TJA1042T/3/CM,118
Overview
The TJA1042T/3/CM,118 is a high-speed CAN transceiver that provides an interface between a Controller Area Network protocol controller and the physical two-wire CAN bus. It is specifically designed for high-speed CAN applications in the automotive industry, providing differential transmit and receive capability to a CAN protocol controller. This variant features a VIO pin for direct interfacing with microcontrollers operating at supply voltages from 3V to 5V.
Why Choose This Part
This device offers a very low-current Standby mode with bus wake-up capability, significantly reducing power consumption when the network is idle. It provides excellent EMC performance and includes extensive protection features such as 58V bus pin robustness and 8kV ESD handling. The predictable functional behavior under all supply conditions, including undervoltage detection, ensures system stability.
Applications
Getting Started
To evaluate this transceiver, engineers typically use a CAN controller found in most automotive-grade microcontrollers and connect the TXD/RXD pins to the transceiver inputs. Ensure the VCC pin is supplied with 5V while the VIO pin is tied to the microcontroller's I/O voltage level. Hardware prototyping can be accelerated using standard SOIC-8 breakout boards or NXP automotive evaluation kits like the SJA1105SMBEVM.
