MPN: EP20K1000CB652C7NJ ✗ Cuối đờiEP20K1000CB652C7NJ Tóm tắt
A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to perform a wide range of digital logic functions. FPGAs sit hierarchically within programmable logic devices (PLDs), which themselves belong to the broader digital IC and ASIC-replacement category. Modern FPGAs combine configurable logic blocks (CLBs), programmable interconnect, embedded memory, multipliers/DSP slices, and high-speed transceivers, enabling hardware-level parallelism far beyond what general-purpose microcontrollers or DSPs can achieve at comparable cost for a given workload.
Key features of the EP20K1000CB652C7NJ include 488 user I/O pins, 327,680 bits of embedded memory, four phase-locked loops (PLLs) for clock management, MultiCore embedded memory architecture, and pin compatibility with the APEX 20KE family for design reuse. The 652-pin FCBGA package supports high-density board designs with controlled-impedance signal integrity for parallel and serial high-speed interfaces.
Architecturally, the APEX 20KC combines LUT-based logic with embedded system blocks that can each implement dual-port RAM, ROM, or content-addressable memory. The 0.15-micron copper interconnect reduces propagation delay and dynamic power versus the aluminum-process APEX 20K, while remaining pin-compatible so existing 20KE boards accept the 20KC device without re-layout.
Typical applications include high-speed telecom backplanes, parallel DSP pipelines, ASIC prototyping, industrial imaging and video processing, and military/aerospace signal processing. The 488 I/O and abundant internal memory also make this part suitable for legacy system sustainment and form-fit-function replacement programs.
When designing with this part, engineers must plan for the 1.8V core supply and provide adequate decoupling around the BGA footprint. JTAG configuration via the ByteBlaster or MasterBlaster cable is supported, but Quartus II software (legacy Altera IDE) is required for synthesis, place-and-route, and bitstream generation.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes beyond the manufacturer datasheet summary, helping procurement and engineering teams evaluate the EP20K1000CB652C7NJ for both new designs and legacy sustainment programs.

Ứng dụng tiêu biểu
EP20K1000CB652C7NJ phù hợp cho 6 Áp dụngs: Telecom Backplane Aggregation, ASIC Prototyping, Industrial Imaging and Video Processing, Military/Aerospace Signal Processing, Legacy Sustainment and Form-Fit-Function Replacement, Digital Signal Processing (DSP) Datapath Implementation.
Telecom Backplane Aggregation
The EP20K1000CB652C7NJ's 488 user I/O pins and 1,000,000 system gates make it well-suited for high-density telecom backplane aggregation fabrics where parallel LVDS or HSTL buses aggregate multiple lower-speed serial links. With 327,680 bits of embedded memory it can buffer packet payloads on-chip, eliminating external SRAM. The 652-pin FCBGA package supports the controlled-impedance routing required for 100 MHz+ parallel backplane operation, while the 4 PLLs provide multiple clock domains needed for system-side and line-side synchronization.

ASIC Prototyping
With 38,400 logic elements and 1 million system gates, the EP20K1000CB652C7NJ can emulate mid-complexity ASIC designs (typical gate-equivalent of 500-800K ASIC gates) for pre-silicon validation. Its MultiCore architecture combining LUTs with embedded system blocks allows accurate modeling of SRAM/ROM macros alongside random logic. Engineers can iterate RTL in Quartus II, perform real-time at-speed verification, and debug with SignalTap embedded logic analyzer, reducing tape-out risk for the target ASIC.
Được đề xuất
Industrial Imaging and Video Processing
The device's 488 I/O and abundant internal memory make it effective for parallel pixel processing pipelines in machine vision and broadcast video equipment. Embedded system blocks can implement line buffers and frame buffers, while LUT-based datapaths perform real-time pixel transforms, color space conversion, and edge detection at video rates up to 375.94 MHz. The FCBGA package provides the thermal headroom and signal integrity needed for sustained parallel video throughput in factory-floor imaging systems.
Được đề xuất
Military/Aerospace Signal Processing
The APEX 20KC's mature copper-interconnect process and documented reliability make it a candidate for legacy defense and aerospace systems where re-qualification cost outweighs the benefits of migrating to newer families. The device's deterministic LUT-based architecture is well understood for safety-critical DSP functions such as radar pulse compression, beamforming, and EW signal generation. For new military designs, however, consult DSCC-qualified parts or move to a current radiation-tolerant family such as Microsemi/RTAX.
Được đề xuất
Legacy Sustainment and Form-Fit-Function Replacement
The EP20K1000CB652C7NJ is most commonly sourced today for legacy system sustainment programs - aircraft, ships, and industrial control systems originally designed around APEX 20K/KE/KC where the PCB and firmware must remain unchanged. Authorized obsolete-stock distributors (Rochester Electronics, legacy Altera distributors) maintain franchised inventory with full traceability and original test programs. Engineers performing FFF replacement should verify the date code, lot traceability, and counterfeit-mitigation documentation before integration.
Được đề xuất
Digital Signal Processing (DSP) Datapath Implementation
The 20KC's embedded system blocks can implement multiplier-accumulators, FIR filters, and FFT butterflies when configured with arithmetic mode, enabling DSP datapaths in the 100-300 MHz range without external DSP chips. For SDR baseband processing, channelization, or software-defined radio modems, the EP20K1000CB652C7NJ provides a balance of logic and memory for moderate-complexity algorithms. For higher DSP throughput, migrate to Stratix II/III/IV with dedicated DSP blocks.

Ghi chú thiết kế
The 652-pin FCBGA package requires a multi-layer PCB (typically 6-8 layers minimum) with microvia or via-in-pad technology for reliable BGA assembly. Use a 1.0 mm ball pitch (or 1.27 mm for the older FineLine variant) and follow Altera's recommended land pattern and solder paste stencil. Decouple each VCCINT/VCCIO pin with a 0.1uF X7R ceramic placed as close as physically possible to the ball, plus bulk 10-47uF tantalum or polymer capacitors on each supply plane.
Do not confuse the 'CB652' package suffix (652-pin FCBGA, 1.27 mm pitch FineLine) with the later 'CB652C7N' form. The trailing 'J' suffix in 'C7NJ' indicates an extended temperature or screening option that must be verified against the device datasheet before substituting. Always confirm the full MPN including all suffix characters match the original Altera datasheet order code when sourcing obsolete stock.
Differential pairs (LVDS, PECL) should be length-matched within 50 mils for 100 MHz operation and within 20 mils for 200+ MHz. Route each LVDS pair on a single inner layer with continuous ground plane reference, and avoid routing over power plane splits. The 4 PLLs each require their own quiet analog VCC plane (VCC_PLL) decoupled with a Pi filter (ferrite bead + 0.1uF + 10uF) to minimize jitter.
