MARVELL 88W8977 OVERVIEW
 
The Marvell® 88W8977 is a highly integrated WLAN (2.4/5 GHz) and Bluetooth single-chip solution,
specifically designed to support the speed, reliability, and quality requirements of next generation products.
The System-on-Chip (SoC) provides both simultaneous and independent operation of the following:
• IEEE 802.11n compliant, 1x1 spatial stream with data rates up to MCS 7 (150 Mbps)
• Bluetooth 4.2, as well as future Bluetooth 5.0 features (includes Bluetooth Low Energy (LE))
• 3-way coexistence for WLAN, Bluetooth, and ZigBee operation with Marvell ZigBee solutions
• Indoor location and navigation (802.11 mc and BLE Angles)
Internal coexistence arbitration and a Mobile Wireless Systems (MWS) serial transport interface provide the
functionality for connecting an external Long Term Evolution (LTE) or ZigBee device.
For security, the device supports high performance 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), 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. The device also
supports 802.11h Dynamic Frequency Selection (DFS) for detecting radar pulses when operating in the
5 GHz range.
Generic interfaces include SDIO 3.0 and high-speed UART interfaces for connecting WLAN and Bluetooth
technologies to the host processor.
The device is available in QFN and eWLP package options.
