EPC8QC100N Übersicht
A configuration memory IC is a specialized non-volatile storage device that holds the FPGA's bitstream and serially delivers it to the FPGA at power-up through a dedicated configuration interface (such as Altera's FPP, PS, or AS modes). Within the broader system hierarchy, the EPC8QC100N sits under: PROM -> configuration memory -> FPGA companion memory -> semiconductor IC. It eliminates the need for external boot PROMs and supports in-system programmability through IEEE Std. 1532-compliant JTAG and Jam STAPL flows.
Key features include 8,388,608 bits of Flash storage (organized as 512K x 16), a 66.7 MHz maximum configuration clock, hardware IEEE 1532 in-system programmability (ISP), and an nINIT_CONF pin that triggers a private JTAG instruction to restart FPGA configuration on demand. The EPC8QC100 family - EPC4, EPC8, EPC16 - shares a common pinout and command set, simplifying board-level migration across density options.
Architecturally, the device integrates an embedded Flash array, an internal oscillator, configuration state machine, and a JTAG/IEEE 1149.1 boundary-scan controller. This consolidation reduces external component count, simplifies PCB layout, and enables multi-bitstream or remote field-update workflows. The single 3.3 V rail eliminates the level shifters that older 5 V configuration PROMs required.
Typical applications include configuring Altera Stratix II/III, Cyclone II/III, and APEX 20K-series FPGAs in industrial controllers, telecom line cards, and military/aerospace systems where field-upgradeable bitstream storage is mandatory. Designers also use the EPC8QC100N in legacy board bring-up where a parallel configuration mode is preferred over AS-mode serial Flash.
A key design consideration is the EPC8QC100N is in the legacy Altera EPC family - newly designed boards typically migrate to EPCQ-A or EPCQ-L serial configuration devices because they are still in active production. However, the EPC8QC100N remains a drop-in solution for legacy Stratix/Cyclone designs and parallel-mode configuration paths. Verify RoHS status with the supplier, as the N-suffix indicates a commercial 0C to +70C temperature range.

Typische Anwendungen
EPC8QC100N ist geeignet für 6 Anwendungs: Altera Stratix FPGA Configuration, Altera Cyclone FPGA Configuration, APEX 20K Series FPGA Boot Memory, Telecom Line Card Bring-Up, Military / Aerospace Avionics, Industrial Controller Multi-FPGA Boards.
Altera Stratix FPGA Configuration
The EPC8QC100N delivers the 8 Mbit Stratix and Stratix-II bitstream at up to 66.7 MHz in fast parallel configuration (FPP) mode, replacing legacy 5 V EPROM PROMs. Its 3.3 V single supply matches Stratix VCCIO without level shifters, and IEEE 1532 JTAG allows field firmware updates without board removal. The nINIT_CONF pin can restart FPGA configuration on demand, simplifying multi-FPGA board bring-up. The PQFP-100 package provides robust mechanical reliability for industrial telecom and military/aerospace applications.
Empfohlen
Altera Cyclone FPGA Configuration
The EPC8QC100N fits Cyclone, Cyclone II, and Cyclone III bitstreams that compress to under 8 Mbit. Its 66.7 MHz maximum configuration clock completes Cyclone-II configuration in under 100 ms, well below typical power-supply ramp windows. Single 3.3 V operation removes the need for 5 V rails on cost-sensitive consumer and industrial boards, and JTAG/1532 ISP enables remote firmware updates over Ethernet-connected MCUs. The PQFP-100 footprint is shared with EPC4QC100N, supporting cost-down on smaller bitstreams.
Empfohlen
APEX 20K Series FPGA Boot Memory
APEX 20K and APEX II FPGAs use parallel configuration with the EPC8QC100N providing the multi-Mbit bitstream. The nINIT_CONF pin enables software-controlled reconfiguration, useful for APEX systems that switch between two personalities at runtime. Industrial temperature grades (via EPC8QI100N drop-in alternative) extend operation to -40 C to +85 C for factory-floor APEX designs. The IEEE 1149.1 JTAG interface is supported by legacy Altera Quartus-II programmers for in-system programming during board test.
Empfohlen
Telecom Line Card Bring-Up
Telecom line cards using multiple Altera FPGAs benefit from the EPC8QC100N's parallel configuration mode and the nINIT_CONF pin for synchronized multi-FPGA boot sequences. Each FPGA on the line card can be daisy-chained or fed from its own EPC8 device, and the 66.7 MHz clock keeps total boot time under 500 ms even for four-FPGA configurations. Field-serviceable bitstream updates via JTAG eliminate the need to remove line cards for firmware upgrades, a critical MTBF improvement for carrier-grade telecom infrastructure.
Empfohlen
Military / Aerospace Avionics
Avionics systems requiring non-volatile, radiation-tolerant FPGA configuration rely on the EPC8QC100N's mature Flash-based design and extended-temperature drop-in variants. The PQFP-100 package withstands vibration and thermal cycling better than BGAs in some legacy avionics enclosures. IEEE 1532 in-system programmability allows depot-level firmware updates without desoldering, reducing mean-time-to-repair. The single 3.3 V supply simplifies power-tree design in 28 V avionics buses when paired with hold-up converters.
Empfohlen
Industrial Controller Multi-FPGA Boards
PLC and motion-controller boards pair EPC8QC100N devices with multiple Altera FPGAs to distribute real-time processing across parallel logic. The 66.7 MHz configuration clock brings all FPGAs online within deterministic time windows, essential for safety-rated industrial controllers that must reach a known state within a defined power-on interval. Field firmware updates via JTAG/1532 ISP allow factory operators to roll out new PLC logic without halting production lines, significantly reducing total cost of ownership.

Wichtigste Unterscheidungsmerkmale
- Drop-in density options within the EPC family (vs. EPC4QC100N and EPC16QC100N)
- Industrial-temperature drop-in available (vs. EPC8QI100N)
- nINIT_CONF pin for on-demand reconfiguration (vs. EPC8QC100 (no N-suffix variant))
Designhinweise
The EPC8QC100N operates from a single 3.3 V supply on VCC pins. Decouple each VCC pin with a 100 nF X7R ceramic capacitor placed within 5 mm of the package. Add a bulk 10 uF tantalum or polymer capacitor near the device. The internal Flash read during configuration can draw up to 50 mA peak; ensure the upstream regulator has at least 200 mA of headroom above quiescent current. For Stratix-II systems where VCCIO is 1.8 V or 2.5 V, add series resistors (33 ohm) on DCLK and DATA[15:0] lines to limit voltage excursions and reduce signal-integrity issues.
The PQFP-100 package has 0.65 mm lead pitch and requires careful soldering with no-clean SAC305 paste and a profiled reflow ramp no faster than 2 C/s. Keep all 100 traces on inner PCB layers and route length-matched within 25 mm on the 16-bit DATA bus to meet the 66.7 MHz timing budget. Place the EPC8QC100N within 50 mm of the FPGA's DATA, DCLK, nCONFIG, nSTATUS, and CONF_DONE pins to keep configuration-clock edges clean. Add a 10 kohm pull-up on nCONFIG and nSTATUS to VCCIO of the FPGA.
Do not attempt to use the EPC8QC100N with FLEX 10K or other 5 V-only Altera FPGAs - the EPC device is a 3.3 V part and will not drive 5 V inputs reliably. When migrating from EPC4QC100N to EPC8QC100N, verify that the Quartus .sof-to-.hex conversion correctly uses the lower-density option for backward compatibility - EPC8 bitstreams can be downgraded to EPC4 format but the reverse is not possible. The nINIT_CONF pin is active-low; floating it leaves the JTAG private instruction disabled. Always tie unused DATA[7:0] to GND through 10 kohm resistors on 16-bit-configured boards running in 8-bit mode.
Compliance-Informationen
RoHS, REACH, lead-free, and halogen-free status not specified in the verified web data; verify with supplier before use in RoHS-compliant designs. The EPC8 family is not AEC-Q100 qualified - choose EPC8QI100N for industrial-grade applications.
