OR:  

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.

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.

Features and benefits

General

  • ISO 11898-2 and ISO 11898-5 compliant high-speed CAN transceiver
  • 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 and on pin BAT
  • 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 mode with full wake-up capability
  • Leadless HVSON14 package (3.0 mm  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
  • Undervoltage reset with selectable detection thresholds: 60 %, 70 %, 80 % or 90 % of output voltage
  • Excellent transient response with a 4.7 μF ceramic output capacitor
  • Short-circuit to GND/overload protection on pin V1

Power Management

  • Standby mode featuring very low supply current; voltage V1 remains active to maintain the supply to the microcontroller
  • Remote wake-up capability via standard CAN wake-up pattern
  • Wake-up source recognition
  • Remote wake-up can be disabled to reduce current consumption

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
