Farsens unveils development platform for battery-free wireless sensors and actuators

Farsens has introduced the Medusa development platform for UHF RFID battery-free devices. The Medusa includes an ANDY100 chip with EPC C1G2 communication and a MSPG2233IPW20 microcontroller from Texas Instruments for communication with developers’ circuits.

Users can now develop their own wireless sensors or actuators without requiring batteries on the tag. The Medusa harvests energy from the RF field created by the RFID reader to power up the ANDY100 IC, the microcontroller and the circuitry and devices attached to it.

The ANDY100 chip included works under standard EPC C1G2 commands so no proprietary or custom commands are needed. Any commercial UHF RFID reader can be used just by programming with the correct standard commands.

Key features of the Medusa development platform:

• Compatible with EPC C1G2 readers
• 2kB Flash, 256B SRAM
• 16xGPIO (12 free, 4 for ANDY100)
• 2x16bit Timer
• Watchdog Timer
• 10 bit SAR ADC with 8 channel multiplexer
• Communication range: 1.5 meters (5 feet)
• No batteries needed – increased communication range when batteries are used
• 96-EPC bits
• 860-960 MHz
• PCB format
• Operating temperature: -30°C to +85°C (-22°F to +185°F).

Evaluation kits are now available on the Farsens online store.

Farsens designs and manufactures full passive RFID sensor solutions. Its proprietary UHF RFID IC allows Farsens to develop long range solutions for asset tracking – via the unique ID – and monitoring – via the attached sensor – without the need of any battery on the tag.
