Nor Flash Forum Discussions
I am wondering at what temperature value would this part receive permanent damage and I was unable to find information on its max junction temperature value so if it could also be provided that would be helpful.
Show LessHi everyone,
I want to store some data in to flash device which device is S25HS512T
But ı have got some problem with SPI. When ı send clock and data with CS signals, ı have got just HIGH state on output of S25HS512T. I am going to add some scope picture from osilocope to here.
I have also check power layer and that layer is good.I think, there is not ı can search another thing for solution to problem except SPI.
Where is the problem?Is that about SPI Protocol?
DP: I want to read Status Register 1 with Read Status Register 1 transaction...
Show LessProgram Status bit, bit4 of Status Register, drives to 1 when Program fails. Is this flag set for any reason?
Is 1 set in Program status bit of Status register even when programming fails due to exceeding 100K of P/E Endurance?
Show LessI have a problem that I can program Status and Configuration Register using 0x01 command at the first time after the flash powered on, but when I try to re-program the Register, the operation fails and Status Register value becomes 0x5F. Then I I power on the flash again, the value Status and Configuration Register becomes all 0.
How many times can this Registers be programmed. I have programmed the Register about 200,000 times, is it because I have exhausted the use times. Or it is because of some other reasons.
Show LessDear Sir,
客户目前在选型与Altera FPGA (具体FPGA型号:5ceba4U15)搭配使用的Nor Flash,主要用于存储FPGA的配置程序, SPI通信,8引脚,256Mbit或者512Mbit, 目前我这给客户推荐的型号是:S25FS 512 S AG N F I 01 1 , 您那能否给些建议?谢谢。
The customer is currently selecting NOR Flash for use with Altera FPGA (specific FPGA model: 5CEBA4U15), which is mainly used to store FPGA configuration program, SPI communication, 8-pin, 256Mbit or 512Mbit. Currently, the model I recommend to the client is S25FS 512 S AG N FI 01 1, could you give me some suggestions?thank you

Hi
Is there a "blank check" command for S70FLO1GS product?
If not, what is the simple and fastest way to do "erase verification" after bulk erasing?
thanks

Show LessFLASH: S25FL256S (Uniform 64KB sectors)
Hi,
I was trying to program my QSPI flash memory on my board.
However, it seems that the first 8 bytes in each bank (128Mb) of flash cannot be written.
The 0x00000000~0x00000007 and 0x01000000~0x01000007 always remains as 0xFF after erase, and cannot be programmed again.
Here is what i did:
1. Erase the whole chip using Bulk Erase Command. [Send: 0x60]
2. Perform a blank-check in 0x00000000~0x000000FF and 0x01000000~0x010000FF. [Read back, all the bytes are 0xFF]
3. Program 0x00000000~0x000000FF and 0x01000000~0x010000FF with an increased number serial (0x00~0xFF)
[Send: 0x12 0x00 0x00 x00 0x00 0x00 ... 0xFF]
[Send: 0x12 0x01 0x00 x00 0x00 0x00 ... 0xFF]
4. Read back. (The first 8 bytes cannot be written)
0x00000000~0x0000100F: 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0x08 0x09 0x0A 0x0B ... 0xFD 0xFE 0xFF
0x01000000~0x0100000F: 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0x08 0x09 0x0A 0x0B ... 0xFD 0xFE 0xFF
But when I try other addresses, such as 0x00000100~0x00000200, I can read exactly what I write.
How can I write the first 8 bytes in each bank of S25FL256S ?
THANKS!
Show LessHello, support team.
I have received replacement information for the flash memory (PTN204702A.pdf).
Does "Drop-in replacement" mean there is no performance degradation ?
In the case of S29GL064N90TFI040, can I just refer to the 42002-Migrate_from_GL-N__GL-P_to_GL-S.pdf when replacing it with S29GL064S70TFI040?
Thanks and Regards,
YS

Hello.
I'm looking for a replacement for the Macronix MX25LM51245GXDI00.
Please recommend the product.
I'm reviewing S28HL512TFPBHI010.
Thanks and Regards,
YS
Kindly provide the below details for the product S29GL01GP13TFIV10
1) Maximum Junction Temperature (Max Tj)
2) Operating Junction Temperature (Tj)
3) Junction - to - Ambient Thermal Resistance (Theta - JA)
4) Junction - to - Case Thermal Resistance (Theta - JC)
5) Power Dissipation
