EP20K60EQC208-3 Présentation
An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit whose logic fabric, interconnect, and I/O behavior are defined by user-programmed configuration data rather than fixed mask geometry. Within the broader taxonomy of programmable logic devices (PLDs), FPGAs sit above simple CPLDs in density and complexity, supporting full system-on-chip (SoC) integration, high-speed parallel processing, and large embedded memory. The APEX 20KE family introduced MultiCore™ architecture to merge LUT-based and product-term-based logic elements on one fabric, enabling designers to choose the optimal logic primitive for each block of a design.
The EP20K60EQC208-3 supports a maximum internal frequency of 160 MHz, with propagation delays around 1.72 ns and a speed grade of -3, making it suitable for high-performance glue logic, bus interfaces, and datapath acceleration in telecom, industrial, and military-aerospace systems. The device offers 32768 bits of embedded SRAM, dedicated high-speed I/O banks, and supports LVTTL, LVCMOS, PCI, and other common interface standards through programmable I/O standards.
Typical applications for the EP20K60EQC208-3 include telecommunications line cards, ASIC prototyping, DSP front-end co-processing, high-speed bridge and protocol conversion, and industrial control. Designers also use this part for legacy system upgrades where 5V-tolerant or 3.3V PCI I/O is required, and where the 208-pin PQFP footprint allows through-hole-friendly PCB assembly for rugged environments.
When designing with the EP20K60EQC208-3, ensure proper decoupling with 0.1 µF and 10 µF capacitors placed close to each supply pin, and follow Altera's Quartus / MAX+PLUS II configuration guidelines for JTAG or passive serial configuration modes. Note that the part is mature and may be subject to last-time-buy notices; verify current lifecycle status with authorized distributors before committing to new designs.

Applications typiques
EP20K60EQC208-3 convient pour 7 applications: Telecommunications Line Cards, ASIC Prototyping and Emulation, Industrial Control and Factory Automation, DSP Front-End Co-Processing, Legacy PCI Bus Interface Bridges, Military and Aerospace Avionics (Legacy), Test and Measurement Instrumentation.
Telecommunications Line Cards
The EP20K60EQC208-3 fits telecommunications line cards where 60K gates of MultiCore™ logic provide glue logic, framing, and protocol handling between physical-layer transceivers and network processors. Its 160 MHz maximum internal frequency and 1.72 ns propagation delay support TDM bus glue, HDLC controllers, and STS-1/STM-0 framer interfaces. The 148 user I/Os accommodate multi-port serial links, while the 32 Kbit embedded SRAM buffers packet payloads. Placed near line interface units, the part consolidates discrete TTL/MSI logic into one programmable device. Design tip: use the JTAG boundary-scan chain for in-system fault isolation across the multi-port backplane.
Recommandé
ASIC Prototyping and Emulation
The EP20K60EQC208-3 serves as an ASIC prototyping vehicle for designs in the 30K-80K gate complexity range, allowing engineers to validate RTL before committing to mask geometry. Its MultiCore™ architecture combining LUT and product-term logic mirrors many ASIC cell libraries, easing port of synthesized netlists. The 32 Kbit embedded SRAM and 148 user I/Os map cleanly to typical ASIC pin and memory profiles. Designers use multiple EP20K60E devices in parallel on prototyping boards to emulate million-gate ASICs. Performance caveat: Fmax at 160 MHz is below modern ASIC speeds, so critical paths may need clock-stretching during validation.
Recommandé
Industrial Control and Factory Automation
The EP20K60EQC208-3 is well suited for industrial controllers where 60K gates implement motor control state machines, encoder interfaces, deterministic EtherCAT or PROFIBUS slave logic, and safety interlocks. Its 0°C to +85°C commercial operating temperature covers most factory-floor enclosures. The 208-pin PQFP package is rugged and field-repairable compared to fine-pitch BGAs in vibration-prone cabinet environments. With 148 I/Os, the FPGA aggregates multiple discrete PLC I/O cards. Design note: external watchdog and brown-out supervisor are mandatory since the APEX 20KE family does not include them on-die.
Recommandé
DSP Front-End Co-Processing
The EP20K60EQC208-3 complements a host DSP by handling high-speed data acquisition, FIR filter pre-processing, FFT butterflies, and DMA engine handshake logic. Its 32 Kbit embedded SRAM can be partitioned into dual-port buffers for ping-pong data streams at sample rates up to 80 MHz, offloading the DSP for higher-level algorithms. The 1.8 V core with 3.3 V tolerant I/Os interfaces cleanly to legacy TMS320 and ADI SHARC DSPs. Performance gain: parallel FIR structures in the FPGA can reduce host DSP MIPS by 30-50% in radar and medical-imaging pipelines.
Recommandé
Legacy PCI Bus Interface Bridges
The EP20K60EQC208-3 implements PCI 2.2 target or master bridges between legacy ISA, VME, and PCI buses in industrial PCs and test equipment. Its 3.3 V PCI-compliant I/O bank supports 33 MHz PCI with the 148 I/Os providing ample address and data bus width. The 32 Kbit embedded SRAM serves as a posted-write buffer and read-prefetch cache. Many aerospace and defense integrators use APEX-20KE devices to add PCI Express compatibility to legacy VMEbus designs. Trade-off: the part supports PCI only, not PCIe; for PCIe, a modern Cyclone or Arria device is required.
Recommandé
Military and Aerospace Avionics (Legacy)
The EP20K60EQC208-3 in its industrial temperature range remains in service in legacy avionics, mission computers, and ground radar signal-conditioning subsystems. With 60K gates and 32 Kbit embedded SRAM, it handles MIL-STD-1553 bus monitor logic, ARINC 429 protocol termination, and discrete-to-network aggregation. The 208-pin PQFP package is preferred in mil-aero designs where field-replaceable modules and through-hole-friendly assemblies simplify depot-level repair. Note: true mil-spec screened variants are typically designated EP20K60E-MIL; this commercial grade is used in non-flight-critical subsystems only.
Recommandé
Test and Measurement Instrumentation
The EP20K60EQC208-3 forms the digital engine inside legacy oscilloscopes, logic analyzers, and protocol testers, generating stimulus patterns, capturing waveforms, and pre-processing data before upload to host software. The 1.72 ns propagation delay supports 200 MHz pattern generation in benchmark ATE, while 32 Kbit embedded SRAM serves as a deep capture buffer. With 148 I/Os, the FPGA drives large LCD character/graphical displays and parallel ADC front-ends. Engineering value: the deterministic MultiCore™ fabric ensures repeatable timing for compliance and characterization tests.

Notes de conception
The EP20K60EQC208-3 requires a stable 1.8 V core supply with ±5% tolerance; high-current transients during configuration must be decoupled with 0.1 µF X7R ceramic capacitors placed within 5 mm of every VCCINT/GND pin pair. According to Altera APEX-20KE design guidelines, bulk decoupling of 33 µF to 100 µF tantalum plus 10 µF ceramic is recommended near the device. For I/O banks using 3.3 V PCI, the VCCIO pin bank must be tied to 3.3 V independently from the 1.8 V core. Power sequencing should hold core voltage stable before JTAG/configuration begins; otherwise, configuration may fail with CRC errors.
The 208-pin PQFP package has 0.5 mm lead pitch and gull-wing leads designed for surface mount; maintain a minimum pad length of 1.0 mm beyond the package outline to allow reliable solder fillet formation. PCB land pattern should include thermal relief spokes on inner-layer power planes to prevent cold joints during reflow. Per Altera application notes, signal traces from the device should be length-matched within ±150 mil for 100 MHz operation to avoid skew-induced timing failures. Do NOT route high-speed clock signals under the PQFP body - the lead inductance can cause reflections and ringing.
Common pitfalls when designing with EP20K60EQC208-3: (1) Using Quartus II versions newer than v9.1, which dropped APEX-20KE support - design entry is limited to MAX+PLUS II or Quartus II v9.1sp2 and earlier; (2) Confusing the EQC208 (PQFP) package with the EFC324 (BGA-324) package - pinout and PCB footprint are NOT compatible; (3) Forgetting to assert nCONFIG high after VCCINT is stable - causes the device to remain in reset; (4) Using the -1 speed grade by accident when the design requires -3 timing margins; (5) Assuming 5 V tolerance on PCI I/O - the APEX 20KE PCI I/O is 3.3 V only. Always validate configuration bitstream compatibility with Quartus / MAX+PLUS II before PCB commit.
Estimated: at 160 MHz internal frequency and typical 60% toggle rate, the EP20K60EQC208-3 dissipates approximately 1.0-1.5 W of core power. The 208-pin PQFP package has a thermal resistance theta_JA of approximately 30-35 °C/W with standard JEDEC PCB footprint, giving a junction temperature rise of 30-50 °C above ambient at 25 °C. The device is rated 0-85 °C operating, so adequate cooling margin exists for most commercial designs. Industrial-temperature variants do not exist in the APEX 20KE family - for harsh environments, heatsinking the PQFP body or derating Fmax is recommended. Verify with the manufacturer datasheet for precise thermal figures.
