Product details
Overview
88MW320-A0-NAPE/AZ from NXP Semiconductors is a low-power, IEEE 802.11b/g/n WLAN microcontroller SoC featuring an ARM Cortex-M4F CPU (200 MHz), integrated 512 KB SRAM, 128 KB mask ROM, and a full WLAN subsystem with integrated PA/LNA/switch operating at 2.4 GHz. It supports QSPI Flash XIP via 32 KB SRAM cache and delivers up to 72.2 Mbps data rate in HT20 mode. Used in smart home thermostats and industrial Wi-Fi-to-bridge gateways.
For engineers reviewing the 88MW320-A0-NAPE/AZ datasheet, 88MW320-A0-NAPE/AZ pinout, 88MW320-A0-NAPE/AZ application, or 88MW320-A0-NAPE/AZ equivalent, key selection criteria include its 68-pin QFN package, 35 GPIOs, dual low-power domains, hardware AES-CCMP/WPA3 security engine, and absence of USB OTG-critical for cost-sensitive, battery-operated IoT endpoints requiring certified Wi-Fi connectivity without host-side USB dependency.
Technical Context
The 88MW320-A0-NAPE/AZ integrates two independent subsystems: a WLAN MAC/baseband/RF radio with direct-conversion architecture and integrated 2.4 GHz PA/LNA/T-R switch, and an application CPU subsystem built around the ARM Cortex-M4F core running at 200 MHz. Its RF path requires only a 38.4 MHz crystal and external low-pass filter, eliminating SAW filters.
Power management includes five distinct low-power states (idle, standby, sleep, shutoff, power-down), independent domain control, brown-out detection, and an internal buck DC-DC converter generating 1.8 V for the WLAN subsystem. The device supports secure boot, OTP memory for configuration storage, and hardware-accelerated WPA3 (SAE) and WAPI encryption.
