MCP2510T-I/ST

Controllers Overview

The MCP2510T-I/ST is a stand-alone CAN protocol controller implementing CAN V2.0A and V2.0B specifications. It supports data rates up to 1 Mb/s with message lengths of 0 to 8 bytes, handling standard and extended data frames as well as remote frames. The device features three transmit buffers and two receive buffers, six acceptance filters, and two masks to reduce microcontroller overhead. Communication with the host MCU occurs via a high-speed SPI interface operating at up to 5 MHz. It operates within a supply voltage range of 3.0V to 5.5V and functions in industrial temperatures from -40°C to +85°C.

Controllers Feature Summary

• Implements full CAN V2.0A and V2.0B protocols with programmable bit rates up to 1 Mb/s.
• Includes three transmit buffers with prioritization and abort capabilities alongside two receive buffers.
• Features six full acceptance filters and two masks for efficient message filtering.
• Interfaces with microcontrollers via a standard SPI bus supporting modes 0,0 and 1,1.

Controllers Applications

• Industrial automation systems requiring robust CAN communication.
• Automotive electronic control units and sensor networks.
• Building automation and smart grid infrastructure.

Controllers Procurement Notes

Verify the specific suffix 'I/ST' corresponds to the Industrial temperature range (-40°C to +85°C) and Tape & Reel packaging format. Confirm that the ordering part number matches the exact datasheet revision required for your design. Ensure compatibility with the host system's SPI voltage levels and pin configuration before finalizing procurement.

Controllers Selection Notes

Select this component when a dedicated hardware solution for CAN protocol processing is required to offload the main CPU. It is suitable for designs needing multiple transmit buffers with priority management and extensive hardware filtering. Consider the TSSOP-20 package constraints and verify that the host MCU supports the necessary SPI clock speeds and interrupt configurations.

Controllers Part Context

This component belongs to the MCP2510 family of standalone CAN controllers manufactured by Microchip Technology. It serves as a bridge between microcontrollers and the CAN bus, handling protocol encoding and decoding. The 'T' indicates tape and reel packaging, while 'I' denotes the industrial temperature grade, distinguishing it from extended temperature variants.

Controllers Replacement Considerations

The MCP2515 is a compatible alternative offering similar functionality but limited to 1 Mbps data rates. Verify that the replacement supports the required CAN V2.0B implementation and check for pinout compatibility if substituting directly on existing PCB layouts.
