Overview

The TCAN330D is a 3.3V CAN transceiver from Texas Instruments designed for high-speed CAN (Controller Area Network) communications up to 1Mbps. It operates from a single 3V to 3.6V supply, eliminating the need for a 5V rail in low-voltage systems while remaining fully compatible with 5V CAN transceivers. This device is rated for industrial and automotive temperatures ranging from -40 to 125 degrees Celsius.

Why Choose This Part

The TCAN330D allows for direct interfacing with 3.3V MCUs and FPGAs without level shifters, simplifying BOM complexity. It features integrated protection against ESD events and meets the ISO 11898-2 physical layer standard for seamless interoperability with legacy CAN networks.

Applications

Industrial Control Systems
Enables reliable communication between PLCs, sensors, and actuators in 3.3V-only logic environments.
Battery Powered Instruments
Utilizes 3.3V supply rails to minimize power conversion stages in portable field equipment.
Building Automation
Connects HVAC and lighting control nodes over long cable runs using differential signaling.

Getting Started

To evaluate this part, connect the TXD and RXD pins to your microcontroller's CAN controller and place a 120-ohm termination resistor across the CANH and CANL lines at each end of the bus. Ensure decoupling capacitors are placed close to the VCC pin as recommended in the TI layout guidelines. For prototyping, the TCAN330EVM evaluation module can be used to test performance across various load conditions.
