EP20K200RC208-3 Обзор
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.

Типичное применение
EP20K200RC208-3 подходит для 6 применениеs: 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.
Рекомендуется
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.
Рекомендуется
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.
Рекомендуется
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.
Рекомендуется
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.
Рекомендуется
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.

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.
Информация о соответствии
RoHS compliance verified via Altera/Intel product documentation. APEX 20K family predates AEC-Q100 qualification programs; consult automotive applications handbook for any new automotive design.
