1 Product overview
The 88W8977 System-on-Chip (SoC) is a highly integrated single-chip solution that
incorporates both Wi-Fi
®
(2.4/5 GHz) and Bluetooth
®
technology. 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 MCS7 (150 Mbps)
• Bluetooth 5 (includes Bluetooth Low Energy (LE))
The SoC also provides 3-way coexistence for Wi-Fi, Bluetooth, and ZigBee operation,
and indoor location and navigation (802.11mc).
The 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. The device also supports a coexistence interface for
co-located Bluetooth/Wi-Fi device arbitration.
For security, the device supports high performance 802.11i security standards through
the 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), WPA (AES),
and Wi-Fi Authentication and Privacy Infrastructure (WAPI) security mechanisms.
For video, voice, and multimedia applications, 802.11e Quality of Service (QoS) is
supported. The device also features 802.11h Dynamic Frequency Selection (DFS) for
detecting radar pulses when operating in the 5 GHz range.
Host interfaces include SDIO 3.0 and high-speed UART interfaces for connecting Wi-Fi
and Bluetooth technologies to the host processor.
The device is available in QFN and eWLP package options.
