HEILBRONN, Germany, Sept. 11, 2013 /PRNewswire/ -- Atmel^® Corporation
(NASDAQ: ATML), a global leader in microcontroller and touch technology
solutions, today announced the availability of a new family of low-power,
high-performance RF receivers designed specifically for the automotive and
smart RF markets.


With the industry's lowest power consumption, high sensitivity and excellent
out-of-band blocking performance, the three new devices (ATA5781, ATA5782 and
ATA5783) are ideal for automotive applications including remote keyless entry
(RKE), passive entry go (PEG)/ passive entry passive start (PEPS), remote
start (RS) and tire pressure monitoring (TPMS) systems. This new RF family is
also a perfect fit for a broad range of smart RF applications including remote
control systems such as garage door openers or telemetering applications.

The ATA5781, ATA5782, and ATA5783 family consumes only 9.8mA typical in
receive mode whereas the power consumption of competing devices is 12mA
typical. This reduced drain will leave more charge in the battery leading to
longer standby times when the car is stopped with the receiver enabled. The
parts feature an excellent sensitivity of -122.5dBm typical when programming
the IFBW (intermediate frequency bandwidth) to its lowest value of 25kHz. This
enables an extended RF communication range.

RF blocking performance rates the receiver's immunity to disturbers. These
disturbers are frequently present in the field. The outstanding blocking
performance of the ATA578x family significantly reduces power-robbing false
wake-ups. It also prevents RF range reduction and communication failure caused
by RF disturbers.

The new devices provide dual paths for simultaneous FSK and ASK reception and
superior flexibility by combining RF functionality, an advanced state machine,
and an Atmel AVR^® microcontroller core. Customers can configure up to five
services including RKE, RS, PEPS, and TPMS on the fly in idle mode via SPI
(serial peripheral interface). This makes end-of-line programming at the
customer production site no longer necessary and thus helps to save production
time and cost. The dual path reception and flexibility lets customers adapt
receiver behavior to individual applications. Customers can optimize power
consumption since they can adapt the polling scheme as needed. If
customer-specific adaptations are required, designers can add the existing
firmware via Flash (ATA5782) or user ROM (ATA5783).

The new RF receiver family includes:

  oATA5781: Ready-to-use RF receiver IC with integrated firmware
  oATA5782: Firmware is included in read-only memory (ROM). Additional Flash
    option for application-specific software needs.
  oATA5783: Cost-optimized version of ATA5782, where customer software is ROM

Atmel's RF portfolio includes receiver and transceiver devices (ATA5831/32/33)
that are pin-, function- and RF-matching-compatible to ensure maximum
development re-use for one- and two-way systems. This minimizes the system
designers' design efforts. To help further reduce development and production
complexity and to accelerate time to market, end-application engineers can use
the same printed circuit board design for uni-directional and bi-directional
car access systems.

Samples of Atmel's ATA5781, ATA5782 and ATA5783 in 5mm x 5mm small QFN32
packages are available now starting at $1.90 USD (50K pcs). Car access kits
(ATAK51003-V1) to support design-in and shorten time-to-market are available.
