Absolute Maximum Ratings (1) 1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2) 5.5V up to 10s cumulative in 7 years, 5V cumulative to 250s, 4.8V cumulative to 2.33 years - all includes charging dips and peaks. 3) Operating free-air temperature range. The device can be reliably operated for 7 years at ambient of 85°C, assuming 25% active mode and 75% sleep mode (15,400 cumulative active power-on hours). 4) Electrostatic discharge (ESD) to measure device sensitivity/immunity to damage caused by electrostatic discharges into device. 5) Level listed is the passing level per ANSI/ESDA/JEDEC JS-001. JEDEC document JEP155 states that 500V HBM allows safe manufacturing with a standard ESD control process, and manufacturing with less than 500V HBM is possible if necessary precautions are taken. Pins listed as 1000V may actually have higher performance. 6) Level listed is the passing level per EIA-JEDEC JESD22-C101E. JEDEC document JEP157 states that 250 V CDM allows safe manufacturing with a standard ESD control process, and manufacturing with less than 250V CDM is possible if necessary precautions are taken.

CLOCK AND POWER MANAGEMENT The slow clock is a free-running, 32.768 kHz clock supplied from an external clock source. The clock is connected to the RTC_CLK pin and is a digital square-wave signal in the range of 0 to 1.8V nominal 6.1. Reset-Power-Up System After VBAT and VIO are fed to the device and while BT_EN and WL_EN are deasserted (low), the device is in SHUTDOWN state, during which functional blocks, internal DC-DCs, and LDOs are disabled. The power supplied to the functional blocks is cut off. When one of the signals (BT_EN or WL_EN) are asserted (high), a power-on reset (POR) is performed. Stable slow clock, VIO, and VBAT are prerequisites for a successful POR. 6.2. WLAN Power-Up Sequence Figure 6-1 shows the WLAN power-up sequence. Figure 6-1. WLAN Power-Up Sequence

Design Note on Debug Port  Pin# 11, 12 serve as WLAN and BT debug port, respectively. So test points for these two signals should be reserved for debugging purpose.  Pin# 14 (SDIO WAKE#) needs to be pulled high via 10Kohm and use Pin# 11, 12 as hardware interface to communicate with system platform and TI RTTT test utility for WLAN RF performance test, debug and manufacturing application. 8.2. Module Layout Recommendations Follow these module layout recommendations:  Digital Signals Layout  SDIO signals traces (CMD, D0, D1, D2 and D3) should be routed in parallel to each other and as short as possible. (Less than 12cm) Besides, every trace length must be the same as the others.  Enough space above 1.5 time trace width or ground shielding between trace and trace will be benefit to make sure signal quality, especially for SDIO_CLK trace. Remember to keep them away from the other digital or analog signal traces. Adding ground shielding around these bus is recommended.  Route trace of SDIO_CLK at Top layer without vias.  SDIO Clock, Audio Clock (PCM_AUD_CLK), these digital clock signals are a source of noise. Keep the traces of these signals as short as possible. Whenever possible, maintain a clearance around them.  BT_AUD signals should be rounted in the same group and it’s better to rout them at the same layer or confirm them referring to the same reference plane.  Power Trace  Power trace for VBAT should be 20mil wide. 1.8V trace should be 15mil wide, at least.  Isolate different power traces with Ground plane  Ground  Having a complete Ground and more GND vias under module in layer1 for system stable and thermal dissipation.
