Advance Information

SBC Gen2 with CAN High Speed

and LIN Interface

33903/

33903/4/5

The 33903/4/5 is the second generation family of System Basis

Chips, which combines several features and enhances present module

designs. The device works as an advanced power management unit for

the MCU, 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 mode. The SBC may include one or two LIN 2.1

interfaces with LIN output pin switches. It includes up to four wake-up

input pins than can also be configured as output drivers for flexibility.

SYSTEM BASIS CHIP

This device implements multiple Low Power modes, with very low-

current consumption. In addition, the device is part of a family concept

where pin compatibility, among the various devices with and without

LIN interfaces, add versatility to module design.

The 33903/4/5 also implements an innovative and advanced fail-safe

state machine and concept solution.

ORDERING INFORMATION

Features

See Device Variations on page 2

• 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

• Extremely low quiescent current in low power modes

• Fully-protected embedded 5.0 V regulator for the CAN driver

• Multiple under-voltage 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 over-current detection and under-voltage 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 low power modes: CAN or LIN bus, I/O

transition, automatic timer, SPI message, and V_DDover-current

detection.

• ISO11898-5 high speed CAN interface compatibility for baud rates of

40 kb/s to 1.0 Mb/s

• Pb-free packaging designated by suffix code EK
