SRAM Forum Discussions

Hello,

We are using Async SRAM "CY7C1021DV33-10ZSXI" from cypress.

As per datasheet and other design guideline document from cypress, there is no length matching requirements listed.

but as it is a parallel bus, we believe there should be length matching requirements for these Address and control group and data group.

so, let us know the length matching requirements for the Async SRAMs.

Thanks and Regards

Can I ask whether there are plans to build 5V compliant I2C SOIC8 FRAM devices with a greater capacity than 8k bytes please ?

Hi,

I need to use CY7C09269V-12AXC in one of my design. Unfortunately found its obsolete now. Please help me to find a compatible alternative for that.

Hi all,

I want to know the differences between "CY7C1061G30-10BVJXI" and "CY7C1061G30-10BV1XI" (J or 1) ?

Are all below ordering codes drop in replacement for CY7C1061G30-10BVJXI ?

CY7C1061G30-10BV1XI

CY7C1061GE30-10BV1XI

CY7C1061GE30-10BVJXI

Thank's in advance,

Best Regards

I'm interested in the SRAM CY7C1071DV33 memory, but we need a temperature range of -55ºC to 125ºC. Does this option exist?

Dear Cypress,

I am checking the CY7S1061GE30 that is entered into Custom B/D with TI hercules rm48x.

In order to use this SRAM, I need to set correct values into EMIF register.

Below captured screen is TI Halcogen HMI which generates HAL(Hardware Abstraction Layer) code.

I'm trying to find below values (ASYNC1 Timings : W_SETUP, W_STROBE, W_HOLD, R_SETUP, R_STROBE, R_HOLD).

The clock is set as 100 MHz now. so I assume that 1 cycle is 10 ns.

Even though, I've checked AC switching Characteristics of your datasheet,

I didn't catch which value is correct for  below setting.

Because all values of AC switching Characteristics are less than 10 ns.

So it seems that below values are filled as 0 or 1.

For your reference, Let me attached EMIF document.

Could you kindly guide me how I calculate these?

Thank you.

  Hi, I used CY7B138-35JC  in the design, but it is obsolete now, do you have a replacement for it , which is Pin to Pin and the supply voltage is compatible ? Thank you.

Would it be possible to obtain a memory map (dependency of cells against their positions) of cy7c1061ge30 for radiation test?

Thank you
