AR7100: A Scalable, High Performance And Cost-Effective
Network Processor Family
General Description
Features
The Atheros AR7100 is a scalable, high
performance and cost effective network
processor family that allows efficient design of
solutions addressing triple play services such
as voice, video and data for home and
enterprise access point, router and gateway
applications. It includes a 32-bit MIPS
processor, PCI host interface, two 802.3
Ethernet MACs with GMII/RGMII/RMII/MII
interface, two USB 2.0 MAC/PHYs, a PCM
interface for glueless SLIC support, external
memory interface for serial Flash and DDR-
SDRAM, a high-speed UART, I2S interface, and
GPIOs that can be used for LED controls.
The AR7100 network processor when paired
with the AR9100 chipset family (AR9160
MAC/baseband processor and AR9106/
AR9104/AR9103/AR9102/AR9101 radios)
provides the best in class WLAN solution
capable of supporting 802.11a/b/g/n
standards.
■ Integrated MIPS 24K-family processor
■ 300–680 MHz processor frequency:
– AR7130, 300 MHz, Fast Ethernet version
– AR7141, 400 MHz, supports Fast
Ethernet and GB Ethernet
– AR7161, 680 MHz, supports Fast
Ethernet and GB Ethernet
■ High Performance DDR memory controller
(16- or 32-bit)
■ Dual IEEE 802.3 Ethernet MAC supporting
10/100/1000 Mbps, full and half duplex
and GMII/RGMII/RMII/MII interfaces
■ Two-port USB 2.0 Host Controllers with
built-in MAC/PHY
■ UART for console support
■ 32-bit, 33/66 MHz PCI 2.3 host interface
supporting up to three client devices
■ IEEE 1149.1 standard test access port and
boundary scan architecture supported
■ JTAG based debugging of the processor
core supported
■ 13 mm x 13 mm 384 TFBGA lead-free
package
■ Along with the Atheros AR9100 (MAC/BB
and radio chips) family—Completes an all-
CMOS solution for 802.11a/b/g/n WLANs,
supporting extended range for worldwide
operations
