Features

• USB host interface supports USB V1.1 at 12Mbps.

The Intersil ISL3871 Wireless LAN

Integrated Medium Access Controller

with Integrated Baseband Processor

• New Start up modes allow the PCMCIA card information

structure to be initialized from a serial EEPROM. This

allows firmware to be downloaded from the host,

eliminating the parallel flash memory device

is part of the PRISM® 2.4GHz radio chipset. The ISL3871

directly interfaces with the Intersil’s Zero-IF

QMODEM(ISL3684). Adding Intersil’s Power Amp (ISL3984)

offers the designer a complete end-to-end WLAN chipset

solution. Protocol and PHY support are implemented in

firmware, thus supporting customization of the WLAN

solution.

• Firmware can be loaded from serial flash memory

• Zero glue connection to 16-bit wide SRAM devices

• Low-frequency crystal oscillator to maintain time and allow

baseband clock source to power off during sleep mode

• Improved performance of internal WEP engine

• Improvements to debug mode support tracing execution

from on chip memory

Firmware implements the full IEEE 802.11 Wireless LAN

MAC protocol. It supports BSS and IBSS operation under

DCF, and operation under the optional point coordination

function (PCF). Low level protocol functions such as

RTS/CTS generation and acknowledgment, fragmentation

and de-fragmentation, and automatic beacon monitoring are

handed without host intervention. Active scanning is

performed autonomously once initiated by host command.

Host interface command and status handshakes allow

concurrent operations from multi-threaded I/O drivers.

Additional firmware functions specific to access point

applications are also available.

• Programmable MBUS cycle extension allows accessing of

slow memory devices without slowing the clock

• Complete DSSS baseband processor

• RAKE receiver with decision feedback equalizer

• Processing gain. . . . . . . . . . . . . . . . . . . . . FCC compliant

• Programmable data rate . . . . . . . . . 1, 2, 5.5, and 11Mbps

• Available in two packages:

- Ultra small BGA package. . . . . . . . . . . . . . . 14 x 14mm

- Large LQFP flat pack for easy board layout

• Modulation methods . . . . . . . .DBPSK, DQPSK, and CCK

• Supports full or half duplex operations

• On-chip A/D and D/A converters for I/Q data, AGC, and

adaptive power control

The ISL3871 has on-board A/D’s and D/A for analog I and Q

inputs and outputs, for which the ISL3684 Zero-IF QMODEM

is recommended. Differential phase shift keying modulation

schemes DBPSK and DQPSK, with data scrambling

capability, are available along with Complementary Code

Keying to provide a variety of data rates. Both Receive and

Transmit AGC functions with 7-bit AGC control obtain

maximum performance in the analog portions of the

transceiver.

• Targeted for multipath delay spreads 100ns at 11Mbps,

250ns at 5.5Mbps

• Supports short preamble and antenna diversity

Applications

• PC Card Wireless LAN Adapters

• USB Wireless LAN Adapters

• PCN / Wireless PBX / Wireless Local Loop

Built-in flexibility allows the ISL3871 to be configured

through a general purpose control bus, for a range of

applications. The ISL3871 is housed in either a thin plastic

BGA package or a TQFP flat pack suitable for PCMCIA

board applications.

• High Data Rate Wireless LAN Systems Targeting IEEE

802.11b Standard

• Wireless LAN Access Points and Bridge Products

• Spread Spectrum WLAN RF Modems

• TDMA or CSMA Packet Protocol Radios

• ISA, ISA PnP WLAN Cards

The ISL3871 is designed to provide maximum performance

with minimum power consumption. External pin layout is

organized to provide optimal PC board layout to all user

interfaces including PCMCIA and USB.
