8782WiFi模塊
The Marvell Avastar™ 88W8782 is a highly integrated wireless local area network (WLAN) system-on-chip (SoC),
specifcally designed to support high throughput data rates for next generation WLAN products and is part of the
Marvell Avastar family of wireless devices. The Avastar family includes single-function and multi-function radios that
establish new industry benchmarks for power consumption, wireless performance, solution footprint and
advanced features.
The Marvell Avastar 88W8782 is designed to support IEEE 802.11a/g/b and 802.11n payload data rates. The device
provides the combined functions of Direct Sequence Spread Spectrum (DSSS) and Orthogonal Frequency Division
Multiplexing (OFDM) baseband modulation, Medium Access Controller (MAC), CPU, memory, host interfaces, and
direct-conversion WLAN RF radio on a single integrated chip.
For security, the 88W8782 supports 802.11i security standards through implementation of the Advanced Encryption
Standard (AES)/Counter Mode CBC-MAC Protocol (CCMP), Wired Equivalent Privacy (WEP) with Temporal Key
Integrity Protocol (TKIP), Advanced Encryption Standard (AES)/Cipher-Based Message Authentication Code (CMAC),
and WLAN Authentication and Privacy Infrastructure (WAPI) security mechanisms.
For video, voice, and multimedia applications, 802.11e Quality of Service (QoS) is supported. Also supported are
802.11h Dynamic Frequency Selection (DFS) for detecting radar pulses when operating in the 5 GHz range.
The device is also equipped with a coexistence interface for external, co-located 2.4 GHz radios.
The 88W8782 supports generic interfaces including SDIO and G-SPI for connecting WLAN activity to the host
processor. Available packaging includes QFN and TFBGA options.
