DESCRIPTION
The module is a high performance 2.4GHz
IEEE 802.11 b/g/n, Bluetooth 2.1+EDR, and
Bluetooth Low Energy (BLE) 4.0 radio in a cost
effective, pre-certified footprint.
The module realizes the necessary PHY/MAC
layers to support WLAN applications in
conjunction with a host processor over a SDIO
interface.
The module also provides a Bluetooth platform
through the HCI transport layer. Both WLAN
and Bluetooth share the same antenna port.

ELECTRICAL SPECIFICATIONS
The majority of these characteristics are based on controlling and conditioning the tests using the
control software application. Other control conditions may require these values to be re-characterized
by the customer.

1. Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device and are not
covered by the warranty. These are stress ratings only and functional operation of the device at these or any other
conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolutemaximum-rated conditions for extended periods may affect device reliability.
2. All parameters are measured as follows unless stated otherwise: VDD_IN=1.8V, VDDIO_1.8V=1.8V,
VDD_LDO_CLASS1P5=3.6V
3. Analog pins: XTALP, XTALM, RFIOBT, DRPWRXBM, DRPWRXBP, DRPWTXB, and also FMRFINP, FMRFINM,
FMRFINM, FMAUDLIN, FMAUDRIN, FMAUDLOUT, FMAUDROUT
4. The following signals are from the VBAT group, PMS_VBAT and VDD_LDO_CLASS1P5 (if BT class 1.5 direct VBAT is
used).
5. Maximum allowed depends on accumulated time at that voltage; 4.8V for 7 years lifetime, 5.5V for 6 hours cumulative.
6. The device can be reliably operated for 5,000 active-WLAN cumulative hours at T
