Atmel's UHF ASK/FSK Receiver ICs for TPMS and RKE Applications Provide Best Trade-off between High Integration, High Performance and Worldwide Frequency Coverage

Heilbronn, Germany (ots/PRNewswire) -

Atmel(R) Corporation (Nasdaq: ATML) announced today the
availability of the new ATA5723, ATA5724, and ATA5728 UHF ASK/FSK
receiver ICs, extending Atmel's existing broad portfolio of
automotive RF devices. These three new devices offer the best
compromise between high integration, outstanding performance, and
worldwide frequency coverage. These three new ICs are pin compatible,
which means they can be used, without board design changes, for all
standard automotive frequency ranges: 313 to 317 MHz (ATA5723), 432
to 436 MHz (ATA5724), and 868 to 870 MHz (ATA5728). The devices are
manufactured using Atmel's RF BiCMOS process. Housed in a small
footprint SSO20 package, they are a perfect fit for Remote Keyless
Entry (RKE) and Tire Pressure Monitoring System (TPMS) applications.

The ATA5723, ATA5724, and ATA5728 support the typically used
Manchester and Bi-phase coding signals. In addition, they provide a
logarithmic RSSI output, which enables customers to achieve good
resolution at low field strengths. The ICs' excellent receiving
selectivity is accomplished by an integrated image rejection mixer
with 30 dB rejection, -113 dBm sensitivity, and improved selectivity
due to the integrated IF filter, low-phase-noise VCO, PLL, and loop
filter.

The new receiver ICs need few external devices and no external
filters -- adding to their cost-efficiency. Ten passive components, a
crystal, and an RF antenna are all that is typically needed to create
a receiver board application. Additionally, due to the ICs' large
oscillation margin, designers can choose very low-cost crystals.

The ATA5723, ATA5724, and ATA5728 are based on Atmel's well-known
ATA5743, which has set a worldwide standard with its unique polling
mode functionality. As a result, the devices' polling features allows
the microcontroller to remain in standby mode, enabling very low
current consumption for complete applications. The active current
consumption is specified at about 8 mA in receiving mode. The
single-ended RF input allows easy adaptation of lambda/4 or printed
loop antennas and leads to relaxed tolerance requirements for RF
matching components.

Availability and Pricing

Samples of the ATA5723/ATA5724/ATA5728 are now available in SSO20
packages. Pricing starts at US $1.40 (for 10k piece quantities).
Customers of the three new receivers ICs can use the software
currently available for the ATA5743. Evaluation boards, ATA5723-DK,
ATA5724-DK and ATA5728-DK, to support the system designer are also
available at a cost of US $99.
