UJA1079 LIN core system basis chip Rev. 02 — 27 May 2010 Product data sheet 1. General description The UJA1079 core System Basis Chip (SBC) replaces the basic discrete components commonly found in Electronic Control Units (ECU) with a Local Interconnect Network (LIN) interface. The UJA1079 supports the networking applications used to control power and sensor peripherals by using the LIN interface as a local sub-bus. The core SBC contains the following integrated devices: • LIN transceiver compliant with LIN 2.1, LIN 2.0 and SAE J2602, and compatible with LIN 1.
