safety systems by allowing the designer
to scale a design for the number of firinig
loops needed while providing enhanced
safety and system reliability.
SafeAssure Program:
Functional Safety, Simplified
Freescale’s SafeAssure functional safety
program is designed to help system
manufacturers more easily achieve system
compliance with functional safety standards:
International Standards Organization (ISO)
26262 and International Electrotechnical
Commission (IEC) 61508. The program
highlights Freescale solutions – hardware
and software – that are optimally designed
to support functional safety implementations
and come with a rich set of enablement

Question – Why are there no squib
drivers integrated?
system supplier who addressed the
need for low cost vs. flexibility.
?
Supports complete airbag system
power supply architecture, including
supplies for squib firing (33 V), satellite
sensors (6.3 V), and local ECU
sensors and logic circuits (5.0 V)
Answer – The number of squib
drivers varies across vehicle
platforms so a fixed number could
be too many or not enough for an
application.
?
Question – Is the MC33789’s PSI5
Interface interoperable with other
PSI5 products?
Answer – Yes, Freescale is part of
the PSI5 consortium and has an
?
?
?
Nine configurable switch input monitors
for simple switch and Hall-effect sensor
interfaces with internal power supply
16-bit SPI interface
LIN 2.1 physical layer interface.
?
Question – What drove the MC33789
final silicon partition?
Answer – The MC33789 was the
result of collaboration between
Freescale and a leading airbag
ecosystem of crash sensor parts that
communicate with the MC33789. The
MC33789’s PSI5 master interface
supports the P10P 500/3L operation
mode specified in the PSI5 standard
V1.3.
