5/8/2003 - Atmel® Corporation (Nasdaq: ATML) announced the availability of a new high-speed CAN bus transceiver IC. The new ATA6660 is manufactured using Atmel's 0.8-micron BCDMOS process technology, which supports operation of up to 45 Volts and is optimized for applications in harsh environments. The ATA6660 is especially designed for high-speed differential mode data transmission such as AC motor drives in the large-scale equipment industry. As required for high-speed data transmission, the baud rate can be adjusted up to 1 Mbaud. Furthermore, the ATA6660 is fully compatible to the ISO 11898, the international standard for high-speed CAN data communication (CAN-C).
Atmel's objective is to provide various solutions to meet system designers' diverse needs. Atmel has introduced several bus interface ICs designed for dedicated applications in recent years. For automotive diagnostics, a K-line driver (U6812B) is available, for automotive comfort applications such as sunroof handling, seat memory etc., a LIN bus transceiver is in development and will be available end of 2003; and a low-speed CAN transceiver B10011S is designed for 24-V trailer/ truck applications.
"With this new transceiver, Atmel extends its CAN product portfolio and closes the gap between the bus line and the CAN controller", Torsten Mann, Marketing Director for Automotive and Control products at Atmel, explained. "The new ATA6660 is perfectly suited to operate with Atmel's innovative Flash C51 microcontroller family CANary(tm). System makers can now buy a complete chip set from Atmel. Various design tools and application support are available as highlighted in the latest Atmel CAN CD-ROM."
To minimize EMC problems, the ATA6660 incorporates a controlled slew rate that prevents unsymmetrical transients on the bus lines. The receiver's control feature helps to reduce RF interference, caused by signals on the two bus lines, to a minimum. In well-designed bus configurations this feature means filter design costs can be reduced drastically.
Furthermore, the ATA6660 provides several protection features such as overtemperature warning, full protection against short circuits and high-voltage bus line protection up to -/+ 40 V. The device also meets strict automotive qualification demands (protection against conducted interference, EMC and 8-kV ESD protection), and it can withstand transients according to ISO/TR 7637/1.
Samples of the new high-speed CAN transceiver IC ATA6660 in SO8 packages are available now. Pricing starts at US$ 0.65 (10 k).
