88MW320 Datasheet | NXP Semiconductors

OVERVIEW The 88MW320/322 is a highly integrated, low-power WLAN Microcontroller System-on-Chip (So C) solution designed for a broad array of smart devices for home, enterprise and industrial automation, smart accessories, and smart energy applications. A high degree of integration enables very low system costs requiring only a single 3.3V power input, a 38.4 MHz crystal, and SPI Flash. The RF path needs only a low pass filter for antenna connection. The So C includes a full-featured WLAN subsystem powered by proven and mature IEEE 802.11b/g/n technology. The WLAN subsystem integrates a WLAN MAC, baseband, and direct-conversion RF radio with integrated PA, LNA, 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 off-load many WLAN functions from the main application CPU. The 88MW320/322 application subsystem is powered by an ARM Cortex-M4F CPU that operates up to 200 MHz. 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 e Xecute In Place (XIP) support for firmware from Flash. The So C 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 So C 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 1.8V rail for the WLAN subsystem. The So C provides a full array of peripheral interfaces including SSP/SPI/I2S (3x), UART (3x), I2C (2x), General Purpose Timers and PWM, ADC, DAC, Analog parator, and GPIOs. It also includes a hardware cryptographic engine, a Secure Boot element, RTC, and Watchdog Timer. The 88MW322...
