FAQ
Q: What does the “/3” suffix mean?
A: The /3 variant includes I/O level adaptation (VIO pin), allowing direct connection to 3.3 V microcontrollers.
Q: Does the TJA1051 support CAN FD?
A: Yes, it supports CAN FD data rates up to 5 Mbit/s.
Q: Can it replace a TJA1050 in an existing design?
A: In most designs yes — the TJA1051 offers improved EMC and additional operating modes, but verify pinout and mode control against your schematic.
