| Atmel Targets Low-frequency RFID Applications with Introduction of
Heilbronn, Germany - Atmel® Corporation announced today the availability of
its new LF RFID IC ATA5558 with integrated anti-collision functionality. The ATA5558 is a contactless Read/Write
(R/W) RFID device for multi- or single-tag applications in the low frequency (LF) range, such as animal
identification, laundry management, industrial automation, item tagging, and ISO cards. The ATA5558 extends Atmel's
broad RFID product portfolio ranging from standard read-only up to high-security crypto devices.
The need for
RFID is growing substantially due to its increased performance and enhanced functionality. Compared with bar codes,
RFID provides extended read/write distances, line-of-sight is not necessary, and data can be changed whenever
needed. Low-frequency RFID provides advantages such as insensitivity in rugged environments (e.g., against water,
dirt and dust).
The ATA5558 provides an integrated anti-collision feature, thus enabling reading
more than one tag simultaneously. Standard tags interfere with each other as they transmit at the same time, whereas
the anti-collision functionality ensures that one tag talks after the other. The ATA5558's multi-tag identification
is based on a deterministic anti-collision algorithm which requires unique tag identification information (Tag
Furthermore, the ATA5558 features 1-kbit memory, allowing storage of larger amounts of
data, and password protection that prevents unauthorized read and/or write access to protected user definable memory
pages for increased safety. Specific programming (public mode) makes sure that the ATA5558 can also be used as a
standard Read/Write device when the anti-collision function is not needed. The integrated capacitor enables easy
system design since a coil is the only external part needed.
Atmel, a pioneer in the RFID area
and member of EPCglobal, provided the industry's first read-only RFID ICs in the late 1980's. Since 1995, Atmel
has also been offering the world's most flexible read/write RFID ICs. Today, Atmel is a key player in
low-frequency-based 125 kHz RFID ICs for access control systems. The portfolio also includes ICs addressing the
13.56 MHz, UHF and Microwave frequency ranges.
Samples of the new LF RFID IC ATA5558 as die in
tray packages are available now. Pricing starts at US$ 0.98 (10 k).
