Low frequency I/O is signals with a frequency up to 10 kHz

Note: An internal 4.7μF bulk capacitor has been included on the module. For those application that with heavy GPIO usage and/or current draw, it is good design practice to add additional bulk capacitance as required for your application.

General Purpose I/O:

Each GPIO can be accessed individually with the following user configurable features:

• Input/output direction
• Output drive strength
• Internal pull-up and pull-down resistors
• Wake-up from high or low level triggers on all pins
• Trigger interrupt on all pins
• All pins can be used by the PPI task/event system; the maximum number of pins that can be interfaced through the PPI at the same time is limited by the number of GPIOTE channels
• All pins can be individually configured to carry serial interface or quadrature demodulator signals

Hardware RESET:
There is on-chip power-on reset circuitry, But can still be used in external reset mode, in this case, GPIO pin P0.18 as an external hardware reset pin. In order to utilize P0.18 as a hardware reset, the UICR registers PSELRESET[0] and PSELRESET[1] must be set alike, to the value of 0x7FFFFF12. When P0.18 is programmed as RESET, the internal pull-up is automatically enabled.

HW debug and flash programming of Module :
The Module support the two pin Serial Wire Debug (SWD) interface and offers flexible and powerful mechanism for non-intrusive debugging of program code. Breakpoints, single stepping, and instruction trace capture of code execution flow are part of this support.

This is the hardware debug and flash programming of module, J-Link Lite support, please refer www.segger.com.

Power and Configuration:
The module has two internal regulator stages. REG1 regulator stage has the regulator type options of Low-dropout regulator (LDO) and Buck regulator (DC/DC). REG0 regulator stage has only the option of Low-dropout regulator (LDO). The first regulator, REG0, is fed by the VDDH pin and can accept a source voltage of 2.5 V to 5.5 V. The output of REG0 is connected to the VDD pin and the input of the second regulator stage REG1. REG1 supplies power to the module core and can accept an input source voltage of 1.7V to 3.6V. Depending on how the VDD and VDDH pins are connected, the module will operate in one of two modes: Normal/Low Voltage (LV) or High Voltage (HV). The voltage present on the VDD pin is always the GPIO high logic level voltage, regardless of power mode.

To enter LV Mode, the same source voltage is applied to both the VDD and VDDH pins causing REG0 to automatically shut down leaving only the REG1 stage active. To enter HV, the source voltage is only applied to VDDH causing the VDD pin to become an output source supplied by REG0.

Mode| Pin of

Module

| Name| Power Connection
---|---|---|---
Normal/Low Voltage

(LV)

| Pin 34| VDD| 1.7V to 3.6V source in
Pin 46| VDDH| Same source as VDD
High Voltage (HV)| Pin 34| VDD| 1.8V to 3.3V supply out
Pin 46| VDDH| 2.5V to 5.5V source in

Important: In both LV and HV modes, the GPIO logic level voltage is determined by the VDD pin. In HV mode, all external devices that are connected to the Module’s GPIO must either be powered by the module (from VDD) or use level translation.

REG0 can supply a maximum current of 25mA for the module and external circuits in System On Mode and 1 mA in System Off Mode. External circuits powered from VDD in HV mode should be limited to no more than 5 mA to ensure stability at all radio transmit power levels.
USB Power: The USB interface on the Module can be used when the module is in either Normal /Low Voltage (LV) or High Voltage (HV) mode. The Module USB PHY is powered by a dedicated, internal LDO regulator that is fed by the VBUS pin (Pin43). This means that applying power to only the VBUS pin will not power the rest of the module. In order for the USB PHY to operate, VBUS must be externally powered.

In this section there are 5 reference circuits to show how to design an application circuit with this module.

Some general guidance is summarized here:

• Main supply voltage is connected to VDD/VDDH. The system will enter one of two supply voltage modes, normal or high voltage mode, depending on how the supply voltage is connected to these pins. Normal voltage mode is entered when the supply voltage is connected to both the VDD and VDDH pins (so that VDD equals VDDH).High voltage mode is entered when the supply voltage is only connected to the VDDH pin and the VDD pin is not connected to any voltage supply.
• By default, the LDO regulators in the chip are enabled and the DC/DC regulator of REG1 stage is disabled. Register DCDCEN is used to enable the DC/DC regulator for REG1 stage. External LC filters has been connected in the Module for DC/DC regulators being used.
• The GPIO high reference voltage always equals the level on the VDD pin. In normal voltage mode, the GPIO high level equals the voltage supplied to the VDD pin, and in high voltage mode it equals the level specified in the register REGOUT0 UICR registers.
• When the power is supplied to VDDH, the output from the VDD pin could be used to supply external circuitry. The feature must be configured in the EXTSUPLLY and REGOUT0 UICR registers. In the reference circuitry, External supply is annotated with the VEXT net name.
• When using the USB peripheral, a 5V USB supply needs to be provided on the VBUS pin.

Recommended RF Layout & Ground Plane:
The module integrated antenna requires a suitable ground plane to radiate effectively. The area under and extending out from the antenna portion of the module should be kept clear of copper and other metal. The module should be placed at the edge of the PCB with the antenna edge facing out. Reducing the ground plane will reduce the effective radiated power. Please add as more as possible via holes on the mother board near the GND pin of module, this will be good for the RF performance of system board.

Notes and Cautions:

Design Notes

1. It is critical to following the recommendations of this document to ensure the module meets the specifications.
2. Power supply must be free of AC ripple voltage. If such noise is present, it is critical to provide proper filtering and decoupling.
3. The module should not be stressed mechanically after installation.
4. Exposing the module to significant temperatures will result in degradation and decreased lifetime.
5. Keep module away from other high frequency devices which may interfere with operation such as other transmitters and devices generating high frequencies.
6. Avoid static electricity, ESD and high voltage as these may damage the module.

Handling and Storage

1. Keep module away from other high frequency devices which may interfere with operation such as other transmitters and devices generating high frequencies.
2. Do not expose the module to the following conditions: Corrosive gasses such as Cl2, H2S, NH3, SO2, or NOX Extreme humidity or salty air Prolonged exposure to direct Sunlight Temperatures beyond those specified for storage.
3. Do not apply mechanical stress.
4. Do not drop or shock the module.
5. Avoid static electricity, ESD and high voltage as these may damage the module.

Moisture Sensitivity
All plastic packages absorb moisture. During typical solder reflow operations when SMDs are mounted onto a PCB, the entire PCB and device population are exposed to a rapid change in ambient temperature. Any absorbed moisture is quickly turned into superheated steam. This sudden change in vapor pressure can cause the package to swell. If the pressure exerted exceeds the flexural strength of the plastic mold compound, then it is possible to crack the package. Even if the package does not crack, interfacial delamination can occur.
Since the device package is sensitive to moisture absorption, it is recommended to bake the product before assembly.
