AT17N040-10TQC

Configuration PROMs For FPGAs Overview

The AT17N040-10TQC is a 4-Mbit (4,194,304 x 1-bit) serial EEPROM configurator designed for FPGA configuration. It operates on a 3.3V supply and supports commercial temperature ranges from 0°C to +70°C. The device utilizes a simple serial interface with DATA, CLK, RESET/OE, and CE pins to control the configuration process directly with the FPGA without an external controller. It is housed in a 44-lead Thin Plastic Quad Flat Package (TQFP).

Configuration PROMs For FPGAs Feature Summary

• Designed specifically as a configuration memory for Field Programmable Gate Arrays.
• Features pin compatibility with Xilinx XC17SXXXA and XC17SXXXXL PROMs.
• Supports Master Serial Mode for automatic loading upon power-up.
• Utilizes low-power CMOS EEPROM process technology.

Configuration PROMs For FPGAs Applications

• Configuration of Xilinx Spartan-II FPGAs in Master Serial Mode.
• Configuration of Xilinx Spartan-IIE FPGAs in Master Serial Mode.
• Configuration of Xilinx Spartan XL FPGAs in Master Serial Mode.

Configuration PROMs For FPGAs Procurement Notes

Verify that the component is sourced from authorized channels due to its legacy status. Confirm the package type matches the 44-lead TQFP specification. Ensure the operating environment remains within the commercial temperature range of 0°C to +70°C. Check for end-of-life notices or last-time buy notifications associated with this specific Atmel part number.

Configuration PROMs For FPGAs Selection Notes

Select this component when interfacing with older Xilinx Spartan series FPGAs requiring a direct serial configuration source. It serves as a drop-in replacement for compatible OTP PROMs. Consider the AT17LV040 if industrial temperature ratings (-40°C to +85°C) are required instead of the commercial variant.

Configuration PROMs For FPGAs Part Context

This device belongs to the AT17N series of FPGA Configuration EEPROMs manufactured by Atmel. The series includes densities ranging from 256-Kbit to 4-Mbit. The AT17N040 represents the highest density option in this specific generation, providing sufficient storage for complex FPGA bitstreams.
