EPF10K30AQC208-1N 概要
A Field Programmable Gate Array (FPGA) is a type of integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic. FPGAs sit in the programmable-logic hierarchy above PLDs/CPLDs and below fixed-function ASICs, and are widely used for glue logic, prototyping, DSP, and high-speed interface bridging. The FLEX 10KA family from Altera was the industry's first embedded programmable logic family providing System-on-a-Programmable-Chip (SOPC) integration through an embedded array block (EAB) architecture, allowing designers to mix dedicated RAM/ROM with LUT-based logic on a single die.
Key features of the EPF10K30AQC208-1N include 1,728 logic elements, 12 Kbits of embedded memory, 147 user I/Os, an internal frequency up to 80 MHz, and SRAM-based configuration that supports rapid prototyping and field updates. The '-1N' speed grade targets the commercial temperature range with standard timing closure. The 208-PQFP surface-mount package uses gull-wing leads, making it compatible with conventional SMT assembly lines and rework processes.
The FLEX 10KA architecture combines a coarse-grained Embedded Array Block (EAB) used to implement memory and complex arithmetic functions with a fine-grained Logic Array Block (LAB) used for general-purpose logic. The EPF10K30A places 6 EABs alongside 216 LABs on a 0.42 µm CMOS process, with each LAB containing 8 LEs. This hybrid fabric is efficient for datapath-heavy designs where distributed RAM and lookup tables coexist.
Typical applications for the EPF10K30AQC208-1N include telecom interface bridging, industrial control glue logic, legacy peripheral bus adaptation (PCI, ISA, VME), high-speed prototyping of ASIC replacements, and embedded memory buffering. Its 3.3 V core, 147 user I/Os, and SRAM programmability also make it attractive for educational platforms and FPGA training kits where the PQFP package simplifies hand-soldering.
Designers should plan a 3.3 V rail with adequate decoupling, route 147 user I/Os across four I/O banks with consistent bank voltage references, and select the correct configuration device (EPC2 or compatible) for SRAM configuration at power-up. Compared to modern flash-based FPGAs, the EPF10K30AQC208-1N requires an external configuration memory and is not 5 V tolerant on I/Os at the core's 3.3 V CMOS levels.
This page synthesizes distributor stock levels, cross-family FLEX 10KA drop-in options, application-specific companion parts, and practical design notes that go beyond what the original Altera datasheet provides alone.

主な用途
EPF10K30AQC208-1N の用途: 6 件s: Telecom Interface Bridging, Industrial Control Glue Logic, Legacy Peripheral Bus Adaptation, ASIC Prototyping Platform, Embedded Memory Buffer / Datapath Engine, FPGA Education and Training Platforms.
Telecom Interface Bridging
The EPF10K30AQC208-1N's 1,728 logic elements and 147 user I/Os make it a good fit for telecom interface bridging applications where E1/T1 or legacy serial buses must be adapted to modern framers or backplane connectors. The 12 Kbits of embedded RAM, distributed across 6 EABs, are sufficient for small FIFO buffers used in rate-adaptation logic. With 80 MHz internal frequency and 0.6 ns propagation delay, the device meets the timing budget of TDM (time-division multiplexing) interfaces at 8.192 MHz and lower. Commercial 0 °C to 70 °C temperature grade matches typical indoor telecom-closet operating ranges. Designers typically pair the FPGA with an EPC2 or EPC4 configuration memory and place 33 Ω series-termination resistors on the 147 user I/Os to control edge rates.
おすすめ
Industrial Control Glue Logic
In industrial control systems, the EPF10K30AQC208-1N serves as flexible glue logic between microcontrollers, motor drivers, and sensor arrays. The 147 user I/Os distributed across multiple I/O banks handle parallel sensor buses and PWM lines, while 12 Kbits of embedded RAM implement lookup tables for sensor linearization and PID coefficients. The 208-PQFP package is friendly to conventional SMT assembly lines used in industrial PCBA. At 3.3 V supply, the device fits modern low-power industrial designs, but engineers should add external level-shifters when interfacing 5 V logic, because the EPF10K30AQC208-1N I/Os are not 5 V tolerant. The FLEX 10KA hybrid EAB+LAB architecture is well suited to combinational control logic mixed with small RAM-based state machines.
おすすめ
Legacy Peripheral Bus Adaptation
The EPF10K30AQC208-1N is widely deployed in legacy peripheral bus adapters that bridge ISA, VME, PCI, or PC/104 buses to modern peripheral chipsets. With 1,728 LEs and 12 Kbits of RAM, the device comfortably fits a 32-bit bus arbiter plus DMA state machine in a single FPGA. The 208-PQFP's 147 user I/Os provide enough pins for full 32-bit address and 32-bit data buses plus parity and sideband signals. The 0.6 ns propagation delay and 80 MHz fMAX support PCI 33 MHz clock-domain timing with margin. For long-lifecycle industrial retrofits, the commercial temperature grade and RoHS3 compliance of the 'N' suffix simplify inventory management. This role is increasingly common in industrial-automation retrofits where legacy controllers must connect to modern sensors.
おすすめ
ASIC Prototyping Platform
For ASIC prototyping in 2026, the EPF10K30AQC208-1N remains a useful FLEX 10KA target for designs originally architected for the 30K-gate class. The 1,728 logic elements and 6 EABs (12 Kbits of RAM) mirror the typical ASIC prototyping envelope of small glue-logic ASICs, allowing RTL verification on real hardware. Engineers use the 208-PQFP for easy probing and logic-analyzer attachment during bring-up. The SRAM-based configuration lets iterations complete in seconds via the Altera ByteBlaster or USB-Blaster programming chain. However, the 80 MHz fMAX ceiling is a constraint for very high-speed designs - in those cases engineers typically move to multiple FLEX 10KA devices or step up to a modern Cyclone IV prototype board.
おすすめ
Embedded Memory Buffer / Datapath Engine
The six EABs in the EPF10K30AQC208-1N total 12 Kbits of dual-port RAM that can be partitioned into independent FIFOs, lookup tables, or small CAM blocks. This makes the device a good fit as a dedicated embedded memory buffer or small datapath engine feeding a downstream DSP or microcontroller. At 80 MHz internal frequency, the EABs support synchronous FIFO depths up to 2 Kbits per block with full read/write clock-domain independence. The 147 user I/Os accommodate a 16-bit datapath plus control signals, while the 0.6 ns propagation delay ensures register-to-EAB timing closes at 80 MHz with margin. Designers typically use the FLEX 10KA architecture to consolidate what would otherwise be two SRAM chips plus a CPLD into a single FPGA.
おすすめ
FPGA Education and Training Platforms
The EPF10K30AQC208-1N's 208-PQFP package is hand-solder-friendly and well supported by low-cost Altera programming tools, making it a popular FPGA for university curricula and training kits. With 1,728 LEs and 147 user I/Os, students can implement meaningful projects ranging from 8-bit CPUs to UART controllers and VGA generators. The 0 °C to 70 °C commercial temperature range matches typical lab environments. Educational boards typically include an EPC2 or EPC4 configuration memory, a 50 MHz oscillator, push-buttons, LEDs, and a 7-segment display. While newer Cyclone IV boards offer more logic capacity, instructors continue to choose the EPF10K30AQC208-1N for courses where the historical FLEX 10KA toolchain and Verilog/VHDL examples are still part of the syllabus.

設計ノート
EPF10K30AQC208-1N requires a clean 3.3 V ±10% supply on VCCINT pins. Place 100 nF ceramic decoupling capacitors as close as possible to each VCCINT/GND pair, with bulk 10 µF tantalum or polymer caps on each supply rail. During configuration the device draws surge currents up to ~300 mA; the EPC2 or EPC4 configuration memory should share the same 3.3 V rail. A power-on-reset circuit is recommended to keep nCONFIG held low until the rail stabilizes. Estimated steady-state core current at 80 MHz with 50% LE toggle is approximately 200 mA, plus I/O contribution proportional to switching frequency.
The 208-PQFP package requires a 28x28 mm land pattern with 0.5 mm pitch gull-wing leads. Use a 4-layer PCB with continuous power and ground planes directly under the device; via stitching every 5 mm around the perimeter suppresses EMI from the 147 I/Os. Keep all 147 user I/O traces short (< 50 mm) and add 22-33 Ω series termination on high-speed outputs to control edge rates. Configuration pins (DCLK, DATA, nCONFIG, nSTATUS, CONF_DONE) should be routed as short stubs to the EPC2/EPC4 configuration memory. Provide a JTAG header (TCK, TMS, TDI, TDO, TRST) for in-system programming via ByteBlaster or USB-Blaster.
Common pitfalls when designing with EPF10K30AQC208-1N: (1) I/Os are NOT 5 V tolerant at 3.3 V VCCIO - external level-shifters are required for 5 V buses; (2) configuration data is volatile and lost at power-down - external EPC2/EPC4 is mandatory; (3) the '-1N' suffix is lead-free only - legacy SnPb builds use EPF10K30AQC208-1; (4) JTAG chain must include the EPC configuration memory in series for in-system programming; (5) VCCIO bank voltages must match connected peripherals or use internal clamping. Estimated thermal dissipation at full activity is ~0.7 W, well within the PQFP package's ~50 °C/W θJA rating.
