Data Sheet

April 2003

FN8004.1

Wireless LAN Integrated Medium Access

Controller with Baseband Processor

Features

• Firmware implements the full IEEE 802.11a Wireless LAN

MAC protocol

The Intersil ISL3877 Wireless LAN

Integrated Media Access Controller

• Internal WEP Engine allows 64 or 128 bit Encryption

with Baseband Processor is part of

the PRISM® 5, 5GHz radio chipset.

• Start Up Modes Allow the PCI Configuration Registers or

the Card Bus Card Information Structure to be Initialized

from a small external Serial EEPROM. This allows

Firmware to be Downloaded from the Host

The ISL3877 directly interfaces with the Intersil’s ISL3787

1.2GHz IF converter with AGC and synthesizer. Adding

Intersil’s ISL3687 5GHz RF/IF converter with integrated

synthesizer and a Power Amp completes an end-to-end WLAN

Chipset solution for the 802.11a 5GHz standard. Protocol and

PHY support are implemented in firmware thus, supporting

custom WLAN solutions.

• On chip SRAM Memory

• Low Frequency Crystal Oscillator to Maintain Time and

Allow High Frequency Clock Source to Power off During

Sleep Mode

• Complete OFDM Baseband Processor and 802.11a MAC

• Firmware controlled antenna diversity

Firmware implements the full IEEE 802.11a 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.

• Data Rates . . . . . . . . 6, 9, 12, 18, 24, 36, 48, and 54Mbps

• RF Modulation Method. . . . . . . . . . . . . . . . . . . . . . .OFDM

• Baseband modulations. . BPSK, QPSK, 16 QAM, 64 QAM

• Convolutional coding and interleaving on all rates

• Targeted for Multipath Delay Spreads 100nS at 6Mbps

and 100ns at 54Mbps

• Direct interface with the ISL3787 IF Converter

• Balanced differential interconnects to TX and RX

Orthogonal Frequency Division Multiplex (OFDM) combined

with BPSK through 64 QAM modulation of the individual

carriers and a variety of convolutional coding rates provides

8 selectable data rates.

Applications

• High Data Rate Wireless LAN Systems Targeting the

IEEE 802.11a Standard

Built-in flexibility allows the ISL3877 to be configured for a

range of applications. The MAC is based on the ARM 946E

processor core that offers a wide variety of code

development support tools.

• Cardbus32 Wireless LAN Adapters

• Mini-PCI Wireless LAN Cards

• 3V PCI Wireless LAN Adapters

The ISL3877 is housed in a thin plastic BGA package

suitable for CardBus or Mini-PCI circuit card applications.
