microphone pads already include suitable biasing for an electret microphone. The electret microphone can then be connected directly on the inputs for easy connection. AC coupling is also already embedded in the HL6528RDx embedded module.

PCM The Digital Audio Interface (PCM) allows connectivity with standard audio peripherals. It can be used, for example, to connect an external audio codec. The signals used by the Digital Audio Interface are as follows:  PCM_SYNC: The frame synchronization signal delivers an 8kHz frequency pulse that synchronizes the frame “data in” and the frame “data out” (short frame synchronization only).  PCM_CLK: The frame bit clock signal controls data transfer with the audio peripheral. 4117701 Rev 3.0 March 03, 2016 35 Product Technical Specification Detailed Interface Specifications  PCM_OUT: The frame “data out” relies on the selected configuration mode.  PCM_IN: The frame “data in” relies on the selected configuration mode. The PCM interface is a high speed full duplex interface that can be used to send and receive digital audio data to external audio ICs. The digital audio interface also features the following:  PCM master mode  8 bits or 16 bits data word length  MSB or LSB first  Rising or falling sampling clock edge  The programmability of this interface allows addressing a large range of audio peripheral Note: The PCM bit clock rate must be set to 1MHz in order to accommodate the 8kS/s source/sink mechanism on the DSP side, as well as the 125µs frame length. Refer to the following table for the electrical characteristics of the digital audio interface. Table 29.

The main characteristics of the I2C interface are as follows:  Master mode (I2C1_CLK is an output of the AirPrime HL6528RDx module)  I2C clock is set at 400KHz As the HL6528RDx’s I2C interface works in master mode only, devices connected to the I2C bus shall be slave devices, and in order for the HL6528RDx module to communicate with slave devices, the slave device’s 7-bit address should be loaded inside the HL6528RDx module before activating the GPS NMEA output. For more information on managing slave devices, refer to document [2] AirPrime HL6528RDx AT Commands Interface Guide. 3.17.

TX Burst Indicator (2G_TX_ON) The AirPrime HL6528RDx module provides a signal, 2G_TX_ON, for TX burst indication. 2G_TX_ON is a 2.8V signal and its status depends on the module transmitter state. Refer to the following table for the status of the 2G_TX_ON signal depending on the embedded module’s state. Table 37. 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. The blinking frequency is about 217Hz. The output logic high duration, Tduration, depends on the number of TX slots and is computed as follows: T duration = T advance + (0.577ms x number of TX slots) + T delay Table 38.

GNSS Interface The AirPrime HL6528RD-G and HL6528RD-G2.8V modules embed an integrated and high-sensitivity Global Navigation Satellite System (GNSS) solution. Based on SiRFstarV™ from CSR, the AirPrime HL6528RD-G and HL6528RD-G2.8V modules combine GPS and GLONASS reception to improve navigation capabilities and position accuracy in obstructed view environments such as urban canyons. GNSS performances are improved by CW jammer and interference mitigation system and automated hardware blanking capabilities. In addition, it supports Downloaded Extended Ephemeris Assisted-GNSS, for enhanced time to acquire or reacquire a fix. The operation of GNSS is offloaded to a GNSS standalone solution to guarantee the availability of modem resources for best performance. The GNSS implementation supports GPS L1 signal (1575.42 ± 20 MHz) and GLONASS L1 FDMA signals for frequency -7 to 6 (1597.5 – 1605.8 MHz), with 50Ω connection on the RF_GPS pad. 3.21.1.
