We have selected the NVRAM CY14X512Q3A suitable for our application but we are not able see the availability anywhere.
The CY14X512Q3A Part number is mentioned in the datasheet of 512-Kbit (64K × 8) SPI nvSRAM.
I could not find any details about CY14X512Q3A from our internal database. Could you please let me know, where did you come to know about the part number CY14X512Q3A?
We recommend you to use our 1 Mbit device CY14V101QS in your application? Please find the datasheet at: http://www.cypress.com/file/178606/download .
Thanks and Regards,
