Wireless Technology Changing Our World
When Standards Compliance Matters
Efficient and effective wireless applications require standards-based technology, powerful transceivers that support a wide range of frequencies and devices that strike an optimum balance between high-performance and low power use. Atmel wireless technologies cover four in-demand wireless arenas where standards are crucial:
- 802.15.4 MCUs devices
- WIFI 802.11 MCU devices
- Bluetooth Low energy 4.x MCU devices
- RF Identification (RFID) devices
Note that Atmel also produces Smart RF devices that target proprietary (non-standards based) wireless industrial and consumer applications such as automatic metering, alarm systems, and home control applications, as well as toys and gaming applications.
Atmel 802.15.4 MCUs Standards Support
Atmel 802.15.4 MCUs devices address the needs of low-cost, low-power, low data rate IEEE 802.15.4 and ZigBee-compliant wireless control and sensor network applications such as wireless personal area networks (WPANs) and industrial, medical, building automation and safety applications.
The IEEE 802.15.4 standard defines the protocol and compatible interconnection for data communication devices using low data rate, low power and low complexity, short-range radio frequency (RF) transmissions.
ZigBee and RF4CE
ZigBee is an open, global, packet-based protocol designed to provide an easy-to-use architecture for secure, reliable, low power wireless networks. The ZigBee standard operates on the IEEE 802.15.4 physical specification for unlicensed radio bands operating at 2.4GHz, or 700/800/900MHz. Individual devices must have a battery life of at least two years to pass ZigBee certification.
The ZigBee RF4CE standard enhances the IEEE 802.15.4 standard by providing a simple networking layer and standard application profiles that can be used to create interoperable multi-vendor consumer electronic solutions.
Atmel offers a complete line of IEEE 802.15.4-compliant and ZigBee-certified wireless RF transceivers, AVR and ARM microcontrollers, single chip wireless microcontrollers, bundles, and full-featured Zigbit modules.
Data security is critical in wireless network applications, which is why the ZigBee RF4CE standard mandates 128-bit AES data encryption. But encoding and decoding processes take up valuable computing resources, slowing the performance of the chip. Atmel’s onboard crypto engines can speed encryption and decryption by 10 times, so devices spend less time processing. Because crypto can be added to high-speed communication without any performance impact, it is an ideal choice for wireless and battery-powered applications that require secure, encrypted communication plus low power consumption.
Free Downloadable 802.15.4 MCUs Software Stacks
Atmel supports its wireless MCU hardware with free, ready-to-use IEEE 802.15.4-compliant software stacks, such as IEEE 802.15.4 MAC, ZigBee RF4CE, ZigBee® PRO. In addition Atmel offers ZigBee Remote Control profile software and the BitCloud Profile software suite including a complete set of fully functional reference implementations for ZigBee Smart Energy, ZigBee Building Automation and ZigBee Home Automation. These tools help accelerate your smart energy, building automation, and home automation product development, and reduce your time to market. These software stacks can be downloaded from our IEEE 802.15.4 wireless software page .
Atmel WIFI 802.11 MCUs Standards Support
IEEE 802.11 is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN) computer communication. They are created and maintained by the IEEE LAN/MAN Standards Committee (IEEE 802).
The Atmel SmartConnect Wi-Fi portfolio is a family of self-contained, low-power, and certified modules bringing wireless Internet connectivity to any embedded design. These integrated modules offer the ideal solutions for designers seeking to integrate Wi-Fi connectivity without any 802.11, IP Stack or RF experience. SmartConnect Wi-Fi opens the door to the Internet of Things for a vast array of battery-powered devices and applications requiring the integration of WLAN connectivity without compromising on cost and power consumption.
Atmel's WILC Link controller offers multiple peripheral interfaces including UART, SPI, I2C, and SDIO, along with the associated cloud-ready connectivity software, making it the perfect wireless connectivity companion to any microprocessor (MPU) running Android or Linux MPUs.
The WINC network controller features embedded flash memory which allows the device to host network services stack and Wi-Fi stack for rapid design development. Additionally, the family offers an On-Chip Network Stack to minimize host CPU requirements. The Network features include TCP, UDP, DHCP, ARP, HTTP, SSL, and DNS. The WINC devices are optimized for IoT applications such as battery-powered devices, smart appliances, healthcare, home automation, consumer electronics, industrial automation and more. The WINC devices can be paired with any Atmel AVR® or Atmel | SMART MCU.
The Atmel SmartConnect portfolio also offers Stand-alone Wi-Fi IP (WILC1000/WINC1500/SAMW25) or combo WiFi-BT/BLE (WILC3000/WINC3400). Atmel's 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 network controller family offers an On-Chip Network Stack to minimize host CPU requirements. The Network features include TCP, UDP, DHCP, ARP, HTTP, SSL, and DNS. Optimized for IoT applications such as Battery-powered devices, Smart appliances, Healthcare, Home automation, Consumer electronics, Industrial automation and more.
