PRELIMINARY

Wireless LAN Integrated Medium Access

Controller with Baseband Processor

Features

• Firmware implements the full IEEE 802.11b/g Wireless

LAN MAC protocols

The Intersil ISL3880 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 GTi™ radio chipset. The

ISL3880 directly interfaces with the Intersil’s ISL3680 Direct

Conversion Transceiver with AGC and synthesizer. Adding

Intersil’s ISL3090 10GHz VCO and Intersil’s ISL3980 Power

Amp completes an end-to-end WLAN Chipset solution for the

2.4GHz 802.11b/g standards. The 802.11Protocol is

implemented in firmware to provide for 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.

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.

• Firmware controlled antenna diversity

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

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

DBPSK, DQPSK, CCK

• Convolutional coding and interleaving on all OFDM rates

• Targeted for OFDM Multipath Delay Spreads from > 800ns

for 6 Mbps to > 100ns for 54Mbps

Orthogonal Frequency Division Multiplexing (OFDM)

modulated with BPSK, QPSK, 16 QAM, or 64 QAM and a

variety of convolutional coding rates provides 8 selectable

data rates. 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.

• Targeted for CCK Multipath Delay Spreads > 90ns at

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

2Mbps

• Direct interface with the ISL3680 Direct Conversion

Transceiver

Applications

Built-in flexibility allows the ISL3880 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.

• High Data Rate Wireless LAN Systems Targeting the IEEE

802.11b/g Standards.

• Cardbus32 Wireless LAN Adapters

• Mini-PCI Wireless LAN Cards

• 3V PCI Wireless LAN Adapters

Ordering Information

The ISL3880 is housed in a thin plastic BGA package

suitable for CardBus or Mini-PCI circuit card applications.
