MCP25612FD Dual CAN Flexible Data-Rate Transceiver Temperature Ranges: Features - Extended (E): -40C to +125C Supports both classic CAN 2.0 and CAN FD - High (H): -40C to +150C physical layer requirements Optimized for CAN FD (Flexible Data-Rate) at Description 2, 5 and 8 Mbps Operation: The MCP25612FD is a second generation, dual CAN - Maximum Propagation Delay: 120 ns FD transceiver from Microchip Technology Inc. It offers - Loop Delay Symmetry: -10%/+10% (2 Mbps) all of the features from two fully independent Implements ISO-11898-2 and ISO-11898-5 MCP2561FD CAN transceivers, except for the SPLIT Standard Physical Layer Requirements pin. It ensures Loop Delay Symmetry in order to support Very Low Standby Current (5 A per transceiver, the higher data rates required for CAN FD. The maxi- typical) mum propagation delay is improved to support a longer Two Fully Independent V and V Pins per CAN DDX SSX bus length. FD Transceiver for Added Flexibility and Reliability: - Optimal for redundant CAN networks The device meets the automotive requirements for CAN FD bit rates, low quiescent current, robust Compatible to 5V MCUs Electromagnetic Compatibility (EMC) and Electrostatic Functional Behavior Predictable Under All Supply Discharge (ESD). Conditions: - Device is in Unpowered mode if V drops DDX below undervoltage level Package Types - An unpowered node or brown-out event will MCP25612FD not load the CAN bus SOIC Detection of Ground Fault: - Permanent dominant detection on T T 1 14 STBY1 XDX XD1 - Permanent dominant detection on bus V 2 13 CANH1 SS1 Power-on Reset and Undervoltage Lock-out on V CANL1 3 12 DD1 V Pin DDX R 4 11 STBY2 Protection against Damage due to Short-Circuit XD1 Conditions (positive or negative battery voltage) T 5 10 CANH2 XD2 Protection against High-Voltage Transients in V 6 9 CANL2 SS2 Automotive Environments V 7 8 R DD2 XD2 Automatic Thermal Shutdown Protection Suitable for 12V and 24V Systems Meets or exceeds Stringent Automotive Design Requirements, including Hardware Requirements Typical Applications for LIN, CAN and FlexRay Interfaces in Automotive Automotive Applications, Version 1.3, May 2012: Powertrain - Conducted emissions 2 Mbps with Common-Mode Choke (CMC) Body Control - Direct Power Injection (DPI) 2 Mbps with CMC Gateway Meets SAE J2962/2 Communication Chassis and Safety Transceivers Qualification Requirements CAN: Infotainment - Passes radiated emissions at 2 Mbps without Industrial a CMC Factory Automation High Noise Immunity due to Differential Bus Implementation Gateway High ESD Protection on CANHx and CANLx, Server Backplanes Meets IEC61000-4-2, up to 6 kV Elevators Available in 14-Lead SOIC Robotics 2015 Microchip Technology Inc.
