Features

• Firmware implements the full IEEE 802.11 Wireless LAN

MAC protocol

The Intersil ISL3872 Wireless LAN

Integrated Medium Access Controller

with Integrated Baseband Processor

• Improved Performance of Internal WEP Engine

• Improvements to Debug Mode Support Tracing Execution

From on Chip Memory.

is part of the PRISM® III, 2.4GHz

radio chipset. The ISL3872 directly interfaces with the

Intersil’s RF Front End (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, allowing customization of the WLAN

solution.

• New Start Up Modes Allow the PCI and mini PCI

Configuration Registers to be Initialized From a Serial

EEPROM. This Allows Firmware to be Downloaded from

the Host, Eliminating the Parallel Flash Memory Device

• Firmware Can be Loaded from Serial Flash Memory

• Zero Glue Connection to 16-Bit Wide SRAM Devices

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

handled 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.

• Low Frequency Crystal Oscillator to Maintain Time and

Allow Baseband Clock Source to Power off During Sleep

Mode

• 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

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

• Supports full or half duplex operations

The ISL3872 has on-board A/D and D/A converters 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.

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

adaptive power control

• Targeted for Multipath Delay Spreads 100ns at 11Mbps,

250ns at 5.5Mbps

Built-in flexibility allows the ISL3872 to be configured

through a general purpose control bus, for a range of

applications.

• Supports Short Preamble and Antenna Diversity

Applications

The ISL3872 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 mini PCI.

• High Data Rate Wireless LAN Systems Targeting IEEE

802.11b Standard

• Mini PCI and 3V PCI Wireless LAN Adapters

• PCN / Wireless PBX / Wireless Local Loop

• Wireless LAN Access Points and Bridge Products

• Spread Spectrum WLAN RF Modems

The ISL3872 is housed in a thin plastic BGA package

suitable for mini PCI board applications.

Ordering Information

• TDMA or CSMA Packet Protocol Radios
