Overview
The MC33903/4/5 is the second generation
family of System Basis Chips, which combin e
several features and enhance present module
designs. The device works as an advanced
power management unit for the MCU and
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/J2602-2 interfaces
with LIN master terminal outputs. It includes
wake-up input pins than can also be configured
as output drivers for flexibility.
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, adds
versatility to module design.
The MC33903/4/5 also implements an
innovative and advanced fail-safe state machine
and concept solution. This family of devices are
supported by an enablement ecosystem that
includes an evaluation board, software interface,
EMC/ESD conformance reports and training
material that allows a faster time to market and
eases your designs.

Features Benefits
Ecosystem
Easy-to-Use Ecosystem Faster time to market.
EVB + SW interface to ease SBC usage & programming.
Electrical and EMC/ESD conformance reports.
Training material.
Energy Management
Ultra Low Power Modes Best-in-class quiescent current down to 15 µA including LIN and
CAN wake-up active.
Reduces contribution of active blocks during stand-by mode.
Innovative Wake-up Event Save time during cyclic check by reducing the number of state
machine transitions. This contributes in reducing overall ECU
energy consumption (Energy = Current x Time).
Scalable Power Supply Enables platform solution (150 mA internal supply, or up to
300 mA with an optional ballast transistor).
System Management
Flexible Fail Safe Modes Flexibility to address th e ECU functional safety assessment and
program the default fail safe behavior via hardware
implementation.
Secured SPI Fast SPI access – higher frequency combine d with new register
addressing methodology to save time.
Parity checks.
Innovative Cranking Pulse
Management System alternative to save customer cost (PCB space, cost of
capacitor) while keeping some degraded functionalities during
cranking mode.
Advanced Watchdog Improved, safer and optional Watchdog (in addition to time-out
and window watchdog) implemente d to avoid unpredictable
Watchdog recognition, so that closed loop MCU activity can be
detected.
Ease Customer Debug Mode The DBG pin is used to inhibit the watchdog during debug mode .
This helps hardware and software designers save time during
application development.
