UJA1079A

UJA1079A LIN core system basis chip Rev. 2 — 31 January 2011 Product data sheet 1. General description The UJA1079A 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 UJA1079A 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 1.3 Advanced independent watchdog (UJA1079A/xx/WD versions) 250 mA voltage regulator for supplying a microcontroller; extendable with external PNP transistor for increased current capability and dissipation distribution Serial Peripheral Interface (SPI) (full duplex) 2 local wake-up input ports Limp home output port In addition to the advantages gained from integrating these common ECU functions in a...
