MCP2515 — Datasheet Summary, Specs & Alternatives

01 — Overview

This Microchip datasheet covers the MCP2515, a standalone CAN V2.0B controller for 1Mb/s communication. It handles standard and extended frames with hardware filtering to reduce host MCU overhead. Key parameters include a supply voltage of 2.7V-5.5V, typical active current of 5mA, and standby current of 1µA. The device features two receive buffers, three prioritized transmit buffers, and a high-speed SPI interface up to 10MHz. It supports industrial and extended temperature ranges from -40°C to +125°C.
