Single tone frequencies are also to be avoided. Transient response of external regulators used should be <= 5us for WiFi and <= 20us for Bluetooth, respectively. Supply voltage range 1.8V 1.8V+/- 5% (ripple Vpp<10mV rms) 3.3V 3.3V +/-5% (ripple Vpp<10mV rms) 1-6-1 WiFi Reset WL_RESETn is an active low reset input that is internally filtered using the internal low frequency clock oscillator to avoid spurious resets. A reset occurs after the signal has been asserted for between 250 and 375us. This pin may be tied to WL_VDD_PADS_0_7 if unused; otherwise it should be asserted for at least 1ms to force a reset. The power supply supervisor monitors WL_VDD_CORE (internal module voltage) to trigger a power-on-reset. This occurs when the supply falls below 1.05V (typical) in normal operation or 0.825V (typical) in deep sleep, and ends when the supply exceeds 1.10V (typical). Glitches of up to 30mV and 2.5us duration, which could be caused by large load steps, will not trigger a reset. Each of the internal processors has its own independent watchdog timer to detect and recover from erroneous software operation. These are typically configured with a timeout of 1.5s, but this may be increased up to a maximum of 64s for reduced power consumption. The watchdogs are enabled at power-on and continue operating while WiFi is in deep sleep. During all forms of reset most digital I/O pins (including both bidirectional pins and dedicated inputs or outputs) default to high impedance with weak internal pull-downs. The only exceptions are WL_RESETn and WL_SPI_CS which both have pull-ups, and the SDIO/CSPI bus which is on an independent reset domain. The SDIO/CSPI host interface is only fully reset by the WL_RESETn pin or the power supply supervisor; other forms of reset leave the host interface initialized but simply clear the I/O Enable bit for function 1. Following a reset, WiFi automatically generates safe clocks for internal use. If an external reference clock is connected to WL_CLK then this is assumed to be at the maximum supported frequency, otherwise the PLL free runs at

A reset is performed between 1.5 and 4.0ms following BT_RESETB being active. It is recommended that BT_RESET be applied for a period greater than 5ms. The power on reset occurs when the BT_VDD_CORE supply falls below 1.24V and is released when BT_VDD_CORE rises above typically 1.31V. At reset the digital I/O pins are set to input for bi-directional pins and outputs are tri-state. Following a reset, BT assumes the maximum BT_CLK frequency, which ensures that the internal clocks run at a safe (low) frequency until BT is configured for the actual BT_CLK frequency. If no clock is present at BT_CLK, the oscillator in BT free runs, again at a safe frequency.

TOP VIEW (mm) 4-2 Recommendation for Stencil Aperture in SMT Process Please follow general QFN stencil design guideline. Some rules of thumb are highlighted below. ‧ The LGA pads should NOT be flooded over with copper, they should be connected into the plane with a track width of approx 50% of the pad width, this will mean more heat will be available at the joint. Track lengths should obviously be minimized, we would generally use about 0.3mm on external layers.

We use a rule of thumb of 50% solder paste area in relation to Tab copper area (this only applies to tab pads under the device – not the signal pads). ‧ The thickness of the solder paste stencil has implications on solder joint quality as well, we do not have the knowledge on what stencil should be specified. ‧ Ensure they are using a good appropriate flux, and the correct reflow profile for unleaded (basically +20C above leaded) which is also uniform in nature. Violating the basic rules might cause problems. For example, if the stencil apertures of the internal ground planes are improperly big, they would hold more solders in SMT process and may cause the module peripheral pads un-contacted to the main board. To improve this situation, apmcomm suggests the stencil opening shown as follows. Stencil Aperture (Top View)

Federal Communication Commission Interference Statement This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This module can be used with Getac PDA: PS336 or similar platform with similar dimension, antenna location and RF characteristic. This device is intended only for OEM integrators under the following conditions: 1) The antenna must be installed at same location as tested in the certification filing. 2) The transmitter module may not be co-located with any other transmitter or antenna. 3) For portable usage condition, this module has been SAR evaluated in Getac PDA: PS336 host with compliance result and can be used with this specific hast as described in the certification filing. Other host or platform needs separate approval. As long as 3 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling The final end product must be labeled in a visible area with the following: “Contains FCC ID: QYLAPM6658”.
