S71KS512SC0: Restrictions on using Flash and RAM simultaneously - KBA234430

Community Translation: S71KS512SC0: FlashとRAMを同時に使用した場合の制約 – KBA234430

Version: **

S71KS512SC0 is a dual-die device including an HYPERFLASH™ die and an HYPERRAM™ die in the package. The RWW (Read While Write) functionality is not qualified on Infineon dual-die devices because it may result in overheating, too much noise on the lines, and high current consumptions which may damage the bonding and the package itself.

The flash and the RAM of the S71KS512SC0 cannot be accessed simultaneously. The main constraint is the shared I/Os between HYPERFLASH™ and HYPERRAM™. Data can’t be copied from HYPERFLASH™ to HYPERRAM™ directly.

SoC-internal RAM should be used as intermediate storage for the data before copying it over to the HYPERRAM™.
