MCP2515T-E/ML

Controllers Overview

The MCP2515T-E/ML is a stand-alone CAN controller implementing the CAN V2.0B specification at speeds up to 1 Mb/s. It interfaces with microcontrollers via a high-speed SPI bus operating at 10 MHz in modes 0,0 and 1,1. The device features three transmit buffers and two receive buffers, supported by six 29-bit acceptance filters and two masks for message filtering. Operating voltage ranges from 2.7V to 5.5V, with typical active current of 5 mA and standby current of 1 µA. It supports industrial (-40°C to +85°C) and extended (-40°C to +125°C) temperature ranges.

Controllers Feature Summary

• Implements CAN V2.0B protocol supporting standard and extended data frames as well as remote frames.
• Includes three transmit buffers with prioritization and abort capabilities alongside two receive buffers.
• Features a high-speed SPI interface compatible with modes 0,0 and 1,1 for MCU communication.
• Provides programmable clock output and Start-of-Frame signal monitoring for diagnostic applications.

Controllers Applications

• Automotive electronic systems requiring robust CAN communication
• Industrial control networks utilizing CAN bus protocols
• Embedded sensor nodes interfacing with host microcontrollers

Controllers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration when sourcing components. Confirm that the 'E' designation aligns with the required extended temperature range specifications for your application environment. Ensure compatibility with the 20-lead QFN package type during mechanical design integration.

Controllers Selection Notes

Select this component when a dedicated hardware solution for CAN protocol handling is required to reduce MCU load. Consider the 20-lead QFN package for space-constrained designs. Verify that the external physical layer transceiver matches the voltage levels and speed requirements of the target network.

Controllers Part Context

This part belongs to the MCP2515 family of stand-alone CAN controllers manufactured by Microchip Technology. It serves as a bridge between SPI-based microcontrollers and CAN bus networks, offloading complex protocol tasks such as bit timing, error handling, and frame filtering from the main processor.

Controllers Replacement Considerations

The MCP2515T-E/ML is functionally pin-compatible with the MCP2510. Designers upgrading from older generations should verify register mapping consistency. No other direct substitutes are confirmed in official documentation.
