FAQ

What is the package type and dimensions of the 88W8977-A1-EADE/AZ?

The 88W8977-A1-EADE/AZ uses a 74-bump eWLP (enhanced Wafer-Level Package) measuring 4.674 mm × 3.46 mm with 0.4 mm pitch. This flip-chip package provides superior thermal performance and minimal PCB footprint compared to QFN alternatives, making it ideal for wearables and compact gateways where board space is constrained. The package is qualified for industrial temperature operation (-40°C to +85°C).

Does the 88W8977-A1-EADE/AZ support both Wi-Fi and Bluetooth simultaneously with full independence?

Yes, the 88W8977-A1-EADE/AZ supports true simultaneous and independent operation of Wi-Fi 4 (802.11n) and Bluetooth 5.2 through dedicated ARM-based CPUs, separate two-channel DMA controllers, and hardware coexistence arbitration. This architecture prevents protocol stack interference, enabling concurrent voice-over-Wi-Fi, BLE sensor telemetry, and 802.11mc location reporting without software scheduling overhead.

What host interfaces does the 88W8977-A1-EADE/AZ provide for connecting to a host processor?

The 88W8977-A1-EADE/AZ provides SDIO 3.0 (4-bit mode) and high-speed UART as primary host interfaces. SDIO 3.0 supports up to 208 MB/s throughput for high-bandwidth Wi-Fi/Bluetooth data transfer, while UART offers hardware flow control (RTS/CTS) for debug, provisioning, or fallback communication. Both interfaces are electrically isolated and support independent power domains (VIO_SD and VIO).

How does the 88W8977-A1-EADE/AZ handle coexistence with LTE or other radios?

The 88W8977-A1-EADE/AZ implements hardware-based coexistence arbitration via dedicated BT_REQ, BT_GRANTn, BT_STATE, and BT_FREQ pins, plus an MWS serial transport interface. These signals enable deterministic time-slicing with LTE modems without host CPU intervention, reducing latency and packet loss. The SoC also supports 802.11h DFS to avoid radar-contested 5 GHz channels in real time.

What security protocols are supported by the 88W8977-A1-EADE/AZ for Wi-Fi and Bluetooth?

The 88W8977-A1-EADE/AZ supports WPA3 (SAE), WPA2 (AES/CCMP), WPA/WPA2 mixed mode, WEP/TKIP, WAPI, and 802.11w protected management frames for Wi-Fi. For Bluetooth, it implements AES encryption, LE Secure Connections, and Bluetooth 5.2 privacy extensions. All cryptographic operations are hardware-accelerated to minimize host CPU load and ensure real-time performance.
