Latest Click board adds isolated CAN for automation and IIoT use
The latest Click board from MikroElektronika (Mikroe) is the CAN Isolator 3, a compact add-on board which provides isolated CAN communication to reduce development time for automation and IIoT applications.
The board features the MAX14882, an isolated CAN transceiver with an integrated transformer driver from Analog Devices. It is galvanically isolated between the device’s CAN-protocol controller side (TDX, RDX) and the physical wires of the CAN network (CANH, CANL) cable-side/bus-side of the transceiver. The MAX14882 provides up to 5kV RMS of galvanic isolation for 60 seconds and a continuous working voltage of up to 848V RMS while operating at the maximum high speed CAN data rate of 1Mbits per second.
Features include a wide supply voltage range for the CAN controller interface (3.0 to 5V), field bus polarity control (PoL), an integrated transformer driver for power transfer to the bus side and an integrated LDO for powering the CAN bus side. The CAN bus controller exceeds the ISO 11898 specifications requirement of -2.0 to +7V with ±25V receiver input common-mode range. The CANH and CANL IOs are fault tolerant up to ±54V and are protected from electronic discharge (ESD) up to ±15KV to GNDB on the bus side.
The CAN Isolator 3 Click board is suitable for a range of development projects, including automation, industrial controls, HVAC and switch gear systems. It includes a library of functions and an example code that can be used as a reference for further development.
MikroElektronika (Mikroe) says it wants to change the embedded electronics industry through the use of industry standard hardware and software solutions. In 2011, the company invented the mikroBUS development socket standard and the compact Click boards for peripherals that use the standard to cut development time.
Now the company offers more than 1450 Click boards – 10 times more than competitors, says Mikroe – and the mikroBUS standard is included by many leading microcontroller companies on their development boards.
SiBRAIN is Mikroe’s standard for MCU development add-on boards and sockets and the company’s DISCON standard enables uses to choose between a variety of supported LCDs and touchscreen options. Mikroe also offers NECTO, claimed to be the world’s most flexible IDE, as well as a range of compilers, plus development boards, programmers and debuggers. MIKROE’s Planet Debug is believed to be the embedded industry’s first hardware-as-a-service and enables designers to develop and debug embedded systems remotely over the internet without investing in hardware.
