Configuration PROMs For FPGAs Procurement Notes

Verify the component manufacturer, as the datasheet originates from Atmel Corporation, which was acquired by Microchip Technology. Confirm that the specific ordering code AT17N256-10PC matches the required 8-lead PDIP package and commercial temperature rating. Ensure compatibility with existing FPGA designs before procurement.

Configuration PROMs For FPGAs Selection Notes

Select this component for applications requiring pin compatibility with legacy Xilinx OTP PROMs. It is suitable for commercial environments operating between 0°C and +70°C. Consider the AT17LV256 series if industrial temperature ranges or lower voltage operation are required, as the AT17N series is noted as not recommended for new designs.

Configuration PROMs For FPGAs Part Context

The AT17N256-10PC belongs to the AT17N series of FPGA Configuration EEPROMs. This series provides cost-effective configuration memory solutions for SRAM-based FPGAs. The device utilizes a simple serial-access procedure to configure one or more FPGA devices automatically upon power-up.
