AT17F040-30CU

Overview

The AT17F040-30CU is a 4-Mbit FPGA configuration memory device manufactured by Atmel. It operates at a supply voltage of 3.3V with 5.0V tolerant I/O pins and supports industrial temperature ranges from -40°C to +85°C. The component utilizes a low-power CMOS FLASH process and features fast serial download speeds up to 33MHz. It is housed in an 8-pad LAP package (6mm x 6mm x 1.04mm) and offers In-System Programmability via a 2-wire bus.

Feature Summary

• In-System Programmable (ISP) capability via a 2-wire serial bus for flexible field updates
• Supports cascading read-back functionality to enable configurations for higher-density arrays or multiple FPGAs
• Provides page download mode allowing storage and retrieval of multiple configuration bitstreams within a single device
• Compatible with various industry-standard SRAM-based FPGA devices including Altera, Xilinx, and Lucent architectures

Applications

• Configuration of Field Programmable Gate Arrays (FPGAs)
• Storage of configuration programs for Altera FLEX and APEX devices
• Configuration support for Xilinx Spartan and Virtex series FPGAs
• Cascaded memory systems for multi-device FPGA configurations

Procurement Notes

Verify the specific ordering suffix 'U' confirms lead-free and halogen-free compliance. Confirm the package designation matches the required 8-pad LAP form factor. Ensure the industrial temperature grade (-40°C to +85°C) aligns with system environmental requirements. Cross-reference the manufacturer documentation for any recent design changes or obsolescence notices.

Selection Notes

Select this component when a cost-effective solution for programming SRAM-based FPGAs is required. Consider its compatibility with existing Master Serial mode interfaces. Evaluate the need for In-System Programmability versus standard parallel programming methods. Assess whether the 4-Mbit density meets the specific bitstream size requirements of the target FPGA array.

Part Context

This device belongs to the AT17F Series of In-System Programmable Configuration PROMs. These configurators are designed to provide simple serial-access procedures for configuring one or more FPGA devices. The series includes variants such as the AT17F080 for higher density applications.

Replacement Considerations

The AT17F080-30CU serves as a higher-density alternative within the same product family. Verify pinout compatibility if substituting between different densities in the AT17F series.
