Atmel Unveils Stand-alone LIN2.0 Transceiver IC with Industry's Best EMC Performance

    Heilbronn, Germany (ots/PRNewswire) -

    Atmel(R) Corporation (Nasdaq: ATML), a global leader in the development and fabrication of advanced semiconductor solutions, announced today the availability of its ATA6662 stand-alone LIN bus transceiver IC with the industry's best EMC performance (EMC test and conformance test LIN2.0, Europe, and SAE J2602-2, US). Thanks to Atmel's high-voltage BCD-on-SOI (SMARTIS(TM)) process, the new ATA6662 sets the benchmark in EMI performance for reduced RF interference. The device's excellent ESD protection (exceeding 6 kV) is beneficial for designing robust electronic units for the harsh automotive environment. This includes automotive comfort applications such as door modules, power seat controls, intelligent sensors, and other body electronic applications where low-speed data communication is sufficient and low cost is important.

    The ATA6662 complies with the LIN2.0 standard and can handle supply voltages of up to 40V. The fully-integrated LIN transceiver interfaces the LIN protocol handler (i.e., the local microcontroller) and the LIN bus. Improved slope control at the LIN bus ensures secure data communication of up to 20 kBaud using an RC oscillator for the protocol handling. The ATA6662's sleep mode minimizes current consumption to typically 10 microampere.

    To eliminate EMI problems, the ATA6662 incorporates a controlled slew rate. The receiver's input filter helps minimize RF interference caused by signals on the bus line. Compared to standard BCDMOS bulk technology, Atmel's SMARTIS process uses an SOI (silicon-on-insulator) substrate. This results in an extremely low leakage current, with a significant reduction in crosstalk between analog and digital circuits on the same die, as well as latch-up-free operation at high temperatures. Lower parasitic effects give added value for EMC performance.

    Furthermore, the ATA6662 provides several protection features such as over-temperature shutdown, full protection against short circuits, and high-voltage-bus-line protection up to 40V. The ATA6662 is fully compatible with 3.3V and 5V devices and includes a dominant time-out function on the TxD pin to prevent the bus line from being driven permanently in a dominant state. A wake-up source recognition indicates, on the TxD and RxD pins, which wake-up has occurred -- the local via pin WAKE-UP or the remote wake-up via the LIN bus line. Depending on the recognized wake-up source, the microcontroller selects the appropriate routines. The device also meets strict automotive qualification demands and can withstand transients according to ISO/TR 7637/1.

    Pricing and Availability

    Samples of the new LIN transceiver IC ATA6662 in SO8 packages are available now. Pricing starts at US$ 0.45 for 10k units.
