Product Description

Overview
The UJA1167 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 UJA1167 can be operated in very low-current Standby and Sleep modes with bus and local wake-up capability and supports ISO 11898-6 compliant autonomous CAN biasing. The microcontroller supply is switched off in Sleep mode. The UJA1167TK version contains a battery-related high-voltage output (INH) for controlling an external voltage regulator, while the UJA1167TK/VX is equipped with a 5 V sensor supply (VEXT).
The UJA1167 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 UJA1167 to meet the requirements of different applications.

## Features
### General
* ISO 11898-2 and ISO 11898-5 compliant high-speed CAN transceiver
* Loop delay symmetry timing enables reliable communication at data rates up to 2 Mbit/s in the CAN FD fast phase
* Autonomous bus biasing according to ISO 11898-6
* Fully integrated 5 V/100 mA low-drop voltage regulator for 5 V microcontroller supply (V1)
* Bus connections are truly floating when power to pin BAT is off
### Designed for automotive applications
* ±8 kV ElectroStatic Discharge (ESD) protection, according to the Human Body Model (HBM) on the CAN bus pins
* ±6 kV ESD protection, according to IEC 61000-4-2 on the CAN bus pins, the sensor supply output VEXT and on pins BAT and WAKE
* CAN bus pins short-circuit proof to ±58 V
* Battery and CAN bus pins protected against automotive transients according to ISO 7637-3
* Very low quiescent current in Standby and Sleep modes with full wake-up capability
* Leadless HVSON14 package (3.0 mm x 4.5 mm) with improved Automated Optical Inspection (AOI) capability and low thermal resistance
* Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)
### Low-drop voltage regulator for 5 V microcontroller supply (V1)
* 5 V nominal output; ±2 % accuracy
* 100 mA output current capability
* Current limiting above 150 mA
* On-resistance of 5 Ω (max)
* Support for microcontroller RAM retention down to a battery voltage of 2 V

* Excellent transient response with a 4.7 μF ceramic output capacitor
* Short-circuit to GND/overload protection on pin V1
* Turned off in Sleep mode
### Power Management
* Standby mode featuring very low supply current; voltage V1 remains active to maintain the supply to the microcontroller
* Sleep mode featuring very low supply current with voltage V1 switched off
* Remote wake-up capability via standard CAN wake-up pattern
* Local wake-up via the WAKE pin
* Wake-up source recognition
* Local and/or remote wake-up can be disabled to reduce current consumption
* High-voltage output (INH) for controlling an external voltage (UJA1167TK)
### System control and diagnostic features
* Mode control via the Serial Peripheral Interface (SPI)
* Overtemperature warning and shutdown
* Watchdog with independent clock source
* Watchdog can be operated in Window, Timeout and Autonomous modes
* Optional cyclic wake-up in watchdog Timeout mode
* Watchdog automatically re-enabled when wake-up event captured
* Watchdog period selectable between 8 ms and 4 s
* Supports remote flash programming via the CAN bus
* 16-, 24- and 32-bit SPI for configuration, control and diagnosis
* Bidirectional reset pin with variable power-on reset length to support a variety of microcontrollers
* Configuration of selected functions via non-volatile memory
### Sensor supply voltage (pin VEXT of UJA1167TK/VX)
* 30 mA output current capability
* Current limiting above 30 mA
* Excellent transient response with a 4.7 μF ceramic output load capacitor
* Protected against short-circuits to GND and to the battery
* High ESD robustness of ±6 kV according to IEC 61000-4-2
* Can handle negative voltages as low as -18 V
