5SEE9F45I4N

Overview

The Altera 5SEE9F45I4N is a Stratix V E Field Programmable Gate Array (FPGA) designed for high-performance logic applications. It features 840,000 logic elements and 31,700 Adaptive Logic Modules (ALMs). The device includes 52 Mbit of embedded memory and supports 840 I/Os. It operates at a core voltage of 850 mV within an industrial temperature range of -40°C to +85°C. The component is housed in a 1932-ball FBGA package suitable for surface-mount technology.

Feature Summary

• Stratix V E architecture with 840,000 LEs and 31,700 ALMs
• Integrated 52 Mbit embedded memory capacity
• Industrial temperature rating from -40°C to +85°C
• 840 I/O pins in a 1932-ball FBGA package

Applications

• High-density digital signal processing systems
• Complex control logic for industrial automation
• Telecommunications infrastructure hardware
• Test and measurement equipment prototyping

Procurement Notes

Verify the specific suffix 'I4N' against official Intel/Altera documentation to confirm pinout and electrical characteristics, as suffixes often denote temperature grade or packaging variations. Confirm current lifecycle status, as this part may be discontinued or subject to limited supply constraints. Ensure compatibility with existing PCB footprints and thermal management solutions before procurement.

Selection Notes

Select this model when requiring a balance of moderate logic density and low power consumption compared to higher-end Stratix V variants. Compare against the 5SEE9F45C4N if commercial temperature range suffices, or the 5SEEB series if higher logic counts are needed. Verify that the 840 I/O count meets interface requirements without excessive pin multiplexing.

Part Context

This component belongs to the Stratix V E family, which targets cost-sensitive applications requiring significant programmability. It shares the same die and basic specifications as other 5SEE9 variants but differs in environmental ratings and packaging options defined by its suffix. It serves as a mid-range solution within the broader Stratix portfolio.

Replacement Considerations

Direct replacements include other 5SEE9F45 variants such as 5SEE9F45I3LN or 5SEE9F45C4N, depending on required temperature range and availability. Cross-family migration to Agilex or Cyclone V may require schematic and firmware redesign due to architectural differences.
