Atmel Expands SmartConnect Wireless Portfolio with a Cloud-Ready Wi-Fi/Bluetooth Combo Platform for IoT Applications

atmelAtmel announced the new SmartConnect WILC3000 and WINC3400. The WILC3000 and WINC3400 providing the highest IEEE® 802.11 b/g/n RF/Baseband/MAC and Bluetooth Smart Ready integration including Atmel’s patented adaptive co-existence engine.

The new, fully-integrated WILC3000 wireless link controller combines Wi-Fi 802.11n and Bluetooth Smart Ready technologies in an ultra-small 4.1×4.1mm Wafer Level Chip Scale Package (WLCSP) with lower power consumption, along with Atmel’s patented adaptive co-existence engine, making it the ideal solution for IoT and wearable applications.  Atmel’s WILC3000 Wi-Fi solution offers multiple peripheral interfaces including UART, SPI, I2C, and SDIO, and along with the associated cloud-ready connectivity software, making it the perfect wireless connectivity companion to any microprocessor (MPU) running Android or Linux MPUs.

Atmel is also introducing the WINC3400 network controller featuring embedded flash memory which allows the device to host network services stack, Wi-Fi stack, and Bluetooth Smart profiles for rapid design development with no wireless expertise required from the designer. The WINC3400 can paired with any Atmel AVR® or Atmel | SMART MCUs.

Atmel’s new Wi-Fi/Bluetooth combo solutions are optimized for low-power applications, supporting single-stream 802.11n mode providing up to 72 Mbps throughput allowing a broad range of use cases. Both products integrate a power amplifier, LNA, switch and power management unit providing developers with the highest level of integration together with the best link budget for maximum range.

The WILC3000 and WINC3400 provide the highest integration for a lower bill of material. The only external clock sources required is a high-speed crystal or oscillator with a wide range of reference clock frequencies supported (14-40 MHz) and a 32.768 kHz clock for sleep operation.

The WINC 3400 network controller offers an On-Chip Network Stack to minimize host CPU requirements. The Network features include TCP, UDP, DHCP, ARP, HTTP, SSL, and DNS. Additionally, the WINC3400 SiP includes Bluetooth Smart profiles allowing connection to advanced low energy applications such as smart energy, consumer wellness, home automation, security, proximity detection, entertainment, sports and fitness and automotive. It also supports Atmel’s cloud-ready software for simple cloud connectivity.
