Product details
Overview
88W8977-A1-NMVE/AZ from NXP Semiconductors is a dual-band 2.4/5 GHz Wi-Fi 4 (802.11n) and Bluetooth 5.2 combo SoC with simultaneous operation, 1×1 SISO RF architecture, SDIO 3.0 and UART host interfaces, and integrated coexistence arbitration for Wi-Fi/Bluetooth/ZigBee. It delivers up to 150 Mbps PHY data rate, supports 802.11mc indoor location, and targets compact wireless clients in smart home gateways and mobile routers.
For engineers reviewing the 88W8977-A1-NMVE/AZ datasheet, 88W8977-A1-NMVE/AZ pinout, 88W8977-A1-NMVE/AZ application, or 88W8977-A1-NMVE/AZ equivalent, key selection criteria include its QFN-68 package, dual-band concurrent operation capability, Bluetooth 5.2 Direction Finding (AoA), 802.11h DFS compliance, and support for WPA3 and 802.11e QoS in resource-constrained embedded designs.
Technical Context
The 88W8977-A1-NMVE/AZ integrates independent ARM-based Wi-Fi and Bluetooth CPUs with two-channel DMA, enabling true hardware-level concurrency. Its RF subsystem uses shared LNA for 2.4 GHz Wi-Fi/Bluetooth receive and separate 5 GHz transmit/receive paths via RF_TR_5, supporting Dynamic Rapid Channel Switching across bands.
Coexistence is managed through dedicated hardware arbitration (Wi-Fi/Bluetooth/ZigBee/MWS), programmable RF control pins (RF_CNTL0_N–RF_CNTL3_P), and multiplexed interfaces including SDIO 3.0, UART, PCM, and Bluetooth external coexistence signals (BT_REQ/BT_GRANTn). Power management includes on-chip LDO generating 1.05 V from 1.8 V and deep-sleep modes.
