UJA1164ATK中文资料Mini high-speed CAN system basis chip with Standby mode & watchdog数据手册恩XP规格书

描述 Description

The UJA1164ATK 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 and an integrated 5 V/100 mA supply for a microcontroller.
It also features a watchdog and a Serial Peripheral Interface (SPI). The UJA1164ATK can be operated in very-low-currentStandby mode with bus wake-up capability and supports 11898-2:2016 compliant autonomous CAN biasing. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s.
Several configuration settings are stored in non-volatile memory, allowing the SBC to be adapted for use in a specific application. This makes it possible to configure the power-on behavior of the UJA1164ATK to meet the requirements of different applications.
