Application note
ECU level diagnostic with SPC563Mx and SPC564Ax
Introduction
The continuous need for quality improvements in automotive is creating focus on ECU
(Engine Control Unit) level diagnostic tools as the analysis of traceability information and
first level diagnostic should be done as early as possible to improve analysis cycle time.
This application note is intended to clarify the different tools possible with SPC56x
microcontrollers, the different possibilities offered when the flash is protected and how to
read the traceability information that is stored inside SPC56x flash. This will then allow
OEMs (Original Equipment Manufacturer) to define and implement the right strategy for their
ECUs.
As IP protection and engine tuning is of high importance, the application note is focused on
identifying configurations (software, tools) that do not require to have access to the flash
password.
This application note is only valid for powertrain devices: SPC563Mx and SPC564Ax.
