SRAM Forum Discussions

Hi,

I am using CY62177EV30LL in one of our applications and we would like to use two of these chips for increased memory.

In terms of layout, I am thinking, can we place one on the top layer and one on the bottom layer? We would swap the address and data lines (so that we can connect them through same vias), but because access is random, it should not matter, right?

I am attaching my proposed schematic. Only exception would be I/O11 and I/O15, which cannot be mirrored.

Has anyone here done that and would any of you be able to suggest if there should be any concerns.

Thanks,

AQ

Hi all,

Using the memory CY7C1470BV25-167BZXI, I'm looking for some information about the SEU and MBU rate of the memory CY7C1470BV25-167BZXI.

I found a little bit, maybe not at the right place but I did not found any info on the subject. If someone as some data about either test result, cross section, ... I would be interested.

Thanks by advance,

Romain

Hello everybody.

Recently, I made a mistake by buying the AMD RADEON R9 Gamer Series [R9S48G2806U2S] RAM. The bottom line is that various software, like Thaiphoon, cannot determine the memory chips that are in this RAM. I wrote to AMD asking for help. Here is what they answered:

Please note AMD abandoned flash memory business more than a decade ago. This business unit was spun off named SPANSION, which eventually took over by CYPRESS SEMICONDUCTORS.

I request you to please reach out to Cypress Semiconductor customer support for further assistance. Please visit https://www.cypress.com/contact-us

Thanks for contacting AMD.

Actually, I wrote Cypress, where AMD sent me.

Cypress, in turn, sent me here to the forum. So I ended up here. Apparently, those who are sitting in customer support are too lazy to spend 15 minutes and look at the specifications in the archive (the more manufacturers of this memory tried to erase meta data). By the way, I thought that sending from office to office and a similar bureaucracy is a trait inherent in Russia, but as it turned out, everyone is sick of it

Please, if you know which chips are used here, let me know. It is important for me for my professional activity.

Thanks in advance.

Hello,

What is, or where can I find the MTBF/FIT or component lambda value for component CY7C1041DV33-10ZSXI?

Thanks for answer.

Hi CY Friend，

If I need 6 ASYNC SRAM connect with one chip, how to connect these srams? main chip is nxp 5777c, it has EBI interface.

Hi all,

I am searching alternate part of CY7C1041CV33-12ZXC.

Is CY7C1041G30-10ZSXI pin compatible?

Is there any functional difference between CY7C1041CV33-12ZXC and CY7C1041G30-10ZSXI?

我有一个开发板，使用的CY7C1338G，准备用CY7C1441或CY7C1481替代，CY7C1441或CY7C1481只是多了几根地址线，而CY7C1338并没有使用这几个引脚，另外，CY7C1441或CY7C1481的DQP1~4如果不使用，需要怎么处理，最终能够实现板子对这三个芯片都兼容呢？

1. CY7C1360C-166BZI is obsolete and it was operating in -40 to 85 which is the most common application we use. According to your website, the CY7C1360C-166BZC is still in production.
2. In 2016 you perform a qualification test for CY7C1360C-166BZC. According to this test, the commercial item wend through the same test as the industrial item. Is this correct ?
3. Can you advise what are the risk of using the commercial item in -40 to 85 ?
