Product details
Overview
88MW300-B0-NAPI/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 full WLAN subsystem with integrated PA/LNA/switch. It operates on a single 3.3 V supply and supports XIP from external QSPI Flash-enabling compact IoT edge nodes like smart thermostats and wireless sensors.
For engineers reviewing the 88MW300-B0-NAPI/AZ datasheet, 88MW300-B0-NAPI/AZ pinout, 88MW300-B0-NAPI/AZ application, or 88MW300-B0-NAPI/AZ equivalent, key selection criteria include its 68-pin QFN package, absence of USB OTG, 35 GPIOs, dual GPTs, and support for Wi-Fi Direct, WPA2/WPA3 security, and deep-sleep power states down to 10 µA.
Technical Context
The 88MW300-B0-NAPI/AZ integrates a dedicated Feroceon-based WLAN subsystem (MAC/baseband/RF) that offloads real-time 802.11 protocol processing from the application CPU, enabling concurrent WLAN operation and application execution. Its direct-conversion 2.4 GHz RF architecture eliminates external SAW filters and includes integrated T/R switch, high-efficiency PA with 10 dB low-power mode, and on-chip AGC.
Power management employs independent domains, multiple low-power states (sleep, standby, shutoff), and an internal buck DC-DC converter generating 1.8 V for the WLAN subsystem. The Cortex-M4F application CPU runs at up to 200 MHz and accesses memory-mapped QSPI Flash via a 32 KB SRAM cache supporting execute-in-place (XIP).
