| 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.
