UJA1164
Mini high-speed CAN system basis chip with Standby mode &
watchdog
Rev. 2 — 17 April 2014
Product data sheet
1. General description
The UJA1164 is a mini high-speed CAN System Basis Chip (SBC) containing an
ISO 11898-2/5 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
UJA1164 can be operated in a very low-current Standby mode with bus wake-up
capability and supports ISO 11898-6 compliant autonomous CAN biasing.
The UJA1164 implements the standard CAN physical layer as defined in the current
ISO11898 standard (-2 and -5). Pending the release of the updated version of ISO11898
including CAN FD, additional timing parameters defining loop delay symmetry are
included. This implementation enables reliable communication in the CAN FD fast phase
at data rates up to 2 Mbit/s.
A number of 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 UJA1164 to meet the requirements of different applications.
