The MCP2515-I/ST is a second generation stand alone CAN (Controller Area Network) controller with SPI Interface in 20 pin TSSOP package. This CAN controller implements CAN specification version 2.0B. It is capable of transmitting and receiving both standard, extended data and remote frames. It has two acceptance masks and six acceptance filters for filter out unwanted messages thereby reducing host MCU's overhead. The MCP2515 interfaces with microcontrollers (MCUs) via an industry standard SPI interface. This CAN controller is pin and function compatible with MCP2510 and also includes upgraded features like faster throughput, data byte filtering and support for time triggered protocols.
Implements CAN V2.0B at 1Mbps
Operating voltage range from 2.7V to 5.5V
Low power CMOS technology
Two receive buffers with prioritized message storage, six 29bit filters, two 29bit masks
Data byte filtering on first two data bytes (applies to standard data frames)
Three transmit buffers with prioritization and abort features
High speed SPI interface (10MHz)
One shot mode ensures message transmission is attempted only one time
