Chandler, Ariz. - Microchip Technology's newest standalone controller-area network (CAN) device now offers the option to address serial communications challenges. The MCP2515 gives designers a CAN solution that provides faster data throughput and efficient data byte filtering, the company said. It also generates start-of-frame output and uses an SPI interface, which enables an easy connection to virtually any microcontroller, according to Microchip.
The MCP2515 has a 40-MHz maximum clock input speed and a 10-MHz high-speed SPI interface. This faster throughput enables CAN messages to be processed and transferred to the host microcontroller much faster than the company's original standalone CAN solution, Microchip said.
The device also has the ability to filter messages based on the first two data bytes and the 11 identifier bits. This feature reduces the microcontroller overhead requirements needed to support high-layer protocols, like DeviceNet, that utilize data bytes in addition to identifier bits for determining whether CAN messages should be received and processed by certain nodes.
Designed for use in automotive, industrial, robotics, power supply, test and semiconductor equipment, the MCP2515 is available in the industrial temperature range in plastic dual in-line and small-outline IC packages. Pricing in 1,000-unit quantities is $1.72 each. In addition, Microchip is upgrading its MCP2510 CAN Developer's Kit (DV251001) to support the MCP2515. Samples and volume production are available now.
