Abstract The TJA1041/TJA1041A is an advanced high speed CAN transceiver for
use in automotive and general industrial applications. CAN (Controller
Area Network) has become the de-facto standard protocol for serial
in-vehicle bus communication, particularly for Powertrain and Body
Multiplexing.
The TJA1041/TJA1041A features the low power management known from
the Fault Tolerant CAN Transceiver TJA1054. Accordingly, the
TJA1041/TJA1041A is predestined for Electronic Control Units (ECUs),
which are continuously supplied by battery regardless of ignition key.
Furthermore, the TJA1041/TJA1041A offers enhanced diagnosis features.
Local failures, like short circuits between pins, as well as bus wiring
failures are detected and reported to the host microcontroller.
Interoperability with the high speed CAN transceivers PCA82C250/251,
TJA1050 and TJA1040 from NXP Semiconductors is also considered.
