AT17F080A-30QC

Overview

The AT17F080A-30QC is an 8-Mbit serial configuration flash memory designed for Field Programmable Gate Arrays (FPGAs). It operates at a supply voltage of 3.3V with 5.0V tolerant I/O pins and supports maximum clock frequencies up to 33MHz during download. The device features In-System Programming via a 2-wire bus, low-power standby mode, and endurance of 100,000 write cycles. It is available in 20-lead PLCC packages.

Feature Summary

• Supports In-System Programming via 2-wire serial bus
• Compatible with Altera FLEX, Excalibur, Stratix, Cyclone, and APEX devices
• Features cascading capability for multi-device configurations
• Includes page download mode for multiple bitstreams

Applications

• Configuration of Altera FLEX series FPGAs
• Configuration of Altera Excalibur series FPGAs
• Configuration of Altera Stratix series FPGAs
• Configuration of Altera Cyclone series FPGAs
• Configuration of Altera APEX series FPGAs

Procurement Notes

Verify the package type matches the required design footprint, as this part number specifically denotes the 20-lead PLCC option. Confirm that the industrial temperature range (-40°C to +85°C) meets system requirements. Ensure programming tools support the 2-wire ISP interface for field updates. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when configuring Altera SRAM-based FPGAs requiring non-volatile storage. It offers direct interface compatibility with FPGA control signals without external controllers. Consider the 20-lead PLCC package for through-hole mounting needs. Verify that the 3.3V operation aligns with the target FPGA's power domain and that the 5.0V tolerant inputs are necessary for interfacing.

Part Context

This device belongs to the AT17FxxxA series of In-System Programmable Configuration PROMs. It serves as a cost-effective solution for storing configuration programs for FPGAs. The series includes variants like the AT17F040A for 4-Mbit capacity. These configurators utilize a simple serial-access procedure to configure one or more FPGA devices automatically upon power-up.
