Parallel Configuration Memory for Xilinx Spartan6 FPGA

[ImAl_4681896]

Currently I am using Cypress S25FL256S SPI NOR Flash to configure Xilinx Spartan6 FPGA XC6SLX75fgg484. Now I want to use 8bit parallel configuration ROM to minimize the FPGA configuration time. In other words, I am searching alternate of Xilinx XCF32P (32Mb size) configuration ROM. The Xilinx XCF32P configuration rom is available in -40 to +85 deg C and I need parallel configuration memory in +105 deg C.

Could anyone tell me please, do Cypress offer such parallel configuration ROM?

Thanks.

Hi,

I am unclear if the requirement is 32Mb or 32MB (256Mb) parallel NOR.

• If 32Mb, then S29GL032N: https://www.cypress.com/file/202426/download
  • However only available up to +85°C
• If 256Mb, then S29GL256P: https://www.cypress.com/file/219926/download
  • Also only available up to +85°C

If 105°C support if mandatory, then S29GL256S: https://www.cypress.com/file/177976/download

• But, S29GL-S are only available in x16 bit width, not x8. x16 is (I think) supported on Xilinx Spartan 6

If you can only support x8, then S29GL-T can address both x8 and +105°C support: https://www.cypress.com/file/218336/download

• But minimal density available is 512Mb
