AR6102 ROCm
TM
MAC/BB/Radio for 2.4 GHz Embedded WLAN
Applications
General Description
This document describes the AR6102, Rev. 2.1.
The Atheros AR6102 is a member of the WLAN
ROCm family of chips. The compact size and low
power consumption of this design make it an
ideal vehicle for adding WLAN to hand-held and
other battery-powered consumer electronic
devices. The IEEE 802.11g (2.4 GHz) standard is
supported by this chipset.
The AR6102 family includes a highly integrated,
RF front-end (Power Amplifier, Low-Noise
Amplifier and RF switch) and high-frequency
reference clock, enabling low-cost designs with
minimal external components. Advanced
architecture and protocol techniques save power
during sleep, stand-by and active states.
The AR6102 family supports 2, 3 and 4 wire
Bluetooth coexistence protocols with advanced
algorithms for predicting channel usage by the
co-located Bluetooth transceiver. A 26MHz
reference clock output is also available,
eliminating the need for a dedicated BT clock.
The AR6102 provides multiple peripheral
interfaces including UART.
AR6102 Features
■ IEEE 802.11b/g compliant
■ Data rates of 1–54 Mbps for 802.11g
■ Advanced power management to minimize
standby, sleep and active power
■ Security support for WPS, WPA2, WPA,
WAPI and protected management frames
■ Support for 2.4 GHz operation in all available
bands in all regulatory domains
■ Full 802.11e QoS support including WMM
and U-APSD
■ Support for fast Tx and Rx antenna diversity
allowing optimal antenna selection on a per-
packet basis
■ Supports both SDIO 1.1 and GSPI host
interfaces.
■ Standard 2, 3 and 4 wire Bluetooth
coexistence handshake support
■ 16550-compliant UART
■ Wake-on-Wireless (WoW) maximizes host
sleep duration
■ 7.4 x 8 mm LGA package
■ Pre-certified to meet FCC, ETSI, and TELEC
standards
■ Integrated PA, LNA, RF switch and High
Freq Reference Clock, minimizing external
component count
■ Integrated RF shielding
■ Suports cellular co-existence with an external
band-pass filter
