NXP® 88MW32X 802.11N WI-FI® MICROCONTROLLER SOC FACT SHEET
Several features of the NXP 88MW320/322 SoC enable low system costs and high WLAN protocol processing. For example, the high degree of integration in the SoC requires only one 3.3 V power input, a 38.4 MHz crystal and SPI flash, while the RF path needs only a low-pass filter for antenna connection. Proven and mature IEEE 802.11n/g/b NXP technology powers a full-featured WLAN subsystem in the SoC. This WLAN subsystem integrates a WLAN MAC, baseband, and direct-conversion RF radio with integrated PA, LINA and transmit/receive switch. It also integrates a CPU subsystem with integrated memory to run NXP WLAN firmware to handle real-time WLAN protocol processing to offload many WLAN functions from the main application CPU. An Arm® Cortex®-M4F CPU that operates up to 200 MHz powers the 88MW320/322 application subsystem. The device supports an integrated 512 KB SRAM, 128 KB mask ROM and a QSPI interface to external flash. An integrated flash controller with a 32 KB SRAM cache enables execute in place (XIP) support for firmware from flash.The SoC is designed for low-power operation and includes several low-power states and fast wake-up times. Multiple power domains and clocks can be individually shut down to save power. The SoC also has a high-efficiency internal PA that can be operated in low-power mode to save power. The microcontroller and WLAN subsystems can be placed into low-power states, independently, supporting a variety of application use cases. An internal DC-DC regulator provides the 1.8 V rail for the WLAN subsystem.The SoC provides a full array of peripheral interfaces including SSP/SPI/I²S (3x), UART (3x), I²C (2x), general-purpose timers and PWM, ADC, DAC, analog comparator, and GPIOs. It also includes a hardware cryptographic engine, RTC, and watchdog timer.The 88MW322 SoC includes a high-speed USB On-The-Go (OTG) interface to enable USB audio, video and other applications.A complete set of digital and analog interfaces enables direct interfacing for I/O and avoids the need for external chips. The application CPU can be used to support custom application development and avoids the need for another microcontroller or processor.
