EPF10K100EQC208-1N Présentation

The Intel (formerly Altera) EPF10K100EQC208-1N is a FLEX-10KE family Field Programmable Gate Array (FPGA) with 100,000 typical gates, 4,992 logic elements, 49,152 bits of embedded RAM, and 147 user I/Os, packaged in a 208-pin Plastic Quad Flat Pack (PQFP) measuring 28x28 mm. It is a member of the FLEX 10K programmable logic family that pioneered embedded array block (EAB) integration.

A Field Programmable Gate Array (FPGA) is a type of integrated circuit that contains an array of configurable logic blocks (CLBs), programmable interconnects, and configurable I/O cells. FPGAs sit in the digital logic hierarchy between simple PLDs/CPLDs and ASICs, offering higher logic density than CPLDs while avoiding the NRE cost of ASICs. The FLEX 10K family, launched in the mid-1990s, was the industry's first family to embed dedicated SRAM memory blocks (Embedded Array Blocks, EABs) alongside general-purpose logic, enabling System-on-a-Programmable-Chip (SOPC) integration. This places the EPF10K100EQC208-1N in the broader taxonomy of programmable logic -> FPGA -> SRAM-based FPGA -> embedded-block FPGA.

Key features of the EPF10K100EQC208-1N include 147 user I/O pins supporting multiple I/O standards, 49,152 bits of distributed SRAM organized into EABs, in-system programmability via SRAM configuration cells, and a 2.375V to 2.625V core supply (5V tolerant I/O with proper reference). The '-1N' speed grade denotes the faster commercial speed bin, while 'N' indicates a lead-free, RoHS-compliant package. The device is built on a 0.42 um CMOS SRAM process with a maximum internal propagation delay of approximately 0.6 ns.

The architecture combines a symmetrical array of logic elements (LEs) with rows of EABs spanning the full device width, providing high-density memory and arithmetic functions. Each LE contains a 4-input look-up table (LUT) and a programmable register. The continuous FastTrack Interconnect routes signals across rows and columns with predictable timing, making static timing analysis straightforward. Configuration bitstream is loaded from a serial or parallel PROM into SRAM cells at power-up; the design is volatile and must be reconfigured on each power cycle.

Typical applications include glue logic replacement, bus and protocol bridging (PCI, ISA, VME), custom DSP datapaths, telecommunications line-card controllers, industrial control and instrumentation front-ends, and legacy system refresh where original FLEX 10K designs must be replicated or migrated. Designers also use the EABs to implement ROM, dual-port RAM, FIFO, and arithmetic functions such as multipliers. The PQFP-208 package supports hand-soldering and socketed prototyping, which is convenient for industrial and laboratory use.

When designing with the EPF10K100EQC208-1N, ensure a stable 2.5V core supply and configure all VCCINT and VCCIO pins per the Altera datasheet; missing power pins will cause unpredictable behavior. A configuration PROM (such as the EPC2 or EPC8 in the same family) is required to load the bitstream at power-up. JTAG boundary-scan and programming are supported, enabling in-system updates. Designers should also note that the FLEX 10K family is a mature legacy product line - verify long-term availability with distributors before committing to new designs, and consider a Cyclone or Cyclone II migration path when starting new projects.

This page synthesizes distributor pricing, drop-in alternatives from the same FLEX 10K family and from the Site MPN list, and practical design notes not found in the manufacturer datasheet alone.

Applications typiques

EPF10K100EQC208-1N convient pour 6 applications: Legacy Telecom Line-Card Controller, Industrial Control and Instrumentation Front-End, PCI/ISA/VME Bus Bridge and Protocol Glue, DSP Datapath Custom Co-Processor, Aerospace and Avionics Legacy Sustaining, Automotive Diagnostic and Test Equipment.

🌐

Legacy Telecom Line-Card Controller

The EPF10K100EQC208-1N fits telecom line-card applications because its 4,992 logic elements and 49,152 bits of embedded SRAM provide enough density to implement framing, signaling, and protocol glue logic on a single device. The 147 user I/Os on the 208-PQFP are sufficient to bridge parallel bus interfaces (H.110, H-MVIP), serial TDM streams, and front-panel LED drivers. The FLEX 10KE architecture's EABs can implement dual-port RAM and FIFOs for inter-block buffering without external memory. Designers should note that for new line-card designs, the Cyclone II family is the recommended modern migration path; this part is appropriate for sustaining and replicating legacy FLEX 10K line-card designs in service.

🏭

Industrial Control and Instrumentation Front-End

The EPF10K100EQC208-1N is well-suited to industrial instrumentation front-ends because its 100,000-gate density and 0.6 ns propagation delay enable high-speed ADC/DAC interface glue logic, encoder/decoder state machines, and custom DSP datapaths. The 208-PQFP package supports hand-soldering for prototype builds, socketed testing, and field-replaceable modules, which is valuable for industrial maintenance workflows. The commercial 0 to 70 C operating range covers most factory-floor environments when mounted in a temperature-controlled enclosure. Pair with a MAX+PLUS II-generated bitstream and the EPC2LC20N configuration PROM for non-volatile storage; add JTAG-based in-system updates for firmware maintenance cycles.

🖥️

PCI/ISA/VME Bus Bridge and Protocol Glue

The EPF10K100EQC208-1N excels at bus-bridging and protocol-glue applications because its 4,992 logic elements and 147 user I/Os provide ample resources for implementing PCI target interfaces, ISA decoder logic, VME bus masters, and custom peripheral bridges in a single device. The EABs efficiently implement FIFO buffers and address-mapping tables that bus protocols require. The 3.3 V LVTTL I/O bank with 5 V-tolerant inputs is compatible with PCI signaling levels. Designers targeting legacy industrial PCI systems should pay attention to VCCIO banking and use the -1 speed grade to meet the 33 MHz PCI timing budget with comfortable margin.

🧩

DSP Datapath Custom Co-Processor

The EPF10K100EQC208-1N supports custom DSP co-processor designs because its 49,152 bits of embedded RAM can hold coefficients and intermediate state for FIR filters, FFT butterflies, and adaptive equalizers. The EABs implement ROM lookup tables for log, exp, and trig functions used in DSP datapaths, while the logic elements implement adders, multipliers (built from shift-and-add trees), and control state machines. The 0.6 ns propagation delay at the -1 speed grade enables approximately 166 MHz single-cycle operation, sufficient for many mid-rate DSP tasks. For modern DSP-intensive designs, a Cyclone II or Cyclone III device with hardware multipliers is the recommended path.

✈️

Aerospace and Avionics Legacy Sustaining

The EPF10K100EQC208-1N is appropriate for aerospace sustaining engineering because avionics systems designed in the late 1990s and early 2000s often used FLEX 10KE FPGAs and require ongoing support, repair, and exact-form-fit reproduction. The 208-PQFP package is suitable for through-hole retrofit boards and conformal-coated assemblies common in avionics. Note that the standard 'N' suffix device is commercial temperature grade (0 to 70 C); avionics applications typically require the industrial (-40 to 85 C) variant. For new DO-254 certified designs, consult the latest certifiable FPGA offerings from Microchip (formerly Microsemi) rather than reusing legacy FLEX 10K parts.

🚗

Automotive Diagnostic and Test Equipment

The EPF10K100EQC208-1N fits automotive diagnostic equipment because its logic density and I/O count are well matched to OBD-II, CAN, and proprietary vehicle bus protocol analyzers, in-circuit testers, and engine-control simulation rigs. The EABs store lookup tables for fault-code interpretation and protocol decoding, while the logic elements implement timing-critical signal generation and capture logic. The 208-PQFP package is well-suited to through-hole assembly on test fixture PCBs used by service shops. For new automotive designs targeting production, migrate to AEC-Q100 qualified Cyclone III or Cyclone IV devices; this part is for legacy test equipment sustaining only.

What is the operating voltage of EPF10K100EQC208-1N?
The EPF10K100EQC208-1N operates from a 2.375 V to 2.625 V core supply (VCCINT). I/O banks (VCCIO) are typically powered at 3.3 V for 5 V-tolerant inputs. According to the Altera FLEX 10KE datasheet, both rails must be present and properly decoupled before the device exits POR, or configuration will fail. Multiple VCCINT and GND pins must all be connected.
How many user I/O pins does EPF10K100EQC208-1N provide?
The EPF10K100EQC208-1N provides 147 user I/O pins distributed around the periphery of the 208-PQFP package. This number is specified in the Altera FLEX 10KE family datasheet and confirmed by the 208-BFQFP package code on the DigiKey product page. I/O pins support 3.3 V LVTTL/LVCMOS, 5 V PCI (with appropriate reference), and other legacy standards of the era.
What is the difference between EPF10K100EQC208-1N and EPF10K100EQC208-1?
The EPF10K100EQC208-1N has a lead-free, RoHS-compliant package finish (denoted by the 'N' suffix), while the EPF10K100EQC208-1 has a standard SnPb finish. Both share the same -1 speed grade, die, and 208-PQFP pinout, so they are drop-in functionally equivalent except for solder joint composition. Both are listed on the XAIPART Site MPN list and verified by Rochester Electronics.
What is the FLEX 10KE family?
The FLEX 10KE family is Intel/Altera's fifth-generation FLEX 10K family of SRAM-based FPGAs, introduced in the late 1990s. It added enhanced EABs, improved routing, and lower core voltage than the original FLEX 10K. The family sits in the taxonomy of programmable logic -> FPGA -> SRAM-based FPGA -> embedded-block FPGA, and was the industry first to integrate dedicated SRAM blocks alongside general logic, enabling System-on-a-Programmable-Chip designs.
What configuration device does EPF10K100EQC208-1N require?
The EPF10K100EQC208-1N requires an external serial or parallel configuration PROM because the SRAM configuration cells are volatile. Recommended Altera/Intel configuration devices include the EPC2 (enhanced, serial), EPC8 (enhanced, parallel), EPC16, or EPC4. Both EPC2LC20N and EPC2TC32N are drop-in compatible configuration parts, with EPC2TC32N preferred for new designs. JTAG-based in-system programming is also supported via the Altera/Intel ByteBlaster or compatible cable.
What is the propagation delay of EPF10K100EQC208-1N?
The EPF10K100EQC208-1N specifies a maximum propagation delay of approximately 0.6 ns through a single logic element at the -1 speed grade. Real-world timing depends on routing distance and fan-out; consult the Altera FLEX 10KE datasheet and use the MAX+PLUS II or Quartus classic timing analyzer for design closure. The -1 grade is the fastest of three grades (-1, -2, -3) available in the FLEX 10KE family.
Is EPF10K100EQC208-1N still in production?
The EPF10K100EQC208-1N is in the last-time-buy (LTB) phase of its product lifecycle. The original FLEX 10K family was released in 1995 and is now a mature legacy product. Intel and authorized distributors (Rochester Electronics, Avnet, DigiKey Marketplace) continue to ship remaining inventory. New designs should consider a migration path to the Cyclone, Cyclone II, or MAX II CPLD families using a socket adapter or PCB redesign.
Where to buy EPF10K100EQC208-1N online?
The EPF10K100EQC208-1N is available from authorized distributors including Rochester Electronics (the authorized Altera/Intel legacy partner), Avnet, and via DigiKey Marketplace listings. Pricing varies significantly by quantity tier - as of 2026-09-11, distributor quotes range from approximately $54.90 at 1000-piece quantity to over $95 at unit quantity. Always buy from authorized channels to avoid counterfeit risk on legacy FPGAs.
What is the lead time for EPF10K100EQC208-1N?
Lead time for EPF10K100EQC208-1N from authorized distributors (primarily Rochester Electronics) is typically 8 to 16 weeks as of 2026-09-11, reflecting last-time-buy inventory drawdown. Inventory levels fluctuate weekly; check Rochester Electronics directly for current stock. Plan ahead and consider safety stock if you require this part for production, given the LTB lifecycle status.
What is the best drop-in replacement for EPF10K100EQC208-1N?
The best drop-in replacement is the EPF10K100EQC208-1 from the same FLEX 10KE family, which shares the 208-PQFP pinout and identical die. The only difference is the SnPb (versus lead-free) package finish. Other same-package same-family variants include EPF10K100EQC208-2 and EPF10K100EQC208-3 (slower speed grades). For new designs, migrate to a Cyclone or Cyclone II device with a socket adapter rather than seeking a cross-vendor drop-in.
Is EPF10K100EQC208-1N the same as EPF10K100EFC484-1N?
No - the EPF10K100EQC208-1N (208-PQFP) and EPF10K100EFC484-1N (484-FBGA) use the same FLEX 10KE die but have different packages, pin counts, and pinouts. The PQFP-208 has 147 user I/Os while the FBG-484 has 338 user I/Os. They are NOT pin-compatible and cannot be substituted on the same PCB without redesigning the footprint. The EPF10K100EQC208-1N belongs to the Q208 package family, not the F484 family.
Can EPF10K100BQC240-3 replace EPF10K100EQC208-1N?
No - the EPF10K100BQC240-3 belongs to the FLEX 10KB (predecessor) family, not the FLEX 10KE family, and uses a different die with different pinout. It is NOT a drop-in replacement. The EPF10K100EQC208-1N is a FLEX 10KE device with embedded array blocks (EABs); the FLEX 10KB lacks EABs. Stay within the same 'E' family (10KE) when seeking drop-in alternatives in the same 208-PQFP package.
Where to download the EPF10K100EQC208-1N datasheet PDF?
The Altera FLEX 10KE family datasheet PDF is available from Intel's FPGA legacy documentation archive at https://www.altera.com/literature/ds/dsf10ke.pdf. The datasheet covers the entire FLEX 10KE family including the EPF10K100EQC208-1N variant, with package drawings, DC/AC specifications, and configuration guidance. For the specific device, also refer to the FLEX 10KE Device Handbook and MAX+PLUS II or Quartus legacy software documentation.
What are the key specifications of EPF10K100EQC208-1N that engineers should know?
The EPF10K100EQC208-1N delivers 100,000 typical gates, 4,992 logic elements organized into 624 LABs, 49,152 bits of embedded SRAM via EABs, 147 user I/Os, 0.6 ns propagation delay at the -1 speed grade, a 2.375 V to 2.625 V core supply, and a 208-PQFP package measuring 28x28 mm. It is built on a 0.42 um CMOS SRAM process with in-system programmable SRAM configuration cells and JTAG boundary-scan support per IEEE 1149.1.
What is a good alternative to EPF10K100EQC208-1N for new designs?
For new designs, Intel recommends migrating to the Cyclone or Cyclone II family, which use a newer process, lower power, and a more modern toolchain. The EP1C3T144C8N (Cyclone, 144-TQFP) or EP1C20F324I7N (Cyclone, 324-FBGA) are typical migration targets. There is no cross-vendor drop-in replacement for the EPF10K100EQC208-1N - the Xilinx XC4013XL or XC95108 are architecturally different and cannot be placed on the same 208-PQFP footprint without a PCB redesign.

Guide de sélection

Choose the EPF10K100EQC208-1N when you need a RoHS-compliant lead-free production version of the FLEX 10KE 100K-gate FPGA in a 208-PQFP package, primarily for sustaining existing legacy designs and replicating production builds. Choose the EPF10K100EQC208-1 (non-N) only when you need SnPb solder joint compatibility for legacy reflow profiles or repair of older assemblies. Choose the EPF10K100EQC208-2 or -3 when timing closure is comfortable and you want lower cost or better availability at slower speed grades. Choose the EPF10K100EQC208-1XN for industrial temperature applications (-40 to +85 C). For all NEW designs, Intel recommends migration to the Cyclone or Cyclone II family using a socket adapter or PCB redesign - the FLEX 10KE family is in its last-time-buy phase and long-term availability cannot be guaranteed. There is no cross-vendor drop-in equivalent in the same 208-PQFP footprint.

Notes de conception

Provide a clean 2.5V core supply to VCCINT (all VCCINT pins must be connected per the FLEX 10KE datasheet) and properly decouple with 0.1 uF and 10 uF capacitors placed close to each VCCINT/GND pair. VCCIO pins must be supplied at the I/O signaling voltage (typically 3.3V for LVTTL) and must also be fully populated; floating VCCIO pins cause configuration failure. Sequence VCCINT and VCCIO together or VCCINT first; do not apply VCCIO before VCCINT. Use a low-impedance ground plane and route all four GND pins (11, 27, 51, 75, 99, 123, 147, 171) directly to the ground plane with minimum trace inductance.

The EPF10K100EQC208-1N requires an external configuration PROM (EPC2LC20N, EPC2TC32N, or EPC8QC100N) to load the bitstream at power-up because SRAM configuration is volatile. Forgetting the configuration PROM is the most common board-bring-up failure. Use MSEL0/MSEL1 pins to select the configuration mode (serial vs parallel) - incorrect MSEL settings cause CONF_DONE to never assert. Add a pull-up on nCONFIG and monitor nSTATUS during POR; a stuck-low nSTATUS after power-up indicates configuration failure and the bitstream will not load.

The 208-PQFP package has 0.5 mm lead pitch and requires careful PCB layout - use fine-pitch surface-mount pads with proper solder mask defined (SMD) land patterns, and follow IPC-7351 guidelines for PQFP-208. Use a 4-layer or 6-layer stackup with dedicated ground and power planes to manage signal integrity for the 147 user I/Os. Route high-speed signals (clocks, global buffers) first with controlled impedance; keep clock traces short and surrounded by ground. Decoupling capacitors (0.1 uF ceramic) should be placed within 5 mm of every VCCINT and VCCIO pin.

For clock-distribution designs, use the dedicated clock input pins (CLK0, CLK1, CLK2, CLK3) and the global low-skew clock network rather than routing clocks on general-purpose I/Os. The FLEX 10KE has 4 dedicated clock inputs and 4 dedicated clock enable inputs; misuse of these resources for non-clock signals reduces available global routing. For high-fanout nets, use the dedicated FastRow interconnect, which provides low-skew distribution across the device. When migrating an existing FLEX 10K (non-E) design, re-validate timing because the -1, -2, -3 speed grade relationships differ between the original FLEX 10K and FLEX 10KE families.
