Nor Flash Forum Discussions
Hi,
What is the ESD (HBM) rating for below part number
> S29CL016J1JQFM030
Hello all,
I am looking for the timing diagrams for NOR Flash S70GL02GS11FHA010. I looked at the memory link (https://www.cypress.com/part/s70gl02gs11fha010 ) but I couldn't find them.
Is this information available on the website or do I need to contact Cypress directly?
Thank you

Hi,
Customers are considering "S25FL064LAB MFI010" as the boot ROM for the MCU.
The SPI clock output by the MCU is set to 24MHz.
Since the High width / Low width specification of the SPI clock of the MCU is "min.40%", the minimum width is (1/24) x 40% = 16.667ns.
On the other hand, the High width / Low width of the input clock on the NOR Flash side is "min.45%", so it is required 18.75ns.
Q1.
If I use an SPI clock with a frequency of 24MHz and a duty of ± 10% for the S25FL064L, does it work properly?
What happens if there is a problem?
Q2.
Is the duty ratio value "min.45%" of the SPI clock of S25FL064L the same specification regardless of the oscillation frequency?
The maximum input frequency of this NOR Flash is 50MHz. The value of the fluctuation range (50% Psck-5%) for this frequency is considered to have the most severe effect on the NOR Flash setup / hold timing specifications.
Therefore, NOR Flash is designed to meet the timing specifications at 50MHz, so I think that the setup / hold margin is about twice as long as the clock at 24MHz.
Do you agree with my way of thinking?

Show LessHi,
Is there an IBIS model for the CYRS16B512? I'd like to simulate some interfaces with the Microsemi RTG4 to see if I need to add anything.
Thanks,

Show LessOn an existing medical product, we intend to program the S29GL01GS11DHIV10 before reflow soldering.
Can we rely for a long term data retention ?
Are two reflow cycle reducing the floating gate levels and reducing retention time ? (our expectation is 10 years)
Thanks for the help
