EPF10K30EQI208-2N - 30K-Gate FLEX 10KE FPGA, 208-PQFP | Altera
MPN: EPF10K30EQI208-2N ✗ Cuối đờiEPF10K30EQI208-2N Tóm tắt
A field-programmable gate array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs / LABs), programmable interconnect, and configurable I/O cells, all controlled by bits stored in on-chip SRAM. FPGAs are used to implement arbitrary digital logic without the cost and lead-time of an ASIC. Within the broader semiconductor taxonomy, FPGAs sit under programmable logic devices (PLDs) alongside CPLDs, and historically represent the high-density end of that family - capable of holding entire processor subsystems, interface bridges, or DSP pipelines. The FLEX 10KE generation (circa late-1990s) was Altera's mainstream 2.5 V SRAM-based family before the Stratix/Cyclone families replaced it.
Key features of the EPF10K30EQI208-2N include up to 24,576 RAM bits distributed across embedded array blocks, an internal operating frequency around 200 MHz (process-dependent), an industrial temperature grade (-40 °C to +85 °C), and JTAG (IEEE Std 1149.1) boundary-scan support. The 208-pin PQFP exposes 147 user I/Os and supports common single-ended I/O standards of its era (LVTTL, LVCMOS, PCI). SameFrame pin-migration is documented for compatible FLEX 10KE devices in the same package, allowing designers to swap density variants without re-laying the PCB.
Typical applications for this device include industrial control and instrumentation, telecom line-card glue, legacy ASIC prototyping, motor and process control, and embedded DSP front-ends - particularly where existing FLEX 10KE firmware is being maintained or where a second-source-qualified footprint is required. Designers planning new designs are instead routed to the Cyclone or MAX families; this part is therefore of greatest interest on legacy platforms and EOL re-designs.
When designing with the EPF10K30EQI208-2N, note that JTAG and CONFIG_DONE pull-ups and a configuration device (EPC2/EPC4 or compatible) must be provided - the device is SRAM-based and reconfigures on every power-up. Observe the 2.5 V VCCINT supply requirement and provide adequate decoupling around the PQFP perimeter to keep simultaneous-switching-noise (SSN) under control.
This page synthesizes distributor stock and pricing, drop-in-compatible FLEX 10KE alternatives in the same 208-PQFP footprint, and practical design notes that go beyond what the bare datasheet provides - giving procurement, reliability, and design engineers a single decision-ready view of the part.

Ứng dụng tiêu biểu
EPF10K30EQI208-2N phù hợp cho 6 Áp dụngs: Industrial Control & Process Automation, Telecom Line-Card Glue Logic, ASIC Prototyping & Emulation, Legacy DSP / Motor-Control Front-End, Military / Aerospace Retrofit (Legacy Only), Test & Measurement Instrumentation.
Industrial Control & Process Automation
The EPF10K30EQI208-2N is well suited to legacy industrial control backplanes where a 30K-gate fabric plus embedded EAB RAM is enough to implement glue logic, encoder counters, PID state machines, and Modbus / PROFIBUS interface bridges. Its 147 user I/Os absorb ample parallel field-bus signals, while the -40 °C to +85 °C industrial temperature grade handles cabinet and factory-floor environments. Designers integrating on existing FLEX 10KE firmware can reuse the Quartus II bitstream with no re-compile, and SameFrame pin migration allows upward scaling to EPF10K100E or EPF10K130E on the same PCB if logic grows.
Được đề xuất
Telecom Line-Card Glue Logic
The EPF10K30EQI208-2N was a common choice for telecom line-card glue - bus bridges, framing logic, and TDM time-slot switching. The 6 EABs deliver up to 24 Kb of synchronous RAM that can be carved into FIFOs for elastic buffers, while the 200 MHz internal fabric supports high-speed serial-parallel aggregation. The 2.5 V VCCINT and LVTTL/LVCMOS I/O align with the backplane logic levels of late-1990s / early-2000s central-office hardware. Same-die, same-footprint migration to EPF10K100EQI208-2N is supported by SameFrame pin compatibility.
Được đề xuất
ASIC Prototyping & Emulation
The EPF10K30EQI208-2N is still useful as a low-cost prototyping vehicle for legacy ASIC RTL, where 30K gates is enough to validate control paths and bus fabrics before committing to mask tooling. The Quartus II toolchain (now legacy) supports the part, and the 147 I/Os can be partitioned into clean emulation pads. Engineers prototyping mixed designs often chain multiple FLEX 10KE devices in JTAG mode to emulate multi-chip ASICs - the IEEE 1149.1 boundary-scan support on every E and A FLEX 10KE device makes this practical.
Được đề xuất
Legacy DSP / Motor-Control Front-End
The EPF10K30EQI208-2N fits motor-control front-ends where PWM generators, quadrature-decoder state machines, and encoder interfaces are implemented in fabric and pipelined into a downstream DSP. The 24 Kb of distributed EAB RAM supports small coefficient tables and look-up tables used in space-vector modulation, while the 200 MHz fabric comfortably absorbs the 50-200 kHz switching frequency of industrial drives multiplied by the per-edge logic depth. Industrial temperature grading suits closed-loop servo enclosures.
Được đề xuất
Military / Aerospace Retrofit (Legacy Only)
In retrofits of long-lifecycle aerospace and military systems, the EPF10K30EQI208-2N is sometimes still specified because the host platform's firmware and qualification artifacts are tied to the FLEX 10KE bitstream. The device's documented industrial operating range and proven long-term reliability in the field, combined with SameFrame pin migration across FLEX 10KE density points, allow the part to be used as a like-for-like replacement in obsolescence-management programs.
Được đề xuất
Test & Measurement Instrumentation
The EPF10K30EQI208-2N can serve as the timing-and-control fabric inside bench-top instruments - pattern generators, logic-analyzer pre-processors, and protocol exercisers. The 147 I/Os support parallel stimulus/response buses, while the 6 EABs allow per-channel buffering and timing-edge capture. The 200 MHz fabric supports pattern rates commonly required for legacy serial-bus stimulus. For new designs in test-and-measurement, however, modern Cyclone IV/V devices are preferred for cost and power reasons.

Ghi chú thiết kế
The EPF10K30EQI208-2N requires a clean 2.5 V ±5% rail on VCCINT and a separate VCCIO rail (3.3 V or 2.5 V per bank I/O standard). Place 0.1 µF + 10 µF decoupling pairs adjacent to every VCCINT and VCCIO pin and a single 47-100 µF bulk capacitor at the regulator output. Power-up sequencing: VCCINT must reach 2.5 V before or simultaneously with VCCIO to avoid I/O latch-up; both rails must stabilize within 100 ms to satisfy POR timing.
The 208-PQFP package has 0.5 mm pitch leads and a 28 mm × 28 mm body. Use a 4-layer PCB with a continuous ground plane under the device to control simultaneous-switching noise on the 147 I/Os. Route JTAG (TCK/TMS/TDI/TDO/nSTATUS/CONFIG_DONE) as a separate signal group with ground-shielded traces and 10 kΩ pull-ups on nSTATUS, nCONFIG and CONFIG_DONE.
The EPF10K30EQI208-2N is volatile - omitting the EPC2/EPC4 configuration EEPROM leaves the device unconfigured after every power-up. Pull nCONFIG high through 10 kΩ, route DCLK away from noisy I/O, and ensure the bitstream CRC check passes by selecting the Quartus II generated .sof/.pof that targets this exact device. Mixing bitstreams with different device IDs will fail configuration silently.
