MCP2515-I/ML

Controllers Overview

The MCP2515-I/ML is a stand-alone CAN controller implementing the CAN V2.0B specification with support for data rates 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, along with 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. The industrial temperature grade (-40°C to +85°C) component utilizes a 20-lead QFN package.

Controllers Feature Summary

• Implements CAN V2.0B protocol supporting standard and extended data frames as well as remote frames.
• Integrates hardware message filtering using six 29-bit filters and two 29-bit masks to reduce host MCU overhead.
• Provides three prioritized transmit buffers with abort capabilities and two receive buffers with prioritized storage.
• Features a programmable clock output pin that can serve as a clock source or monitor Start-of-Frame signals.

Controllers Applications

• Automotive electronic systems requiring CAN V2.0B compliance
• Industrial control networks utilizing serial communication controllers
• Medical equipment integrating Controller Area Network protocols

Controllers Procurement Notes

Verify the specific suffix 'I/ML' corresponds to the Industrial temperature range and QFN package configuration required for your design. Confirm RoHS compliance status through official Microchip documentation prior to ordering. Ensure the selected variant matches the thermal pad requirements for the 20-lead QFN footprint.

Controllers Selection Notes

Select this component when a stand-alone CAN controller is needed to offload protocol processing from the main microcontroller. The MCP2515-I/ML is suitable for applications requiring robust message filtering and low-power sleep modes. Consider the 20-lead QFN package constraints and ensure adequate thermal management for the exposed pad if operating near maximum temperature limits.

Controllers Part Context

The MCP2515 serves as a stand-alone solution for Controller Area Network implementations, simplifying integration with various microcontrollers via SPI. It replaces complex discrete logic solutions by providing integrated protocol handling, buffering, and filtering. This component is part of Microchip's broader family of CAN interface devices designed for reliable serial communication in noisy environments.

Controllers Replacement Considerations

The MCP2510 is a compatible predecessor with pin and functional compatibility, though it lacks some performance enhancements found in the MCP2515. Verify register compatibility and feature differences such as data byte filtering when migrating between these variants.
