AT17F080A-30JU

Overview

The AT17F080A-30JU 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, while maintaining a 10MHz operational limit. The device utilizes a low-power CMOS Flash process and features In-System Programmability via a 2-wire bus. It is housed in a 20-lead PLCC package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Supports In-System Programming through a simple 2-wire serial interface
• Provides direct compatibility with Altera FLEX, Excalibur, Stratix, Cyclone, and APEX devices
• Enables cascading configurations for higher-density arrays or multiple FPGA setups
• Includes page download mode capability for storing multiple bitstreams within a single device

Applications

• Configuration of Altera SRAM-based FPGAs
• In-System Programming of programmable logic devices
• Cascaded FPGA array configuration systems
• Industrial embedded system reconfiguration

Procurement Notes

Verify component authenticity against official Microchip/Atmel documentation due to the discontinued status of this specific part number. Confirm that the 20-lead PLCC package matches the target PCB footprint requirements. Ensure programming equipment supports the required 2-wire serial protocol for ISP operations. Check for RoHS compliance markers on physical units if environmental regulations apply to the final assembly.

Selection Notes

Select this component when designing systems requiring non-volatile storage for FPGA configuration data without external microcontrollers. It is suitable for applications needing 5.0V tolerant interfaces despite a 3.3V core supply. Consider its endurance rating and power consumption characteristics relative to system standby requirements. Verify that the available package options align with manufacturing constraints.

Part Context

This device belongs to the AT17FxxxA series of configurators, originally developed by Atmel Corporation before its acquisition by Microchip Technology. The series provides cost-effective solutions for configuring SRAM-based FPGAs using serial access procedures. The AT17F080A variant specifically offers double the density of the AT17F040A model, allowing it to store larger configuration bitstreams.
