Enable Smart Connectivity

Highly integrated, low-power WLAN Microcontroller Soc solution

88MW300/302 Wi-Fi Microcontroller SoC

The Marvell® 88MW300/302 Wi-Fi Microcontroller system-on-chip (SoC) is industry’s first true, highly integrated, low-power chip with a full-featured micro controller built using ARM Cortex-M4F CPU and 802.11 b/g/n Wi-Fi. Designed to support the specific needs of Internet-of-Things (IoT) applications, the SoC is optimized for:

  • Simplifying development of IoT devices and their integration with IoT platforms and mobile applications
  • Low system cost
  • Low-power operation including enabling battery operated devices
  • Secure operation
  • Enabling feature rich functionality enabling manufacturers to create innovative, differentiated products and services

Key Features and Benefits

  • Secure boot based on hardware root of trust enabling complete, multi-layered security solution to provide secure persistent storage and communications.
  • A flexible memory architecture with generous 512kB SRAM and an accelerated flash controller providing memory-mapped access to external QSPI flash enabling IoT devices to be built with full-featured communication protocols, stacks and support integrations into multiple platforms and ecosystems.
  • Low-power optimizations enabling deep low-power states and reduced power-consumption in active modes to enable battery-powered applications.
  • Very low RBOM requiring only a single crystal, QSPI flash, and antenna with a single input power rail. A QFN package enables low PCB cost.
  • Easy interfacing to sensors, actuators, and other components via a full set of I/O interfaces including SPI, I2C, UART, I2S, PWM, ADC, DAC reducing extra components and PCB footprint.
  • Audio and video streaming enabled in any IoT device via a powerful Cortex-M4F CPU with DSP and Floating-point support, large SRAM, and high-speed IO interfaces.
  • Production quality software SDK providing libraries for networking middleware (HTTP, TLS, BSD Sockets, MQTT, Web-Sockets, JSON, XML, etc.), easy connection to Wi-Fi networks, Secure over-the-air (OTA) firmware update, persistent storage, and more.
  • Tools and documentation to facilitate hardware and software development and optimizations, and help customers through manufacturing and certifications to bring products to market quickly.
