MCP2515T-I/ST

The MCP2515T-I/ST is a stand-alone controller area network (CAN) Controller that implements the CAN specification, version 2.0B. It is capable of transmitting and receiving both standard and extended data and remote frames. The MCP2515 has two acceptance masks and six acceptance filters that are used to filter out unwanted messages, thereby reducing the host MCU's overhead. The MCP2515 interfaces with microcontrollers (MCUs) via an industry standard Serial Peripheral Interface (SPI). The device consists of three main blocks, that is CAN module, which includes the CAN protocol engine, masks, filters, transmit and receive buffers. The control logic and registers that are used to configure the device and its operation and the SPI protocol block.

• Simple SPI interface to any MCU
• One-shot mode ensures message transmission is attempted only once
• Start-of-frame (SOF) output
• Low-power CMOS technology
• Implements CAN V2.0B at 1Mb/s
• Receive buffers, masks and filters
• Data byte filtering on the first two data bytes
• Three transmit buffers with prioritization and abort features
• One-shot mode ensures message transmission is attempted only one time
• Clock out pin with programmable prescaler
