EasySYNC released its CAN-DP serial-to-CANbus converter modules.
This new hardware offering enables engineers to quickly and simply add a CANbus port to their PC or embedded system by connection through a serial interconnect.
The dual in-line package (DIP) form factor utilised by the modules means they fit into standard 28-pin, 0.6-inch IC sockets, optimising them for inclusion in OEM designs or on prototyping boards to assist the development process. Each CAN-DP module supports operation through both RS232 and transistor-transistor logic (TTL) serial interfaces. They can deal with speeds of up to 1Mbit/s on both their serial and CANbus interfaces.
The integrated electronics used by these modules includes a PIC18F4680 8-bit microcontroller unit (MCU) with ECAN control function and 10-bit analogue-to-digital converter (ADC), plus a MCP2551 CANbus transceiver IC. The MCU runs firmware that converts the data from its serial/UART format to the CANbus protocol. The CANbus transceiver IC converts logic level signals from the PIC microcontroller’s CANbus interface into CANbus physical signals.
