EP1800GM-75/B

Overview

The EP1800GM-75/B is a high-performance Field Programmable Gate Array (FPGA) from the Altera FLEX 10K family, manufactured by Rochester Electronics. It features 24,000 system gates and supports up to 360 user I/O pins within a 324-pin Plastic Ball Grid Array (PBGA) package. The device operates at a maximum frequency of 75 MHz with a supply voltage range of 2.3V to 2.7V. Key internal resources include 16 embedded EABs (Embedded Array Blocks), 1,094,400 total bits of RAM, and support for complex logic applications requiring high density and flexible interconnectivity.

Feature Summary

• Supports complex digital logic designs through a dense array of Embedded Array Blocks (EABs).
• Features a highly flexible global routing architecture enabling efficient signal distribution across the chip.
• Includes on-chip memory blocks suitable for data buffering and storage applications.
• Provides extensive I/O capabilities with configurable standards for diverse interface requirements.

Applications

• Industrial automation control systems
• Telecommunications infrastructure equipment
• Test and measurement instrumentation
• Military and aerospace avionics subsystems

Procurement Notes

Verify the specific revision code and date code upon receipt, as legacy components may vary in manufacturing lot. Confirm that the PBGA package condition meets your thermal and mechanical handling requirements. Ensure compatibility with your existing programming and configuration tools, as older FPGA families may require specific software versions for bitstream generation and download.

Selection Notes

Select this component when a design requires moderate logic density with significant embedded memory resources. It is suitable for applications needing reliable performance in harsh environments due to its military-grade availability. Consider the 75 MHz speed grade if timing constraints are moderate. Evaluate the PBGA footprint against your PCB layout constraints and reflow soldering profiles.

Part Context

This part belongs to the Altera FLEX 10K family, a foundational line of FPGAs known for introducing embedded array blocks and fast interconnects. Rochester Electronics provides lifecycle support for these legacy devices, ensuring continuity for long-term industrial and defense products. The 'B' suffix typically denotes a lead-free or specific environmental compliance variant within the manufacturer's historical coding structure.

Replacement Considerations

Direct pin-to-pin replacements are limited due to the proprietary architecture of the FLEX 10K series. Functional equivalents may exist in the FLEX 10KE or APEX families, but these often require schematic redesign and bitstream recompilation. Verify logical equivalence and timing closure before substituting with any other FPGA family.
