SIM card slot are described as follows: When the SIM card is detached, it connects the short circuit between CD and SW pins, and drives the SIM_DETECT pin low. When the SIM card is inserted, it connects an open circuit between CD and SW pins, and drives the SIM_DETECT pin high. 3.5.2.2 N.O. SIM Card Slot The reference circuit design for N.O. (Normally Open) SIM card slot is shown in Figure 3-12: Reproduction forbidden without Fibocom Wireless Inc. written authorization - All Rights Reserved. L830-EB-11 Hardware User Manual Page 23 of 39 Figure 3-12 Reference Circuit for N.O. SIM Card Slot The principles of the N.O. SIM card slot are described as follows: When the SIM card is detached, it connects an open circuit between CD and SW pins, and drives the SIM_DETECT pin low. When the SIM card is inserted, it connects the short circuit between CD and SW pins, and drives the SIM_DETECT pin high. 3.5.3 USIM Hot-Plugging The L830 module supports the SIM card hot-plugging function, which determines whether the SIM card is inserted or detached by detecting the SIM_DETECT pin state of the SIM card slot. The SIM card hot-plugging function can be configured by “AT+MSMPD” command, and the description for AT command as shown in the following table: AT Command Hot-plugging Detection Function Description Default value, the SIM card hot-plugging detection function AT+MSMPD=1 Enable is enabled. The module can detect whether the SIM card is inserted or not through the SIM_DETECT pin state. The SIM card hot-plugging detect function is disabled. AT+MSMPD=0 Disable The module reads the SIM card when starting up, and the SIM_DETECT status will not be detected. Reproduction forbidden without Fibocom Wireless Inc. written authorization - All Rights Reserved. L830-EB-11 Hardware User Manual Page 24 of 39 After the SIM card hot-plugging detection function is enabled, the module detects that the SIM card is inserted when the SIM_DETECT pin is high, then executes the initialization program and finish the network registration after reading the SIM card information. When the SIM_DETECT pin is low, the module determines that the SIM card is detached and does not read the SIM card. Note: By default, SIM_DETECT is active-high, which can be switched to active-low by the AT command. Please refer to the AT Commands Manual for the AT command. The system doesn’t need SIM hot-plug function, please left SIM_DTECT floating. 3.5.4 USIM Design The SIM card circuit design shall meet the EMC standards and ESD requirements with the improved capability to resist interference, to ensure that the SIM card can work stably. The following guidelines should be noted in case of design: The SIM card slot placement should near the module as close as possible, and away from the RF antenna, DC/DC power supply, clock signal lines, and other strong interference sources. The SIM card slot with a metal shielding housing can improve the anti-interference ability. The trace length between the SIM card slot and the module should not exceed 100mm, or it could reduce the signal quality. The UIM_CLK and UIM_DATA signal lines should be isolated by GND to avoid crosstalk interference. If it is difficult for the layout, the whole SIM signal lines should be wrapped with GND as a group at least. The filter capacitors and ESD devices for SIM card signals should be placed near to the SIM card slot, and the ESD devices with 22~33pF capacitance should be used. 3.6 Status Indicator The L830 module provides three signals to indicate the operating status of the module, and the status indicator pins as shown in the following table: Pin Pin Name I/O Reset Value 10 LED1# PD 23 WOWWAN# PU Pin Description System status LED, drain output.

L830-EB-11 Hardware User Manual Page 27 of 39 3.7.2 Body SAR The L830 module supports Body SAR function by detecting the DPR pin. The voltage level of DPR is high by default, and when the SAR sensor detects the closing human body, the DPR signal will be pulled down. As the result, the module then lowers down its emission power to its default threshold value, thus reducing the RF radiation on the human body. The threshold of emission power can be set by the AT Commands. The definition of DPR signal as shown in the following table: DPR signal Function High/Floating The module keeps the default emission power Low Lower the maximum emission power to the threshold value of the module. 3.8 Digital Audio The L830 module supports I2S digital audio interface and it supports the ordinary I2S mode and PCM mode.

It supports 16bit and 32bit mode. 3.8.2 PCM Mode In the case of the Bluetooth (BT) call, the PCM mode is used to transmit digital voice data if the BT chip does not support I2S. For the scenario, the module works as the PCM master, and BT works as the PCM slave mode. The signal connection under the PCM mode is shown in Figure 3-19: Figure 3-19 Signal Connection for PCM Mode Description: The PCM mode interface can be configured as master or slave mode. It supports various audio sampling rates (444.1KHz,32KHz,24KHz,16KHz,8KHz). It supports short frame sync for 16 and 32 bit mode. It supports burst and continuous transmission modes. It supports clock length trigger for frame sync signal and rising/falling edge trigger for data transmission. Note: The PCM mode timing is relative complicated to adjust, and the audio quality will be reduced if it is not fine tuned. In contrast to PCM mode, I2S mode is easier to adjust, hence it is recommended to use I2S mode. 3.9 I2C Interface Description The L830 module supports one I2C interface, which is configured as I2C master by default.
