Atmel's New SmartRF Wireless Data Transceiver Dramatically Lengthens Battery Life and Cuts Chip Count

Grenoble, France - Atmel® Corporation (Nasdaq: ATML), announced today a new single-chip RF transceiver, providing high-level performance for ISM band applications, with notably lowered current consumption and a 30 percent cut in the low bill-of-materials. The ATA542x tranceiver family is targeting 315/345/433/868/915 MHz bands and represents a major step in the integration of RF transceivers. The Image Rejection Mixer allows elimination of a SAW filter, the Low-IF architecture does not require external IF filter, and the low loss integrated RX/TX switch eliminates need for an external switch. This typically allows 30 percent reduction in passive components versus current solutions.

A specific attention has been paid to maintaining low current consumption resulting in a 20 percent power reduction versus competing multi-channel transceivers. This makes the ATA542x devices a particularly suitable choice for long battery life applications such as automatic meter reading, alarm and security systems, home automation systems, and other wireless remote controllers and telemetry systems where low-power consumption and very long range are required.

"Our attention to low current consumption RF designs makes the ATA542x family a major step in license-free RF designs, with 10 mA in Rx and 15 mA to 20 mA in Tx," said Eric Mercier, Atmel's RF marketing and application leader for ISM RF products. "The fully green QFN package and its high integration allow easy and dense implementation. As with our other SmartRF tranceivers, the output power, +10 dBm, and the sensitivity, typical -107 dBm/FSK and –114 dBm/ASK, allow long-range communications. Our reference designs are available on request."

Additional features to ease the RF systems development include a SPI port and easy programming, a data rate up to 40 kbps, a bit-check in receive mode, a 16-byte data buffer in both Rx and Tx mode, a RSSI and a 4 MHz clock output to feed the companion microcontroller.

The ATA542x is available today and pricing starts at $1.8 in large quantities.
