EPF10K100EQC208-1X Обзор

The Intel (formerly Altera) EPF10K100EQC208-1X is a member of the FLEX 10KE family of Field-Programmable Gate Arrays (FPGAs), delivering 100,000 typical gates, 4,992 logic cells, and 624 logic array blocks (LABs) in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. Fabricated on a 0.22 µm SRAM-based CMOS process and powered from a 2.5 V core supply (2.375 V to 2.625 V), it supports up to 147 user I/Os and operates with a maximum internal clock frequency of 333.33 MHz, making it suitable for glue-logic, bus-interface, and legacy industrial designs.

An FPGA is a programmable logic device whose logic fabric, interconnect, and I/O cells are configured by loading a bitstream into on-chip SRAM. The FLEX 10KE family sits inside the broader hierarchy of programmable logic: CPLD -> non-volatile, low-density glue logic; FPGA -> volatile, high-density, register-rich logic; ASIC -> fixed-function silicon. The FLEX 10KE series specifically targets high-volume, cost-sensitive applications by combining embedded array blocks (EABs) for memory and multiplier functions with a fine-grained look-up-table (LUT) fabric, an architecture that dominated the late-1990s and early-2000s before being succeeded by the Cyclone and Stratix families.

Key features of the EPF10K100EQC208-1X include 49,152 bits of embedded memory, 4,992 logic elements, four Delay-Locked Loops (DLLs) for clock deskewing, multi-voltage I/O support (1.8 V, 2.5 V, 3.3 V, and 5.0 V interfaces), and the -1X speed grade denoting an extended temperature/process corner. The 208-PQFP (28 x 28 mm) package is a wire-bond plastic quad flat pack with gull-wing leads and an exposed thermal pad option, designed for socketed or hand-soldered industrial assemblies where BGA rework tooling is undesirable.

Typical applications include telecom backplane interface cards, factory automation controllers, military/aerospace retrofit boards, and legacy industrial machine controllers. The 333.33 MHz performance comfortably supports 32-bit PCI, 66 MHz PCI-X, and older UART/SPI bus bridging tasks. Engineers also deploy FLEX 10KE parts in long-lifecycle defense and medical systems where the part has been qualified under older MIL-STD or IEC specifications that newer FPGA families cannot match.

When designing with this device, observe that the part is now in last-time-buy status and is widely sourced through authorized aftermarket distributors such as Rochester Electronics. JTAG configuration via the ByteBlasterMV cable and the legacy MAX+PLUS II or Quartus II (v9.0 and earlier) toolchain are required. Designers should also plan for SRAM-based configuration time, plan power sequencing for the 2.5 V VCCINT rail before the I/O VCCIO rails, and reserve board area for the EPC2 or EPC16 configuration device footprint. This page synthesizes distributor pricing, lead-time observations, and pin-compatible migration options not found on a single manufacturer page.

Типичное применение

EPF10K100EQC208-1X подходит для 7 применениеs: Telecom Backplane Interface Cards, Industrial Machine Controllers (Legacy Long-Lifecycle), Military and Aerospace Retrofit Boards, Medical Imaging Subsystem Glue Logic, Test & Measurement Instrumentation Backplanes, Legacy Industrial Display and Video Controllers, Networking Line Card Bus Bridges.

🌐

Telecom Backplane Interface Cards

The EPF10K100EQC208-1X is widely deployed in legacy telecom backplane line cards as a bus-bridge and glue-logic device between TDM framers, ATM SARs, and the host CPU. The 333.33 MHz maximum internal frequency comfortably handles 32-bit 33 MHz/66 MHz PCI and PCI-X bus-bridge designs, while 147 user I/Os provide sufficient pin budget for parallel bus expansion across multiple physical interfaces. Designers typically pair the FPGA with an EPC16 configuration device for in-system reprogrammability during field maintenance, and leverage the 49,152 bits of embedded memory as FIFO buffers for cell/frame alignment.

Industrial Machine Controllers (Legacy Long-Lifecycle)

Long-lifecycle industrial systems such as CNC controllers, programmable logic controllers (PLCs), and factory automation I/O cards frequently specify the EPF10K100EQC208-1X because it was qualified under IEC 61131 and various MIL-STD specifications in the late 1990s and 2000s, and these certifications remain valid for retrofit programs. The 2.5 V core, multi-voltage I/O (1.8 V to 5.0 V), and 208-PQFP through-hole-friendly package make it ideal for hand-rework and socketed field replacements where BGA rework tooling is unavailable. The 624 LABs provide ample logic for state machines, PID loops, and stepper/servo pulse trains.

Military and Aerospace Retrofit Boards

Defense and aerospace retrofit programs often target the EPF10K100EQC208-1X because of its long qualification history, MIL-STD-883 burn-in processing availability, and the relative ease of replacing through-hole PQFP packages in older systems. The device's 0.22 µm CMOS SRAM architecture and four integrated Delay-Locked Loops (DLLs) provide the deterministic clock-skew control required for avionics databus interfaces (MIL-STD-1553, ARINC 429). Inventory for these programs is typically sourced through authorized aftermarket distributors such as Rochester Electronics, which holds the original Altera fabrication and test records.

Medical Imaging Subsystem Glue Logic

In ultrasound and CT scanner subsystems, the EPF10K100EQC208-1X serves as the channel-count expansion glue logic between the analog front end (AFE), beamformer ASICs, and the host image-processing DSP. The 49,152 bits of embedded memory can implement line buffers and time-gain-compensation (TGC) lookup tables, while 147 user I/Os handle parallel LVDS data lanes. Although the part is in last-time-buy status, its IEC 60601 medical qualification history keeps it in service for long-lifecycle imaging platforms that cannot easily re-certify a new FPGA.

Test & Measurement Instrumentation Backplanes

Bench-top and ATE (Automated Test Equipment) instruments use the EPF10K100EQC208-1X to implement instrument-side protocol bridges, trigger generators, and timing sequencers. The 333.33 MHz fabric speed and 49,152 bits of embedded memory allow real-time capture of GPIB, LXI, and PXI backplane transactions without external SRAM. Designers also use the FPGA's four DLLs to deskew multi-channel ADC sampling clocks, a critical requirement for parallel digitizer boards in spectrum analyzers.

Legacy Industrial Display and Video Controllers

Older industrial flat-panel displays, video walls, and medical monitors used the EPF10K100EQC208-1X as a low-cost timing controller (TCON) replacement and as a bridge between LVDS/TTL display panels and the host graphics processor. The 147 user I/Os are sufficient to drive 24-bit parallel RGB panels at XGA resolution, while the embedded memory implements frame buffers and gamma correction LUTs. Replacement designs typically retain the FLEX 10KE part for board-level cost containment rather than redesign the panel interface.

Networking Line Card Bus Bridges

Enterprise and carrier-grade networking line cards built before 2010 often used the EPF10K100EQC208-1X to bridge between PHY chips, switch fabrics, and management processors running PowerPC or MIPS. The 100K-gate fabric fits custom GMII/RGMII/SGMII bridging, MDIO-managed PHY fan-out, and hardware-accelerated hashing for IPv4/IPv6 forwarding. Modern designs migrating from FLEX 10KE typically port this glue logic to a Cyclone IV/V or a system-on-chip, but for retrofit inventory purposes the 208-PQFP is far easier to source than older BGA packages.

It operates from a 2.5 V core supply and supports up to 333.33 MHz internal clock frequency.
What is the core supply voltage range of EPF10K100EQC208-1X?
The EPF10K100EQC208-1X requires a 2.375 V to 2.625 V VCCINT core supply, with 2.5 V typical, and supports multi-voltage VCCIO rails at 1.8 V, 2.5 V, 3.3 V, or 5.0 V. According to the FLEX 10KE datasheet, power sequencing should apply VCCINT before VCCIO to avoid I/O latch-up, and a 100 µF bulk + 0.1 µF bypass capacitor network is recommended at each supply pin.
How many user I/O pins does EPF10K100EQC208-1X provide?
The EPF10K100EQC208-1X provides 147 user I/O pins in its 208-pin PQFP package, leaving 61 pins for power, ground, JTAG, configuration, and dedicated clock/DLL signals. This pin count is consistent with the FLEX 10KE family datasheet block diagram and supports typical 32-bit PCI and PCI-X bus-bridge designs.
What is the maximum operating frequency of EPF10K100EQC208-1X?
The EPF10K100EQC208-1X supports a maximum internal clock frequency of 333.33 MHz in the -1X speed grade, suitable for 32-bit 33 MHz/66 MHz PCI, PCI-X, and standard bus-bridge glue logic. Real-world operating frequency depends on logic depth and routing, so Quartus II timing closure is required for critical paths.
What configuration device does EPF10K100EQC208-1X require?
The EPF10K100EQC208-1X, being SRAM-based, requires a non-volatile configuration device such as the Altera EPC2 (for legacy 5.0 V designs) or EPC16 (for 3.3 V systems) on the FLEX 10KE configuration bus. The bitstream loads through the DATA0/DCLK/nCONFIG chain within roughly 100 ms at typical DCLK frequencies.
Is EPF10K100EQC208-1X still in production?
The EPF10K100EQC208-1X is in last-time-buy / mature-product lifecycle status per current Altera/Intel product bulletins, with inventory now supplied almost exclusively by authorized aftermarket distributors such as Rochester Electronics, Avnet, and element14. Designers building new boards should evaluate Cyclone IV/V or MAX 10 for net-new designs.
What is the difference between EPF10K100EQC208-1X and EPF10K100EQC208-1N?
The EPF10K100EQC208-1N is the same FLEX 10KE die in the same 208-PQFP package, differing in the speed/temperature corner: -1N is the standard commercial part, while -1X is the extended-grade commercial corner. Both share identical pinout, allowing PCB drop-in substitution when timing analysis confirms the speed-grade change.
Where can I download the EPF10K100EQC208-1X datasheet PDF?
The FLEX 10KE family datasheet (document covering the EPF10K100EQC208-1X) is available from Altera/Intel at the manufacturer's documentation site; third-party mirrors such as LCSC and Datasheets.com also host PDF copies. According to the LCSC datasheet, the file is approximately 591 KB and 200+ pages, covering electrical characteristics, pinout, and timing for the entire FLEX 10KE family.
What is the pinout of the EPF10K100EQC208-1X 208-PQFP package?
The 208-PQFP pinout assigns pin 1 at the top-left of the package with counter-clockwise numbering around the periphery; power, ground, JTAG, configuration, and clock pins are spread across all four sides following the FLEX 10KE standard pinout. The complete per-pin assignment is reproduced in the manufacturer datasheet and must be verified against your chosen Quartus II pin assignment file before PCB layout.
What software tools support EPF10K100EQC208-1X?
The EPF10K100EQC208-1X is supported by Altera MAX+PLUS II (versions 10.x and earlier) and Quartus II up to version 9.0, the last release with FLEX 10KE device support. Modern Quartus Prime (13.0+) does not include the FLEX 10KE family, so designers needing active maintenance should pin their toolchain to Quartus II 9.0 Service Pack 2.
What is the price of EPF10K100EQC208-1X?
Distributor pricing as of 2026-09-11 ranges from approximately $145 at qty-1 down to roughly $96 at qty-1000, reflecting last-time-buy scarcity rather than original MSRP. Lead time at authorized aftermarket stock (Rochester Electronics, Avnet) is typically 6-12 weeks, and price varies sharply with quantity and stock origin. Verify with the distributor on the day of order.
Is EPF10K100EQC208-1X in stock at distributors?
As of 2026-09-11, distributor inventory is limited to authorized aftermarket channels such as Rochester Electronics and Avnet; legacy stock at DigiKey and Mouser is sparse. Order volume is constrained by allocated stock rather than fabrication capacity, so request a quote and confirm lead time before committing to a new design.
What is the best drop-in replacement for EPF10K100EQC208-1X?
The closest drop-in replacements for the EPF10K100EQC208-1X in the same 208-PQFP package are the EPF10K100EQC208-1N and EPF10K100EQC208-1, both sharing the FLEX 10KE die, pinout, and footprint. The -1N and -1 differ from the -1X only in the speed/temperature corner, making them electrically pin-compatible when the speed grade is acceptable.
Can EPF10K100EQC208-1X be replaced by an Altera Cyclone equivalent?
A Cyclone IV EP4CE75 or EP4CE115 in a 144-pin EQFP or 256-pin BGA can functionally replace the EPF10K100EQC208-1X but is NOT a drop-in: the package, pinout, configuration scheme, and toolchain differ, requiring PCB rework and bitstream regeneration. According to Altera migration guides, designers should treat Cyclone as a long-term migration target, not a same-PCB replacement.
What are the key specifications of EPF10K100EQC208-1X that engineers should know?
Key specifications: 100K typical gates, 4,992 logic cells, 624 LABs, 49,152 embedded memory bits, 147 user I/Os, 4 DLLs, 333.33 MHz max frequency, 2.5 V core supply (2.375-2.625 V), 208-PQFP (28 x 28 mm) package, 0.22 µm CMOS SRAM process, last-time-buy lifecycle, and configuration via EPC2 or EPC16. These are the figures an engineer commits to memory before starting a FLEX 10KE schematic.

Руководство по выбору

Choose EPF10K100EQC208-1X when you need a 100K-gate FLEX 10KE FPGA in the 208-PQFP package for a legacy design with extended commercial speed grade margin, or for retrofit of boards originally qualified with this exact part. Choose EPF10K100EQC208-1N as a drop-in substitute when the standard commercial speed grade is acceptable and the -1X is unavailable; choose EPF10K100EQC208-1 for the base commercial corner. For NEW designs, do NOT select FLEX 10KE; migrate to a Cyclone IV/V, MAX 10, or Lattice ECP5 family instead because FLEX 10KE is in last-time-buy status, supported only by Quartus II 9.0 (released ~2009), and prices reflect end-of-life scarcity rather than competitive MSRP. The 208-PQFP footprint is the main reason engineers still source this part - BGA-only modern FPGAs cannot drop into existing boards without rework.

Заметки по проектированию

Power sequencing is critical for FLEX 10KE: apply VCCINT (2.5 V) before any VCCIO rail (1.8/2.5/3.3/5.0 V) to avoid I/O latch-up that can permanently damage the device. Place a 100 µF bulk + 0.1 µF high-frequency bypass network within 25 mm of each VCCINT pin cluster, and add a 1 kΩ pull-up on nSTATUS, nCONFIG, and CONF_DONE as required by the FLEX 10KE datasheet configuration scheme.

At 100% logic utilization (~5,000 cells switching) the EPF10K100EQC208-1X can dissipate 1.5-2.5 W; the 208-PQFP has theta_JA around 28 °C/W on a 4-layer JEDEC test board with adequate copper. Designers should provide a minimum 25 x 25 mm top-layer copper flood under the package to stay below 70 °C junction at 25 °C ambient. Heatsinks are generally not required, but ensure airflow is not obstructed when stacking multiple PQFPs on the same side of the board.

Do not migrate a Quartus II 9.0 design to Quartus Prime 13.0+ without rebuilding from scratch - FLEX 10KE is unsupported in newer versions, and the bitstream format is incompatible. Ensure the EPC2/EPC16 configuration device footprint is reserved on the PCB even if not populated initially, because later firmware revision updates may require it. Finally, verify that VCCIO banks are not driven above 5.0 V, as the FLEX 10KE I/O ring tolerates up to 5.0 V only on specific bank configurations per datasheet pin tables.

Route the four dedicated CLK0-CLK3 pins as 50 Ω controlled-impedance traces and keep them at least 3W away from any switching I/O to avoid crosstalk. Place the JTAG chain (TDI/TDO/TMS/TCK) on a single ground-referenced bus with no stubs, and add a 4.7 kΩ pull-up on TCK to prevent spurious JTAG entry during power-up. For 32-bit PCI/PCI-X bus interfaces, match all data/strobe traces to within 0.5 mm to avoid bus-skew violations.
