UJA1066TW/3V3/T General Description

Networking Interface 32-HTSSOP

Key Features

2.1 General
Contains a full set of CAN ECU functions:
CAN transceiver
Voltage regulator for the microcontroller (3.3 V or 5.0 V)
Separate voltage regulator for the CAN transceiver (5 V)
Enhanced window watchdog with on-chip oscillator
Serial Peripheral Interface (SPI) for the microcontroller
ECU power management system
Fully integrated autonomous fail-safe system
Designed for automotive applications:
Supports 14 V and 42 V architectures
Excellent ElectroMagnetic Compatibility (EMC) performance
Battery and CAN-bus pins are protected against transients in accordance with ISO 7637-3
Very low sleep current
Supports remote flash programming via the CAN-bus
Small 8 mm × 11 mm HTSSOP32 package with low thermal resistance
2.2 CAN transceiver
ISO 11898-2 and ISO 11898-5 compliant high-speed CAN transceiver
Enhanced error signalling and reporting
Dedicated low dropout voltage regulator for the CAN-bus:
Independent of the microcontroller supply
Guarded by CAN-bus failure management
Significantly improves EMC performance
Partial networking option with global wake-up feature; allows selective CAN-bus communication without waking up sleeping nodes
Bus connections are truly floating when power is off
SPLIT output pin for stabilizing the recessive bus level
2.3 Power management
Smart operating modes and power management modes
Cyclic wake-up capability in Standby and Sleep modes
Local wake-up input with cyclic supply feature
Remote wake-up capability via the CAN-bus
External voltage regulators can easily be incorporated into the power supply system (flexible and fail-safe)
42 V battery-related high-side switch for driving external loads such as relays and wake-up switches
Intelligent maskable interrupt output
2.4 Fail-safe features
Safe and predictable behavior under all conditions
Programmable fail-safe coded window and time-out watchdog with on-chip oscillator, guaranteeing autonomous fail-safe system supervision
Fail-safe coded 16-bit SPI interface for the microcontroller
Global enable pin for the control of safety-critical hardware
Detection and detailed reporting of failures:
On-chip oscillator failure and watchdog alerts
Battery and voltage regulator undervoltages
CAN-bus failures (short circuits and open-circuit bus wires)
TXD and RXD clamping situations and short circuits
Clamped or open reset line
SPI message errors
Overtemperature warning
ECU ground shift (two selectable thresholds)
Rigorous error handling based on diagnostics
Supply failure early warning allows critical data to be stored
23 bits of access-protected RAM available (e.g. for logging cyclic problems)
Reporting in a single SPI message; no assembly of multiple SPI frames needed
Limp-home output signal for activating application hardware in case system enters Fail-safe mode (e.g. for switching on warning lights)
Fail-safe coded activation of Software development mode and Flash mode
One SPI readable device type identification
Software-initiated system reset
