HEILBRONN, Germany, September 10 /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.
