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 two in-demand wireless arenas where standards are crucial:
- MCU Wireless 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 MCU Wireless Standards Support
Atmel MCU wireless 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 MCU Wireless 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 RFID Wireless Standards Support
Atmel RFID devices address the needs of contactless RFID products operating at 125 kHz, 134.2 kHz and 13.56 MHz bandwidth ranges and support the ISO 14443-B standard.
ISO/IEC 14443B is one of a series of standards that prescribe the working parameters for contactless IC cards used in international interchange, product authentication, patient safety, and customer loyalty applications. The Interface includes the signal characteristic between a proximity card and proximity coupling device using bi-directional communication supporting a range of up to 10 cm.
You need absolute security in your RFID applications. Atmel helps you ensure privacy protection with its ISO 14443-B standard-compliant CryptoRF®13.56 MHz RFID devices. These devices come with embedded 64-bit cryptographic engine, dual authentication capability, and up to 64 Kbits of memory, each with up to 16 individually configurable sectors. You can purchase CryptoRF for your RFID card modules, complete with RFID tags and thinned wafers.
Free Downloadable CryptoRF Wireless Software Stacks Atmel supports its CryptoRF RFID hardware with a comprehensive range of CryptoRF reference designs, demonstration kits and application software to speed implementation into existing products. CryptoRF APIs can be downloaded from the CryptoRF development library page.
