MCP2515-E/MLVAO

Controllers Overview

The MCP2515-E/MLVAO is a stand-alone CAN controller implementing the CAN V2.0B specification at data rates up to 1 Mb/s. It supports standard and extended data frames with 0-8 byte payloads, utilizing three transmit buffers and two receive buffers. The device interfaces with microcontrollers via a high-speed SPI bus operating at 10 MHz in modes 0,0 and 1,1. Powered by low-power CMOS technology, it operates within a voltage range of 2.7V to 5.5V, drawing 5 mA typically in active mode and 1 µA in sleep mode. The component is housed in a 20-lead QFN package and is rated for an extended industrial temperature range from -40°C to +125°C.

Controllers Feature Summary

• Implements CAN V2.0B protocol with support for standard and extended data and remote frames.
• Features six 29-bit acceptance filters and two masks for efficient message filtering to reduce host MCU overhead.
• Includes a high-speed SPI interface compatible with modes 0,0 and 1,1 for reliable communication with host controllers.
• Provides programmable clock output and Start-of-Frame monitoring capabilities for system diagnostics.

Controllers Applications

• Automotive electronic control units requiring robust CAN communication.
• Industrial automation systems utilizing Controller Area Network protocols.
• Embedded sensor networks needing stand-alone CAN interfacing.

Controllers Procurement Notes

Verify the specific suffix 'VAO' against official Microchip documentation to confirm its exact meaning regarding automotive qualification or variant status. Ensure the ordering information matches the required extended temperature grade and QFN package type. Cross-reference the datasheet revision to guarantee compatibility with current manufacturing specifications.

Controllers Selection Notes

Select this component when a stand-alone CAN controller is required for applications supporting CAN V2.0B standards. It is suitable for designs needing flexible message filtering and prioritization without integrating a full transceiver. Consider the 20-lead QFN package constraints and thermal management requirements for the exposed pad during PCB layout.

Controllers Part Context

This part belongs to the MCP2515 family of stand-alone CAN controllers manufactured by Microchip Technology. The series provides various package options including PDIP, SOIC, TSSOP, and QFN to accommodate different board space and thermal needs. The device simplifies CAN bus integration by handling protocol processing independently of the host microcontroller.

Controllers Replacement Considerations

Check for alternative packages such as MCP2515-I/ML or MCP2515-E/P if pinout compatibility allows. Verify that any substitute maintains the same extended temperature rating and SPI interface timing characteristics to ensure seamless integration into existing designs.
