These are listed under Flash Target Parameters in the datasheet.

I've tried to claculate these speeds Erase Speed, Program Speeds and my results were as follows and need your confirmation:

For Prgram Flash: Erase Speed = Size/Complete Erase Time= 8MByte/17s= 0.47MB/S

Write Speed= Size/Complete Program Time= 8Mbyte/7.2s=1.11MB/s

For Data Flash: Erase Speed= Size/Complete Erase Time= 768kByte/17s= 45.18kByte/Sec= 0.044MB/S
Write Speed: Burst Size/Data Flash program time per burst=32/(96+4400/100)=32/140=0.22MB/S

So please appreciate your confirmation is my results are right or wrong?

That's right. The erase times are a worst case, assuming cold temperature and very tired flash. The typical (not guaranteed) erase times are much less (e.g., 170 ms instead of 1000 ms).

Thank you Wrangler for your continuous support, Can you confirm this result also is it right or wrong?
For Part Number: XC2238N-40FxLR
https://www.infineon.com/dgdl/Infineon-SAK-XC2238N-40F80LR%20AB-DataSheet-v01_06-EN.pdf?fileId=5546d...
Erase Speed= Size/Erase Time= 320kByte/8ms=40Mbyte/S
Program Speed=320kByte/3.5ms= 91.43 Mbyte/S

Appreciate your confirmation if this right or wrong?

For the XC2, the sector size is 4K.

So, erase: 4K sector / 8 ms => 500K/sec
Program: 128 byte page / 3.5 ms => 36K/sec

Hello,
Kindly, How can I calculate Erase Speed, Write Speed for TC1791 for both Data Flash, Program Flash? as I found erase Time, Write Time per Page or per sector but I can't find the size of page or sector?
This is the datasheet:
https://www.infineon.com/dgdl/Infineon-TC1791-DS-v01_01-en.pdf?fileId=db3a30433580b3710135afe8eb4756...

Appreciate your fast response

Page size in PFlash is 256 bytes, in DFlash 128 bytes.
The PFlash has 8 sectors with 16K, 1 sector with 128K and all other sectors haven 256K.
Each DFlash has 1 sector.
More information you can find in the user manual of the device:

32linesx48bits=1536bits=0,192kbyte
or you need another information?
Cache memory has nothing to do with flash erase/program time.
