Microchip and Powercast Debut World’s First RF Energy Harvesting Kit That Enables Battery-Free, Perpetually Powered Wireless Applications

Combination of Powercast’s RF Energy Harvesting System and Microchip’s eXtreme Low Power PIC® Microcontrollers Eliminates Batteries in a Wide Range of Applications

CHANDLER, Ariz., Oct. 26, 2010 [NASDAQ: MCHP] — Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, and Powercast Corporation, a leader in RF-based wireless power and energy harvesting technology, today announced the Lifetime Power® Energy Harvesting Development Kit for Wireless Sensors featuring PIC® microcontrollers with eXtreme Low Power (XLP) Technology. This kit, composed of a 3-watt Powercaster™ transmitter as the power source, two P2110 Powerharvester® receiver evaluation boards, two custom-designed wireless sensor boards, the XLP 16-bit Development Board pre-loaded with jointly developed application software, an IEEE 802.15.4 transceiver and other accessories, makes it easy to demonstrate and develop smart-energy, wireless-sensor applications that are reliably and perpetually powered by radio waves—eliminating the need for a battery. The included transmitter can wirelessly power sensor devices from more than 40 feet away.

The main challenges for the designers of wireless sensor applications fall into the categories of power, location and wireless communication. Combining Powercast’s RF transmitter and receiver energy-harvesting system, which broadcasts and converts RF energy into DC power, with Microchip’s XLP PIC microcontrollers, which provide the industry’s lowest power consumption in active and sleep modes, solves all three of these design challenges.

Power
Powercast’s RF energy harvesting system provides predictable and reliable power, using broadcasted RF energy for wire- and battery-free operation, or to wirelessly charge battery-based systems. In the Lifetime Power kit, the Powercaster transmitter broadcasts RF energy to the Powerharvester receiver, which can be embedded into an OEM’s micro-power device. The receiver then converts the RF energy and presents it as a regulated power supply to Microchip’s PIC24F microcontroller. The recently announced Powercast transmitter included in the kit is approved by the FCC (Part 15) and Industry Canada.

Location
Using broadcasted RF energy as the application’s sole power source allows for untethered and battery-free operation in hazardous or inaccessible locations, which would otherwise require labor-intensive or potentially dangerous battery maintenance. Additionally, broadcasted RF energy is controllable (can be scheduled, continuous or on-demand) and works in locations where other potentially intermittent energy-harvesting sources (e.g., solar, vibration and heat) make them unreliable.

Wireless Communication
Microchip’s configurable MiWi™ and MiWi P2P stacks are efficient and save power by enabling only the most essential wireless communication features. In addition to these proprietary Microchip protocols, the kit’s included MRF24J40 IEEE 802.15.4 transceiver also supports Microchip’s ZigBee stacks. From a functional standpoint, Microchip’s RF transceiver allows for continual readings of sensor data, portability and much easier installation than wired communication provides.
In addition to solving these three major challenges, the Lifetime Power kit provides modular development with Microchip’s included XLP 16-bit Development Board. This flexible platform allows customization for developing applications, and enables faster evaluation, prototyping and time to market.

Availability and Pricing
The Lifetime Power Energy Harvesting Development Kit for Wireless Sensors is available today for $1250 from Powercast’s distributors, including microchipDIRECT.

Powercast Transmitter Sends Power, Data for RF Energy Harvesting & Wireless Power Systems

Press Release

Powercast Transmitter Sends Power, Data for RF Energy Harvesting & Wireless Power Systems

Transmitter and receiver combo wirelessly charge and operate micro-power devices.

Pittsburgh, PA — October 19, 2010 — Powercast Corporation, a leader in RF-based wireless power and energy harvesting technology, today announced availability of its TX91501 Powercaster™ Transmitter which uses the 915-MHz ISM band to transmit common radio waves for power and data in commercial, industrial and defense applications. As the power source for Powercast’s RF energy-harvesting wireless power solution, the TX91501 broadcasts power and data over 40 feet to its companion Powerharvester® receivers. Embedded into micro-power devices such as wireless sensors, instrumentation and controls, the Powerharvester receivers convert the received RF energy into DC power for battery-free operation or to wirelessly trickle charge batteries. The receivers also output the data broadcast from the TX91501 as well as the received signal strength indication (RSSI).

Initial versions of the TX91501 transmitter will broadcast a unique ID for device authentication or location-tracking applications, while future versions will also transmit data such as timestamps for end-device synchronization and control.

Powercast’s TX91501 transmitter is approved by the FCC (Part 15) and Industry Canada. It can be used to broadcast RF energy for both power and data in numerous energy-harvesting applications such as environmental monitoring, building automation, energy management and industrial monitoring.

The RF signal uses Direct Sequence Spread Spectrum (DSSS) modulation for power and Amplitude Shift Keying (ASK) modulation for data. The TX91501 is available in versions with an output of 1 watt or 3 watts Effective Isotropic Radiated Power (EIRP).

The 6.75” H x 6.25” W x 1.63” D transmitter includes an integrated 8dBi directional antenna with a 60-degree beam pattern, and the unit mounts easily on either vertical or horizontal surfaces using one of two DC power jacks (bottom or back) and multiple mounting holes. The TX91501 operates immediately when powered on and requires no user configuration or programming. An internal shut-off mechanism automatically stops transmission when objects come close to the device, and an LED indicates transmission status.

Broadcasted RF energy creates a perpetual power source, unlike potentially unreliable solar, heat or vibration energy sources, to provide power-over-distance, one-to-many charging, and controllable wireless power (continuous, scheduled or on-demand). A wire- and battery-free power source enables zero-maintenance devices which deploy to inaccessible locations, and embeds within sealed devices for use in wet or harsh environments.

The 1-watt ($235) and 3-watt ($300) versions of theTX91501 Powercaster transmitter are available through Powercast’s authorized distributors.
