MCP2561-E/MF

Drivers, Receivers, Transceivers Overview

The MCP2561-E/MF is a high-speed CAN transceiver manufactured by Microchip Technology, designed to interface between a CAN protocol controller and the physical two-wire bus. It supports data rates up to 1 Mb/s and complies with ISO-11898-2 and ISO-11898-5 standards. The device operates within an extended temperature range of -40°C to +125°C and requires a VDD supply voltage between 4.5V and 5.5V. It features a SPLIT pin for common mode stabilization in biased split termination schemes and includes protection against short circuits, high-voltage transients, and thermal overload.

Drivers, Receivers, Transceivers Feature Summary

• Supports high-speed operation up to 1 Mb/s compliant with ISO-11898-2 and ISO-11898-5 standards
• Includes a dedicated SPLIT output pin to stabilize common mode voltage in biased split termination configurations
• Provides robust protection against positive and negative battery voltage short-circuits and high-voltage transients
• Features automatic thermal shutdown to disable output drivers when junction temperature exceeds nominal limits

Drivers, Receivers, Transceivers Applications

• Automotive electronic control units (ECUs) requiring fault-tolerant communication
• Industrial systems operating in harsh environments with high electromagnetic noise
• Network nodes requiring low standby current consumption for power management

Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix 'MF' corresponds to the SOIC-8L package type as specified in the manufacturer's product identification system. Confirm the 'E' designation indicates the Extended temperature range (-40°C to +125°C). Ensure compatibility with the required PCB footprint for the 8-lead small outline integrated circuit package before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select the MCP2561-E/MF when a SPLIT pin is required for common mode stabilization rather than a separate VIO supply pin. This model is suitable for systems where the digital I/O supply is internally connected to VDD. Compare against the MCP2562 variant if interfacing with microcontrollers using lower voltage logic levels via a dedicated VIO pin is necessary.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MCP2561/2 family of second-generation high-speed CAN transceivers from Microchip Technology. The family includes variants with either a SPLIT pin (MCP2561) or a VIO pin (MCP2562). These devices are engineered to meet stringent automotive design requirements, including EMC and ESD performance, while providing a reliable interface for CAN protocol controllers.

Drivers, Receivers, Transceivers Replacement Considerations

The MCP2562-E/MF serves as a functional alternative within the same family, differing primarily by the inclusion of a VIO pin instead of the SPLIT pin. Verify that the specific application does not require the common mode stabilization provided by the SPLIT pin before substituting.
