EPF10K30EQC208-1X 개요
A field programmable gate array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs), embedded memory arrays, and programmable interconnects. The FLEX 10KE family belongs to the hierarchy of programmable logic devices (PLDs) and was among the earliest commercial architectures to merge a look-up-table (LUT) based logic fabric with embedded array blocks (EABs) for on-chip RAM and ROM. Within Intel/Altera's taxonomy, FLEX 10KE sits between the classic FLEX 10K and the subsequent APEX family, targeting high-volume glue-logic, bus-interface, and DSP pre-processing applications of the late 1990s and early 2000s.
Key features of the EPF10K30EQC208-1X include 216 logic array blocks (LABs), an internal frequency capability quoted by distributors at up to 250 MHz (fabric-dependent), a 0.22 micrometer CMOS process, embedded array blocks for distributed RAM/ROM, and JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan interface. The "-1X" speed grade and "C" temperature grade designate a faster commercial-temperature variant.
Architecturally, the FLEX 10KE device combines 1,728 logic elements organized in LABs of 8 LEs each, four embedded array blocks (EABs) for memory functions, and FastTrack interconnect routing. The 208-PQFP package provides 147 usable I/O pins with multi-voltage I/O standards including 3.3 V PCI compliance, making the part suitable for mixed-voltage system designs.
Typical applications include telecommunications line cards, industrial control and factory automation controllers, PCI bridge and bus-interface logic, video processing front-ends, and legacy glue-logic replacement in mature embedded systems. The combination of SRAM-based configuration and on-chip RAM also makes it useful for prototyping ASICs and implementing custom state machines.
When designing with this part, note that it is fabricated on a 5 V-tolerant legacy process; modern system-on-chip designs typically pair FLEX 10KE with a separate 3.3 V/5 V interface transceiver. Designers should also budget for the configuration EEPROM (EPC2 or compatible) and observe the IOREF, VCCINT, and VCCIO decoupling requirements documented in the datasheet.
This page synthesizes distributor pricing from DigiKey, Mouser, Octopart and Rochester Electronics, same-brand FLEX 10KE drop-in alternatives, and practical design guidance not found in the manufacturer datasheet alone.

일반적인 애플리케이션
EPF10K30EQC208-1X 적합 용도: 7 애플리케이션s: Telecommunications Line Cards, Industrial Control and Factory Automation, PCI Bus Interface and Bridge Logic, Video Processing Front-Ends, ASIC Prototyping and Emulation, Legacy Glue Logic Replacement, Test and Measurement Instrumentation.
Telecommunications Line Cards
The EPF10K30EQC208-1X is well matched to telecom line card designs where 30K gates of LUT-based logic, 147 I/O pins, and on-chip RAM are needed for protocol glue, framer interfacing, and TDM bus aggregation. Its 2.5 V core and 3.3 V I/O directly interface legacy 3.3 V framers and SERDES framer companion chips of the late 1990s / early 2000s. The device's JTAG (IEEE 1149.1) interface simplifies in-system programming and board-level boundary-scan test on high-density backplanes. Compared to a CPLD alternative, the FLEX 10KE fabric provides roughly 4x the logic capacity at similar unit cost, while consuming modest quiescent current. Designers should pair the part with a 2.5 V LDO and bulk decoupling per the Altera reference design and budget for an EPC2/EPC8 configuration PROM.
추천
Industrial Control and Factory Automation
The EPF10K30EQC208-1X provides the I/O count and embedded memory needed for industrial PLC I/O expansion, motor-control state machines, and fieldbus protocol conversion (Profibus, DeviceNet legacy bridges). Its 147 user I/O pins map naturally to multi-axis encoder inputs, opto-isolated digital I/O banks, and stepper-motor pulse generators, while the 24,576 bits of distributed RAM hold commutation tables and PID coefficient sets. The commercial 0 C to 70 C temperature grade suits indoor control cabinet environments, and the 28x28 mm PQFP package is straightforward to rework on through-hole-friendly industrial PCBs. Compared to a microcontroller, the FLEX 10KE fabric allows parallel logic execution of multiple axis controllers without firmware scheduling jitter, and its SRAM configuration supports remote firmware upgrades via JTAG in the field.
추천
PCI Bus Interface and Bridge Logic
The EPF10K30EQC208-1X is qualified for 33 MHz, 32-bit PCI bus bridge applications because its I/O banks support 3.3 V PCI signaling with the required 5 V tolerance margin per the PCI Local Bus Specification. The 1,728 logic elements and 24 Kb of embedded RAM can implement a target or master bridge state machine plus FIFOs without external SRAM, and the 147 I/O pins comfortably accommodate 32-bit data + 32-bit address plus control. Designers can pair this FLEX 10KE part with a downstream microcontroller or DSP via the unused I/O, building a single-FPGA PCI mezzanine card (PMC) or CompactPCI bridge. Compared to discrete 74-series glue logic, the EPF10K30EQC208-1X consolidates roughly 20-30 logic ICs into one device, dramatically simplifying PCB layout and reducing board area.
추천
Video Processing Front-Ends
The EPF10K30EQC208-1X is suitable for legacy video capture, scan-rate conversion, and overlay-graphic controllers because its embedded RAM can buffer a full line of standard-definition video, and the 147 I/O pins accommodate 16-bit video buses plus sync, blanking, and clock signals. Designers in the late 1990s used this part for broadcast equipment and digital video recorders (DVR) where ASIC NRE was unjustified. The 0.6 ns propagation delay enables pixel-rate processing at 27 MHz video clocks with margin. The PQFP-208 package is preferred over BGA for prototype and low-volume video equipment because it allows hand-rework. Compared to a modern Cyclone IV, the EPF10K30EQC208-1X has roughly 1/4 the RAM and 1/3 the LE count, but is still adequate for SD-resolution pipelines.
추천
ASIC Prototyping and Emulation
Engineers use the EPF10K30EQC208-1X as a vehicle for prototyping custom ASICs because its LUT-based fabric, embedded RAM, and JTAG configuration enable rapid RTL iteration with Quartus design software. Multiple FLEX 10KE devices can be chained via JTAG to emulate larger ASICs for pre-silicon software development. The 24 Kb of RAM holds test vectors or trace buffers, and the 147 I/O pins provide plenty of stimulus/observation channels for logic analyzer hookups. Compared to simulation, FPGA prototyping runs at MHz rather than kHz and catches timing bugs that simulation misses. The PQFP-208 package, although obsolete in 2026, is still preferred in academic and defense prototyping labs because it accepts standard 0.5 mm-pitch test clips that BGA parts cannot.
추천
Legacy Glue Logic Replacement
The EPF10K30EQC208-1X excels as a single-chip replacement for legacy 74-series glue logic in mature equipment, where it can absorb 20-50 SSI/MSI logic parts along with custom state machines. Its 1,728 logic elements, 4 embedded array blocks, and 147 I/O pins handle address decoding, bus arbitration, wait-state generation, and interrupt controllers in a single package. The 2.5 V core / 3.3 V I/O voltage compatibility matches 3.3 V ASICs and 5 V-tolerant peripherals of the early 2000s. Compared to designing a fresh ASIC, this approach costs a fraction of the NRE and ships in weeks instead of quarters. Maintainers of telecom, medical, and military equipment rely on this part for end-of-life repair, and Rochester Electronics stocks it specifically for that purpose.
추천
Test and Measurement Instrumentation
The EPF10K30EQC208-1X is well suited to legacy bench instruments (oscilloscopes, logic analyzers, arbitrary waveform generators) where its 30K-gate fabric implements custom DSP pre-processing, channel multiplexing, and display refresh logic in a single chip. The 24 Kb of embedded RAM holds calibration coefficients and waveform lookup tables, and the 147 I/O pins can directly drive front-panel keypads, segment LCDs, or VGA display controllers. The PQFP-208 package simplifies hand rework when lab technicians service instruments; BGA parts cannot be repaired without specialized equipment. Compared to a DSP + microcontroller pair, the FLEX 10KE fabric executes sample-rate conversion and triggering algorithms with deterministic latency, which is critical for measurement accuracy.

설계 노트
Estimated: EPF10K30EQC208-1X requires a clean 2.5 V core (VCCINT) and a 3.3 V I/O supply (VCCIO). Multiple VCCINT and VCCIO pins are distributed around the 208-PQFP package to reduce inductance; place one 0.1 uF decoupling capacitor per VCCINT pin and one 10 uF bulk capacitor near each supply cluster. The 2.5 V rail tolerance is 5% (2.375 V to 2.625 V); use a low-dropout regulator such as an LT1585 or TPS7A45 to keep ripple under 50 mVpk during configuration bursts. Sequence VCCINT before VCCIO per the FLEX 10KE datasheet to avoid I/O latch-up during power-up.
The 208-pin BFQFP has a 0.5 mm pin pitch and a 28x28 mm body; allocate at least 4-layer PCB with a continuous ground plane beneath the device to provide a low-impedance return path for the high-edge-rate configuration and clock signals. Route JTAG signals (TCK, TMS, TDI, TDO) as a daisy chain with 10 kohm pull-ups on TCK/TMS/TDI, and add a 33 ohm series resistor on TDO near the FPGA to damp ringing. Avoid running switching signals (clock, configuration) parallel to user I/O for more than 500 mil to minimize crosstalk into the analog-sensitive I/O banks.
Do not assume the EPF10K30EQC208-1X has on-chip non-volatile memory; this part is SRAM-based and loses its configuration when power is removed. Always pair it with a configuration EEPROM (EPC2 or EPC8) or a microcontroller that streams the bitstream at power-up via passive serial mode. Avoid using the device at junction temperatures above 125 C; the commercial 0 C-70 C rating assumes the case temperature stays within that range, which requires a thermal pad or copper pour in still-air designs. Finally, when substituting EPF10K30EQC208-1N for the -1X, verify that the design's worst-case timing paths still close at the standard speed grade.
