UJA1076ATW

UJA1076A High-speed CAN core system basis chip Rev. 2 — 31 January 2011 Product data sheet 1. General description The UJA1076A core System Basis Chip (SBC) replaces the basic discrete components commonly found in Electronic Control Units (ECU) with a high-speed Controller Area Network (CAN). The UJA1076A supports the networking applications used to control power and sensor peripherals by using a high-speed CAN as the main network interface. The core SBC contains the following integrated devices: High-speed CAN transceiver, inter-operable and downward compatible with CAN transceiver TJA1042, and compatible with the ISO 11898-2 and ISO 11898-5 standards Advanced independent watchdog (UJA1076A/xx/WD versions) 250 mA voltage regulator for supplying a microcontroller; extendable with external PNP transistor for increased current capability and dissipation distribution Separate voltage regulator for supplying the on-board CAN transceiver 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 single package, the core SBC offers an intelligent combination of system-specific functions such as: Advanced low-power concept Safe and controlled system start-up behavior Detailed status reporting on system and sub-system levels The UJA1076A is designed to be used in combination with a microcontroller that incorporates a CAN controller.
