Can a MCU with RAW NAND hardware with 1bit/528bytes ECC Hamming be used for a RAW NAND with 4-8bit ECC requirements?

Hi,

At the moment I have a MCU that supports only ECC 1bit/528bytes Hamming and it's connected with a RAW NAND Flash with reliability 1-bit ECC per 528 bytes.

Can the same MCU be used for a RAW NAND Flash with reliability with 4-bit ECC per 528 bytes?

Thanks in advance,

Dorin

Hello Dorin,

A MCU that supports only ECC 1bit/528bytes Hamming and it's connected with a RAW NAND Flash with reliability 1-bit ECC per 528 bytes can not be used for a RAW NAND Flash with reliability with 4-bit ECC per 528 bytes. You will need MCU that supports 4 - bit ECC.

Thank you

Regards,

Bushra

I still have a question regarding NAND Flash.

On the NAND Flash Memory Roadmap the S34MS-1 will no longer be producing in the next year.

Is any alternative for a NAND Flash memory that is SLC, 4 or 8Gbit, 1bit ECC and powered by 1V8?

Hello Dorin,

The parts will actually be supported longer than the roadmaps indicates ( at least 1 more year).

Thank you
