apm6658/6659 WiFi 802.11 b/g/n & BT2.1+EDR Dual Radio Module

Product Information Data Sheet

The WiFi firmware does not incorporate any support for writing to the EEPROM during normal operation. This

significantly reduces the risk of spurious writes corrupting the contents of the EEPROM, and means it is not possible

to repair any damage that may occur. Hence, it is suggested that keep the pin, WL_WP, permanently pulled high to

minimize the risk of data corruption.

1-6 External Voltage Source

The external supply rails to apm6658/6659 should have less than 10mV rms noise levels between 0 to 10 MHz.

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

1-6-2 Bluetooth Reset

The BT_RESETB pin is an active low reset and is internally filtered using the internal low frequency clock

oscillator. 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.

4 Assembly Guideline

4-1 Recommended Mounting Pad Design (Top View)

The following figure illustrates the recommended mounting pad design for apm6658/6659.

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

Product Information Data Sheet

‧ The solder paste pattern for the internal Tab pads could be split into 4 smaller segments for the 2 large pads, and

2 smaller segments for the smaller pads, this should have the effect of preventing the paste from pooling into one area,

and hence minimize the likelihood of the pads being held away from each other. 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.

4-3 Baking condition recommendation before IR reflow

Baking condition for apm6658/6659 module:

I: 125°C/4 hrs baking is necessary for apm6658/6659 module before SMT process. After baking treatment the

modules can be stored in the environment under 30°C and 60% RH for 48 hrs. If the storage time is over 48 hrs,

the modules need to be re-baked using the same condition again.

II: In the event that the sealed bag is damaged on receipt of the modules, the baking condition should be changed to

125°C/8 hrs.
