MCHPMCP2561-E/SN
Overview
The MCP2561-E/SN is a high-speed CAN transceiver that provides the physical interface between a CAN protocol controller and the physical two-wire CAN bus. It is compliant with ISO-11898-2 and ISO-11898-5 standards, supporting data rates up to 1 Mb/s while maintaining low power consumption with a 5uA standby current. This variant features an integrated Vio pin for direct interfacing with low-voltage microcontrollers ranging from 1.8V to 5.5V.
Why Choose This Part
The MCP2561 provides excellent electromagnetic compatibility (EMC) and high electrostatic discharge (ESD) protection, reducing the need for external filtering. Its unique SPLIT pin helps stabilize common-mode levels in biased split termination schemes, while the Vio pin simplifies level-shifting for modern low-voltage MCUs.
Applications
Key Specifications
Getting Started
To evaluate this transceiver, engineers can use the CAN Bus Analyzer Tool (APGDT002) from Microchip or integrate the chip onto a breadboard using an 8-SOIC to DIP adapter. Ensure a 120-ohm termination resistor is present at both ends of the CAN bus and bypass the VDD and Vio pins with 0.1uF capacitors for optimal noise performance.
