Atmel Unveils Industry's First Off-the-Shelf LF Antenna Driver IC for Passive Entry Go/Passive Go Systems

Heilbronn, Germany (ots/PRNewswire) -

Atmel(R) Corporation (Nasdaq: ATML) announced today the
availability of the new LF coil driver IC ATA5279 designed for
Passive Entry Go (PEG) and Passive Go (PG) hands-free car access
systems. This is industry's first and only off-the-shelf antenna
driver IC. Compared to today's discrete or ASIC solutions, this IC
enables much smaller and considerably less expensive designs, while
at the same time offering increased reliability.

The ATA5279 is capable of sequentially driving up to six separate
125 kHz low-frequency antennas (i.e., coils) to provide a wake-up and
initialization channel to the key fob. Superior EMC behavior is
guaranteed by the sinusoidal-like output signals at all six channels,
which helps avoid interferences with other electronic car components.
In addition, the IC has twenty individually selectable coil currents
steps at each channel to enable precise field-strength measurements.

With its superior diagnostics, the ATA5279 monitors all six
connected antennas and stores any possible failures in the internal
register. As a result of this, the ATA5279 protects the system and
itself from any damage, reducing service work at the OEM's assembly
line and their authorized repair shops.

The ATA5279 is manufactured using Atmel's own BCD-on-SOI
(SMART-I.S.(R)) technology, which, amongst others, results in a very
low power-down current consumption of 6 uA to 8 uA, thus minimizing
battery usage. The ATA5279 also meets strict automotive qualification
demands by withstanding load dump and jump start scenarios as
specified by ISO/TR 7637/1. The new antenna driver IC ATA5279 is, of
course, fully protected against electrical and thermal overloads.

Outstanding EMC behavior, superior diagnostics and the ability to
drive six separate low-frequency antennas make the ATA5279 an ideal
fit for all LF 125-kHz-based Passive Entry Go (PEG) and Passive Go
(PG) hands-free car access systems.

Availability and Pricing

Samples of the ATA5279 are now available in RoHS-compliant QFN48
packages measuring only 7 mm x 7 mm. Pricing starts at US $3.31 (for
10k piece quantities). To support the system designer, an LF trigger
board (ATAB5279), an AVR(R)-based main board (ATAB-LFMB-79), a 3D LF
receiver board (ATAB5282), and an additional LF antenna module
(ATAB-LFTX-Mod1) are also available.
