AT17F32A-30BJU

Overview

The AT17F32A-30BJU is a 32-Mbit serial configuration flash memory designed for Field Programmable Gate Arrays (FPGAs). It operates on a single 3.3V supply with 5V tolerant I/O pins and utilizes a simple 2-wire serial interface for in-system programming. The device supports cascading to accommodate higher-density arrays or multiple configurations within a single package, featuring low-power standby modes and compatibility with Altera FPGA devices.

Feature Summary

• Supports In-System Programming via a 2-wire serial bus
• Enables system reconfiguration by storing up to four individual bit stream files
• Allows cascading of multiple devices to support additional configurations or higher-density arrays
• Provides direct interface compatibility with SRAM-based FPGAs

Applications

• Configuration of Altera FLEX, Excalibur, Stratix, Cyclone, and APEX devices
• Cascaded FPGA array configuration systems
• Applications requiring simple system reconfiguration from a single memory device

Procurement Notes

Verify the specific ordering code AT17F32A-30BJU against current manufacturer documentation to confirm availability status. Ensure that the industrial temperature range (-40°C to +85°C) aligns with your operational requirements. Confirm that the 44-lead PLCC package dimensions match your PCB footprint specifications before finalizing procurement.

Selection Notes

Select this component when designing systems requiring non-volatile storage for FPGA configuration data. It is suitable for applications needing 5V tolerant interfaces while operating at 3.3V. Consider its cascading capability if the target FPGA density exceeds the capacity of a single unit or if multiple configuration profiles are required.

Part Context

This part belongs to the AT17FxxA series of In-System Programmable Configuration PROMs. These configurators provide cost-effective memory solutions for establishing I/O and logic functions in SRAM-based FPGAs upon power-up or command. The series is engineered for straightforward integration into master serial mode configurations.
