Doc ID 16196 Rev 2

Even when high protection level is enabled, SPC563Mx and SPC564Ax allow to upload

software in RAM and to run it without having to distribute any private password to users.

This allows then to execute MCU specific self tests, ASSP self tests, power stage self tests.

Tools for ECU level diagnostic

Different tools can be used for ECU level diagnostic.

Third party tools allowing connection to the selected communication interface can be used

(ex: Vector, Etas,..). Some of those tools are also available for external use and for extended

temperature range.

Tools from STMicroelectronics

STMicroelectronics has developed tools for SPC56x for use in lab environment (indoor, 25

typ. ambient temperature). The tools to be used for ECU level diagnostics are:

●

Target connection = ST Combox (CAN or UART)

●

PC software = CPUcommander

Please, note that the use of CPUcommander requires development of few software to select

the right communication parameters and to define the format of traceability information.

This tool also allows to upload a user defined software and run it in the ECU.
