描述 Description

The Microchip ATA6566 is a high-speed CAN FD transceiver dedicated for the Japanese market. It provides an interface between a controller area network (CAN)protocol controller and the physical two-wire CAN bus. The transceiveris designed for high-speed (up to 2Mbit/s) CAN applications in theautomotive industry, providing differential transmit and receivecapability to (a microcontroller with) a CAN protocol controller. Itoffers improved electromagnetic compatibility (EMC) and electrostaticdischarge (ESD) performance, as well as features such as: Ideal passive behavior to the CAN bus when the supply voltage is off Direct interfacing to microcontrollers with supply voltages from 3V to 5VTwo operating modes (Standby and Normal Mode) together with the dedicated fail-safe features make the Atmel. ATA6566 an excellent choice for all types of high- speed CAN networks, especially in nodes requiring low-power mode with wake-up capability via the CAN bus.The ATA6566 is automotive Grade 0 qualified for an ambient temperature range from -40° to 150°C.To purchase the ATA6566 or obtain additional information, please contact any Microchip sales representative or authorized worldwide distributor.
