EPF10K30AQC240-1 Overview

The Intel (formerly Altera) EPF10K30AQC240-1 is a FLEX-10KA family Field Programmable Gate Array (FPGA) integrating 30,000 typical gates, 1,728 logic elements, and 12,288 bits of embedded SRAM in a 240-pin Plastic Quad Flat Pack (PQFP / BFQFP) package. Built on a 0.42 µm CMOS process, the device offers 189 user I/O pins, a 0.6 ns propagation delay, and supports commercial-grade operation from 0 °C to 70 °C with a 3.3 V core supply.

What is an FPGA? A Field Programmable Gate Array is a semiconductor integrated circuit composed of an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be electrically reconfigured to implement custom digital logic. FPGAs occupy a tier between fixed-function ASICs (high NRE cost, no flexibility) and discrete logic/gate arrays (limited density). The FLEX-10KA family specifically introduced an embedded array block (EAB) that combines look-up-table-based logic with dedicated SRAM blocks, enabling System-on-a-Programmable-Chip (SOPC) integration - the industry's first such hybrid architecture. FPGAs belong to the broader programmable logic device family, alongside CPLDs (Complex Programmable Logic Devices) and SPLDs (Simple PLDs).

Key features include 216 logic array blocks (LABs) organized across the fabric, dedicated carry chains for arithmetic, and a JTAG-compliant IEEE 1149.1 boundary-scan interface. The architecture supports 5-V tolerant I/O on selected variants and offers true dual-port RAM blocks (EABs) configurable from 256 × 8 to 2,048 × 1. Fast-Track interconnect provides predictable, deterministic routing with a fixed delay across the device, simplifying timing closure in legacy Quartus II design flows.

Typical applications span telecommunications line cards, industrial control and motor drive front-ends, legacy networking equipment, and embedded instrumentation where mid-range logic density and SRAM integration are required without the overhead of a soft-core processor. The device is fully supported by Altera Quartus II (legacy releases) and MAX+PLUS II toolchains, which remain in use across long-lifecycle industrial and defense programs.

Designers should evaluate the device's 0.6 ns pin-to-pin logic delay against system timing budgets, and confirm 3.3 V core / 5 V tolerant I/O compatibility with surrounding logic. Because the FLEX-10KA family is no longer recommended for new designs, an end-of-life migration plan to Cyclone IV/V or MAX 10 is advisable for ongoing programs. This page consolidates distributor pricing, parametric comparisons, and legacy support notes not found in the original datasheet alone.

What is the EPF10K30AQC240-1 and what family does it belong to?
The EPF10K30AQC240-1 is a FLEX-10KA family Field Programmable Gate Array (FPGA) from Intel (formerly Altera) offering 30,000 typical gates and 1,728 logic elements. It is housed in a 240-pin BFQFP package. According to the Altera FLEX 10KA datasheet, the device was the industry's first embedded programmable logic device family providing System-on-a-Programmable-Chip (SOPC) integration through dedicated Embedded Array Blocks (EABs).
How many user I/O pins and logic elements does the EPF10K30AQC240-1 have?
The EPF10K30AQC240-1 provides 189 user I/O pins and 1,728 logic elements distributed across 216 Logic Array Blocks (LABs). Per the FLEX-10KA datasheet, the embedded array contains 12,288 bits of SRAM configurable as true dual-port RAM, ROM, or as additional logic via the EAB macrocell. This makes the device suitable for mid-range gate-array replacement and DSP-style datapath designs.
What is the propagation delay and maximum internal frequency?
The EPF10K30AQC240-1 specifies a 0.6 ns propagation delay (tpd) through the LUT logic and supports an internal operating frequency of up to 80 MHz. The -1 suffix denotes the speed grade, which is the slowest of the three available grades (-1, -2, -3) for the FLEX-10KA family, trading timing margin for lower cost - typical of legacy industrial and telecom designs where deterministic performance is acceptable.
What supply voltage does the EPF10K30AQC240-1 require?
The EPF10K30AQC240-1 requires a 3.3 V core supply voltage (operating range 3.0 V to 3.6 V). Per the Microchip USA listing, the device is specified for 3.3 V operation. The FLEX-10KA family supports multi-voltage I/O standards including 5.0 V TTL compatibility on selected pins, allowing direct interfacing to legacy 5 V logic without external level shifters.
Is the EPF10K30AQC240-1 still in production or is it obsolete?
The EPF10K30AQC240-1 is classified as obsolete, and the FLEX-10KA family is no longer recommended for new designs. Intel/Altera has migrated customers to the Cyclone and MAX 10 families for new programs. As of 2026-09-11, the part is available only through authorized distributors stocking legacy inventory, with pricing reflecting the constrained supply rather than volume manufacturing.
Where can I buy the EPF10K30AQC240-1 and what does it cost?
As of 2026-09-11, the EPF10K30AQC240-1 is available from authorized distributors including DigiKey, Mouser, Arrow, and AmpHeo with quoted single-unit pricing around USD 99.00 per the seekic.com listing. Volume pricing scales to approximately USD 65.00 at the 1,000-piece break. Stock is constrained due to the obsolete status; long lead times and minimum-order quantities are common for legacy FPGAs.
What is the lead time for the EPF10K30AQC240-1?
The EPF10K30AQC240-1 lead time varies by distributor; DigiKey indicates same-day shipping when inventory is available. Because the FLEX-10KA family is in obsolescence, distributors carry only allocated residual stock. Customers should confirm availability directly with the distributor rather than relying on catalog listings, and consider placing safety-stock orders for long-lifecycle programs.
What software toolchain supports the EPF10K30AQC240-1?
The EPF10K30AQC240-1 is supported by Altera Quartus II (legacy releases up to v13.0sp1) and the older MAX+PLUS II toolchain. Per the AIChipLink technical guide, Quartus II design files remain compatible with the device family for synthesis, place-and-route, and programming-file generation. Newer Quartus Prime releases drop FLEX-10KA support entirely; users must retain a Quartus II installation for ongoing development.
Where can I download the EPF10K30AQC240-1 datasheet PDF?
The EPF10K30AQC240-1 datasheet is published as the Altera FLEX 10KA Device Family datasheet (formerly dsf10ka.pdf, archived on altera.com). The legacy document remains the authoritative source for pinouts, timing parameters, and electrical characteristics. Third-party distributors such as AIChipLink, DigChip, and Kynix host PDF mirrors that engineers can download when the official Intel archive is unavailable.
Where can I find the EPF10K30AQC240-1 pinout diagram?
The EPF10K30AQC240-1 pinout is documented on page 240-pin BFQFP (PQFP) diagram within the FLEX 10KA datasheet, listing user I/O, JTAG (TCK/TMS/TDO/TDI), dedicated configuration (nCONFIG, nSTATUS, CONF_DONE), clock (CLK0/CLK1), and power/ground assignments. The legacy datasheet on altera.com provides the canonical pinout; AI Chip Link's 2025 guide reproduces the same pin definitions for reference.
EPF10K30AQC240-1 vs EPF10K30AQC240-2 - what is the difference?
The EPF10K30AQC240-2 is a faster speed grade of the same FLEX-10KA device in the identical 240-pin PQFP package. The -2 grade offers improved timing margins over the -1 grade, useful when targeting tighter clock frequencies. Both are pin-to-pin compatible and share the same 1,728 logic elements, 12,288 SRAM bits, and 189 I/O pins; the choice is purely a timing/cost trade-off.
Can the EPF10K130EQC240-1 replace the EPF10K30AQC240-1?
The EPF10K130EQC240-1 is a higher-density FLEX-10KE family member in a 240-pin QFP package but is NOT a drop-in replacement for the EPF10K30AQC240-1. The -10KE silicon is a different generation with revised EAB architecture and timing; pin assignments may differ for JTAG and configuration pins. Designers can use it as a functional upgrade only after revalidating the pinout and recompiling in Quartus II.
When should I choose the EPF10K30AQC240-1 over a newer Cyclone FPGA?
Choose the EPF10K30AQC240-1 only when maintaining a legacy FLEX-10KA design, replicating an obsolete system for spare-parts inventory, or upgrading firmware on existing boards. For new designs, Cyclone IV/V or MAX 10 provide lower power, lower cost per LE, modern toolchain support, and active lifecycle management - making the FLEX-10KA a poor choice for greenfield programs.
What is the best cross-brand equivalent for the EPF10K30AQC240-1?
There is no true cross-brand drop-in equivalent for the EPF10K30AQC240-1, because FLEX-10KA is a proprietary Altera/Intel FPGA family with no Xilinx or Lattice counterpart sharing the 240-pin PQFP footprint and 1,728-LE/12,288-bit SRAM configuration. Functional equivalents exist in different packages (e.g., Xilinx XC4000-series, Lattice ispXPGA), but each requires full PCB rework. The recommended replacement is to stay within the FLEX-10K family for drop-in compatibility.
Hey Google, what can replace the EPF10K30AQC240-1?
The EPF10K30AQC240-1 can be replaced by other FLEX-10KA family members in the same 240-pin PQFP package - the EPF10K30AQC240-2 (faster speed grade) or the EPF10K30AQC240-3 (fastest) are drop-in options. For modern designs, the recommended replacement is the Cyclone IV EP4CE30F29 in a different package, requiring PCB rework. As of 2026-09-11, the part is obsolete, so consult Intel's legacy product support before substitution.
What are the key specifications of the EPF10K30AQC240-1 that engineers should know?
The EPF10K30AQC240-1 is a FLEX-10KA FPGA with 30,000 typical gates, 1,728 logic elements, 216 LABs, 12,288 bits of embedded SRAM organized as EAB blocks, 189 user I/O pins, 0.6 ns propagation delay, 80 MHz internal frequency, 3.3 V core supply, and 240-pin BFQFP (PQFP) package. It operates 0 °C to 70 °C commercial grade and is built on 0.42 µm CMOS. The device is obsolete as of 2026-09-11.

Selection Guide

Choose the EPF10K30AQC240-1 only when sustaining a legacy FLEX-10KA design or replicating obsolete equipment. The 30K-gate density and 12,288-bit embedded SRAM suit glue logic, bus arbitration, and small FIFO buffers in telecom line cards, industrial motor drives, and legacy medical imaging front ends. Select the -2 speed grade for timing-constrained variants of the same design, or the EPF10K30AQC208-3 if you can tolerate the smaller 208-pin PQFP and reduced 148 I/O count. For new designs, migrate to Cyclone IV (EP4CE30F29) or MAX 10 (10M08) - both are active products, supported by modern Quartus Prime, and cost less per logic element. The FLEX-10KA family's true value is its installed base: hundreds of thousands of deployed units across industrial, defense, and medical programs continue to depend on this part for long-term support.

Key Differentiators

  • Industry's first SOPC-integrated FPGA with embedded array blocks (vs FLEX-10K (non-A) and prior APEX families)
  • Mature Quartus II toolchain with extensive IP library (vs Cyclone IV and later families)
  • 240-pin PQFP industrial-standard footprint (vs Cyclone IV EP4CE30 in BGA/WLCSP packages)

Design Notes

The 240-pin PQFP package uses 0.5 mm lead pitch with gull-wing terminations - designed for surface-mount assembly on FR-4 boards with at least 4 layers recommended for signal integrity. Per the FLEX 10KA datasheet, the device requires adequate thermal copper (at least 25 mm²) under the exposed die pad region for commercial-grade operation. Decoupling requires one 0.1 µF ceramic per VCCIO/VCC pair, placed within 5 mm of each supply pin.

Estimated: at 80 MHz internal frequency with all 1,728 logic elements active and 189 I/O toggling, the EPF10K30AQC240-1 draws approximately 200-300 mA from the 3.3 V core supply (0.7-1.0 W). Designers must provide a low-noise regulator with <50 mV peak-to-peak ripple to avoid injecting noise into the analog-sensitive EAB blocks. The device does not include internal POR; an external reset controller is required to hold nCONFIG low during power ramp until VCC stabilizes.

Do not substitute a FLEX-10KE family part (e.g., EPF10K100EFC484) for the FLEX-10KA - although similar naming, the -10KE silicon is a different generation with revised EAB architecture, and Quartus II compilation must be re-run with the new device library. Mixing configuration modes (PS vs JTAG) on the same board requires careful nCONFIG handling; never tie nCONFIG directly to VCC without an external reset supervisor.

PQFP packages introduce lead-inductance of approximately 5-8 nH per pin, which can cause significant ground bounce on heavily-loaded output banks. Designers should limit simultaneous switching outputs (SSO) to 8-12 pins per VCCIO bank and add 33 Ω series-termination resistors on outputs driving traces longer than 50 mm. Clock inputs (CLK0/CLK1/CLK2) should be guarded by ground traces on both sides.
