外置flash，如何防止产品被人轻易“批量”复制？

未来值钱的东西都在服务器端，终端估计都免费了，更何况里面的程序。程序员要改变观念了。

做通用MCU用，由于CPU Core属于小众，估计不是很方便，如果编译器足够强大另说。
但是WIFI+BT的组合确实感 ...

有没实际接触过，wifi和BT可以同时使用么？

很简单的一个例子，手机的WIFI和BT就可以同时使用。但这个同时使用是个假像，有几种不同的手段可以实现这种复用，比如时分复用模式等，你可以去网上看下，有些资料介绍。

介绍一下这个芯片呀，想了解了解

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

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.

The 88MW300/302 SoC enables smart connectivity to a broad range of devices such as thermostats, air conditioners, appliances, lighting controls, mobile clients, cloud services, and other devices on the Internet of Things including:

White goods/appliances: refrigerator, washer, dryer, oven range, microwave, dishwasher, water, heater, air conditioner
Consumer devices and accessories: toys, speakers, headset, alarm clock, gaming accessory, remote control
Home automation: smart outlet, light switch, security camera, thermostat, sprinkler controller, sensor, door lock, door bell, garage door, security system
Personal health devices: weighing scale, glucometer, blood pressure monitor, fitness equipment
IoT/wearables: coffee pot, rice cooker, vacuum cleaner, air purifier, smart watch, fitness bracelet, pet monitor
Commercial/industrial: lighting, building automation, asset management, Point of Sale (POS)
Gateways: Connecting IR, sub-Gig or Legacy RF, Bluetooth Smart, ZigBee, ZWave and other radios to Wi-Fi/IP network
