Suitable for up to 5 Mbit/s

Atmel has launched a series of high-speed transceiver chips for CAN FD networks, which provides optionally low-power capability compliant with ISO 11898-5. The temperature range is -40 °C to +150 °C.

THE ATA6560 AND ATA6561 TRANSCEIVER CHIPS can be connected to MCUs with on-chip CAN modules. The ATA6561 offers a direct interface to MCUs with 3-V to 5-V supply voltages. Various operating modes together with the dedicated fail-safe features make the chips suitable for CAN FD networks, especially in CAN nodes requiring a low-power mode. The products are available in SO8 and DFN8 packages with wet-able flanks for automated optical solder inspection.

“Our new family of CAN transceivers enables our OEMs to bring improved connectivity with higher speed in their automobile with overall lower power,” explained Claus Mochel, Atmel Marketing Director for automotive high voltage products. “We are continuing to expand our automotive product portfolio to give our customers the right mix of products to help shorten their design cycle and bring next-generation designs faster to market.”

The transceiver chips qualified for data-phase bit-rates of up to 5 Mbit/s can detect under-voltages on the VCC and VIO pins. They are also protected against short-circuits (CANH-to-CANL) and over-temperature. Additionally, they feature a dominant time-out function. The ATA6560 provides a silent mode (receive only). Both CAN transceivers are available in mass production. Pricing starts at US$ 0,48 each in 10 000-piece quantities.
