MCHPMCP2515-I/ST
Overview
The MCP2515-I/ST is a stand-alone CAN 2.0B controller that interfaces with microcontrollers via a standard Serial Peripheral Interface (SPI). It offloads the complex timing and message management requirements of the CAN protocol from the host MCU, enabling CAN functionality on processors that lack an integrated CAN peripheral.
Why Choose This Part
This controller supports both standard and extended data frames and includes three transmit buffers and two receive buffers to reduce host MCU overhead. It operates over a wide 2.7V to 5.5V range and features a low-power standby mode with a typical current consumption of 1uA.
Applications
Key Specifications
Getting Started
To evaluate the chip, engineers often use the MCP2515 CAN Bus Monitor Demo Board or connect the 20-TSSOP package to an MCU via the 10MHz SPI interface. Extensive software libraries are available for Arduino and PIC platforms to simplify register configuration and message filtering.
