AT17N256-10SC

Configuration PROMs For FPGAs Overview

The AT17N256-10SC is a 3.3V FPGA Configuration EEPROM providing 256-Kbit of non-volatile memory. Designed for serial access, it interfaces directly with SRAM-based FPGAs to store configuration programs. The device operates within a supply voltage range of 3.0V to 3.6V and supports maximum clock frequencies up to 10 MHz in commercial applications. It utilizes a simple three-wire serial interface (DATA, CLK, CE) controlled by the FPGA during Master Serial Mode loading.

Configuration PROMs For FPGAs Procurement Notes

Verify component authenticity through authorized Microchip or Atmel distributors. Confirm package integrity matches the 20-lead SOIC specification. Ensure the ordering code suffix aligns with required temperature ranges. Check datasheet revision history for any last-time buy notices or obsolescence warnings associated with this specific part number.

Configuration PROMs For FPGAs Selection Notes

Select this component for designs requiring direct compatibility with legacy Xilinx Spartan series FPGAs. Verify that the system power supply remains within the 3.0V to 3.6V operating window. Consider the industrial temperature variant if operation exceeds the commercial range. Evaluate migration paths to the AT17LV series if new design recommendations apply.

Configuration PROMs For FPGAs Part Context

This device belongs to the AT17N series of FPGA Configurators manufactured originally by Atmel Corporation, now under Microchip Technology. These devices are specifically engineered to simplify the configuration process for Field Programmable Gate Arrays by eliminating the need for complex parallel programming interfaces during field updates.

Configuration PROMs For FPGAs Replacement Considerations

Public documentation indicates the AT17N256 is replaced by the AT17LV256. Verify functional equivalence and pin compatibility before substitution.
