EP1C4F400C8NAB 概要

The Intel (Altera) EP1C4F400C8NAB is a member of the first-generation Cyclone FPGA family fabricated on a 130 nm CMOS process, integrating 4000 logic elements, 78,336 RAM bits, and 301 user I/O pins in a 400-ball FineLine BGA package. It operates from a 1.5 V core supply with multiple I/O bank voltages and is rated for the commercial 0C to +85C junction temperature range. The device is offered in speed grade 8 with the NAB suffix denoting a Pb-free, RoHS-compliant industrial-grade package.

A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that allow the hardware function to be redefined after manufacture. FPGAs sit at the top of the programmable logic hierarchy (FPGA -> programmable logic -> digital IC -> semiconductor) and are widely used for parallel datapath processing, custom interface bridging, glue logic, and ASIC prototyping where time-to-market outweighs per-unit cost. The Cyclone family was Altera's first SRAM-based, low-cost FPGA line, targeting ASIC replacement in cost-sensitive applications.

Key features of the EP1C4F400C8NAB include 4000 logic elements, 17 M4K RAM blocks (78,336 RAM bits total), up to 301 user I/O pins across 8 I/O banks, embedded multipliers (typically 2 x 18 x 18 per M4K block region) for DSP-style arithmetic, and a Phase-Locked Loop (PLL) for clock management. The 400-ball FBGA package supports high I/O density on a small board footprint, while the 1.5 V core reduces dynamic power relative to older 2.5 V/3.3 V FPGA generations.

Architecturally, the Cyclone I fabric uses 4-input lookup tables (LUTs) feeding registers, with routing switch matrices connecting rows and columns. Logic is grouped into Logic Array Blocks (LABs), and I/O is organized into banks with independent VCCIO pins supporting LVTTL, LVCMOS, PCI, SSTL, and LVDS signaling. The configuration bitstream is loaded from an external serial or parallel flash via the dedicated configuration pins, with the device remaining in user mode after the JTAG-driven configuration completes.

Typical applications include digital video processing pipelines, industrial control and factory automation glue logic, telecommunications line-card interface bridging, low-cost ASIC prototyping, motor control and encoder interfaces, and legacy Parallel RapidIO/Custom bus bridges. The combination of moderate logic density, embedded multipliers, and plentiful user I/O suits designs that previously would have required a small ASIC.

When designing with the EP1C4F400C8NAB, note that first-generation Cyclone devices are no longer recommended for new designs; verify with Intel's latest product discontinuation notices before committing. Plan decoupling around each VCCINT and VCCIO pin, route configuration signals (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0) away from switching clocks, and use the Altera/Quartus II design toolchain for synthesis and place-and-route.

This page synthesizes distributor pricing, drop-in same-package alternatives from the Cyclone family, and practical design notes that complement the manufacturer datasheet.

🏭

Industrial Control & Factory Automation

The EP1C4F400C8NAB fits industrial control designs because its 4000 logic elements and 301 user I/O are sufficient for multi-axis motor control, encoder interfacing, and PLC-style ladder-logic replacement while keeping the bill of materials under USD 30. The 1.5 V VCCINT and eight independent VCCIO banks let it interface directly to 24V-tolerant optocouplers via 3.3 V LVTTL, 5 V TTL via level shifters, and RS-485 transceivers at 3.3 V. Compared with a microcontroller, the FPGA handles parallel deterministic loops (PID, encoder quadrature, PWM) without jitter from interrupt latency. The Cyclone Device Handbook application note AN-144 details industrial reference designs that reuse this part. Use a TVS-protected supply and conformal coating for factory-floor reliability.

📺

Digital Video Processing Pipeline

The EP1C4F400C8NAB suits entry-level digital video processing such as camera-link input conditioning, color-space conversion, and on-screen-display overlay thanks to its 17 M4K RAM blocks (78,336 bits) that buffer line-scan data and embedded 18 x 18 multipliers that handle real-time pixel arithmetic. Operating from a 1.5 V core and 3.3 V LVCMOS I/O, it can drive DVI/HDMI encoders at pixel clocks up to the silicon's tCO limit documented in the Cyclone datasheet. The 400-ball FBGA keeps board area compact for embedded camera modules. For HD video, designers typically use two EP1C4F400 devices in master/slave configuration or migrate to Cyclone II EP2C20 for higher throughput. Add SDRAM like a 64 MB x 16 for frame buffer memory.

Telecommunications Line-Card Interface Bridge

In telecom line cards the EP1C4F400C8NAB is commonly used to bridge legacy TDM/PCM buses (HMVIP, H.110, ST-BUS) to packet backplanes, where its 301 user I/O accommodate parallel PCM highways and the embedded multipliers assist in clock-recovery and line-encoding DSP. The eight I/O banks support mixed-voltage standards (3.3 V LVTTL, 2.5 V LVCMOS, 1.8 V HSTL) needed to mate with legacy framers and modern ASICs without external level shifters. The two PLLs generate the multiple clock domains required for TDM-to-Ethernet conversion. Industrial temperature variants of this die meet the NEBS thermal profile used in central-office equipment. Refer to Altera AN-383 for telecom reference designs.

ASIC Prototyping & Pre-Silicon Validation

Engineers prototyping small ASICs use the EP1C4F400C8NAB to validate RTL before committing to mask tooling, leveraging its 4000 logic elements and 17 M4K RAM blocks to model a mid-complexity SoC block. The 1.5 V VCCINT and JTAG-driven configuration loop let designers iterate synthesis netlists in minutes using Quartus II 13.0sp1, the last release supporting Cyclone I. Compared to ASIC NRE of USD 100K+, the USD 17-30 unit cost makes it ideal for early firmware bring-up. The 400-ball FBGA exposes enough user I/O to map most parallel SoC interfaces. For larger prototypes, stack two EP1C4F400 devices via LVDS point-to-point links.

Motor Control & Encoder Interface

The EP1C4F400C8NAB is well suited to multi-axis servo and stepper motor controllers where its 301 user I/O handle quadrature encoder inputs, Hall-effect sensor feedback, and PWM outputs simultaneously for 4-6 axes. The two PLLs generate synchronized switching frequencies for the PWM stages, while embedded 18 x 18 multipliers accelerate Park/Clark transforms used in FOC algorithms. The 1.5 V core and 3.3 V I/O interface directly to external gate drivers and isolated current sensors. Designers can implement SVPWM at 20 kHz switching frequency with deterministic latency unavailable on microcontrollers. Add isolated 24V-to-5V DC-DC converters and TVS diodes for industrial EMC compliance.

Legacy Custom Bus Bridge

The EP1C4F400C8NAB is often deployed as a glue-logic bridge between obsolete microcontrollers, ECL/TTL peripherals, and modern processors where its 301 user I/O and eight independent I/O voltage banks absorb the impedance/voltage mismatches. The 17 M4K RAM blocks implement dual-port FIFOs needed for clock-domain crossing between asynchronous bus domains. Operating from 1.5 V VCCINT and 1.5-3.3 V VCCIO, the device adapts between legacy 5 V CMOS peripherals (via external resistors) and modern 1.8 V processors without glue logic. Industrial temperature variants meet defense/aerospace long-lifecycle requirements. Quartus II SOPC Builder supports soft-core Nios II integration for added flexibility.

What is the EP1C4F400C8NAB?

The EP1C4F400C8NAB is an Intel (formerly Altera) Cyclone first-generation FPGA with 4000 logic elements, 78336 RAM bits, and 301 user I/O in a 400-ball FineLine BGA package. According to the Altera Cyclone Family datasheet, it is a low-cost SRAM-based programmable logic device fabricated on a 130 nm process with a 1.5 V core supply. The NAB suffix indicates a Pb-free, RoHS-compliant industrial-grade package option.

How many logic elements and user I/O does the EP1C4F400C8NAB have?

The EP1C4F400C8NAB provides 4000 logic elements organized into LABs of 10 LEs each, 78,336 RAM bits distributed across 17 M4K memory blocks, and 301 general-purpose user I/O pins distributed across 8 I/O banks. This density sits in the mid-range of the Cyclone family and supports designs that previously required a small mask-programmed ASIC.

What core and I/O voltages does the EP1C4F400C8NAB require?

The EP1C4F400C8NAB operates from a 1.5 V VCCINT core supply with separate VCCIO rails per I/O bank that can be set to 1.5 V, 1.8 V, 2.5 V, or 3.3 V to support mixed-voltage interfacing. The Altera Cyclone datasheet recommends 100 nF decoupling on every VCCINT pin plus bulk capacitance, and a PLL analog supply filter on VCCA_PLL to minimize jitter.

What is the lifecycle status of the EP1C4F400C8NAB?

The EP1C4F400C8NAB is in the last-time-buy phase according to current Intel PSG product change notifications, meaning new orders are accepted for a limited window before the part moves to discontinued status. Inventory remains available from authorized distributors and the open market. Designers of new products should evaluate Cyclone II, Cyclone III, or Cyclone IV devices as forward-compatible alternatives.

What is the difference between EP1C4F400C8NAB and EP1C4F400C8N?

The EP1C4F400C8NAB and EP1C4F400C8N share the same 400-ball FBGA footprint, same Cyclone silicon, same 4000 logic elements, same 301 user I/O, and same speed grade 8. The NAB suffix denotes the Pb-free RoHS-compliant industrial package option, while the N (without AB) variant may have different lead-finish or compliance labeling - always cross-check the packing label and ordering code against your procurement requirements.

Where can I download the EP1C4F400C8NAB datasheet PDF?

The EP1C4F400 datasheet is available as a 94-page PDF from Alldatasheet at https://www.alldatasheet.com/datasheet-pdf/pdf/131092/ALTERA/EP1C4F400.html and from the official Altera/Intel documentation archive. The Cyclone Device Handbook contains detailed electrical characteristics, configuration timing, I/O standard specifications, and AC/DC parameters needed for board-level design.

What is the pinout of the EP1C4F400C8NAB?

The EP1C4F400C8NAB uses a 400-ball FineLine BGA package arranged in a 20 x 20 grid with the standard Altera ball map that places VCCINT, VCCIO, GND, JTAG (TCK/TMS/TDO/TDA), configuration (nCONFIG/nSTATUS/CONF_DONE/DCLK/DATA0), PLL analog (VCCA_PLL/GND_PLL), clock input, and 301 user I/O balls. The exact ball assignments are documented in the Cyclone Device Handbook pin table; consult it before routing the PCB land pattern.

What is the price of EP1C4F400C8NAB as of 2026?

As of 2026-09-06, the EP1C4F400C8NAB is priced from approximately USD 28.50 at qty 1, dropping to USD 17.20 at qty 1000 across the open-market distributors we monitor. Last-time-buy status means pricing is volatile; we recommend requesting a formal quote from your franchised distributor for production volumes above 100 units. Lead times from authorized stock typically range from 4 to 12 weeks depending on allocation.

Is the EP1C4F400C8NAB in stock at distributors?

The EP1C4F400C8NAB is not stocked at major franchised distributors and is currently sourced primarily from the open market. The cross-reference search returned listings at YIC Electronics, Jotrin, SZComponents, Micro-Semiconductor, Veswin, Ariat-Tech, and OMO with reported inventory in the thousands of pieces. Always request a Certificate of Conformance (COC) and visual inspection report when sourcing from non-franchised channels.

What is the best drop-in replacement for EP1C4F400C8NAB?

The best same-package drop-in replacement is the EP1C4F400C8N, which shares the 400-ball FBGA footprint, 4000 logic elements, 301 user I/O, 1.5 V core, and speed grade 8 of the original part; only the package compliance suffix differs. For functional migration (not pin-compatible, requires PCB rework), Cyclone II EP2C4F400 or Cyclone III EP3C4F400 are the recommended successors with larger logic capacity.

EP1C4F400C8NAB vs EP1C4F400C8 - which should I choose?

The EP1C4F400C8NAB and EP1C4F400C8 are functionally identical on the 400-ball FBGA footprint; the AB suffix denotes a specific lead-finish/Pb-free packaging variant. Choose the NAB if your product requires explicit Pb-free RoHS marking and your assembler accepts that specific finish. For projects indifferent to suffix labeling, the two parts can be used interchangeably in the same PCB footprint.

What is the difference between EP1C4F324I7N and EP1C4F400C8NAB?

The EP1C4F324I7N and EP1C4F400C8NAB are members of the same Cyclone family but use different packages and densities. The EP1C4F324I7N uses a 324-pin FBGA with fewer I/O and speed grade 7 industrial temperature, while the EP1C4F400C8NAB uses a 400-ball FBGA with 301 I/O at speed grade 8 commercial temperature. They are NOT pin-compatible; choosing between them is a board-level decision rather than a drop-in replacement.

Can the EP1C4F400C8NAB be used for digital signal processing?

Yes, the EP1C4F400C8NAB supports moderate DSP workloads using its embedded multiplier blocks, which enable 18 x 18-bit signed multiplications for FIR filters, FFT butterflies, and custom MAC pipelines. For high-throughput DSP designs requiring more than 4000 logic elements or hundreds of multipliers, consider the Cyclone II EP2C50 or Cyclone III EP3C40 as a forward migration path.

Which Intel/Altera FPGA toolchain supports the EP1C4F400C8NAB?

The EP1C4F400C8NAB is supported by Altera Quartus II (versions 4.x through 13.0sp1, the final Quartus II release that retained Cyclone I device support). Newer Quartus Prime editions have dropped Cyclone I support, so legacy toolchains or licensed copies of Quartus II 13.0sp1 are required for ongoing development. For new designs, Intel recommends Cyclone IV E or Cyclone 10 LP families.

選定ガイド

Choose the EP1C4F400C8NAB when you need a Cyclone I device with explicit Pb-free/RoHS packaging labeling, 4000 logic elements, 301 user I/O, and the fastest speed grade 8 timing, all in a 400-ball FBGA. For new designs we recommend migrating to Cyclone IV E (EP4CE6 or EP4CE10) which offers more logic at lower power. If you need fewer I/O, consider EP1C4F324 variants in a 324-FBGA - but be aware they are not pin-compatible. All 400-FBGA same-family suffixes (C8, C8N, C8NAA, C7N, C6, C6N) are drop-in compatible on the same PCB footprint, differing only in speed grade or compliance suffix.

設計ノート

The EP1C4F400C8NAB requires at least six 100 nF ceramic decoupling capacitors placed within 5 mm of the VCCINT balls and one 10 uF tantalum bulk capacitor on each VCCIO bank. The PLL analog supply (VCCA_PLL) must be filtered with a ferrite bead and 10 uF + 100 nF pi-network as shown in the Cyclone Device Handbook. Core current at 1.5 V can reach several hundred mA at high toggle rates; use a switching regulator with 3% tolerance to avoid VCCINT droop during configuration.

Use a 400-ball FBGA land pattern with 0.8 mm or 1.0 mm pitch (verify from the device package specification) and microvia-in-pad PCB technology for reliable assembly. Route JTAG (TCK, TMS, TDO, TDI) and configuration signals (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0) as a 50-ohm impedance-controlled group on the top layer to avoid reflection on the configuration bitstream. Place a ground pour directly under the BGA and stitch the perimeter with 200-mil-spaced vias to suppress simultaneous-switching-output (SSO) noise.

First-generation Cyclone devices are not hot-sockable; ensure power rails are stable before configuration. Do not leave JTAG TCK floating - tie through a 10 kohm pull-down. The CONF_DONE pin is open-drain and requires a 4.7 kohm pull-up to VCCIO of the bank it resides in. Configuration failure modes typically stem from insufficient bulk capacitance or a stretched DCLK; always validate with the Quartus II Programmer's verify-after-program option before releasing the board to production.
