Product details

CAN FD transceiver for the 150°C junction bus

8 Mbps CAN FD and the 200 mV hysteresis margin

The 8 Mbps data rate supports CAN FD. The receiver hysteresis of 200 mV improves bus noise immunity.

That answers the compatibility question: the TCAN1057AVDDFRQ1 expects a 5 V VCC, so a 3.3 V microcontroller needs a level translator on the TXD/RXD lines or a 5 V-tolerant controller I/O. The SOT-23-8 package is a small-footprint 8-pin part that routes the CANH, CANL, VCC, GND, TXD, RXD, and STB (standby) pins — the PCB layout engineer should keep the differential pair traces matched and the decoupling capacitor within 5 mm of the VCC pin.

Frequently asked questions

Does TCAN1057AVDDFRQ1 support CAN FD?

Yes. The transceiver is rated for 8 Mbps data rate, which covers the CAN FD flexible data-rate phase. It is backward-compatible with classic CAN 2.0 networks.

Is TCAN1057AVDDFRQ1 compatible with 3.3V microcontrollers?

A 3.3 V microcontroller can interface through a level translator or a 5 V-tolerant I/O on the TXD and RXD pins.
