Avastar 88W8977

A highly integrated WLAN (2.4/5 GHz) and Bluetooth single-chip solution

Avastar 88W8977 System-on-Chip

The Marvell® 88W8977® System-on-Chip (SoC) is a highly integrated single-chip solution that incorporates both WLAN (2.4/5 GHz) and Bluetooth® technology, and the SoC is specifically designed to support the speed, reliability, and quality requirements of next generation products. An IEEE 802.11n compliant dual band system-on-chip offering Wi-Fi data rates up to MCS 7 (150 Mbps), the 88W8977 is designed to offer the smallest footrprint and lowest bill of materials (BoM) for devices such as Wearables,  Internet of Things (IoT) and Smart Home markets. The SoC provides both simultaneous and independent operation of the IEEE 802.11n compliant 1x1 spatial stream and Bluetooth v4.2, as well as planned enhancements of Bluetooth technology including features such as higher speeds, and mesh networking for increased Internet of Things (IoT) functionality. It also provides for 3-way coexistence for WLAN, Bluetooth, and ZigBee operation with Marvell ZigBee Solutions.
