Description
The MCP2557FD/8FD CAN transceiver family is
designed for high-speed CAN FD applications with up
to 8 Mbps communication speed. The maximum propagation
delay was improved to support longer bus
length.
The device meets automotive requirements for CAN
FD bit rates exceeding 2 Mbps, low quiescent current,
electromagnetic compatibility (EMC) and electrostatic
discharge (ESD).
