EPF8452ATC100-4

Field Programmable Gate Array Overview

The EPF8452ATC100-4 is a Field Programmable Gate Array (FPGA) belonging to the Altera FLEX 8000 family. It features 336 Logic Elements (LEs), 42 Logic Array Blocks (LABs), and 452 registers. The device supports up to 68 user I/O pins and operates within a supply voltage range of 4.75 V to 5.25 V. It utilizes a FastTrack Interconnect for predictable routing delays and includes built-in JTAG boundary-scan test circuitry compliant with IEEE Std. 1149.1-1990. The component is housed in an 84-pin Plastic J-lead Chip Carrier (PLCC) package.

Field Programmable Gate Array Feature Summary

• Contains 336 Logic Elements organized into 42 Logic Array Blocks with 4-input Look-Up Tables and programmable registers.
• Supports MultiVolt I/O interface allowing compatibility with both 5.0-V and 3.3-V logic levels while the core runs at 5.0 V.
• Includes dedicated carry and cascade chains for high-speed arithmetic functions and wide fan-in logic implementation.
• Features In-Circuit Reconfigurability (ICR) enabling real-time system changes via external configuration devices or controllers.

Field Programmable Gate Array Applications

• Bus interfaces integrating multiple 32-bit buses
• Digital signal processing (DSP) and data transformation
• TTL integration and coprocessor functions
• High-speed controllers

Field Programmable Gate Array Procurement Notes

This component is identified as an End-of-Life (EOL) product with discontinued manufacturing status. Verification of availability requires checking secondary market distributors, as standard supply channels no longer stock this item. Compliance with RoHS standards is not indicated for this specific part number.

Field Programmable Gate Array Selection Notes

Select this device when fine-grained architecture and high register counts are required alongside EPLD-like speed characteristics. Ensure the design accommodates the 5.0 V core voltage requirement. Verify that the 84-pin PLCC package fits the PCB layout constraints, noting that alternative packages like TQFP exist for other variants in the same logic density class.

Field Programmable Gate Array Part Context

The EPF8452A variant represents the 4,000 usable gate tier within the FLEX 8000 series. It shares architectural features such as the FastTrack Interconnect and LAB structure with higher-density models like the EPF8636A and EPF8820A, but offers fewer I/O pins and logic resources suitable for mid-range complexity applications.

Field Programmable Gate Array Replacement Considerations

No direct public substitute part numbers are confirmed for this specific legacy component. Migration to modern FPGA families requires redesigning the logic architecture and I/O constraints due to differences in process technology and pinout configurations.
