High-speed CAN transceiver with Standby mode

Rev. 7 — 8 May 2012

Product data sheet

1. General description

The TJA1042 is a high-speed CAN transceiver that provides an interface between a

Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus.

The transceiver is designed for high-speed (up to 1 Mbit/s) CAN applications in the

automotive industry, providing the differential transmit and receive capability to (a

microcontroller with) a CAN protocol controller.

The TJA1042 belongs to the third generation of high-speed CAN transceivers from NXP

Semiconductors, offering significant improvements over first- and second-generation

devices such as the TJA1040. It offers improved ElectroMagnetic Compatibility (EMC)

and ElectroStatic Discharge (ESD) performance, and also features:

• Ideal passive behavior to the CAN bus when the supply voltage is off

• A very low-current Standby mode with bus wake-up capability

• TJA1042T/3 and TJA1042TK/3 can be interfaced directly to microcontrollers with

supply voltages from 3 V to 5 V

These features make the TJA1042 an excellent choice for all types of HS-CAN networks,

in nodes that require a low-power mode with wake-up capability via the CAN bus.

2. Features and benefits

2.1 General

 Fully ISO 11898-2 and ISO 11898-5 compliant

 Suitable for 12 V and 24 V systems

 Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)

 V_IOinput on TJA1042T/3 and TJA1042TK/3 allows for direct interfacing with 3 V to 5 V

microcontrollers (available in SO8 and very small HVSON8 packages respectively)

 SPLIT voltage output on TJA1042T for stabilizing the recessive bus level (available in

SO8 package only)

 Available in SO8 and HVSON8 packages

 Leadless HVSON8 package (3.0 mm  3.0 mm) with improved Automated Optical

Inspection (AOI) capability

 Dark green product (halogen free and Restriction of Hazardous Substances (RoHS)

compliant)

2.2 Low-power management

 Very low-current Standby mode with host and bus wake-up capability

 Functional behavior predictable under all supply conditions
