RFM ADDS TO ITS LINE OF 802.15.4 RADIO MODULE PRODUCTS
Delivering Serial and I/O Data, Auto-Reporting, and I/O Binding

DALLAS, TEXAS, (June 1, 2009) RF Monolithics, Inc. (RFM. [NASDAQ: RFMI]) announced today the LPR2430 Series of Radio Frequency (RF) transceiver modules, adding to its 802.15.4 wireless sensor networking line of products for original equipment manufacturers (OEMs). Comprised of the low-power 1mW RF power LPR2430 and LPR2430A modules and the extended range 100mW RF power LPR2430ER and LPR2430ERA modules, the RFM LPR2430 Series modules provide the flexibility and versatility to serve a variety of applications, from simple cable replacement to remote terminal data collection to sophisticated sensor networks. Peer-to-peer, point-to-point, and point-to-multipoint networks are supported.

Target applications include security systems, medical patient telemetry, and medical lab equipment monitoring / control, smart grid and smart buildings for automation and control, environmental monitoring, cold chain / food safety monitoring wireless sensor networks, and industrial monitoring.

“With the release of this enhanced series of 802.15.4 compliant modules, RFM has responded to customers that desire more sophisticated functionality than what most other 802.15.4 standards-based modules in the market provide,” said Tim Cutler, RFM’s Director of Product Marketing for RF module products. “RFM has designed an 802.15.4 radio module with features that enable design engineers to configure the module to do exactly what they need it to do without having to write their own code. The result is rapid integration, shortened time-to-market, and overall lower engineering design costs.”

Multifaceted I/O Capabilities:

Standard UART interface for serial communications plus 6 GPIO, 3 ADCs, and 2 DACs (PWMs);
With the I/O Binding feature, one node has the ability to output on 2 GPIO lines the input value of 2 GPIO lines from another node; I/O Binding supports outputting the input value of one of the ADC lines from one node on the DAC (PWM) line of another node; one of the nodes can be the base node but is not required to be a base node; and
Firmware features and functions make it easy for the designer to make full use of module I/O.

Full Sensor Functionality:

Auto-reporting features allow many sensor nodes to be built without a dedicated microcontroller - the micro-controller on the module does all the work;
Auto-reporting mode provides module I/O updates based on timer or interrupts - without the need for the application to poll or otherwise request data; and
Interrupts are generated by edge-triggered events or by exceeding user-defined limits on ADC values - and any interrupt can be used to wake a sleeping mode and have the module send its I/O data.

Relay Function Avoids Obstructions:

Unique one-hop relay function that allows one node to send data to the base radio through another node; and
Relay is only used when the node cannot communicate directly with the base and doesn’t burden the entire network with the complexity and latency of a full mesh.

Designers save additional time and money by eliminating the need to receive regulatory certifications because the LPR2430 Series of modules is fully regulatory-agency certified for the US (FCC), Canada (IC) and Europe (ETSI). The LPR2430 is pin-for-pin compatible with RFM’s ZigBee, 802.11g WiFi®, and TSMP modules giving designers the ability to offer multiple radio technologies for products using a single design.

Developer kits will be available by early July 2009 from RFM distributors Avnet, Digi-Key, Mouser Electronics, and Nu Horizons.
