Overview
The MCP2515-I/ST, manufactured by Microchip Technology, is a stand-alone Controller Area Network (CAN) controller that implements the CAN specification, Version 2.0B. This component interfaces with microcontrollers (MCUs) via an industry-standard Serial Peripheral Interface (SPI). It is designed to operate within a supply voltage range of 2.7 to 5.5 volts and is encapsulated in a TSSOP-20 package, which is RoHS compliant. The MCP2515-I/ST is particularly notable for its role in managing CAN network communications, especially in high-speed automotive and industrial applications.
