XR31233EDTR
Overview
The XR31233EDTR is a low-power, high-speed CAN transceiver designed for 3.3V systems. It provides the physical layer interface between the CAN protocol controller and the physical differential bus, supporting data rates up to 1Mbps while featuring +/-36V fault protection.
Why Choose This Part
This transceiver operates from a single 3V to 3.6V supply, eliminating the need for 5V rails in modern low-voltage designs. It features 100mV of receiver hysteresis for improved noise rejection and is 5V tolerant on digital I/O pins, simplifying interfacing with legacy controllers.
Applications
Key Specifications
Getting Started
To implement this part, ensure a 120-ohm termination resistor is placed at each end of the CAN bus. For evaluation, use an NSOIC-8 breakout board and connect the TXD and RXD pins to a CAN-capable microcontroller such as an STM32 or ESP32 with appropriate level shifting if necessary.
