AT17N512-10SI

Configuration PROMs For FPGAs Overview

The AT17N512-10SI is a 512-Kbit serial EEPROM designed for FPGA configuration. It operates at 3.3V (±10%) with an industrial temperature range of -40°C to +85°C. The device uses a simple serial interface compatible with Xilinx Spartan-II, Spartan-IIE, and Spartan XL FPGAs in Master Serial Mode. It features low-power standby mode, high reliability with 20-year data retention, and is housed in a 20-lead SOIC package.

Configuration PROMs For FPGAs Procurement Notes

Verify the component manufacturer, as the AT17N series was originally produced by Atmel Corporation before its acquisition by Microchip Technology. Confirm that the specific part number matches the industrial temperature grade (-40°C to +85°C) and the 20-lead SOIC package type required for your design. Ensure compatibility with existing FPGA configuration logic.

Configuration PROMs For FPGAs Selection Notes

Select this component when designing systems using Xilinx Spartan-series FPGAs requiring serial configuration. It serves as a direct replacement for older OTP PROMs. Consider the AT17LV512-10SI as a modern alternative if new designs are permitted, as the AT17N series is marked Not Recommended For New Design.

Configuration PROMs For FPGAs Part Context

The AT17N512-10SI belongs to the AT17N series of FPGA Configuration EEPROMs (Configurators). This series provides cost-effective storage for FPGA configuration programs. The AT17N512 specifically offers 512-Kbit capacity, suitable for medium-complexity Spartan-family devices. It interfaces directly with FPGA control signals without requiring an external controller.

Configuration PROMs For FPGAs Replacement Considerations

The AT17N512-10SI is replaced by the AT17LV512-10SI. Both parts share similar functionality but may differ in voltage specifications or manufacturing origin. Verify pinout and electrical characteristics before substitution.
