Marvell Avastar 88W8766P Integrated
WLAN/Bluetooth Single-Chip SoC
Supports PCIe v3.0 and USB 2.0 Interfaces for Connecting to the Host Processor
PRODUCT OVERVIEW
The Marvell® Avastar™ 88W8766P is a highly integrated wireless local area network (WLAN) system-on-chip (SoC),
specifically designed to support high throughput data rates for next generation WLAN products. The device is
designed to support IEEE 802.11a/g/b and 802.11n payload data rates. The device also supports Bluetooth
4.0+High Speed (HS) and Bluetooth Low Energy (BLE).
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 with integrated 2.4 GHz PA and T/R switch on a single chip.
For security, the 88W8766P 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 88W8766P supports PCIe v3.0 (2.5 Gbps) and USB 2.0 interfaces for connecting WLAN and Bluetooth activity
respectively to the host processor.
The device is available in a QFN package.
