Complete CAN Solutions for Diverse Embedded Applications CAN Solutions
Microchip Brings CAN to Your Embedded Design Bring communication and connectivity in your embedded design to the next level with Controller Area Network (CAN) bus solutions from Microchip Technology. Originally created for automotive applications, the CAN serial bus protocol is a high-speed, reliable communication protocol for applications requiring robust communications at bit rates reaching 1 Mbps. Incorporating the CAN protocol into your design is a low-cost, reliable way to function in a difficult electrical environment with a high degree of real-time capability. Microchip offers a complete line of products to meet the needs of high-performance embedded applications using the CAN protocol, including 8- and 16-bit microcontrollers with integrated CAN, stand-alone CAN controllers, CAN I/O expanders, and CAN transceivers. With easy-to-use development systems and application notes, Microchip provides a total CAN solution that enables low-risk product development, lower total system cost, and faster time to market for your high performance embedded design. Target Applications CAN is being designed into a wide range of applications that use command and control networks. Some of these applications include: Industrial control Maritime electronics Avionics/aerospace electronics UPS (uninterruptable power supply) Heavy machinery and earth moving equipment Factory automation Medical equipment Elevator control Exercise equipment Automotive passenger car Trucks/buses Off-highway and off-road vehicles Flexible CAN Solutions Microchip s stand-alone and integrated CAN solutions are flexible and adapt to your design needs. For a quick CAN upgrade to an existing design using any PIC microcontroller, add an MCP2515 stand-alone CAN controller and an MCP2551 CAN transceiver to create a complete CAN node. This option is suited for those new to incorporating CAN functionality into their designs or for designs needed to address CAN and non-can applications on the same board. Many PIC microcontrollers feature an integrated CAN peripheral. When combined with an MCP2551 CAN transceiver, a complete CAN node is created saving board space and cost. Microchip also offers instant DeviceNet protocol support with new PIC Flash microcontrollers featuring Technology. Whatever your CAN bus requirements are power regulation, sensing or motor control Microchip has the solution to fit your design needs.

PIC Flash Microcontrollers with Integrated CAN Microchip offers a complete line of 8- and 16-bit microcontrollers to meet the needs of high-performance embedded applications using the CAN bus. Microchip s portfolio of 8-bit Flash microcontrollers with integrated CAN 2.0B functionality allows execution of complex control algorithms and network interfaces on the same device. On-chip peripherals include A/D converters, comparators, pulse-width modulators, USART (RS485, RS232, LIN), and Master I 2 C /SPI. Based on its PMOS Electrically Erasable Cell (PEEC) process technology, Microchip has developed world class Flash and data EEPROM memory. PEEC offers industry-leading endurance of one million erase/write cycles and data retention of greater than 40 years (100 years typical) specified over the entire operational temperature and voltage range for the device. Microchip s PEEC Flash technology reduces development cost, increases reliable operation, and extends the overall product life. Technology Microchip s innovative technology offers designers an easy-to-use, scalable CAN 2.0B solution with the ability to switch between standard CAN operations and FIFO mode. The scaling flexibility of technology allows for customized design modules from data-byte fitting and CAN protocol bridges to standard CAN communication. In addition to the standard Bosch CAN specifications, the module is also capable of supporting the DeviceNet protocol, giving even greater design flexibility. module features include: Conforms to CAN 2.0B ACTIVE Specification Fully backward compatible with PIC18XXX8 CAN modules Three modes of operation: Legacy, Enhanced Legacy, FIFO 16 full 29-bit acceptance filters with dynamic association ISO/WD 16845 conformance Three dedicated transmit buffers with prioritization Two dedicated receive buffers 6 configurable RX/TX buffers DeviceNet data byte filter support Automatic RTR CAN Interface Products In addition to microcontrollers with integrated CAN ports, Microchip offers stand-alone peripherals designed to provide flexible, economical options for implementing complete CAN nodes. Stand-alone CAN Controller with SPI Interface The new 18-pin MCP2515 provides a pin and function compatible upgrade path from Microchip s first stand-alone CAN controller, the MCP2510. You can now easily migrate your designs to this lowercost, more robust solution. The MCP2515 features an industry standard SPI serial interface, enabling an easy connection to virtually any microcontroller. Numerous enhancements include faster throughput, data-byte filtering for use with Higher Layer Protocols (HLPs), and a Start Of Frame (SOF) output for use with time-slot based protocols. The SOF output lets you implement time-slot based protocols and can also be used in CAN bus diagnostics for determining early bus degradation. This device has the ability to filter messages on the first two data bytes in addition to the standard identifier bits. This functionality is useful when supporting HLPs like DeviceNet that utilize data bytes in addition to identifier bits for determining whether CAN messages should be received and processed by certain nodes. CAN I/O Expanders The MCP250XX family of CAN I/O expanders connect to a CAN network and have input/ output functionality that can be manipulated over the bus without a microcontroller in the system. This family of CAN I/O expanders is targeted at thin client CAN nodes where complex functionality is not required. Additionally, it provides inexpensive alternatives to microcontrollers with integrated CAN. Available in small 14-pin PDIP and SOIC packages, these devices are ideal for enabling small, simple, remotely located CAN nodes. CAN Transceiver The MCP2551 is an ISO11898 compatible, high speed CAN transceiver. Its industry standard pinout and functionality allow it to be used in existing high speed CAN transceiver applications while offering customers improvements in system robustness. These improvements include wider transient and short circuit voltage ranges, and shorter propagation delays.

Operating under the free MPLAB Integrated Development Environment, Microchip s development systems are easy-to-use and help reduce design time. In addition, the Company offers low-cost CAN Development Kits for its CAN controllers and I/O expanders. PIC18 CAN Demonstration Boards The PICDEM CAN-LIN 1, 2 and 3 boards demonstrate the main features of PIC18CXX8, PIC18FXX8 and PIC18F6680/8680 respectively, including those features of the integrated CAN module. These boards also employ a Local Interconnect Network (LIN) subnetwork using Microchip s PIC16C43X LIN microcontroller family. MCP2515/2510 CAN Developer s Kit This kit is a multifunction tool that speeds implementation of the MCP2515/2510 stand-alone CAN controllers by offering functions for controlling its feature-set. This tool can also be used to demonstrate basic CAN input/output functionality and monitor bus activity on the user s CAN bus. It is ideal for new CAN users who want to understand how CAN may be implemented for network communication. MCP250XX CAN I/O Expanders Developer s Kit This kit includes everything needed to create a CAN-based system with Microchip s CAN I/O expander family.
