Some problems with UJA1078

[ZhaozhangChen]

Dear Support,

UJA1078 High-speed CAN transceiver, inter-operable and downward compatible with CAN transceiver TJA1042, and compatible with the ISO 11898-2 and ISO 11898-5 standards.

1. UJA1078 supports ISO 16845 standard?

2.Confirm contains filtering to detect valid remote wake up event?

3.Confirm the CAN transceiver voltage reference pins are open circuit?

Dear Zhaozhang,

1. The integrated HS-CAN transceiver is ISO 11898-2 and 11898-5 compliant.

2. There is a filter at the receiver input that prevents unwanted wake-up events occurring due to automotive transients or EMI.

The wake-up sequence consists of a recessive, dominant, recessive, dominant signal on the CAN-bus within the specified time:

Wake-up frame (WUF) detection is not supported.

3. I do not fully understand this question. Can you please rephrase it or provide more details?

Best regards,

Tomas
