Small I/O expanders for 'thin client' CAN applications

30 January 2002 Telecoms, Datacoms, Wireless, IoT

Microchip has expanded into the low-end 'thin-client' CAN applications market with its family of input/output expanders. Microchip says it is currently the only semiconductor manufacturer to offer a small-packaged, full-featured, cost-effective alternative to microcontroller-based solutions with its family of MCP250XX I/O expanders. These small 14-pin PDIP or SOIC package devices have full CAN 2,0B Active capability, enabling transmits and receives of both standard and extended frames at up to 1 Mbps. Functionality includes eight I/O pins that can be configured as inputs or outputs. Analog input capability exists on selected versions with up to four 10 bit A/D converters. The devices can be configured to automatically transmit CAN messages on changes of either analog or digital inputs. Incoming CAN messages can change pin states or PWM output frequencies.

The MCP25025 and MCP25055 feature connected RxCAN and TxCAN pins for one-wire communication, providing a simple way to connect a small number of nodes together.

For thin client application a complete CAN node can be implemented using a single microchip CAN I/O expander, and once configured and running on a CAN bus the MCP250XX devices can be reconfigured through CAN bus messages, enhancing overall system flexibility.
