TJA1042

High-speed CAN transceiver with Standby mode

Rev. 10 — 24 November 2017

Product data sheet

1. General description

The TJA1042 high-speed CAN transceiver 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 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

The TJA1042 implements the CAN physical layer as defined in ISO 11898-2:2016 and

SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication in the

CAN FD fast phase at data rates up to 5 Mbit/s.

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

TJA1042

High-speed CAN transceiver with Standby mode

7. Functional description

The TJA1042 is a HS-CAN stand-alone transceiver with Standby mode. It combines the

functionality of the PCA82C250, PCA82C251 and TJA1040 transceivers with improved

EMC and ESD handling capability and quiescent current performance. Improved slope

control and high DC handling capability on the bus pins provide additional application

flexibility.

The TJA1042 is available in two versions, distinguished only by the function of pin 5:

•

The TJA1042T is backwards compatible with the TJA1040 when used with a 5 V

microcontroller, and also covers existing PCA82C250 and PCA82C251 applications

•

The TJA1042T/3 and TJA1042TK/3 allow for direct interfacing to microcontrollers with

supply voltages down to 3 V

7.1 Operating modes

The TJA1042 supports two operating modes, Normal and Standby, which are selected via

pin STB. See

Table 4

for a description of the operating modes under normal supply

conditions.

7.1.1 Normal mode

A LOW level on pin STB selects Normal mode. In this mode, the transceiver can transmit

and receive data via the bus lines CANH and CANL (see

Figure 1

for the block diagram).

The differential receiver converts the analog data on the bus lines into digital data which is

output to pin RXD. The slopes of the output signals on the bus lines are controlled

internally and are optimized in a way that guarantees the lowest possible EME.

7.1.2 Standby mode

A HIGH level on pin STB selects Standby mode. In Standby mode, the transceiver is not

able to transmit or correctly receive data via the bus lines. The transmitter and

Normal-mode receiver blocks are switched off to reduce supply current, and only a

low-power differential receiver monitors the bus lines for activity. The wake-up filter on the

output of the low-power receiver does not latch bus dominant states, but ensures that only

bus dominant and bus recessive states that persist longer than t

fltr(wake)bus

are reflected on

pin RXD.

In Standby mode, the bus lines are biased to ground to minimize the system supply

current. The low-power receiver is supplied by V

, and is capable of detecting CAN bus

activity even if V

is the only supply voltage available. When pin RXD goes LOW to signal

a wake-up request, a transition to Normal mode will not be triggered until STB is forced

LOW.
