NXP Semiconductors UJA1079

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 1.3 • Advanced independent watchdog (UJA1079/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 Pnterface (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 single package, the core SBC offers an...
