UJA1169A Mini high-speed CAN system basis chip Rev. 1 12 May 2020 Product data sheet 1. General description The UJA1169A is a mini high-speed CAN System Basis Chip (SBC) containing an ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant HS-CAN transceiver including CAN FD up to 5 Mbit/s and an integrated 5 V or 3.3 V 250 mA scalable supply (V1) for a microcontroller and/or other loads. It also features a watchdog and a Serial Peripheral Interface (SPI). The UJA1169A can be operated in very low-current Standby and Sleep modes with bus and local wake-up capability. The microcontroller supply is switched off in Sleep mode. The UJA1169A comes in six variants. The UJA1169ATK, UJA1169ATK/F, UJA1169ATK/X and UJA1169ATK/X/F contain a 5 V regulator (V1). V1 is a 3.3 V regulator in the UJA1169ATK/3 and the UJA1169ATK/F/3. The UJA1169ATK, UJA1169ATK/F, UJA1169ATK/3 and UJA1169ATK/F/3 variants feature a second on-board 5 V regulator (V2) that supplies the internal CAN transceiver and can also be used to supply additional on-board hardware. The UJA1169ATK/X and UJA1169ATK/X/F are equipped with a 5 V supply (VEXT) for off-board components. VEXT is short-circuit proof to the battery, ground and negative voltages. The integrated CAN transceiver is supplied internally via V1, in parallel with the microcontroller. The UJA1169Axx/F variants support ISO 11898-2:2016 compliant CAN partial networking with a selective wake-up function incorporating CAN FD-passive. CAN FD-passive is a feature that allows CAN FD bus traffic to be ignored in Sleep/Standby mode. CAN FD-passive partial networking is the perfect fit for networks that support both CAN FD and classic CAN communications. It allows normal CAN controllers that do not need to communicate CAN FD messages to remain in partial networking Sleep/Standby mode during CAN FD communication without generating bus errors. The UJA1169A implements the standard CAN physical layer as defined in ISO 11898-2:2016. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s. A dedicated LIMP output pin is provided to flag system failures. A number of configuration settings are stored in non-volatile memory. This arrangement makes it possible to configure the power-on and limp-home behavior of the UJA1169A to meet the requirements of different applications.UJA1169A NXP Semiconductors Mini high-speed CAN SBC with optional partial networking 2.
