NXP Semiconductors 88W8987-A2-NYEE/AK

Overview

88W8987-A2-NYEE/AK from NXP Semiconductors is a dual-band 2.4/5 GHz Wi-Fi 5 (802.11ac) and Bluetooth 5.2 System-on-Chip, supporting simultaneous independent operation at up to 433 Mbit/s (MCS9, 80 MHz), with integrated SDIO 3.0 and UART host interfaces, and operating across -30 to 85°C for extended-temperature embedded applications.

For engineers reviewing the 88W8987-A2-NYEE/AK datasheet, 88W8987-A2-NYEE/AK pinout, 88W8987-A2-NYEE/AK application, or 88W8987-A2-NYEE/AK equivalent, this page delivers verified SoC-level specifications, QFN package pin mapping, coexistence architecture details, and real-world integration guidance for mobile computing and IoT gateway designs.

Technical Context

The 88W8987-A2-NYEE/AK implements two independent ARM-based CPUs-one for Wi-Fi MAC/baseband (802.11ac/n/a/g/b) and one for Bluetooth 5.2 (Classic + LE)-with hardware-accelerated features including 802.11mc indoor positioning, DFS radar detection in 5 GHz bands, and explicit beamformee support. Its direct-conversion RF architecture eliminates external SAW filters.

It supports dual-path front-end configurations: the QFN variant uses separate 2.4 GHz and 5 GHz antenna paths with dedicated BRF_ANT and RF_TR_2/RF_TR_5 terminals, while enabling full Wi-Fi/Bluetooth coexistence arbitration via on-chip logic and shared clocking resources (XTAL_IN/XTAL_OUT, SLP_CLK_IN).

FAQ

What Wi-Fi standards does the 88W8987-A2-NYEE/AK support?

The 88W8987-A2-NYEE/AK supports IEEE 802.11a/b/g/n/ac (Wave 2), including 802.11h DFS, 802.11k/v/r roaming, 802.11e QoS, and 802.11mc indoor positioning. It achieves up to 433 Mbit/s at MCS9 (80 MHz channel, 1×1) and maintains backward compatibility with legacy 802.11b/g/n clients. The 88W8987-A2-NYEE/AK does not support 802.11ax (Wi-Fi 6) or 802.11be (Wi-Fi 7).

Does the 88W8987-A2-NYEE/AK support Bluetooth Low Energy (LE) features beyond version 5.2?

The 88W8987-A2-NYEE/AK implements Bluetooth 5.2 Core Specification features including 2 Mbit/s LE PHY, Data Length Extension, Advertising Extensions, and Secure Connections. It does not support Bluetooth 5.3 or 5.4 features such as LE Audio (LC3 codec), Isochronous Channels, or Periodic Advertising Sync Transfer. The 88W8987-A2-NYEE/AK supports up to 16 concurrent LE connections in Central+Peripheral topology.

What is the function of the PDn pin on the 88W8987-A2-NYEE/AK?

The PDn (Power-Down) pin is an active-low hardware control input that initiates a controlled low-power state, preserving register context and enabling fast wake-up. When asserted, it triggers internal power gating of non-essential blocks while maintaining RTC and wake-source logic. The 88W8987-A2-NYEE/AK supports programmable wake sources-including GPIO[12], GPIO[13], and SDIO interrupt-allowing selective host wake events without full chip reset.

Can the 88W8987-A2-NYEE/AK operate with a 40 MHz crystal instead of 26 MHz?

Yes, the 88W8987-A2-NYEE/AK supports both 26 MHz and 40 MHz fundamental-mode crystals via its XTAL_IN/XTAL_OUT interface. The internal fractional-N synthesizer automatically adapts to either reference frequency, ensuring accurate 2.4 GHz and 5 GHz channel generation. No firmware or register changes are required-crystal selection is handled at boot via hardware auto-detection (CONFIG_AUTO_REF_DET pin).

How many GPIOs are available on the 88W8987-A2-NYEE/AK, and what are their voltage domains?

The 88W8987-A2-NYEE/AK provides 21 general-purpose I/O pins (GPIO[20:0]), all operating at 1.8 V I/O voltage (VIO domain). Each GPIO supports configurable pull-up/pull-down, interrupt generation, and multi-function assignment-including JTAG, UART, and wake signaling. GPIO[15] and GPIO[14] double as independent Wi-Fi/Bluetooth reset lines, and GPIO[12]/GPIO[13] serve as dedicated out-of-band host wake signals.
