UG322: Isolated CAN Expansion Board User Guide The Silicon Labs Isolated CAN Evaluation Board is a hardware plugin card for CAN ca- pable EFM32 Starter Kits (STKs). The Isolated CAN EXP is intended to help demon- KEY FEATURES strate and evaluate applications for Silicon Labs isolation and MCU products. Silicon Labs isolation products create a CMOS barrier to protect components while still allowing 20-pin headers for connection to EFM32 for communication and power transfer. Silicon Labs MCU products offer broad solutions starter kits for low-power, indusrial, consumer electronics, and more. Software demos are available Software demos available in Simplicity for connectiong the MCU to the Isolated CAN EXP and can be downloaded and run Studio through Simplicity Studio. The demos are able to send signals across the isolation barri- Power and communication over isolation er and the message be seen by the user on the screen of the MCU STK. They also barrier showcase Silicon Labs ISOVolt technology as the MCU powers components across the Jumpers for easy manual control of input isolation barrier. signals Note: For full use and evaluation of the Isolated CAN EXP, a CAN capable MCU STK is needed, like the EFM32GG11 STK (STK3701). Software examples are provided for the EFM32 Giant Gecko 11 Starter Kit EFM32GG-STK3701. silabs.com Building a more connected world.
