MCP2515-E/SO

Controllers Overview

The MCP2515-E/SO is a stand-alone CAN controller implementing the CAN V2.0B specification, designed for extended industrial temperature ranges (-40°C to +125°C). It interfaces with microcontrollers via a high-speed SPI bus operating at up to 10 MHz in modes 0,0 and 1,1. The device supports data rates up to 1 Mb/s and handles standard/extended data frames and remote frames with 0 to 8-byte data fields. Electrical characteristics include a supply voltage range of 2.7V to 5.5V, typical active current of 5 mA, and standby current of 1 µA in sleep mode. It features three transmit buffers and two receive buffers.

Controllers Feature Summary

• Implements CAN V2.0B protocol with support for standard and extended data frames as well as remote frames.
• Integrates hardware message filtering using six acceptance filters and two masks to reduce host MCU overhead.
• Provides three prioritized transmit buffers with abort capabilities and one-shot transmission mode.
• Features a low-power CMOS design with configurable interrupt outputs and request-to-send input pins.

Controllers Applications

• Automotive electronic systems requiring robust Controller Area Network communication.
• Industrial control environments utilizing CAN bus protocols.
• Medical equipment integrating sensor data via CAN interfaces.

Controllers Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and '/SO' indicates the 18-lead SOIC package. Confirm the manufacturer is Microchip Technology Inc. Ensure the component matches the specific datasheet revision DS20001801J for accurate electrical parameters and pinout definitions before integration.

Controllers Selection Notes

Select this component when an independent CAN controller is required to interface with a host MCU via SPI. The extended temperature grade is necessary for harsh automotive or outdoor industrial applications. Consider the availability of external crystal oscillators for clock generation and the need for a separate CAN transceiver to connect to the physical bus layer.

Controllers Part Context

This part belongs to the MCP2515 family of stand-alone CAN controllers produced by Microchip Technology. It serves as a successor to earlier models like the MCP2510, offering enhanced performance and bug fixes while maintaining compatibility. The '-E' designation specifically denotes the extended temperature variant suitable for demanding operational environments compared to the industrial grade.

Controllers Replacement Considerations

The MCP2515-ESO is a lead-free version of the same component. Other variants within the family include the MCP2515-I/SO for industrial temperatures and different package options such as TSSOP or QFN. Verify pinout compatibility and temperature specifications when substituting.
