EPF10K30AQC208-3N Обзор

The Intel / Altera EPF10K30AQC208-3N is a member of the FLEX 10KA family of SRAM-based Field-Programmable Gate Arrays (FPGAs) integrating 30,000 typical gates, 1,728 logic elements (cells) and 12,288 bits of embedded memory into a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. Built on a 0.3 µm CMOS process and supplied from a 3.3 V core, the device delivers up to 125 MHz of system performance and exposes 147 user I/O pins for digital interfacing. The “-3” speed grade and the “N” lead-free suffix confirm commercial temperature operation and Pb-free assembly, while the “QC208” package code denotes the 208-pin QFP outline used across the FLEX 10KA density range.

A Field-Programmable Gate Array (FPGA) is a semiconductor device whose logic function is defined by user-loaded configuration memory rather than hard-wired mask layers. FPGAs sit in the programmable-logic hierarchy between simple Complex Programmable Logic Devices (CPLDs) and high-density Application-Specific Integrated Circuits (ASICs), giving engineers hardware-reconfigurable glue logic, datapath acceleration, and bus-interface bridging without any NRE charges. The FLEX 10KA family was Intel / Altera’s first generation to embed dedicated array blocks (EABs) for efficient RAM and DSP megafunctions, marking the transition from pure glue logic to System-on-a-Programmable-Chip (SOPC) integration.

Key features of the EPF10K30AQC208-3N include 216 Logic Array Blocks (LABs) organised in rows and columns, embedded array blocks for dual-port RAM and ROM, MultiVolt I/O allowing mixed-voltage interfacing on the same die, pin-controlled PCI-clamping diodes, slew-rate control, and open-drain output options. The PLICE antifuse-style configuration scheme is replaced here by an SRAM configuration cell, supporting in-system reconfigurability via the serial or parallel configuration port. The exposed MultiVolt interface simplifies bridging between 3.3 V cores and 5.0 V or 2.5 V peripherals.

Typical applications include PCI bus controllers, telecommunications line cards, industrial glue logic, protocol bridging (UART, I²C, SPI bridges), legacy ASIC replacement, and parallel DSP datapath prototyping. The combination of 12 Kbit embedded memory, 147 I/Os and 125 MHz Fmax makes it well-suited to mid-density control-plane designs where cost per gate dominates over raw performance.

When designing with this part, allocate the configuration PROM or microcontroller interface early in the schematic because FLEX 10KA devices do not retain their configuration when power is removed. The MultiVolt VCCIO rail must be tied before or simultaneously with VCCINT to avoid latch-up. Use the Quartus / MAX+PLUS II Legacy device libraries and observe the 208-PQFP thermal envelope (θJA ≈ 35 °C/W typical) when calculating airflow in dense line-card layouts.

This page synthesises distributor pricing, drop-in same-package alternatives and practical design notes that go beyond the marketing datasheet, so procurement engineers and FPGA designers can make a confident selection.

Типичное применение

EPF10K30AQC208-3N подходит для 6 применениеs: PCI Bus Interface Controller, Telecommunications Line Card Glue Logic, Industrial Control and Machine I/O Bridging, Legacy ASIC Replacement and Mask-Set Rescue, Parallel DSP Datapath Prototyping, Test & Measurement Front-End Logic.

🌐

PCI Bus Interface Controller

The EPF10K30AQC208-3N’s 30K gate capacity and 147 user I/Os are well matched to PCI 2.2 bus controllers and target/initiator bridges. With 125 MHz Fmax in the -3 speed grade, the device comfortably meets the 33 MHz PCI clock requirement while leaving room for state machines, FIFOs and sideband control logic. Designers typically implement the PAR/REQ/GNT logic, address decoding, and configuration-space registers inside the FPGA, then pair it with a 3.3 V 5 V-tolerant MultiVolt I/O bank to talk to legacy PCI slots. The on-chip 12,288-bit RAM is sufficient for small transaction FIFOs without resorting to external SRAM. The PQFP-208 footprint keeps the design retrofit-compatible with existing line-card layouts.

🌐

Telecommunications Line Card Glue Logic

Telecom line cards often need dozens of bus bridges, framer interfaces and timing-recovery glue, and the EPF10K30AQC208-3N is purpose-built for this role. Its 216 LABs and 1,728 logic elements provide enough capacity to bridge between T1/E1 framers, HDLC controllers and TDM backplanes, while the 147 I/Os let designers route wide parallel buses without external transceivers. The 125 MHz system clock supports 77.76 MHz STS-3 tributary rates with margin, and MultiVolt I/O enables direct interfacing to legacy 5 V framers alongside modern 3.3 V ASICs. The commercial temperature grade covers central-office deployments, while the EPF10K30AQI208-3N sibling covers outdoor enclosures.

🏭

Industrial Control and Machine I/O Bridging

Factory automation controllers frequently require a programmable bridge between PLC backplanes, sensor arrays and motor-drive front ends, and the EPF10K30AQC208-3N provides the right mix of I/O count and logic density. With 147 I/Os the device can fan out to dozens of 24 V opto-isolated inputs and PWM outputs while still implementing custom protocol stacks such as Modbus RTU, CANopen or EtherCAT slave logic. The 3.3 V core combined with MultiVolt I/O banks allows mixed interfacing with 5 V legacy sensors and 2.5 V modern MCUs. Engineers can prototype deterministic control loops on the FPGA fabric and migrate to a structured ASIC once volume justifies NRE.

🔧

Legacy ASIC Replacement and Mask-Set Rescue

When a mature ASIC goes end-of-life, the EPF10K30AQC208-3N is a proven drop-in replacement platform because its 30K gate capacity matches many 1990s-era gate-array designs. Engineers port the RTL to the FLEX 10KA fabric using MAX+PLUS II or Quartus legacy device libraries, then load the bitstream through the standard EPC configuration PROM chain. The 208-PQFP footprint aligns with the original ASIC land pattern on most legacy boards, eliminating expensive PCB rework. The 12 Kbit embedded RAM covers the FIFO and register-file needs of typical glue-logic ASICs, and the MultiVolt I/O eases migration from 5 V-only ASICs to mixed-voltage systems.

📺

Parallel DSP Datapath Prototyping

Before committing to a structured ASIC, algorithm designers often prototype high-throughput DSP datapaths on FPGAs, and the EPF10K30AQC208-3N delivers adequate fabric and I/O bandwidth for filter and FFT pipelines up to a few MHz of sample rate. The 12,288 bits of distributed RAM provide coefficient storage for FIR filters, while the 1,728 logic elements are sufficient for 16-bit MAC arrays and address generators. At 125 MHz, the device sustains 250 MOPS for 16-bit fixed-point datapaths, suitable for audio, motor-control and instrumentation front ends. The MultiVolt I/O banks make it easy to interface to existing ADCs and DACs on the prototype board.

🖥️

Test & Measurement Front-End Logic

Bench instruments such as logic analysers, protocol exercisers and production ATE fixtures use mid-density FPGAs to capture, multiplex and timestamp high-speed signals, and the EPF10K30AQC208-3N is a strong fit. Its 147 I/Os handle 32- or 48-channel acquisition buses, while the 125 MHz fabric implements state machines for trigger sequencing, pattern generation and pass/fail comparison. The MultiVolt I/O allows the same FPGA to interface to 1.8 V, 2.5 V, 3.3 V and 5 V targets without level shifters, simplifying fixture design. The 12 Kbit embedded RAM provides elastic buffer storage for asynchronous sample streams.

The EPF10K30AQC208-3N is an Intel / Altera FLEX 10KA family SRAM-based FPGA with 1,728 logic elements, 12,288 bits of embedded RAM, 147 user I/Os and 30K typical gates, packaged in a 208-pin PQFP (BFQFP) and rated for 125 MHz operation at commercial temperature. According to the Altera FLEX 10KA datasheet, the part is supplied from a 3.3 V core and uses a 0.3 µm CMOS process.
How many I/O pins does the EPF10K30AQC208-3N have?
The EPF10K30AQC208-3N provides 147 user I/O pins on its 208-pin PQFP package, with the remaining pins dedicated to supply (VCCINT, VCCIO, GND), JTAG (TDI, TDO, TMS, TCK), configuration (nCONFIG, nSTATUS, CONF_DONE, DCLK) and MultiVolt reference. The 147 I/Os each support MultiVolt interfacing so they can be driven by 2.5 V, 3.3 V or 5.0 V peripherals.
What supply voltage does the EPF10K30AQC208-3N require?
The EPF10K30AQC208-3N requires a 3.3 V core supply (VCCINT) and supports a separate VCCIO rail for the MultiVolt I/O banks, which may be tied to 2.5 V, 3.3 V or 5.0 V depending on the peripherals being driven. According to the FLEX 10KA datasheet, VCCIO must be applied before or simultaneously with VCCINT to prevent latch-up during power-up.
What is the maximum operating frequency of EPF10K30AQC208-3N?
The EPF10K30AQC208-3N is a -3 speed grade device and supports system frequencies up to 125 MHz under commercial temperature conditions. Actual Fmax depends on the design’s logic depth, routing and I/O standard; the 125 MHz figure is the datasheet ceiling for internal flip-flop toggling with typical interconnect.
Where can I buy the EPF10K30AQC208-3N today?
As of 2026-09-11, the EPF10K30AQC208-3N is listed as obsolete by Altera (Intel FPGA) and is available only from authorised distributors and the open market. Current stock and pricing are visible on DigiKey (page 1084760), Mouser, Arrow and Octopart, with lead times typically 4-12 weeks for new factory stock and immediate shipment from broker inventory.
What is the price of the EPF10K30AQC208-3N?
Pricing as of 2026-09-11 from open-market distributors starts around USD 38.50 per unit at qty-1 and decreases to roughly USD 19.10 per unit at qty-1000. Exact distributor quotes vary daily because the part is end-of-life and most stock is held by brokers; contact DigiKey, Mouser or Arrow for a live quote on your required quantity.
Is the EPF10K30AQC208-3N in stock and what is the lead time?
Stock levels fluctuate sharply because the part is obsolete. DigiKey page 1084760 typically lists 50-300 units with immediate shipment, while larger qty-1000 orders are pulled from broker or factory-lot inventory with 4-12 week lead times. Always confirm availability on the distributor’s live inventory page before placing a production order.
What is the difference between EPF10K30AQC208-3N and EPF10K30AQC208-3?
The EPF10K30AQC208-3 and EPF10K30AQC208-3N share the same die, package (208-PQFP) and speed grade (-3); the only difference is the N lead-free finish versus a SnPb finish on the non-N variant. Both parts are functionally identical, but the N suffix guarantees Pb-free assembly for RoHS-compliant products.
What is the best drop-in replacement for EPF10K30AQC208-3N in the same 208-PQFP package?
Pin-compatible drop-in replacements in the 208-PQFP include EPF10K30AQC208-3 (SnPb finish, same die) and EPF10K30AQC208-2N (slower -2 speed grade, same die and pinout). Both fit the same land pattern and accept identical configuration bitstreams, so no PCB rework is needed. For higher density or newer features, the FLEX 10KE family (e.g., EPF10K30EFC484) requires a different package and is not a drop-in.
Can the EPF10K30AQI208-3N replace the EPF10K30AQC208-3N?
The EPF10K30AQI208-3N is an industrial-temperature variant in the same 208-PQFP package and is generally pin-to-pin compatible with the commercial EPF10K30AQC208-3N. The I-suffix expands the operating range to -40 °C to +85 °C and uses a slightly different thermal grade, but the configuration bitstream is the same, so it can serve as a drop-in replacement in most cases. Always verify MultiVolt I/O bank assignments against the original design.
Where can I download the EPF10K30AQC208-3N datasheet PDF?
The Altera FLEX 10KA datasheet covering the EPF10K30AQC208-3N is mirrored at https://www.alterasemi.com/datasheet/alterasemi/EPF10K30AQC208-3.pdf, and the original is also available through the Intel FPGA legacy device archive. The PDF contains DC characteristics, AC timing, MultiVolt I/O behaviour, pin tables for the 208-PQFP, and configuration interface schematics.
Where can I find the EPF10K30AQC208-3N pinout?
The complete 208-PQFP pinout is published in the FLEX 10KA datasheet and reproduced in the Altera Quartus II legacy device library (package code QC208). User I/Os are organised into four I/O banks (each with its own VCCIO pin), and the configuration, JTAG, and power pins are documented in the same datasheet chapter.
What key specifications of EPF10K30AQC208-3N should engineers know?
Engineers should know three headline numbers: 1,728 logic elements (cells), 12,288 bits of embedded RAM and 125 MHz maximum operating frequency. According to the Altera FLEX 10KA datasheet, the part also offers 147 user I/Os, 216 LABs, 3.3 V core supply with MultiVolt I/O support, and is housed in a 208-pin PQFP (BFQFP) for surface-mount assembly.
Is there an Xilinx equivalent for the EPF10K30AQC208-3N?
Cross-brand pin-compatible equivalents do not exist because Altera FLEX 10KA and Xilinx Spartan / XC4000 architectures use different package pin assignments. The closest Xilinx alternative by logic capacity is the XC4013XL or Spartan-XL family, but these require PCB rework because the 208-PQFP pinout differs. Engineers migrating between vendors typically need to re-layout the board and port the HDL.

Руководство по выбору

Choose the EPF10K30AQC208-3N when your design needs 30K gates and 1,728 logic elements in a 208-PQFP package and must operate at the highest commercial-temperature speed grade (125 MHz Fmax) on a RoHS-compliant lead-free assembly line. Pick the EPF10K30AQC208-3 if you have a SnPb-compatible reflow process and want a small cost saving; choose the EPF10K30AQC208-2N or -1N when the design is well within timing margin and you prefer slower grades for cost or power reasons. Pick the EPF10K30AQI208-3N when your deployment spans -40 C to +85 C industrial environments. Choose the EPF10K10AQC208-3N only as a cost-down option when your design fits within 10K gates. Cross-brand drop-in equivalents (e.g., Xilinx) do not exist in this footprint; cross-vendor migration requires PCB rework.

Заметки по проектированию

The EPF10K30AQC208-3N requires two supply rails: a 3.3 V VCCINT for the core logic and a separate VCCIO (per I/O bank) for the MultiVolt interface. According to the Altera FLEX 10KA datasheet, VCCIO must reach its operating level before or simultaneously with VCCINT during power-up to prevent the I/O buffers from back-powering the core through ESD diodes. Decouple each VCCINT pin with a 0.1 µF ceramic plus a 10 µF tantalum bulk cap, and place 0.1 µF ceramics on every VCCIO pin within 5 mm of the package.

Because FLEX 10KA devices are SRAM-based, they lose configuration when power is removed. A non-volatile configuration source (Altera EPC8QC100 serial PROM, parallel byte-wide flash, or a microcontroller) must be connected to the configuration interface (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0). For JTAG programming, tie TMS and TDI high through 10 kΩ pull-ups and use a JTAG header compatible with Altera ByteBlaster or USB-Blaster download cables.

Estimated: at maximum utilisation, the 208-PQFP package dissipates roughly 1.5-2.0 W. With a typical theta_JA of 35 °C/W on a 4-layer JEDEC test board, the junction rises 50-70 °C above ambient. For continuous full-load operation, provide at least 200 LFM of airflow or attach a clip-on heatsink on the package top. Avoid mounting the PQFP in a vertical orientation that traps heat under the leads.

Keep the configuration clock (DCLK) trace short and length-matched to within 25 mm of DATA0 to avoid setup/hold violations at 33 MHz configuration rates. Place the configuration PROM within 50 mm of the FPGA and route its outputs over a continuous ground reference. MultiVolt I/O banks should be grouped on the schematic so that VCCIO pins are tied to a single supply per bank, simplifying the PCB power plane cut-out.

Common pitfalls include (1) forgetting to pull nCONFIG high through 10 kΩ during normal operation, (2) mixing 5 V and 3.3 V signals on the same VCCIO bank, (3) using the non-N finish part on a RoHS-compliant board, and (4) trying to fit more than 147 I/Os in the user I/O budget. Designers should also enable the Quartus / MAX+PLUS II PCI-clamping-diode and slew-rate-control logic options on PCI pins to meet the PCI 2.2 AC specification.
