System Basis Chip with CAN
High Speed and LIN Interface
I3n34d49u90s03t3/r4/i/a5l
The 34903/4/5 is the second generation family of the System Basis
Chip (SBC). It combines several features and enhances present
module designs. The device works as an advanced power
management unit for the MCU with additional integrated circuits such
as sensors and CAN transceivers. It has a built-in enhanced high-speed
CAN interface (ISO11898-2 and -5) with local and bus failure
diagnostics, protection, and fail-safe operation modes. The SBC may
include zero or one LIN 2.1 interface with LIN output pin switches. It
includes up to four wake-up input pins that can also be configured as
output drivers for flexibility. This device is powered by SMARTMOS
technology.
SYSTEM BASIS CHIP
This device implements multiple Low-power (LP) modes, with very
low-current consumption. In addition, the device is part of a family
concept where pin compatibility adds versatility to module design.

32-PIN SOIC
The 34903/4/5 also implements an innovative and advanced fail-safe
state machine and concept solution.
Applications
Features
• Industrial process control
• Voltage regulator for MCU, 5.0 or 3.3 V, part number selectable, with
possibility of usage external PNP to extend current capability and
share power dissipation
• Voltage, current, and temperature protection
• Automation
• Motor control
• Robotics
• Extremely low quiescent current in LP modes
• Fully-protected embedded 5.0 V regulator for the CAN driver
• Multiple undervoltage detections to address various MCU
specifications and system operation modes (i.e. cranking)
• Auxiliary 5.0 or 3.3 V SPI configurable regulator, for additional ICs,
with overcurrent detection and undervoltage protection
• MUX output pin for device internal analog signal monitoring and
power supply monitoring
• Advanced SPI, MCU, ECU power supply, and critical pins
diagnostics and monitoring.
• Multiple wake-up sources in LP modes: CAN or LIN bus,
I/O transition, automatic timer, SPI message, and VDD overcurrent
detection.
• ISO11898-5 high-speed CAN interface compatibility for baud rates of
40 kb/s to 1.0 Mb/s
• Scalable product family of devices ranging from 0 to 1 LIN,
compatible to J2602-2 and LIN 2.1

Notes
1. The voltage on non-VSUP pins should never exceed the VSUP voltage at any time or permanent damage to the device may occur.
2. If the voltage delta between VSUP/1/2 and VBASE is greater than 6.0 V, the external VDD ballast current sharing functionality may be
damaged.
3. Potential Electrical Over Stress (EOS) damage may occur if RXD is in contact with VE while the device is ON.
