TMS570LS1227: EEPROM (BANK7) maximum byte write time

Part Number: TMS570LS1227

Dear all,

The data sheet (SPNS192B, table 6.25, page 83) specifies the BANK7 maximum write time by word size (144 bits) as 300 µs. In our application we only write 16 bytes with ECC disabled, and we need the worst case time for that.

Is there any data available for a maximum write time less than word size e.g., by byte (preferably with ECC disabled)?

Thanks a lot for your time and support!

With my best regards

Luis

  • Hi Luis,

    Apologies for the delay in my response.

    The data sheet (SPNS192B, table 6.25, page 83) specifies the BANK7 maximum write time by word size (144 bits) as 300 µs. In our application we only write 16 bytes with ECC disabled, and we need the worst case time for that.

    Here 144 bits (128+16) means 128bits data and 16bits of ECC. 128bits means 16bytes.

    Even if we disable the ECC also the max delay for the 16bytes write is 300us.

    Is there any data available for a maximum write time less than word size e.g., by byte (preferably with ECC disabled)?

    Actually, there are 144bits of throughput is possible for every write. Even if we write just 1bye also the delay will not change and as mentioned above it would be 300us max.

    That is the reason only they didn't give delay for single byte in the datasheet, because writing single byte will also take the same delay.
