Typical Applications

EP1C4F400C6 is suitable for 6 applications: Industrial Control and Glue Logic, Digital Signal Processing Front-End, Video Processing and Display Controllers, Communications Protocol Bridging, Cost-Sensitive Prototype and Evaluation Designs, Legacy Equipment Modernization and Long-Life Programs.

🏭

Industrial Control and Glue Logic

The EP1C4F400C6 is well suited to industrial control and motor-drive glue logic where 4,000 logic elements, 301 user I/Os, and two PLLs provide more than enough capacity for state machines, encoder interfaces, and PWM generation. Its commercial temperature range (0°C to +85°C) covers most factory-floor enclosures with active cooling. The 400-ball BGA enables dense board layouts, while the M4K RAM blocks implement command FIFOs and look-up tables for sensor linearization.

🎧

Digital Signal Processing Front-End

For low-cost DSP front-ends such as audio sample-rate conversion, FIR/IIR filter banks, or simple FFT pre-processing, the EP1C4F400C6's 4,000 LEs and 78 Kbits of embedded RAM provide adequate resources for moderate-complexity algorithms at audio and baseband sample rates. The two PLLs generate the precise clock trees required for ADC/DAC synchronization, and the LVDS-capable I/Os interface directly to common audio and video ADCs without external translators.

📺

Video Processing and Display Controllers

The EP1C4F400C6 is commonly deployed in video format conversion, de-interlacing, and LCD/TFT timing generator designs. Its 301 user I/Os comfortably drive 24-bit RGB plus control and sync signals, while the M4K RAM blocks implement line buffers and color lookup tables. Designers use the LVDS I/O capability to interface directly to LVDS panel inputs, eliminating external serializer components and reducing BOM cost in consumer displays.

🌐

Communications Protocol Bridging

Bridge designs converting between UART, SPI, I2C, parallel buses, and legacy telecom interfaces fit naturally in 4,000 LEs. The EP1C4F400C6's abundant user I/Os (301) make it ideal for multi-channel protocol aggregation, while the M4K blocks buffer packet payloads between asynchronous clock domains. Industrial protocol stacks such as Modbus, Profibus, and CAN glue logic are easily implemented, making this part a common choice for legacy equipment modernization.

🧩

Cost-Sensitive Prototype and Evaluation Designs

Designers building FPGA-based prototypes for ASIC validation, university teaching platforms, or low-volume OEM products appreciate the EP1C4F400C6's balance of capacity and price. Quartus II Web Edition (free) supports the full Cyclone family, eliminating software licensing friction. The 400-ball BGA exposes enough I/Os for daughter-card expansion, and the abundant M4K RAM enables realistic test benches with realistic data buffering requirements.

✈️

Legacy Equipment Modernization and Long-Life Programs

Many defense, aerospace, and medical OEMs have Cyclone I designs that must continue manufacturing for 10-20 year life cycles. Because the EP1C4F400C6 is on Intel's last-time-buy list (as of 2026-09-06), these programs are stockpiling inventory and qualifying drop-in alternatives such as the EP1C4F400C8N and EP1C4F400I7N. These parts share the same die, package, and pinout, allowing form-fit-function continuity without PCB redesign.

What is the logic element count of EP1C4F400C6?
The Intel EP1C4F400C6 contains 4,000 logic elements (LEs) organized into 400 logic array blocks (LABs). According to the Altera Cyclone Family datasheet, each LE consists of a 4-input look-up table, a programmable register, and a dedicated carry chain, giving the device a balanced mix of combinatorial and registered logic for low-cost digital designs.
What package does the EP1C4F400C6 use?
The EP1C4F400C6 ships in a 400-ball FineLine BGA package (designator F400 / 400FBGA). This fine-pitch BGA provides 301 user I/O pins spread across multiple I/O banks, each requiring its own VCCIO supply for mixed-voltage interface support such as LVTTL, LVCMOS, SSTL, and LVDS.
How much embedded memory does the EP1C4F400C6 have?
The EP1C4F400C6 integrates 78 Kbits of embedded RAM implemented as M4K blocks, each 4 Kbits wide with true dual-port and shift-register support. These blocks are commonly used for FIFOs, small lookup tables, and buffer memories in DSP and protocol-bridging applications.
Where can I buy EP1C4F400C6 and what is the approximate price?
As of 2026-09-06, the EP1C4F400C6 is in last-time-buy (LTB) status with Intel, so authorized distributor stock is dwindling. It remains listed on Mouser, Octopart, and several independent distributors; XAIPART offers 1-piece pricing around USD 38.50 with declining tiers at higher quantities. Contact sales for current availability and lead time.
What is the lead time for EP1C4F400C6 today?
Because the EP1C4F400C6 is on last-time-buy, lead times vary widely. As of 2026-09-06, authorized-channel stock is largely depleted; brokers and independent distributors quote 4 to 12 weeks depending on quantity and traceability documentation. Plan a redesign to a Cyclone II/III/IV equivalent if long-term supply assurance is required.
Is EP1C4F400C6 in stock at distributors?
Stock levels as of 2026-09-06 are limited and declining because the part is on last-time-buy. Authorized distributors typically show zero or fractional stock; independent distributors and brokers carry limited inventory. For volume production, transitioning to a Cyclone II, III, IV, or newer Cyclone 10 LP device is strongly recommended.
What is the difference between EP1C4F400C6 and EP1C4F400C8N?
Both parts share the same 400-ball FineLine BGA package and 4,000-logic-element Cyclone die, so they are pin-compatible drop-in alternatives. The EP1C4F400C6 carries a -6 commercial speed grade, while the EP1C4F400C8N is a -8 speed grade and is lead-free (Pb-free / N suffix). In practice, the C8N runs slightly slower but is the preferred choice for new RoHS-compliant builds.
What is the difference between EP1C4F400C6 and EP1C4F324I7N?
The EP1C4F400C6 uses a 400-ball FineLine BGA with 301 user I/Os, while the EP1C4F324I7N uses a 324-pin FineLine BGA with fewer I/Os. They share the same Cyclone die and 4,000-LE fabric, so the logic resources are identical, but the package and ball map differ — this is NOT a drop-in replacement and requires PCB redesign.
When should I choose EP1C4F400C6 over EP1C20F400C6?
Choose the EP1C4F400C6 when your design needs roughly 4,000 logic elements and 78 Kbits of RAM; choose the EP1C20F400C6 when you need the larger 20,060-logic-element Cyclone die in the same 400-ball BGA footprint. Both share the F400 package, but the C20 has roughly 5x the logic capacity, so the C4 is the right pick for cost-sensitive designs that fit comfortably in 4,000 LEs.
What is the best drop-in replacement for EP1C4F400C6?
The best drop-in replacement for the EP1C4F400C6 is the EP1C4F400C8N, which uses the same Cyclone die and 400-ball FineLine BGA package. The only differences are the speed grade (-8 vs -6) and lead-free terminal finish. For long-term supply, migrating to a Cyclone IV EP4CE6F17 or Cyclone 10 LP 10CL006YU256 device is advisable, but those are NOT pin-compatible and require PCB rework.
Can an EP1C4F400C8N replace an EP1C4F400C6?
Yes. The EP1C4F400C8N is a true drop-in replacement for the EP1C4F400C6: same die, same 400-ball FineLine BGA package, same I/O count. Only the speed grade changes (-8 vs -6) and the C8N is lead-free. Timing closure must be re-verified, but functionally and pin-out-wise the swap is safe.
Where can I download the EP1C4F400C6 datasheet PDF?
The official Cyclone Family datasheet (document reference cycl_c5v1, also known as the Cyclone Device Handbook) is available from Intel's website. The datasheet covers electrical characteristics, timing models, package outlines, and configuration schematics for every Cyclone device including the EP1C4F400C6.
Where do I find the EP1C4F400C6 pinout?
The EP1C4F400C6 pinout is documented in the Cyclone Device Handbook, in the "Package Information" and "Pin Information" chapters. The 400-ball FineLine BGA uses a 1.0 mm ball pitch with eight user-I/O banks; each bank has dedicated VCCIO pins and reference-voltage inputs that must be planned in the PCB stackup.
Is the EP1C4F400C6 still in production?
No. As of 2026-09-06, the EP1C4F400C6 is on Intel's last-time-buy (LTB) list and is no longer recommended for new designs. Existing customers with active orders may still receive parts during the LTB window, but new production orders are not accepted. Migrate to a Cyclone IV EP4CE6 or Cyclone 10 LP equivalent for ongoing production.
What are the key specifications of EP1C4F400C6 that engineers should know?
The EP1C4F400C6 is a Cyclone-family FPGA with 4,000 logic elements (400 LABs), 301 user I/Os, 78 Kbits of embedded M4K RAM, two PLLs, a 1.5 V core supply, 130 nm CMOS process, and a 400-ball FineLine BGA package. It operates from 0°C to +85°C (commercial) at the -6 speed grade, supporting LVTTL/LVCMOS/SSTL/LVDS I/O standards.
What is a good cross-brand equivalent for the EP1C4F400C6?
There is no true cross-brand drop-in equivalent for the EP1C4F400C6 in the same 400-ball BGA package. The closest competitors in the same era and capacity class are the Xilinx Spartan-3 XC3S400 in a different BGA footprint (NOT pin-compatible), and the Lattice ECP2-series devices, also in non-compatible packages. Any cross-brand migration requires a PCB redesign.
What tools are required to program the EP1C4F400C6?
The EP1C4F400C6 is supported by the legacy Quartus II design software (versions up to 13.0sp1). Intel no longer ships active updates for the original Cyclone family, but archived Quartus II builds remain available. Programming is performed via JTAG or the Altera ByteBlaster / USB-Blaster download cable using SRAM Object Files (.sof) or Programmer Object Files (.pof).

Selection Guide

Choose the EP1C4F400C6 when your design fits in 4,000 logic elements, requires the -6 commercial speed grade for tightest timing closure, and operates in a 0°C to +85°C environment with no RoHS mandate. For new RoHS-compliant builds, prefer the EP1C4F400C8N — same die and package, lead-free finish, slightly slower speed grade. For industrial temperature deployments down to -40°C, select the EP1C4F400I7N. For long-term supply assurance beyond Intel's last-time-buy window, plan a migration to the Cyclone IV EP4CE6F17 or Cyclone 10 LP 10CL006 — note these are NOT drop-in compatible and require PCB redesign.

Key Differentiators

  • Lowest-cost 4,000-LE Cyclone variant with -6 speed grade (vs EP1C4F400C8N)
  • Commercial temperature range matches cost-driven designs (vs EP1C4F400I7N)
  • Leaded terminal finish for legacy manufacturing compatibility (vs EP1C4F400C6N)

Design Notes

The 400-ball FineLine BGA uses a 1.0 mm ball pitch, which mandates a 4-layer or 6-layer PCB stackup with microvia or sub-merged via technology for fan-out. Route all VCCINT (1.5V core) and VCCIO (per-bank I/O supply) rails with wide power planes and place 0.1 µF + 10 µF decoupling capacitors within 100 mil of every supply pin. Use a continuous GND plane on the layer immediately beneath the BGA to provide a low-impedance return path and to dissipate the 1.5W to 3W typical device power.

Estimated: at 100% logic utilization with 200 MHz internal clock, the EP1C4F400C6 dissipates approximately 1.5 W to 3 W. With a typical junction-to-ambient thermal resistance (θJA) of 12 °C/W for a 400-ball BGA on a 4-layer JEDEC test board, junction temperature rise above ambient is ~36 °C. For sustained high-activity designs, ensure at least 8 thermal vias in the BGA center pad to the internal GND plane to maintain junction temperature below 125 °C.

Do not mix LVTTL 3.3V and LVDS 2.5V signals in the same I/O bank without proper VCCIO planning — each bank shares a single VCCIO rail. Floating configuration pins (nCONFIG, nSTATUS, CONF_DONE) can cause undefined startup behavior; tie them through 10 kΩ pull-ups to VCCIO. For JTAG chains, ensure the JTAG pins are not repurposed as general I/O in the Quartus pin planner, or boundary-scan will fail. Finally, do not assume the original Cyclone bitstream format is compatible with Quartus Prime — use Quartus II 13.0sp1 or earlier for compilation.
