Technical Data

SBC Gen2 with CAN High Speed

and LIN Interface

33903/

33903/4/5

The 33903/4/5 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, one or two LIN 2.1 interfaces with LIN output pin switches.

It includes up to four wake-up input pins that can also be configured as

output drivers for flexibility.

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.

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

state machine and concept solution.

Features

• 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 LP 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 LP 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

• Scalable product family of devices ranging from 0 to 2 LINs which are 

compatible to J2602-2 and LIN 2.1

Freescale Semiconductor, Inc. reserves the right to change the detail specifications,

as may be required, to permit improvements in the design of its products.
