Frequently Asked Questions (FAQ)
Q1: Does the TCAN337GDCNT support CAN FD?
No, the device is only compatible with the Classic CAN protocol , with a maximum communication rate of 1 Mbps . If your application requires support for CAN FD (up to 5 Mbps segment rate), we recommend using TI’s TCAN1042/TCAN1043 series transceivers.
Q2: Can it interface directly with a 3.3V MCU?
Yes, the TCAN337GDCNT provides a VIO pin for logic level matching, supporting 3.3V or 5V logic input/output. Therefore, it is directly compatible with the 3.3V I/O interface of mainstream MCUs (such as STM32, NXP, TI C2000, etc.) without the need for level conversion circuitry.
