The 88W8987 is a highly integrated Wi-Fi (2.4/5 GHz) and Bluetooth single-chip solution,
specifically designed to support the speed, reliability, and quality requirements of next
generation Very High Throughput (VHT) products.
The System-on-Chip (SoC) provides both simultaneous and independent operation of the
following:
• IEEE 802.11ac (Wave 2), 1x1 with data rates up to MCS9 (433 Mbit/s)
• Bluetooth 5.2 (includes Bluetooth Low Energy (LE))
The SoC also provides:
• Bluetooth Classic and Bluetooth LE dual (Smart Ready) operation
• Wi-Fi indoor location positioning (802.11mc)
For security, the device supports high performance 802.11i security standards through
implementation of the Advanced Encryption Standard (AES)/Counter Mode CBCMAC
Protocol (CCMP), AES/Galois/Counter Mode Protocol (GCMP), 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.
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 designed with two front-end configurations to accommodate Wi-Fi and
Bluetooth on either separate or shared paths:
• 2-antenna configuration—1x1 Wi-Fi and Bluetooth on separate paths (QFN)
• 1-antenna configuration—1x1 Wi-Fi and Bluetooth on shared paths (eWLP)
The following figures show the application diagrams for each package option.
