Document Number: MC33903_4_5

Rev. 10.0, 2/2014

SBC Gen2 with CAN High Speed

and LIN Interface

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. This device is powered by SMARTMOS

technology.

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.
