MCP2515T-I/SO

Controllers Overview

The MCP2515T-I/SO is a stand-alone CAN controller implementing the CAN V2.0B specification at data rates up to 1 Mb/s. It interfaces with microcontrollers via an industry-standard SPI protocol block supporting modes 0,0 and 1,1 with speeds up to 10 MHz. The device features three transmit buffers with prioritization and abort capabilities, alongside two receive buffers equipped with six 29-bit acceptance filters and two masks for message filtering. Operating on low-power CMOS technology, it functions within a supply voltage range of 2.7V to 5.5V, drawing typical active current of 5 mA and standby current of 1 μA in sleep mode. It supports standard and extended data frames as well as remote frames.

Controllers Applications

• Automotive electronic systems requiring CAN bus connectivity
• Industrial control networks and automation nodes
• Embedded sensor networks and IoT edge devices

Controllers Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct manufacturer channels. Confirm the specific suffix 'I/SO' matches industrial temperature range (-40°C to +85°C) and SOIC-18 package requirements. Request official datasheet DS20001801J and RoHS compliance documentation prior to finalizing orders to ensure alignment with project specifications.

Controllers Selection Notes

Select this component when a stand-alone CAN controller is required to offload protocol processing from the host MCU. Ensure the design includes an external CAN transceiver, as the MCP2515 handles only the protocol layer. Verify that the host microcontroller supports SPI communication and can accommodate the necessary interrupt and control pin connections defined in the pinout description.

Controllers Part Context

This part belongs to the MCP2515 series of stand-alone CAN controllers manufactured by Microchip Technology. It serves as a hardware implementation of the CAN 2.0B protocol stack, reducing software overhead on the main processor. The 'T' indicates tape and reel packaging, while 'I' denotes the industrial temperature grade and 'SO' specifies the 18-lead SOIC package type.

Controllers Replacement Considerations

The MCP2515T-I/ST (TSSOP-20) offers equivalent functionality in a different surface-mount package. Designers must verify pin compatibility and thermal management requirements when substituting packages. No other direct functional replacements are confirmed in the provided documentation.
