EP20K400BC652-2AA Overview
An FPGA, or field-programmable gate array, is a semiconductor device whose logic architecture and interconnections are configured after manufacturing. Its hierarchy commonly extends from programmable logic blocks to embedded-memory blocks and general-purpose I/O, then to programmable logic and digital integrated circuits. APEX-20K devices combine programmable logic, memory, and I/O resources for implementing high-density digital systems and custom interface functions.
The principal features of EP20K400BC652-2AA are 1,664 LABs/CLBs, 16,640 logic elements/cells, 212,992 total RAM bits, and 502 I/O. The 652-ball BGA package exposes a large number of user-facing connections, while the 2.375 V to 2.625 V supply range supports a defined legacy operating point. These characteristics suit designs where deterministic custom logic, internal storage, and broad parallel interfacing are required.
The APEX-20K architecture integrates programmable logic-array blocks, routing resources, memory, and I/O structures into one configurable device. Configuration data determines the implemented Boolean functions, state-machine behavior, datapaths, and interface protocols. Engineering evaluation should therefore include configuration-file compatibility, power estimation, timing closure, pin assignment, and board-level signal integrity rather than relying only on nominal cell count.
Typical uses include industrial control logic, telecommunications interface equipment, test and measurement platforms, and legacy digital systems. For example, the 502 I/O can support many parallel control or data lines, while the 212,992 RAM bits can implement buffering, lookup tables, or state-machine storage. The obsolete lifecycle status makes production support and long-term availability important procurement concerns.
Designers should verify the exact manufacturer documentation, configuration flow, speed-grade interpretation, and PCB land pattern before reuse. Because the supplied data does not establish a pin-compatible modern successor, replacement should be treated as a board-level migration rather than an assumed direct substitution.
This product record combines the verified electrical, structural, and lifecycle data with explicit unknowns, sourcing provenance, comparison guidance, and design cautions to support legacy-component assessment. Prices, where requested, are referenced as of 2026-09-08, and current inventory must be confirmed directly with the supplier.

Typical Applications
EP20K400BC652-2AA is suitable for 6 applications: Industrial Control Logic, Telecommunications Interface Equipment, Test and Measurement Platforms, Legacy Digital System Maintenance, Parallel Data Acquisition and Buffering, Custom Protocol Bridge.
Industrial Control Logic
EP20K400BC652-2AA is suitable for industrial control logic when a legacy programmable-logic design already depends on the APEX-20K architecture. Its 1,664 LABs/CLBs and 16,640 logic elements/cells can implement state machines, sequencing engines, protocol controllers, and parallel machine-control functions. The 502 I/O provide substantial capacity for sensors, actuators, interlock signals, and local data buses. The 2.375 V to 2.625 V supply range requires a compatible legacy power design. Because the device is obsolete and its exact timing and configuration-flow data are not in the supplied record, use it primarily for maintaining existing equipment or controlled legacy programs rather than new high-availability automation platforms.
Recommended
Telecommunications Interface Equipment
EP20K400BC652-2AA can serve as programmable logic in telecommunications interface equipment, especially where parallel data processing, custom framing, and protocol adaptation are required. Its 16,640 logic elements/cells and 212,992 RAM bits support datapath control, lookup storage, buffering, and format conversion. The 502 I/O make it useful for equipment that must connect multiple low- to moderate-speed interfaces, although no supported I/O standard or maximum I/O frequency is provided in the verified data. Engineers should confirm bank voltage rules, timing margins, impedance constraints, and configuration behavior from the original documentation. The obsolete status is a material qualification and availability risk for new network infrastructure, where a supported FPGA is generally preferable.
Recommended
Test and Measurement Platforms
EP20K400BC652-2AA is a potential fit for test and measurement platforms that require deterministic control, parallel acquisition sequencing, and programmable signal routing. The device combines 1,664 LABs/CLBs with 16,640 logic elements/cells, allowing implementation of counters, trigger logic, timing generators, encoders, and interface controllers. Its 212,992 RAM bits can support sample buffering or configuration tables, while 502 I/O provide room for instrument buses and front-panel connections. The supplied data does not specify clock limits, I/O standards, thermal resistance, or configuration memory type, so a replacement design cannot rely on the nominal resource counts alone. Treat the part as a legacy maintenance option unless all timing, signal-integrity, and lifecycle requirements are independently verified.
Recommended
Legacy Digital System Maintenance
EP20K400BC652-2AA is most defensibly used for maintaining existing digital systems whose firmware, board layout, and design files were created for the APEX-20K family. The 652-ball BGA package and 502 I/O preserve the original system's broad interface capacity, while 1,664 LABs/CLBs and 16,640 logic elements/cells support replacement of a failed or unavailable programmable-logic device. However, the part is explicitly listed as obsolete, and the supplied data does not verify a drop-in substitute. Procurement should document the exact suffix, date code, package marking, and configuration tool version. If a replacement is required, treat it as a board redesign unless the original pinout, timing, power, and configuration requirements are demonstrated to be identical.
Recommended
Parallel Data Acquisition and Buffering
EP20K400BC652-2AA can be used in parallel data-acquisition systems requiring programmable channel control, format conversion, or local buffering. The 16,640 logic elements/cells can implement acquisition sequencing and error handling, while the 212,992 RAM bits provide storage for intermediate data or lookup information. With 502 I/O, the device can aggregate multiple parallel sources before a downstream processor, assuming the board design uses compatible I/O voltages and signal-integrity practices. The verified record does not establish the number of embedded-memory blocks, supported I/O standards, clock rate, or power consumption. Those unknowns are critical for acquisition accuracy and should be resolved against the original APEX-20K documentation before using the device in a safety- or measurement-critical instrument.
Recommended
Custom Protocol Bridge
EP20K400BC652-2AA is structurally suited to a custom protocol bridge that must translate between parallel buses, stateful control channels, or legacy peripheral interfaces. The 1,664 LABs/CLBs and 16,640 logic elements/cells provide capacity for protocol encoders, decoders, FIFOs, and control state machines, while the 212,992 RAM bits can hold conversion tables or intermediate frames. Its 502 I/O support a broad interface fanout when the PCB can manage the associated routing and signal-integrity demands. The 2.375 V to 2.625 V supply range must be matched exactly to the existing power architecture. Because the verified data does not provide timing, I/O-standard, configuration, or thermal details, this application is best limited to sustaining proven legacy bridges or to designs with a complete compatibility-validation plan.

Design Notes
The verified specification states a 2.375 V to 2.625 V supply range but provides no current, power, or rail-separation data. Do not design a new supply from that range alone. Confirm the original APEX-20K power requirements, configuration sequencing, decoupling network, and permissible tolerances. If a related 652-BGA MPN is considered, check whether its voltage and power requirements match the target; EP20K400BC652-2V, for example, is listed with a different 1.71 V to 1.89 V supply range.
The 652-ball BGA requires a controlled-impedance PCB design, a verified land pattern, and complete escape-routing analysis. The provided results mention a 45 mm by 45 mm supplier device package for a related part, but the target package dimensions and ball map are not established. Before assembly, obtain the original mechanical outline, ball numbering, pin assignments, solder-paste recommendation, and thermal-pad requirements. Do not infer that equal 652-ball counts guarantee equal ball functions or footprint compatibility.
EP20K400BC652-2AA provides 502 I/O, but the supplied data does not specify supported I/O standards, bank voltages, slew rates, termination, or maximum toggle frequency. Preserve the original board's controlled-impedance routing, reference-plane continuity, and termination strategy, then verify every used I/O bank against the device documentation. For a new high-speed interface, calculate timing budgets from the design's actual clocks and loads rather than treating the 502-I/O count as a performance limit.
The most serious procurement risk is treating an obsolete APEX-20K listing as a guaranteed source of new, traceable material. Confirm exact suffix, package, date code, condition, quantity, and quality documentation with the supplier. Also verify legacy software availability before committing to a design: modern toolchains may not support the device, and archived configuration data or licenses may be required. A related MPN is not a drop-in alternative until package, pinout, power, timing, configuration, and I/O compatibility are documented.
Compliance Information
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These values are not inferred.
