Section 1 Functional Description

INTRODUCTION

The BCM4318/BCM4318E offer flexible support for a variety of system bus interfaces including PCI, Mini PCI, CardBus, PCMCIA, Compact Flash, and SDIO/SPI. Customer-specified parameters, such as System Vendor ID and Wireless LAN MAC address, are stored in a small external SPROM.

In addition, the BCM4318E chip includes leading-edge Encore DSP technology for improved receive sensitivity, which extends the range and enables whole home coverage. The BCM4318E chip also supports a UART interface for WLAN design support.

The package options are 144 pin and 196 pin, as follows:
• The BCM4318 chip in the 196-pin package adds PCI, CardBus, and BCM2060 IEEE 802.11a radio interfaces, but does not support Encore DSP technology.
• The BCM4318E chip in the 196-pin package adds PCI, CardBus, and BCM2060 IEEE 802.11a radio interfaces. It includes Encore DSP technology, and it supports a UART interface.
• The BCM4318E chip in the 144-pin package provides PCMCIA, Compact Flash, and SDIO/SPI bus interfaces. It includes Encore DSP technology.

Table 1 lists differences between the BCM4318 and BCM4318E chips and between the 144-pin and 196-pin packages.
