AT17F080A-30QI

Overview

The AT17F080A-30QI is an 8-Mbit serial configuration memory device 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 input clock frequencies up to 33MHz during configuration. The component utilizes a low-power CMOS Flash process, offering 100,000 write cycle endurance and a standby current of less than 3mA. It is available in a 20-lead PLCC package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports In-System Programming via a 2-wire serial bus interface
• Provides simple direct interface to SRAM-based FPGAs without external controllers
• Enables cascading capabilities for configuring multiple devices or higher-density arrays
• Features page download mode allowing storage of multiple configuration bitstreams

Applications

• Configuration of Altera FLEX, Excalibur, Stratix, Cyclone, and APEX devices
• Configuration of Atmel AT40K and AT94K FPGA families
• Field programmable gate array system initialization
• Cascaded FPGA configuration chains

Procurement Notes

Verify the specific package type against official documentation, as the 'QI' suffix may indicate a variant not explicitly detailed in standard ordering tables. Confirm that the required operating temperature range aligns with the specified industrial limits. Ensure programming tools are compatible with the 2-wire serial protocol. Check for any lifecycle status changes regarding availability.

Selection Notes

Select this component when designing systems requiring non-volatile configuration storage for SRAM-based FPGAs. It is suitable for applications needing direct FPGA control without complex host processors. Consider its compatibility with existing Altera and Atmel device families. Evaluate power consumption requirements against the standby and active modes specified.

Part Context

This device belongs to the AT17FxxxA series of In-System Programmable Configuration PROMs. These configurators provide cost-effective solutions for storing FPGA configuration programs. The series supports both 4-Mbit and 8-Mbit densities, packaged in 8-pad LAP or 20-lead PLCC formats. They emulate Atmel AT24C Serial EEPROMs for simplified integration.
