Wireles s LAN Integrated Medium Acces s

Controller with Bas eband Proces s or

Features

• Firmware implements the full IEEE 802.11a/b/g/h/i/j

Wireless LAN MAC protocols

The Intersil ISL3886 Wireless LAN

Integrated Media Access Controller

• Internal WEP Engine allows 64 or 128 bit Encryption

• AES Hardware Accelerator

with Baseband Processor is part of

the PRISM Duette™, Dual Band

radio chipset. The ISL3886 directly interfaces with Intersil’s

ISL3692 Dual Band Direct Conversion transceiver. Adding

Intersil’s ISL3092 10GHz VCO and Intersil’s ISL3992 Dual Band

Power Amp completes an end-to-end WLAN Chipset solution

compliant with 802.11a/b/g/h/i/j standards. The 802.11 protocol

is implemented in firmware supporting custom WLAN

solutions.

• 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.

• On-chip SRAM memory

• A low frequency crystal oscillator can maintain time, which

allows the high frequency clock source to be powered off

during sleep mode.

Software 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). 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.

• Firmware controlled antenna diversity

• Data Rates: 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, & 54Mbps

• Modulation . . OFDM with BPSK, QPSK, 16QAM, 64QAM

DBPSK, DQPSK, CCK

• Convolutional coding and interleaving on all OFDM rates

Orthogonal Frequency Division Multiplexing (OFDM) of 52

sub-carriers modulated with BPSK, QPSK, 16QAM or

64QAM and a variety of convolutional coding rates provides

8 selectable data rates at 2.4GHz and 5GHz. Differential

phase shift keying modulation schemes, DBPSK and

DQPSK with data scrambling capability along with

Complementary Code Keying provide an additional 4

selectable data rates at 2.4GHz.

• Targeted for OFDM Multipath Delay Spreads >800ns for

6Mbps, and >100ns for 54Mbps

• Targeted for CCK Multipath Delay Spreads >90ns at

11Mbps, >200ns at 5.5Mbps and >360ns at 1 and 2Mbps

• Direct interface with the ISL3690 Direct Conversion

transceiver

• High Data Rate Wireless LAN Systems targeting the IEEE

802.11a and b/g standards.

Built-in flexibility allows the ISL3886 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 ISL3886 is housed in a thin plastic BGA package

suitable for CardBus or Mini-PCI circuit card applications.
