MCP25625-E/SS

Drivers, Receivers, Transceivers Overview

The MCP25625-E/SS is a standalone CAN 2.0B controller with an integrated high-speed transceiver and SPI interface, housed in a 28-lead SSOP package. It supports data rates up to 1 Mb/s and operates with a digital supply voltage (VDD/VIO) of 2.7V to 5.5V, while the analog transceiver supply (VDDA) requires 4.5V to 5.5V. The device features three transmit buffers with prioritization, two receive buffers, six acceptance filters, and two masks. It includes low standby current of 10 µA typical, ESD protection up to ±8 kV on CANH/CANL, and operates within an extended temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates a CAN 2.0B controller and high-speed transceiver into a single small-footprint solution.
• Interfaces directly with microcontrollers operating at 2.7V to 5.5V without external level shifters.
• Provides hardware-based message prioritization, abort capabilities, and configurable request-to-send pins.
• Includes robust protection features such as thermal shutdown, ground fault detection, and unpowered bus disconnection.

Drivers, Receivers, Transceivers Applications

• Automotive electronic control units requiring CAN 2.0B compliance.
• Industrial automation systems utilizing CAN bus communication.
• Embedded devices needing a compact, cost-effective CAN node with SPI connectivity.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E/SS' corresponds to the Extended temperature range (-40°C to +125°C) and SSOP-28L package. Confirm that the VDDA supply requirement of 4.5V to 5.5V aligns with the system design, as it differs from the digital logic supply range. Ensure compatibility with SPI modes 0,0 and 1,1 for the host microcontroller interface.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a combined controller and transceiver is preferred over discrete solutions to reduce board space. Ensure the application can provide a dedicated 5V rail for VDDA if the digital supply is lower than 4.5V. Consider the SSOP-28L package constraints regarding thermal dissipation and pin pitch during PCB layout planning.

Drivers, Receivers, Transceivers Part Context

The MCP25625 belongs to the MCP2562 family of CAN controllers with integrated transceivers. It serves as an evolution to separate controller and transceiver designs, simplifying the hardware architecture for CAN-enabled applications. The 'E' designation indicates the extended industrial/automotive temperature grade, distinguishing it from commercial variants.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements within the same family include the MCP25625T-E/SS (tape and reel packaging). For discrete alternatives, combinations such as the MCP2515 controller paired with an MCP2562 transceiver may be used, though this increases component count and board area.
