Microchip MCP2515-I/SO CAN Controller, SPI, SMD, SOIC18

The Microchip MCP2515-I/SO is a stand-alone Controller Area Network (CAN) controller designed for robust data communication in demanding electronic applications. Capable of transmitting and receiving both standard and extended data and remote frames, it significantly reduces the processing load on the host microcontroller by handling complex network protocols independently.

A key feature is its sophisticated message filtering system, comprising two acceptance masks and six acceptance filters to efficiently screen out unwanted messages. This ensures that only relevant data reaches the host MCU, optimising system performance and responsiveness.

Key Features & Specifications

• Interface: Connects to microcontrollers via a high-speed Serial Peripheral Interface (SPI) running at up to 10 MHz.
• Data Handling: Supports a flexible data field length of 0–8 bytes and manages standard and extended data and remote frames.
• Buffering: Includes two receive buffers with prioritised message storage and three transmit buffers with prioritisation and abort features for reliable data flow control.
• Operational Modes: Features a one-shot mode to ensure a message transmission is attempted only once, and a clock-out pin with a programmable prescaler that can serve as a clock source for other devices.
• Monitoring & Control: Provides a start-of-frame (SOF) signal for network monitoring and an interrupt output pin with selectable enables for efficient event handling.
• Efficiency: Built with low-power CMOS technology, making it suitable for power-sensitive applications.

With its comprehensive feature set and reliable performance across a wide operating temperature range, the MCP2515-I/SO is an essential component for building sophisticated, network-connected embedded systems.
