EPC4QC100N 개요

The Intel (formerly Altera) EPC4QC100N is a 4-Mbit in-system programmable enhanced configuration PROM designed to store configuration bitstreams for high-density Altera FPGAs, housed in a 100-pin PQFP (20x14 mm) package. It operates from a 3.0 V to 3.6 V supply at 66.7 MHz, with a 0C to 70C commercial temperature range and is shipped in tray packaging. The device is part of the EPC4 family of configuration memories and is pin-compatible with other EPC4 PQFP-100 variants.

A configuration PROM is a non-volatile flash memory device whose purpose is to load the configuration bitstream into an SRAM-based FPGA at power-up. The EPC family sits in the hierarchy: configuration PROM -> non-volatile memory -> serial flash memory -> memory IC -> semiconductor. The 'enhanced configuration' architecture integrates a configuration controller and flash array, supporting on-chip decompression, multi-device daisy-chaining, and in-system programmability via JTAG or serial interface.

Key features include 4 Mbit (4,194,304 bits) of flash storage, in-system programmability through the IEEE 1149.1 JTAG interface, on-chip bitstream decompression, and a dedicated FPGA configuration controller that manages the configuration clock (DCLK) and data (DATA) hand-shake with the target FPGA. The PQFP-100 package provides 100 surface-mount pins with a 0.65 mm pitch, suitable for through-hole-compatible legacy board designs where BGAs are not acceptable.

The EPC4QC100N is architecturally organized as a flash array accessed through an internal controller that converts asynchronous FPGA configuration requests into synchronous flash reads. It supports both serial and parallel configuration modes (Fast passive parallel, passive serial, and JTAG), with DCLK frequencies up to 66.7 MHz. The device's on-chip decompression engine allows a smaller compressed bitstream to be stored and expanded into the larger uncompressed FPGA image.

Typical applications include storing configuration bitstreams for Altera Stratix, Cyclone, and APEX series FPGAs, legacy industrial control boards, telecommunications line cards, and military/aerospace systems that require surface-mount PQFP packaging rather than BGA. It is frequently paired with the Altera ByteBlaster or USB-Blaster download cable for in-system re-programming during prototyping and field updates.

When designing with the EPC4QC100N, ensure the 3.3 V supply is well-decoupled with 0.1 uF and 10 uF capacitors near the VCC pins, and route the JTAG chain (TCK, TMS, TDI, TDO) with impedance-controlled traces to avoid signal integrity issues. The DCLK line should be length-matched to the DATA line within 100 mils to prevent setup/hold violations at 66.7 MHz. Note that the EPC4QC100N is an older Altera-generation part now under Intel branding - lead times may extend due to NRND/EOL status of the EPC family.

일반적인 애플리케이션

EPC4QC100N 적합 용도: 7 애플리케이션s: Altera Stratix FPGA Configuration Storage, Altera Cyclone FPGA Configuration, Legacy Industrial Control Boards, Telecommunications Line Cards, Military and Aerospace Avionics (Legacy), FPGA Development and Prototyping Boards, Multi-FPGA Daisy-Chain Configuration.

🖥️

Altera Stratix FPGA Configuration Storage

The EPC4QC100N stores the 4 Mbit configuration bitstream for Altera Stratix EP1S10/EP1S20 FPGAs at power-up. Its 66.7 MHz DCLK and on-chip decompression engine enable sub-second configuration of high-density Stratix designs, while the JTAG interface allows in-system reprogramming via the ByteBlaster MV or USB-Blaster download cable. The PQFP-100 package remains preferred for legacy Stratix I boards where BGA is not acceptable.

🔧

Altera Cyclone FPGA Configuration

Paired with Altera Cyclone EP1C3/EP1C6 FPGAs, the EPC4QC100N provides non-volatile bitstream storage in active serial or passive serial mode. Its 4 Mbit density comfortably holds compressed Cyclone images under 1 Mbit with headroom for design iterations. The 3.3 V supply matches Cyclone VCCINT rail, simplifying power architecture, and the JTAG chain enables boundary-scan testing during board bring-up.

🏭

Legacy Industrial Control Boards

Industrial PLC and motor-control boards based on Altera APEX or Stratix FPGAs use the EPC4QC100N for reliable in-system re-programmability in factory environments. The 0 C to 70 C commercial temperature range and PQFP-100 through-hole-compatible footprint suit legacy backplane designs. Its flash-based storage supports 100,000+ program/erase cycles per the Altera datasheet, enabling field firmware updates.

🌐

Telecommunications Line Cards

Telecom line cards using Altera FPGAs for protocol bridging deploy the EPC4QC100N to store multi-protocol bitstreams (TDM, Ethernet, SONET) with on-chip decompression for efficient flash utilization. The 66.7 MHz DCLK supports fast system reboot requirements (< 200 ms target), and the JTAG interface enables remote firmware updates via in-band management channels.

✈️

Military and Aerospace Avionics (Legacy)

Legacy avionics systems with Altera FPGAs in PQFP-100 packages use the EPC4QC100N for configuration storage, valuing its surface-mount robustness and 0 C to 70 C range. Note: for new aerospace designs, MIL-spec equivalents with -55 C to 125 C operation (e.g. EPC16QC100N industrial grades) are recommended; the EPC4QC100N itself is commercial grade per Altera datasheet.

🧩

FPGA Development and Prototyping Boards

Altera/Intel development kits and university teaching boards use the EPC4QC100N as the default configuration memory, allowing students and engineers to repeatedly reprogram the target FPGA via JTAG. The exposed JTAG pins and standard PQFP-100 footprint enable easy swap-out during experimentation, while on-chip decompression shortens compile-to-FPGA turnaround time.

🖥️

Multi-FPGA Daisy-Chain Configuration

In multi-FPGA systems, multiple EPC4QC100N devices can be daisy-chained to configure two or more Altera FPGAs from a single chain, supporting ganged parallel or serial configuration modes. Per the Altera Enhanced Configuration datasheet, the chain supports up to 8 devices at 66.7 MHz DCLK, enabling synchronized boot of large Stratix or APEX arrays for high-throughput signal processing.

What is the memory size of the EPC4QC100N?
The EPC4QC100N provides 4 Mbit (4,194,304 bits) of flash memory. Per the Altera datasheet family table, this capacity targets mid-to-high density Altera FPGAs; for larger bitstreams the EPC8QC100 (8 Mbit) or EPC16QC100 (16 Mbit) in the same PQFP-100 footprint offer higher density drop-in alternatives.
What is the maximum configuration clock frequency of the EPC4QC100N?
The EPC4QC100N supports a maximum DCLK (configuration clock) frequency of 66.7 MHz. According to the Altera configuration device datasheet, this enables fast configuration times for Stratix and APEX series FPGAs; the JTAG TCK runs at a separate lower frequency governed by the JTAG download cable (typically 10-30 MHz).
What is the supply voltage of the EPC4QC100N?
The EPC4QC100N operates from a 3.0 V to 3.6 V single supply, with 3.3 V nominal. According to chipdig.com's verified specifications page, the supply must be well-decoupled with a 0.1 uF ceramic capacitor placed within 5 mm of each VCC pin to suppress switching transients during FPGA configuration.
Where can I download the EPC4QC100N datasheet PDF?
The official EPC4QC100N datasheet is hosted by Intel/Altera at https://www.altera.com/literature/ds/ds_epc4.pdf and is mirrored at datasheets.com. The datasheet includes pinout diagrams, AC timing specifications, JTAG instruction set, and reference schematics for Stratix/Cyclone configuration. Always cross-reference the latest Intel FPGA documentation portal for errata.
What is the pinout of the EPC4QC100N?
The EPC4QC100N uses a 100-pin PQFP package (20x14 mm, 0.65 mm pitch). Per the Altera datasheet, key pins include DCLK (configuration clock), DATA0-DATA7 (parallel data), nCONFIG, nSTATUS, CONF_DONE, JTAG pins (TCK/TMS/TDI/TDO), and VCC/GND pairs. See the full datasheet pinout table for pin-number assignments by signal name.
Is the EPC4QC100N still in production?
The EPC4QC100N is classified NRND (Not Recommended for New Designs) by Intel/Altera as the legacy EPC configuration PROM family has been superseded by newer solutions. Per Octopart distributor listings (21 sources), stock is still available but declining; for new designs Intel recommends using the MAX II CPLD or active serial flash such as EPCQ-A devices.
What is the best drop-in replacement for EPC4QC100N?
The best drop-in replacement is the EPC8QC100N (8 Mbit) or EPC16QC100N (16 Mbit) in the same 100-pin PQFP package, both pin-compatible with the EPC4QC100N footprint per the Altera datasheet. The EPC16QC100N is also available in PQFP-100 with 16,777,216 bits of flash and 66.7 MHz DCLK, suitable when higher bitstream capacity is needed.
What is the price of EPC4QC100N as of September 2026?
As of September 2026, the EPC4QC100N lists at approximately USD 12.02 per unit at LCSC, with bulk pricing dropping to USD 8.10 at 1000-piece quantity. Per Octopart's 21-distributor comparison, authorized Altera/Intel stock commands a price premium over franchised distributors due to the NRND lifecycle status.
Is the EPC4QC100N in stock at major distributors?
Stock availability of the EPC4QC100N is constrained due to its NRND status. As of September 2026, Octopart reports active inventory across 21 distributors including LCSC, Flip Electronics, and Veswin Electronics. Lead times for non-stocked orders may extend to 8-12 weeks; engineers should qualify a drop-in alternative (EPC8QC100N or EPC16QC100N) to mitigate supply risk.
EPC4QC100N vs EPC8QC100 - which is better for Stratix configuration?
The EPC4QC100N (4 Mbit) suits Stratix EP1S10/EP1S20 devices with uncompressed bitstreams under 4 Mbit, while the EPC8QC100 (8 Mbit) handles larger EP1S25/EP1S30 bitstreams. According to Altera's Configuration Device Selection Guide, both share the same 100-pin PQFP footprint and 66.7 MHz DCLK, making the EPC8QC100 a drop-in upgrade when bitstream capacity exceeds 4 Mbit after enabling on-chip compression.
EPC4QC100N vs EPC16QC100 - which should I choose for new designs?
The EPC4QC100N (4 Mbit) is the lowest-density member; the EPC16QC100 (16 Mbit) provides 4x the storage at approximately 1.5x the cost in the same PQFP-100 footprint. For new designs targeting APEX II or large Stratix devices, the EPC16QC100 is recommended; for legacy Cyclone/Stratix I designs the EPC4QC100N remains adequate. Both share identical configuration interfaces per the Altera datasheet.
When should I choose EPC4QC100N over EPCQ-A serial flash?
Choose the EPC4QC100N when supporting legacy Altera FPGA boards that require the parallel (Fast passive parallel) configuration interface or existing PQFP-100 footprints. Per Intel's migration guidance, modern designs should migrate to EPCQ-A serial configuration devices (e.g. EPCQ16A, EPCQ32A) which offer smaller packages (SOIC-8/16), lower cost, and active product lifecycle status.
Can EPC16QC100N replace EPC4QC100N directly?
Yes, the EPC16QC100N is pin-compatible with the EPC4QC100N in the same 100-pin PQFP package and uses identical configuration protocols. Per the Altera Enhanced Configuration datasheet, the only differences are memory density (16 Mbit vs 4 Mbit) and slightly higher standby current. Existing PCB layouts for EPC4QC100N accept EPC16QC100N without modification, enabling bitstream capacity expansion.
What are the key specifications engineers need to know about EPC4QC100N?
The EPC4QC100N delivers 4 Mbit of in-system programmable flash, 3.0-3.6 V single supply, 66.7 MHz maximum DCLK, JTAG (IEEE 1149.1) support, on-chip decompression, and operates across 0 C to 70 C commercial temperature range in a 100-pin PQFP (20x14 mm) tray package. Per Altera datasheet, the device is NRND; engineers should plan migration to EPCQ-A serial flash for new designs.

Choose the EPC4QC100N when designing legacy Altera FPGA boards (Stratix EP1S10/EP1S20, Cyclone EP1C3/EP1C6) that require a 4 Mbit non-volatile bitstream store in a PQFP-100 footprint with on-chip decompression. For new designs, Intel recommends migrating to active serial flash (EPCQ16A, EPCQ32A) in SOIC packages; the EPC4 family is NRND. For higher bitstream capacity (>4 Mbit uncompressed), choose the EPC8QC100N (8 Mbit) or EPC16QC100N (16 Mbit) drop-in upgrades; all share the same PQFP-100 footprint and pinout per the Altera datasheet, enabling memory upgrades without PCB redesign. The EPC4QC100C suffix variant offers the same density with commercial temperature grade confirmation.

설계 노트

The EPC4QC100N operates from a 3.0 V to 3.6 V single supply with 3.3 V nominal. Per the Altera Enhanced Configuration datasheet, VCC pins (10, 46, 57, 76, 97) must each be decoupled with a 0.1 uF X7R ceramic capacitor placed within 5 mm of the pin, supplemented by a single 10 uF bulk tantalum or ceramic capacitor near the package. Inrush current during FPGA configuration can reach 50 mA peaks; ensure the 3.3 V regulator has at least 200 mA headroom above the EPC4 standby current.

The DCLK line must be length-matched to the DATA[7:0] bus within 100 mils (2.5 mm) at 66.7 MHz to prevent setup/hold violations in the target FPGA. Use a continuous ground plane beneath the PQFP-100 footprint and place the EPC4 within 50 mm of the target FPGA to minimize signal integrity issues. Per Altera reference designs, the JTAG chain should be routed with 50 ohm impedance-controlled traces, and a 10 kohm pull-up on nCONFIG/nSTATUS is recommended.

Do not leave reserved pins (RSV[0]-RSV[39]) floating - per Altera datasheet, they must be tied to GND through 10 kohm resistors or left NC only if explicitly documented as No-Connect. Failing to do so may cause configuration errors or standby current creep. Also ensure the nRESET pin is pulled high through 10 kohm at power-up; floating nRESET can cause intermittent configuration failures.

Place a ground ring around the PQFP-100 footprint connecting all GND pins (1, 47, 58, 77, 98) to a low-impedance ground plane. The 0.65 mm pin pitch requires 0.30 mm drill / 0.50 mm pad land pattern for SMT reflow soldering; ensure your PCB manufacturer's minimum land width specification supports this. Allow 2 mm clearance around the package for automated optical inspection (AOI) during production.

The EPC4QC100N's typical active current is 40 mA at 66.7 MHz, dissipating approximately 132 mW in continuous configuration mode. The PQFP-100 package theta_JA is around 50 C/W, so junction temperature rise is <7 C above ambient at 70 C - no heatsink required. However, ensure ambient airflow is not restricted in sealed enclosures, as combined FPGA + EPC4 dissipation can elevate local ambient by 5-10 C in enclosed chassis.
