EPF10K100EQI240-2 概要
A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be electrically configured after manufacture to implement arbitrary digital logic. Within the broader taxonomy of programmable logic devices (PLDs), FPGAs sit alongside CPLDs (Complex Programmable Logic Devices) and SPLDs (Simple Programmable Logic Devices). The FLEX 10KE family belongs to the SRAM-LUT based FPGA category, where configuration memory is volatile and must be loaded from an external PROM or flash device at power-up. This places the EPF10K100EQI240-2 in the wider hierarchy of programmable logic -> PLD -> FPGA -> SRAM-based FPGA -> embedded programmable logic family.
Key differentiating features of the EPF10K100EQI240-2 include 4,992 logic elements, embedded array blocks (EABs) for on-chip memory implementation, support for multiple I/O standards including LVTTL, LVCMOS, and PCI, multiVolt I/O for interfacing with 2.5 V/3.3 V/5 V systems, and a 0.5 ns pin-to-pin propagation delay. The device integrates multiple 32-bit bus interfaces, JTAG IEEE 1149.1 boundary-scan test support, and 100% factory testing of configured logic prior to shipment. The PQFP-240 (S-PQFP-G240) package with 0.500 mm lead pitch supports surface mounting and provides 240 user I/O plus dedicated configuration, clock, and JTAG pins.
Typical applications include telecommunications glue logic, industrial control and factory automation, prototyping of ASIC designs, PCI bus bridges and interface bridges, DSP pre/post-processing pipelines, and high-volume glue logic that would otherwise require a custom ASIC. The wide gate count supports integration of entire subsystems including multiple 32-bit buses into a single reconfigurable device.
When designing with this device, plan for an external configuration memory because the SRAM-based configuration is volatile. Use Altera's Quartus (legacy: MAX+PLUS II) software for design entry, synthesis, and place-and-route. Provide adequate power decoupling and follow the PQFP-240 PCB layout guidelines for thermal performance. Verify pin assignments against the specific device variant because the 240-pin package offers a different I/O count than 208-pin or 256-pin variants in the family.

主な用途
EPF10K100EQI240-2 の用途: 6 件s: Telecommunications Glue Logic, Industrial Control and Factory Automation, ASIC Prototyping and Emulation, PCI Bus Bridge and Interface Logic, DSP Pre- and Post-Processing Pipelines, Legacy Replacement and Long-Life Equipment.
Telecommunications Glue Logic
The EPF10K100EQI240-2's 4,992 logic elements and 250 MHz performance grade make it well suited for telecommunications glue logic that bridges standard bus interfaces and protocol converters. Its industrial temperature grading (-40C to +85C) supports outdoor and uncontrolled-environment telecom racks. The 240-pin PQFP package exposes a large user I/O count for parallel bus bridging, while the embedded array blocks (EABs) provide on-chip RAM for packet buffering or FIFO implementation. Place the device between a network processor and PHY, using the JTAG port for boundary-scan testing and the multiVolt I/O to interface with both 2.5 V and 3.3 V rails typical of legacy telecom hardware.
おすすめ
Industrial Control and Factory Automation
The EPF10K100EQI240-2 is widely used in factory automation controllers where its 100,000-gate capacity can absorb entire subsystem designs that previously required multiple CPLDs or a small ASIC. Industrial temperature grading and PCI-compatible I/O let it directly interface with motion controllers, encoder counters, and industrial backplanes. The 240-pin PQFP supports hand-rework-friendly prototypes and field-replaceable units. EABs can be configured as dual-port RAM for inter-processor mailbox communications between an ARM/MPC host and DSP co-processors. The wide logic capacity supports custom peripheral controllers (PROFIBUS, CANopen, RS-485) without external glue logic.
おすすめ
ASIC Prototyping and Emulation
With 100,000 gates and 250 MHz internal performance, the EPF10K100EQI240-2 was a popular ASIC prototyping vehicle in the late 1990s and early 2000s, allowing design teams to validate RTL against real silicon before committing to NRE charges. Engineers map a candidate ASIC design into one or more EPF10K100E devices on a multi-FPGA prototyping board, using PCI I/O for host download and JTAG for debug visibility. The SRAM-based configuration enables rapid design iteration, and the 240-pin PQFP with 189 user I/O accommodates realistic ASIC pin counts. Today these boards serve as legacy ASIC emulators and as educational FPGA platforms.
おすすめ
PCI Bus Bridge and Interface Logic
The EPF10K100EQI240-2 includes PCI-compliant I/O drivers that meet the PCI Local Bus Specification 2.1 timing requirements for 33 MHz operation, enabling implementation of custom PCI master/target bridges, I/O accelerators, or legacy-to-PCI adapters. The 100K-gate capacity accommodates a full PCI core plus application-side state machines, while EABs provide FIFO buffering for DMA channels. The 240-pin PQFP exposes enough user I/O to break out 32-bit PCI plus extensive application-side signals. Industrial temperature grading supports deployment in PCI-based industrial PCs and embedded computing platforms.
おすすめ
DSP Pre- and Post-Processing Pipelines
The EPF10K100EQI240-2 complements external DSP processors by implementing pre-processing (FIR filtering, decimation, sample-rate conversion) and post-processing (interpolation, peak detection, FFT windowing) functions in parallel hardware. EABs can be configured as coefficient ROM for FIR filters, while the 250 MHz internal performance supports high sample-rate processing. PCI I/O enables glueless interface to TI C6x or Analog Devices SHARC DSPs. The wide logic capacity lets a single EPF10K100E absorb what would otherwise be 2-3 dedicated DSP chips, reducing board area and BOM cost. Industrial temperature grading suits outdoor DSP installations.
おすすめ
Legacy Replacement and Long-Life Equipment
The EPF10K100EQI240-2 is in active use as a maintenance replacement in long-life industrial, medical, and aerospace equipment originally designed around the FLEX 10KE family. Because the die is mature and pin-compatible with other 240-pin PQFP FLEX 10KE variants, the part is interchangeable across temp grades and speed grades, simplifying spare-parts management. Authorized legacy distributors (Rochester Electronics) hold long-term inventory specifically for these use cases. Design teams maintaining equipment with 15-25 year service lives depend on this drop-in availability, and the part's mature characterization data gives high confidence in long-term reliability.

設計ノート
The EPF10K100EQI240-2 requires both a 2.5 V VCCINT core supply and a separate VCCIO bank supply (typically 3.3 V or 2.5 V depending on I/O standard). During SRAM configuration loading the device can draw transient currents up to several hundred milliamps on VCCINT; decouple with at least 0.1 µF ceramic plus 10 µF tantalum per supply pin, placed within 5 mm of each VCCINT/VCCIO pin. Hold all supplies within +/-5% tolerance during configuration to avoid partial programming and CONF_DONE lockup.
Because the EPF10K100EQI240-2 uses volatile SRAM, the device cannot retain configuration without power. A configuration PROM (EPC2LC20, EPC8QC100, or compatible) is mandatory. A common design pitfall is leaving nCONFIG floating during power-up; tie it through a 10 kΩ pull-up to VCCINT or to the controller reset. Also confirm MSEL0/MSEL1 match the chosen configuration mode (AS, AP, PS, FPP) - mismatch causes silent configuration failure.
Estimated: at 250 MHz with 100% toggle rate and typical 2.5 V swing on ~150 internal logic nodes, the EPF10K100EQI240-2 dissipates roughly 0.7-1.2 W. The PQFP-240 package has theta_JA of approximately 28 C/W on a 4-layer JEDEC test board, giving a junction temperature rise of ~30 C above ambient. Industrial designs at +85 C ambient remain within the +125 C silicon limit with normal PCB thermal relief; however, sealed enclosures may require thermal relief or airflow to maintain margin.
Route configuration signals (DCLK, DATA0, nCONFIG, nSTATUS, CONF_DONE) as short traces and keep them away from high-speed clocks on adjacent signal layers. Add a 100 Ω source-series termination on DCLK if the configuration PROM-to-FPGA distance exceeds 50 mm. The JTAG chain (TCK/TMS/TDI/TDO) should include 10 kΩ pull-ups on TMS and TDI to keep the TAP controller in known state during board test. Provide a JTAG header for in-system programming.
コンプライアンス情報
Original EPF10K100EQI240-2 with SnPb finish is not RoHS compliant. For RoHS-bound designs use the Pb-free suffix variants (e.g., EPF10K100EQC240-2N or EPF10K100EQC240-2X). REACH compliance is maintained by Altera/Intel PSG documentation. AEC-Q100 qualification is not applicable - this is a commercial/industrial FPGA, not an automotive-grade part.
