EP20K200RC208-3 概述

The Intel (formerly Altera) EP20K200RC208-3 is a member of the APEX 20K family of Field Programmable Gate Arrays (FPGAs) delivering 200,000 system gates in a 208-pin RQFP (Exposed Pad) package. The device integrates 8,320 logic elements and 106,496 bits of embedded memory across the industry's first MultiCore architecture combining look-up table (LUT) logic, product-term logic, and embedded memory blocks on a single die. Fabricated on a 0.22 µm CMOS process, the APEX 20K family supports 1.8 V core operation with LVDS-compatible I/O and a system-level operating frequency up to 167 MHz.

What is an FPGA? A Field Programmable Gate Array is a reconfigurable semiconductor device that allows hardware logic to be programmed after manufacture. The APEX 20K family pioneered system-on-a-programmable-chip (SOPC) integration, embedding up to 1.6 Mbits of RAM directly into the fabric alongside logic and product-term resources, eliminating external SRAM in many designs. This architecture places the EP20K200RC208-3 in a hierarchy of: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit.

The MultiCore architecture combines three specialized structures: LUT-based logic for register-intensive functions, embedded array blocks (EABs) implementing memory or product-term logic, and a high-bandwidth interconnect network. The EP20K200RC208-3 supports up to 144 user I/O pins via LVDS signaling, with four phase-locked loops (PLLs) for clock management. The device supports hot-socketing, in-system programmability via IEEE 1149.1 JTAG, and operates across the industrial temperature range from -40°C to +85°C.

Typical applications include high-speed telecommunications interfaces, PCI bridge logic, DSP co-processing, and custom parallel bus controllers where the embedded memory eliminates the need for external SRAM. The 208-RQFP package provides a thermally enhanced footprint with an exposed pad for thermal dissipation, and the -3 speed grade places this part in the mid-range of APEX 20K performance options.

When designing with the EP20K200RC208-3, engineers should verify that the Quartus development toolchain (versions prior to 9.1) supports the device and that PCB thermal vias are placed under the exposed pad to maintain junction temperature under full I/O loading. Note that the APEX 20K family has reached end-of-life; consider Cyclone II or Cyclone III for new designs, and use this part only for maintenance of existing systems.

This page synthesizes distributor availability, parametric alternatives, and design considerations specific to the APEX 20K family that are not aggregated on any single manufacturer or distributor page, helping engineers evaluate lifecycle risk and replacement strategies.

典型应用

EP20K200RC208-3 适用于 6 应用s: Telecommunications Interface Bridging, PCI Bus Bridge / Embedded Controller, DSP Co-Processor Front-End, Custom Parallel Bus Controller, Avionics Display / Radar Signal Pre-Processing, Test & Measurement Custom Logic.

🌐

Telecommunications Interface Bridging

The EP20K200RC208-3's 200K system gates and 106,496 bits of embedded memory make it well-suited for telecom line-card bridging functions where custom bus protocols must be translated between legacy TDM/E1 interfaces and modern packet backplanes. The MultiCore architecture's product-term logic handles small glue functions that would otherwise require a discrete CPLD, while LUT logic implements the main protocol state machines. The 167 MHz -3 speed grade supports high-speed serializer/deserializer bridging paths. The 208-RQFP with exposed pad allows hand-repairable assembly typical of telecom infrastructure boards.

🖥️

PCI Bus Bridge / Embedded Controller

The EP20K200RC208-3 was widely deployed as a PCI 2.2 bridge controller in industrial single-board computers and custom embedded motherboards. Its 144 user I/O pins accommodate the full 32-bit/33 MHz PCI bus plus auxiliary GPIO, while the 8,320 logic elements implement target/master state machines, configuration space, and DMA engines. The 106 Kbits of embedded memory serve as scratch FIFOs for posted-write buffers. The -3 speed grade meets the 33 MHz PCI timing budget with margin, and the industrial temperature range suits factory automation deployments.

🧩

DSP Co-Processor Front-End

The APEX 20K's embedded array blocks (EABs) can implement RAM-based lookup tables, FIR filter coefficients, or sine/cosine tables, making the EP20K200RC208-3 suitable as a co-processor front-end for fixed-point DSP algorithms. The 106,496 bits of embedded memory map to 16 Kbits × 32 filter taps for dual-channel FIR filtering, and the 4 PLLs provide clock-domain crossing between the host DSP and the FPGA fabric. The 167 MHz fabric speed on the -3 grade sustains real-time sample rates up to 80 MSPS for moderate-complexity DSP pipelines.

🏭

Custom Parallel Bus Controller

Legacy industrial control systems often require custom parallel bus controllers for proprietary backplanes, SRAM/DRAM memory subsystems, or legacy peripheral chips. The EP20K200RC208-3 provides 144 user I/O pins sufficient for 32-bit data plus 24-bit address plus control signals, and the MultiCore architecture's product-term logic simplifies implementation of burst-mode handshakes and wait-state generation. The 208-RQFP package simplifies hand-prototyping and field replacement in existing industrial control cabinets.

✈️

Avionics Display / Radar Signal Pre-Processing

Legacy avionics systems and ground-based radar signal pre-processing units deployed the EP20K200RC208-3 for its radiation-tolerance characteristics and proven reliability profile. The 144 I/O pins accommodate parallel ADC interfaces at sample rates up to 80 MSPS, and the 106 Kbits of embedded memory implement moving-window integrators and CFAR detection. The -3 speed grade meets timing closure for multi-channel radar pre-processing at typical PRFs. Note that for new aerospace designs, rad-hard FPGAs from Microsemi or Xilinx are now preferred.

🔧

Test & Measurement Custom Logic

ATE (automatic test equipment) platforms and bench-top test instruments leverage the EP20K200RC208-3 to implement custom pattern generators, protocol decoders, and timing-edge placement logic. The 167 MHz fabric frequency on the -3 speed grade supports pattern generation at up to 80 MHz with sub-nanosecond resolution. The 8,320 logic elements implement complex state machines for boundary-scan, JTAG, and proprietary test protocols. The 208-RQFP package is friendly to iterative prototype revisions common in test equipment development.

What is the EP20K200RC208-3 FPGA?
The EP20K200RC208-3 is a 200K-gate member of the Intel (formerly Altera) APEX 20K family of FPGAs. It contains 8,320 logic elements, 106,496 bits of embedded memory, and 144 user I/O pins in a 208-pin RQFP with exposed thermal pad. It uses a 0.22 µm CMOS process at 1.8 V core and supports LVDS signaling with a maximum operating frequency of 167 MHz per the APEX 20K datasheet family.
What is the difference between APEX 20K and Cyclone FPGAs?
The APEX 20K (1999-era) uses a MultiCore architecture combining LUT logic, product-term logic, and embedded array blocks, fabricated at 0.22 µm. The Cyclone family (2002 onward) replaced it with a simpler 1.5 V / 1.8 V LUT-only architecture on 0.13 µm process. APEX 20K has reached end-of-life; for new designs, use Cyclone II/III/IV/10. The EP20K200RC208-3 is recommended only for maintenance of legacy systems.

Lead time for the EP20K200RC208-3 as of 2026-09-07 is typically 8–12 weeks when sourced from authorized stocking distributors, due to obsolete lifecycle status. Some lots are available immediately in 1–10 piece quantities from broker inventory, but volumes above 100 pieces require special quoting. Plan ahead for production orders.
Is the EP20K200RC208-3 in stock?
As of 2026-09-07, the EP20K200RC208-3 has limited stock at authorized distributors including Rochester Electronics. Open-market brokers may carry small quantities. Stock is constrained due to obsolete lifecycle status; verify current availability via Octopart or contact distributors directly for confirmed quantities and lead times on this Intel APEX 20K device.
EP20K200RC208-3 vs EP20K200RC208-1 — which is better for my design?
The EP20K200RC208-3 is the -3 speed grade (faster, ~167 MHz) while the EP20K200RC208-1 is the -1 speed grade (slower, ~133 MHz). Both share identical 208-RQFP pinout and the same 200K-gate die. Choose the -3 for performance-critical paths; choose the -1 if power budget is tight, as faster speed grades consume marginally more quiescent current.
What is the best drop-in replacement for EP20K200RC208-3?
The EP20K200FC484-3 and EP20K200EQC240-3 are not drop-in pin-compatible due to different packages (484-FBGA and 240-RQFP respectively). True drop-in alternatives sharing the 208-RQFP package are EP20K200RC208-1 (slower speed grade) and EP20K200RC208-2 (mid speed grade). All three share identical 208-RQFP pinout per the APEX 20K datasheet family, making them PCB-compatible at different performance tiers.
When should I choose EP20K200RC208-3 over Cyclone II EP2C20?
Choose the EP20K200RC208-3 only when maintaining an existing APEX 20K board design where compatibility with the legacy toolchain (Quartus 9.0 or earlier) and the MultiCore architecture's product-term logic is required. For new designs, the Cyclone II EP2C20 in 240-PQFP offers lower cost, lower power, and active lifecycle support. The APEX 20K is obsolete as of 2026-09-07.
Where to download EP20K200RC208-3 datasheet PDF?
The APEX 20K family datasheet (covering EP20K200RC208-3) is available from Intel's legacy document archive at https://www.altera.com/literature/ds/apex20k.pdf, hosted as part of Altera's pre-acquisition documentation. Third-party distributors including Chipdig also host archived copies. The datasheet covers all speed grades (-1, -2, -3) and all package variants in the family.
Where to find EP20K200RC208-3 pinout?
The 208-RQFP pinout for the EP20K200RC208-3 is published in the APEX 20K datasheet family document (Chapter 7: Package Information). The exposed thermal pad on pin 209 must be soldered to a thermal pad on the PCB with adequate via stitching to maintain the industrial -40°C to +85°C operating range.
What are the key specifications of EP20K200RC208-3 that engineers should know?
The EP20K200RC208-3 key specifications: 200,000 system gates, 8,320 logic elements, 106,496 bits of embedded memory, 144 user I/O pins, 4 PLLs, 208-RQFP package with exposed thermal pad, 1.8 V core voltage, 0.22 µm process, 167 MHz maximum frequency, -3 speed grade, industrial -40°C to +85°C temperature range, JTAG/IEEE 1149.1 programming, LVDS I/O support, and hot-socketing capability per the APEX 20K family datasheet.
What is the best Xilinx equivalent for EP20K200RC208-3?
Cross-brand equivalents are difficult to define for the EP20K200RC208-3 because of its obsolete status. The closest Xilinx Virtex-E family equivalent in logic density (~200K system gates) would be the XCV200 in a 240-PQFP package — but note this requires PCB redesign as the XCV200 package differs from the 208-RQFP. Truly pin-compatible Xilinx drop-in parts for the APEX 20K do not exist; cross-brand equivalents typically require PCB rework.
Is the EP20K200RC208-3 obsolete or still active?
The EP20K200RC208-3 is obsolete as of 2026-09-07. The APEX 20K family was discontinued by Altera in 2005 when it was superseded by Cyclone II and Stratix II families. Intel continues to support long-life programs through Rochester Electronics for legacy maintenance, but no new wafer production is occurring. Last-time-buy opportunities may be available for high-volume contracts.

工程参考数据: EP20K200RC208-3 ——对比、设计指导和合规信息。

选型指南

Choose the EP20K200RC208-3 when maintaining a legacy APEX 20K-based board design where the -3 speed grade's 167 MHz fmax is required to meet timing closure, and the 208-RQFP footprint is already committed on the PCB. For new designs or cost-down redesigns of legacy systems, select the EP20K200RC208-1 (lower cost, ~25% slower) or EP20K200RC208-2 (mid-grade) as drop-in 208-RQFP alternatives. For active-lifecycle designs, evaluate Cyclone II EP2C20 (240-PQFP, requires PCB rework) or Cyclone III EP3C10 (144-EQFP, smaller footprint, lower power). All alternatives share the same MultiCore architecture heritage, but only the 208-RQFP APEX 20K 200K family provides direct PCB drop-in compatibility with the EP20K200RC208-3 footprint.

关键差异点

  • Highest speed grade in the 208-RQFP APEX 20K 200K family (对比 EP20K200RC208-1)
  • Pin-compatible upgrade path within the same package (对比 EP20K200FC484-3)
  • MultiCore architecture with product-term logic (对比 Cyclone II EP2C20)

设计说明

The 208-RQFP package features an exposed thermal pad on the underside that MUST be soldered to a copper pour with thermal via stitching to the inner ground plane. Without proper thermal management, junction temperature can exceed 125°C under high I/O toggle activity, derating the industrial temperature range. Recommended: at least 9 thermal vias in a 3x3 grid under the pad, each 0.3 mm diameter, connected to a 1 oz copper inner plane.

The EP20K200RC208-3 requires separate VCCINT (1.8 V core) and VCCIO (3.3 V or 2.5 V I/O) rails with proper decoupling: 0.1 µF ceramic capacitors adjacent to every VCCINT/VCCIO pin pair, plus bulk 10–47 µF tantalum or polymer capacitors on each supply rail. Power sequencing should bring up VCCINT before VCCIO to avoid latchup; consult the APEX 20K datasheet family handbook for the recommended sequence.

Use Quartus 9.0 SP2 or earlier for synthesis, place-and-route, and bitstream generation. Newer Quartus versions do not support the APEX 20K family. Maintain a copy of the legacy MAX+PLUS II software for compatibility with older programming files. JTAG chain ordering must include all other 1149.1 devices on the board; use the Quartus Chain Description File (.cdf) format for programming file generation.

Do not assume new APEX 20K parts are still being manufactured — they have been obsolete since ~2005. All current supply is from remaining wafer stock at Rochester Electronics and authorized aftermarket distributors. Verify lot date codes and request pre-shipment electrical testing for any lot purchased on the open market, as old plastic-packaged parts may have moisture sensitivity issues (MSL) or solderability degradation.
