EZRadio chipset eyes new wireless applications

Jan 29, 2004 12:00 PM

Mountain View, Calif. -– Integration Associates has unveiled its EZRadio FSK (frequency shift keying) receiver/transmitter chipset, which will enable a new generation of low-cost, high-performance wireless applications for the toy, consumer electronics, automotive, and building security markets. EZRadio is the first to combine Automatic Antenna Tuning technology (patent pending) in an integrated RF chipset, which provides reliable connectivity for low-power, low data rate RF communications. In addition, EZRadio includes features designed to extend battery life and enable smaller end-user products.

In a separate announcement made last week, Integration Associates also said it has entered into an agreement with Sensory Inc., in which the two companies will co-market EZRadio with Sensory’s speech Recognition Synthesis and Control (RSC) chipset. By combining speech recognition and wireless connectivity, voice-activated wireless control will be offered at a price/performance point suitable for the toy and consumer electronics markets.

EZRadio can also wirelessly connect products such as home appliances, tire pressure sensors, PC peripherals and smoke detectors, to name just a few. Key features of EZRadio include:

  • Automatic Antenna Tuning eliminates the need for production line tuning costs and ensures optimal RF transmission throughout the product lifecycle.
  • Fully integrated on-chip RF features: requires only one external component, the crystal, reducing the bill of material (BOM) and simplifying the design-in process.
  • EEPROM and microcontroller modes supported: for simple applications, EEPROM mode allows complete data transmitter operation without requiring a microcontroller.
  • Key radio management functions, such as data recovery and timing, performed by EZRadio: does not require a microcontroller to execute those functions. If a microcontroller is needed for the application, a less expensive microcontroller will be sufficient.
  • Clock source available: does not require a second crystal if a microcontroller is used.
  • Software configurable frequencies: one design for global unlicensed RF standards.
  • Fast and reliable frequency hopping: counter interference and multipath fading: 100+ devices can be used in the same environment.
  • High-impedance loop antenna can be etched directly onto the circuit board: eliminates the need for a more expensive external antenna.
The EZRadio chipset consists of the IA4220 FSK transmitter and the IA4320 FSK receiver. Development and evaluation toolkits are also available.
  • FCC and ETSI ISM bands: 315MHz, 433MHz, 868MHz, 915MHz
  • Range: outdoors 100+ meters typical, indoors 40+ meters typical
  • Data rate: 256 kbps maximum bit rate
