Nor Flash Forum Discussions

Hi,

Cypress S25HL512TDP Semper Flash with Quad SPI - Flash Memory is used.

Registers are Configured for below settings

• 4 Byte Addressing
• Single Data Transfer Rate 
• Quad I/O Mode
• Uniform Address Spacing
• Page Size 256Bytes/512Bytes

After Register Write, We need to Read/Write memory in Burst mode.Page program is performed for 512 bytes

Do We have to set "Program Enable" after each Page Program operation?

 Please provide sequence of operation to perform Burst Read/Write .

Hello,

I am currently simulating with the bus functional model for the S25FL512S memory part.

Is a sector or bulk erase (SE/BE) required prior to a page program (PP), in simulation?

Page 67 of the datasheet (https://www.cypress.com/file/177971/download) says, "The Sector Erase (SE) and Bulk Erase (BE) commands set all the bits in a sector or the entire memory array to 1. A bit needs to be first erased to 1 before programming can change it to a 0. While bits can be individually programmed from a 1 to 0, erasing bits from 0 to 1 must be done on a sector-wide (SE) or array-wide (BE) level."

It would seem that the an erase *is* required for the actual part, but I'm not sure how realistic the model is compared to the actual part. When we attempt to page program, we are seeing all 1's upon return. We are issuing WREN prior to every PP command.

Please advise, thanks.

Hello

Please tell me about S25FL512.

1) Can I use FLASH of S25FL512DS * as SDR ?

If possible, is the maximum frequency of SDR 80MHz ? Is it 133MHz?

2) Can I use FLASH of S25FL512AG * as DDR ?

If possible, is the maximum frequency of DDR 80MHz ? Is it 66MHz?

best regards

hello:

 I have register as memeber of cypress but still can not download the following

One week ago, I registered to the Semper Access Program (SAP).

But, I do not received invitation in my community e-mail inbox.

Do I need to set anything in my community e-mail?

Hi Team,

In my application, I am using S25FL256SAGMFI000 SPI-based NOR flash chip. I am able to establish the communication with it successfully and able to enable the dynamic protection scheme as well. But, additionally, I am looking forward to understanding the ECC protection for this chip. Is ECC enabled for this chip by default or I need to follow the particular sequence to enable the ECC; I would like to know that sequence if there any.

Also, I am keen to understand that is there any method possible with which we can verify that ECC is detecting the error properly.

Request you to provide me support in understanding this ECC-related question for this chip. Quick support will be appreciated.

Regards,

Shivam

I couldn't able to find the footprint recommendation for S25HS512TFANHI010. Is there any specific place on cypress.com where I could find the recommended PCB pattern & layout guidelines?
