EPF8636ALI84-4

Field Programmable Gate Array Overview

The Altera EPF8636ALI84-4 is a field-programmable gate array belonging to the FLEX 8000 family. It features 8,000 usable gates, 820 flip-flops, 126 logic array blocks (LABs), and 672 logic elements (LEs). The device supports up to 152 user I/O pins and operates within a voltage range of 4.75 V to 5.25 V. Designed for high-speed applications, it utilizes FastTrack Interconnect for predictable delays and includes dedicated carry and cascade chains for arithmetic functions. The component is housed in an 84-pin PLCC package.

Field Programmable Gate Array Feature Summary

• FLEX 8000 architecture with 8,000 usable gates and 126 LABs
• FastTrack Interconnect providing continuous routing channels
• MultiVolt I/O interface compatible with 5.0-V and 3.3-V logic levels
• In-circuit reconfigurability via external configuration devices

Field Programmable Gate Array Applications

• Bus interfaces integrating multiple 32-bit buses
• Digital signal processing and wide-data-path manipulation
• High-speed controllers and coprocessor functions
• TTL integration tasks

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' against official documentation to confirm industrial temperature rating (-40°C to +85°C) versus commercial grade (0°C to +70°C). Confirm package type matches the 84-pin PLCC variant listed in Table 2. Check RoHS compliance status as older FLEX 8000 variants may not meet current standards.

Field Programmable Gate Array Selection Notes

Select this model when designs require fine-grained logic with high register counts and predictable interconnect delays. Ensure the design fits within 672 LEs and 820 flip-flops. Verify that the system power supply aligns with the 5.0 V core requirement and that I/O levels match the MultiVolt capability.

Field Programmable Gate Array Part Context

This component is part of the Altera FLEX 8000 series, which combines FPGA flexibility with EPLD speed. The family uses CMOS SRAM technology and is supported by the MAX+PLUS II development system. It offers in-circuit reconfigurability and JTAG boundary-scan test circuitry on selected devices.

Field Programmable Gate Array Replacement Considerations

Direct replacements within the same package and pinout are limited due to the legacy nature of the FLEX 8000 family. Consider upgrading to newer Altera/Intel FPGA families such as Cyclone or Stratix, though these require significant redesign of logic and pin assignments.
