Product Information Data Sheet

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

DESCRIPTION

With a small form factor of 9×11×1.3mm max., the

apm6658/6659 is a full-featured WiFi 802.11b/g/n &

Bluetooth v2.1+EDR dual radio module that

simultaneously provides WiFi and Bluetooth

connections.

By providing flexible host interfaces combined

with support for embedded operating systems, the

apm6658/6659 enables rapid integration of WiFi and

Bluetooth technology into a variety of host devices. The

pre-tested and pre-certified module eliminates the need

to create custom designs, resulting in greatly reduced

development risk, costs, and time-to-market.

y Support for IEEE 802.11e QoS.
y Support for IEEE 802.11i advanced security.
y Support for WAPI security (apm6658 only)

BLUETOOTH FEATURES

y Bluetooth Specification v2.1+EDR compliant (all

mandatory and optional features)

y UART to 4MBaud

APPLICATIONS

y Smartphone / PDA / PDA phone / WiFi phone / DSC

/ DVC with both WiFi and Bluetooth connectivity

GENERAL FEATURES

y Small footprint: 9×11×1.3 mm max
y Support for state-of-the-art WiFi-Bluetooth

co-existence and VoIP optimizations

y Support for single antenna configuration for WiFi and

Bluetooth

y EEPROM and full RF front-end integrated for WiFi

and Bluetooth

y External clock sharing for WiFi and Bluetooth
y Excellent GSM/GPRS/DCS/PCS/WCDMA/GPS

radio coexistence

y Support for drivers on embedded OS
y RoHS compliant

WIFI FEATURES

y IEEE 802.11b/g/n compliant

APPEARANCE

y Host interface: SDIO 1-bit, SDIO 4-bit, SDIO SPI
