Configuration PROMs For FPGAs Procurement Notes

Verify the specific ordering suffix matches the required operating temperature range and voltage specifications. Confirm that the package type aligns with the design footprint requirements. Ensure compatibility with existing programming systems such as industry-standard programmers or the Atmel ATDH2200E Programming System before procurement.

Configuration PROMs For FPGAs Selection Notes

Select this component when a 2-megabit capacity is sufficient for the target FPGA configuration needs. Choose the LV variant specifically for 3.3V logic environments. Consider the PLCC package availability if redesigning existing hardware. Evaluate the need for cascading capabilities if larger configuration arrays are anticipated in future iterations.

Configuration PROMs For FPGAs Part Context

This part belongs to the high-density AT17 Series of FPGA Configuration EEPROMs. The series provides cost-effective memory solutions for configuring SRAM-based FPGAs.
