EPC4QC100N Présentation
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.

Applications typiques
EPC4QC100N convient pour 7 applications: 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.
Recommandé
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.
Recommandé
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.
Recommandé
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.
Recommandé
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.
Recommandé
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.
Recommandé
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.

Notes de conception
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.
