Product details
Overview
88MW300-B0-NAPE/AZ from NXP Semiconductors is a low-power WLAN microcontroller SoC integrating IEEE 802.11b/g/n (2.4 GHz, 1×1 SISO), ARM Cortex-M4F CPU at 200 MHz, 512 KB SRAM, 128 KB mask ROM, and hardware cryptographic acceleration. It supports Wi-Fi Direct, WPA2/WPA3 security, and operates in extended temperature range (–30 °C to +85 °C) for smart home sensor nodes.
For engineers reviewing the 88MW300-B0-NAPE/AZ datasheet, 88MW300-B0-NAPE/AZ pinout, 88MW300-B0-NAPE/AZ application, or 88MW300-B0-NAPE/AZ equivalent, this page delivers verified package mapping (68-pin QFN, 8×8 mm), confirmed WLAN RF interface (RF_TR), validated low-power modes (sleep/shutoff), and real-world IoT use-case alignment - no extrapolation, no generic claims.
Technical Context
The 88MW300-B0-NAPE/AZ implements a dual-subsystem architecture: a dedicated Feroceon-based WLAN MAC/baseband/RF subsystem with integrated PA, LNA, and T/R switch handles real-time 802.11 protocol processing, while the ARM Cortex-M4F application CPU runs custom firmware independently. Both subsystems feature isolated power domains and independent low-power state control.
Its WLAN subsystem uses direct-conversion RF architecture with fractional-N LO, supports HT20 channels, and integrates AES-CCMP, TKIP, and CMAC engines compliant with 802.11i/w/d/e/h/k/r standards. The application subsystem includes QSPI Flash controller with 32 KB SRAM cache enabling XIP execution, plus analog peripherals (12-bit/2 MSps ADC, 10-bit DAC, comparators) and digital interfaces (3× UART, 3× SSP, 2× I²C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Wireless Standard | IEEE 802.11b/g/n, 2.4 GHz, 1×1 SISO, HT20, max 72.2 Mbps - enables cost-effective Wi-Fi connectivity without external RF front-end components. |
| CPU Core | ARM Cortex-M4F @ 200 MHz - delivers deterministic real-time processing for concurrent application + network stack execution. |
| On-chip Memory | 512 KB SRAM + 128 KB mask ROM - eliminates need for external RAM in most firmware deployments; ROM hosts boot loader and WLAN firmware. |
| Security Engine | Hardware AES-CCMP, TKIP, CMAC, WAPI, SAE (WPA3) - offloads encryption/decryption from CPU and ensures compliance with enterprise-grade Wi-Fi security protocols. |
| Power Modes | Active, idle, standby, sleep, shutoff, power-down - enables sub-μA deep-sleep current with wake-up via GPIO, RTC, or IRQ, critical for battery-powered sensors. |
| Operating Temp | –30 °C to +85 °C (extended grade) - qualified for deployment in uncontrolled indoor environments like HVAC units and smart appliances. |
| Package | 68-pin QFN, 8×8 mm, 0.4 mm pitch - surface-mount compatible with standard reflow profiles; thermal pad improves heat dissipation under sustained WLAN transmit load. |
Pinout & Package
68-pin QFN package (8 mm × 8 mm, 0.4 mm pitch) with exposed thermal pad. Pin 17 is ground-connected per mechanical specification. Dedicated pins include RF_TR (WLAN RF I/O), RESETn, XTAL_IN/OUT (38.4 MHz crystal), and VBAT_IN. All other signals are multiplexed on GPIOs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RF_TR | WLAN RF Transmit/Receive | Direct 2.4 GHz antenna interface; requires only external low-pass filter - no SAW or balun needed due to integrated PA/LNA/T-R switch. |
| RESETn | Active-low Reset Input | Asynchronous system reset; asserted low for ≥100 ns to initialize both WLAN and application subsystems. |
| XTAL_IN / XTAL_OUT | 38.4 MHz Crystal Interface | Drives internal PLL for WLAN baseband and CPU clock generation; supports CMOS or low-swing sine wave input. |
| GPIO_0–GPIO_10, GPIO_16, GPIO_22–GPIO_33, GPIO_39–GPIO_49 | Multiplexed Digital I/O | 35 total GPIOs supporting UART, SSP, I²C, GPT, ADC/DAC triggers, and wake-up functions - reduces BOM count by eliminating level shifters or bus expanders. |
| VDDIO_0–VDDIO_3, AVDD18, AVDD33, VBAT_IN | Power Supply Inputs | Dual-domain supply: 3.3 V for I/O and RF, 1.8 V for analog/RF core (generated internally); VBAT_IN enables backup power for RTC during main supply loss. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated WLAN Subsystem | Full MAC/baseband/RF with PA, LNA, and T/R switch - eliminates discrete RF front-end, reducing PCB area and RF tuning effort. |
| XIP-capable QSPI Flash Controller | 32 KB SRAM cache enables direct code execution from external SPI Flash - avoids SRAM footprint constraints for large OTA update images. |
| Secure Boot + Hardware Crypto | Mask ROM enforces authenticated boot chain; AES/CMAC engines accelerate TLS handshake and secure firmware updates. |
| Low-Power Architecture | Independent power domains for WLAN and MCU allow selective shutdown - e.g., WLAN in sleep while MCU monitors sensor inputs at <10 μA. |
| Analog Peripherals | 12-bit/2 MSps ADC with PGA, 10-bit DAC, and dual comparators - supports local signal conditioning for temperature, pressure, or battery monitoring without external ICs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 88MW302-A0-NAPE/AZ | 88-pin QFN, adds USB 2.0 OTG, 50 GPIOs, 4 GPTs - larger footprint and higher pin count. | Required when USB audio/video bridging or host-mode peripheral attachment is needed. | Select 88MW302-A0-NAPE/AZ only if USB OTG functionality is mandatory; otherwise 88MW300-B0-NAPE/AZ offers lower cost and smaller layout. |
| ESP32-WROOM-32 | 2.4 GHz Wi-Fi + Bluetooth 4.2, dual-core Xtensa LX6, 4 MB Flash onboard, no integrated PA - requires external matching network. | Better suited for dual-radio (Wi-Fi + BLE) use cases and rapid prototyping with Arduino/ESP-IDF ecosystem. | Choose ESP32-WROOM-32 for mixed-protocol designs or where open-source toolchain support outweighs NXP's hardened WLAN stack and industrial temp grade. |
Compared with 88MW302-A0-NAPE/AZ, the 88MW300-B0-NAPE/AZ saves board space and BOM cost by omitting USB OTG while retaining identical WLAN performance and security features; versus ESP32-WROOM-32, it provides superior RF integration, extended temperature qualification, and deterministic real-time WLAN offload - critical for certified industrial deployments.

FAQ
What wireless standards does the 88MW300-B0-NAPE/AZ support?
The 88MW300-B0-NAPE/AZ supports IEEE 802.11b/g/n in the 2.4 GHz ISM band with 1×1 SISO configuration and HT20 channel bandwidth. It implements full protocol stacks including WPA2 (AES-CCMP), WPA3 (SAE), 802.11d/e/h/k/r/w, and Wi-Fi Direct - all handled in hardware by its dedicated WLAN subsystem, not the Cortex-M4F CPU.
Does the 88MW300-B0-NAPE/AZ include an integrated power amplifier?
Yes, the 88MW300-B0-NAPE/AZ integrates a high-efficiency RF power amplifier (PA) within its WLAN subsystem. It supports a low-power mode (10 dB gain setting) and full transmit power mode, eliminating the need for external PA components and simplifying RF front-end design for compact IoT modules.
What is the maximum operating frequency of the application CPU in the 88MW300-B0-NAPE/AZ?
The application CPU in the 88MW300-B0-NAPE/AZ is an ARM Cortex-M4F core running at up to 200 MHz. This clock speed is achieved using the internal PLL driven by the 38.4 MHz crystal, and it remains stable across the full –30 °C to +85 °C operating temperature range.
How many GPIOs does the 88MW300-B0-NAPE/AZ provide, and are they configurable?
The 88MW300-B0-NAPE/AZ provides 35 GPIOs mapped across pins GPIO_0 to GPIO_10, GPIO_16, GPIO_22 to GPIO_33, and GPIO_39 to GPIO_49. All GPIOs are highly configurable - supporting UART, SSP, I²C, GPT, ADC triggers, comparator outputs, and wake-up functions - with programmable pull-up/down and drive strength.
Is USB OTG supported on the 88MW300-B0-NAPE/AZ?
No, USB OTG is not supported on the 88MW300-B0-NAPE/AZ. That interface is exclusive to the pin-compatible 88MW302 variant (88-pin QFN). The 88MW300-B0-NAPE/AZ omits USB OTG circuitry to reduce cost and package size - making it ideal for Wi-Fi-only applications where USB connectivity is unnecessary.
