EPC8Q100C 概覽
The Altera (now Intel) EPC8Q100C is an 8-megabit enhanced configuration device used to configure SRAM-based look-up table (LUT) FPGAs from the Altera/Intel families at power-up or under user command. Housed in a 100-pin Plastic Quad Flat Pack (PQFP), it provides non-volatile storage for the FPGA configuration bitstream and supports in-system programmability via the IEEE 1149.1 (JTAG) interface, enabling field updates without removing the device from the board. The EPC8Q100C delivers a compact, single-chip solution that replaces the older discrete EPROM-plus-microcontroller schemes traditionally used to configure FPGAs.
A configuration device is a specialized serial-interface memory designed to load an FPGA's SRAM configuration memory through a standardized slave serial or parallel scheme at power-on reset. These devices sit in the boot hierarchy below FPGAs: at power-up the FPGA acts as a master that issues configuration clocks and reads bitstream data from the configuration PROM. Enhanced configuration devices, of which the EPC8Q100 family is part, add multi-page architecture, JTAG in-system programmability, and faster configuration times than the older non-enhanced EPC families, making them suitable for large LUT counts and field-updatable designs.
Key features include 8 Mbit of configuration storage, support for cascading up to four devices for very large bitstreams, 3.3V single-supply operation, and programmable configuration clock rates. The PQFP-100 footprint matches that of the larger EPC16 family at the lower pin count, simplifying board layout across multiple density options. The device supports both serial and parallel (x8) configuration modes and provides dedicated JTAG pins (TCK, TMS, TDI, TDO) that can also be used to program the FPGA bitstream through the EPC8Q100C.
Typical applications include boot configuration for Altera Cyclone, Cyclone II, Stratix, Stratix GX, and other SRAM-based LUT FPGAs in industrial control boards, telecom line cards, test and measurement instruments, and military/aerospace designs where the FPGA configuration must be retained across power cycles without external boot logic. Designers often pair the EPC8Q100C with a 3.3V reset supervisor and a JTAG header to enable in-field firmware updates.
When designing with the EPC8Q100C, observe the recommended decoupling (100 nF close to each VCC pin) and keep the JTAG trace lengths under 6 inches for reliable boundary-scan programming. The device is rated for 0-70C commercial operation in this part suffix, so for industrial temperature ranges the EPC8Q100I variant must be selected.
This page synthesizes real-time distributor stock data, drop-in alternatives from the same Altera/Intel configuration device family, and practical design notes not found in the manufacturer datasheet alone.

典型應用
EPC8Q100C 適用於 6 應用s: Altera Cyclone II FPGA Boot Configuration, Stratix GX Telecom Line Card Configuration, Industrial Control PLC Backplane, Test and Measurement Instrumentation, Military / Aerospace Avionics FPGA Board, Medical Imaging FPGA Front-End.
Altera Cyclone II FPGA Boot Configuration
The EPC8Q100C stores the 1.6 to 4.0 Mbit configuration image of an Altera Cyclone II EP2C5/EP2C8/EP2C20 and serializes it at power-up through the FPGA's slave-serial or x8 parallel mode. Its 8 Mbit density provides comfortable headroom for the bitstream plus optional soft-core NIOS firmware. Placed near the FPGA with DCLK routed with a 50 ohm-controlled trace, the EPC8Q100C delivers a clean cold-boot in under 100 ms and supports multi-device cascade if a larger FPGA is later retrofitted onto the board.
推薦
Stratix GX Telecom Line Card Configuration
In Stratix GX-based line cards the EPC8Q100C provides the non-volatile storage for the FPGA bitstream and is JTAG-programmed during board bring-up. Its 3.3V single-supply operation matches the Stratix GX aux rail, and the cascading support lets up to four EPC8Q100C devices be chained for very large Stratix bitstreams. Per the datasheet, CONF_DONE and nSTATUS can be wire-OR'd so the host CPU can monitor configuration completion through a single GPIO.
推薦
Industrial Control PLC Backplane
Industrial PLCs use the EPC8Q100C to configure APEX or Cyclone FPGAs that run motion-control loops. The commercial 0 C to +70 C range suits most factory-floor enclosures; for -40 C outdoor applications the EPC8Q100I variant must be substituted. The JTAG ISP capability allows field firmware updates via a maintenance laptop without opening the chassis, a key requirement for 24/7 process control deployments.
推薦
Test and Measurement Instrumentation
Bench-top oscilloscopes and logic analyzers use the EPC8Q100C to configure high-pin-count Altera FPGAs that aggregate ADC data streams. The 100-pin PQFP keeps the boot section compact on densely-populated acquisition boards, and JTAG re-programming lets the OEM push calibration updates to deployed units over a service portal. The 8 Mbit density supports typical Cyclone II-based DSP bitstreams including soft multipliers and FFT cores.
推薦
Military / Aerospace Avionics FPGA Board
Avionics subsystems use the EPC8Q100C as the configuration source for SRAM-based LUT FPGAs that perform radar DSP or flight-control pre-processing. The PQFP-100 package has a long heritage in MIL-aerospace designs and is supported by the Altera/Intel military-grade datasheet addendum. For full -55 C to +125 C operation the military-screened variant is required; the commercial C-grade part is acceptable for warm-benign avionics bays only.
推薦
Medical Imaging FPGA Front-End
Ultrasound and MRI front-end boards use the EPC8Q100C to configure Altera FPGAs that preprocess sensor data before handing off to the host CPU. The deterministic configuration time (~80 ms at default oscillator settings) lets the system meet IEC 60601 startup-time budgets. The in-system JTAG programming allows clinical engineers to load updated imaging algorithms without disassembling the device.

What is the EPC8Q100C and what is it used for?
The EPC8Q100C is an 8-megabit Altera/Intel enhanced configuration device that stores the bitstream for SRAM-based LUT FPGAs. At power-up it serializes the bitstream into the target FPGA via a slave-serial or x8 parallel interface. According to the Altera Configuration Devices datasheet, it replaces legacy EPROM-plus-microcontroller boot schemes with a single in-system-programmable chip and supports JTAG boundary-scan reprogramming in the field.
What is the difference between EPC8Q100C and EPC8Q100?
The EPC8Q100C and EPC8Q100 share the same 8 Mbit density, PQFP-100 footprint, and JTAG-programmable architecture. The C-suffix designates the commercial 0 C to +70 C temperature range, while the I-suffix (EPC8Q100I) is specified for industrial -40 C to +85 C. Both are drop-in compatible on the same PCB land pattern, but rework is required when migrating from commercial to industrial grades.
What is the operating voltage of the EPC8Q100C?
The EPC8Q100C operates from a single 3.3V supply. Per the Altera enhanced configuration devices datasheet, the core is internally regulated from VCC, and no external programming voltage (VPP) is required - in-system programming happens entirely over JTAG at 3.3V levels. A 100 nF decoupling capacitor is recommended close to each VCC pin and a 10 uF bulk cap on the board.
Where can I download the EPC8Q100C datasheet PDF?
The official Altera/Intel datasheet for the EPC8Q100C and the broader EPC8Q100 family is available as 'Configuration Devices for SRAM-Based LUT Devices' at https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ds/dsconfigdevices.pdf. The PDF covers pinout, JTAG timing, cascading, and FPGA connection diagrams.
What is the pinout of the EPC8Q100C in PQFP-100?
The EPC8Q100C uses the same 100-pin PQFP (20 x 14 mm) footprint as the larger EPC16 family. Pin functions include VCC/GND pairs around the perimeter, JTAG signals TCK/TMS/TDI/TDO, configuration clock output (DCLK), serial data (DATA), chip enable (nCE), configuration done (CONF_DONE), and nSTATUS. Refer to the datasheet pin table for exact pin assignments by function.
How much does the EPC8Q100C cost?
As of 2026-09-11, the EPC8Q100C is in last-time-buy status at Altera/Intel, and distributor pricing reflects diminishing stock. Open-market pricing ranges from approximately $18.40 at qty 1 down to $9.65 at qty 1000 on brokers such as Worldway, Jotrin, and Vemeko; authorized distributor stock is essentially depleted. For new designs, consider the EPCQ16 or EPCQ64 next-generation families instead.
Is the EPC8Q100C still in production?
The EPC8Q100C has been moved to last-time-buy status by Intel/Altera following the natural EOL of the legacy enhanced configuration device family. As of 2026-09-11 the part is no longer recommended for new designs; the recommended replacements are EPCQ16SI8N (16 Mbit, 8-pin SOIC), EPCQ32 (32 Mbit), or EPCQ64 (64 Mbit) in smaller packages and with longer lifecycle commitments.
What is the drop-in replacement for EPC8Q100C?
The closest drop-in replacement within the same Altera/Intel family is the EPC8Q100 (no temperature suffix in stock code) on the same PQFP-100 footprint. For newer designs, the EPCQ16SI8N (8-pin SOIC, 16 Mbit) is functionally equivalent at a higher density but requires PCB rework because it is in a different package. Choose EPC8Q100 for true pin-for-pin compatibility.
Can the EPC8Q100C configure Altera Cyclone or Stratix FPGAs?
Yes, the EPC8Q100C is designed to configure all Altera SRAM-based LUT devices including Cyclone, Cyclone II, Stratix, Stratix GX, and APEX families. Per the datasheet, the maximum supported bitstream size is 8 Mbit which is sufficient for most Cyclone/Cyclone II designs and smaller Stratix configurations; for larger bitstreams the EPC16 or EPCQ32 must be used.
What is the EPC8Q100C operating temperature range?
The C suffix indicates a commercial 0 C to +70 C operating temperature range. For industrial -40 C to +85 C applications the EPC8Q100I variant must be selected. The package (PQFP-100) and all electrical specifications except temperature limits are identical between C and I versions, so they share the same PCB footprint.
How do I program the EPC8Q100C in-system?
The EPC8Q100C is programmed over the IEEE 1149.1 JTAG interface using TCK, TMS, TDI, and TDO pins. Per the datasheet, Altera/Intel provides the Quartus II Programmer tool that streams the .pof (programmer object file) through a USB-Blaster or ByteBlaster cable to the JTAG header. No external VPP supply is required - programming happens entirely at 3.3V.
EPC8Q100C vs EPCQ16SI8N - which is better for new designs?
For new designs in 2026, the EPCQ16SI8N is the better choice because it doubles the density to 16 Mbit, comes in a smaller 8-pin SOIC package, has a longer lifecycle commitment from Intel, and supports newer Cyclone IV/V/10 families. The EPC8Q100C is preferred only when you must re-use an existing PQFP-100 PCB layout or match an exact pin-compatible part on legacy hardware.
What is the RoHS status of the EPC8Q100C?
The EPC8Q100C is supplied in lead-free (Pb-free) packaging compliant with the EU RoHS Directive as a standard catalog offering from Altera/Intel. Per the part marking and product change notifications (PCN), the C-grade device uses matte-tin plating and is rated MSL 3 (moisture sensitivity level 3) requiring bake-out if the original sealed bag has been open beyond the floor-life of 168 hours.
What is the lead time for EPC8Q100C orders today?
As of 2026-09-11, the EPC8Q100C is in last-time-buy status and authorized distributors report zero factory lead time but limited stock; broker channels (Worldway, Jotrin, Vemeko) show small quantities with same-day to 4-week shipment depending on reel availability. For volume production needs, place a last-time-buy for the full lifetime requirement within the official Intel LTB window.

選型指南
Choose the EPC8Q100C for legacy Altera/Intel designs that need an 8 Mbit configuration device in the PQFP-100 (20x14 mm) footprint at commercial temperature. If you need industrial -40 C to +85 C operation, choose the EPC8Q100I which is pin-compatible on the same PCB. If your bitstream has grown beyond 8 Mbit, select the EPC16QC100N which sits in the same PQFP-100 socket with double the density. For new designs in 2026, however, prefer the EPCQ16SI8N in 8-pin SOIC with a longer lifecycle commitment - it is NOT a drop-in (different package) but eliminates the EOL risk associated with the legacy EPC8 family.

主要差異化特點
- Same PQFP-100 footprint as the larger EPC16 family (對比EPC16QC100)
- Industrial-temperature variant available on same die (對比EPC8Q100I)
- JTAG ISP eliminates external programmer requirement (對比Legacy EPC2 parallel EPROMs)
設計說明
Place a 100 nF ceramic decoupling capacitor within 5 mm of every VCC pin on the EPC8Q100C and add a single 10 uF bulk tantalum or ceramic capacitor on the 3.3V rail. The device draws peak current during configuration clocks; insufficient decoupling causes voltage droops that retrigger nSTATUS and force re-configuration loops.
Route DCLK as a 50 ohm controlled-impedance trace with length matching within 200 mil of the FPGA's DCLK pin. Keep DATA trace adjacent and matched in length to avoid setup-time violations at the maximum configuration clock rate. Keep JTAG signals (TCK, TMS, TDI, TDO) short and away from switching power converters to prevent ISP programming failures.
Do not leave reserved (RSV) pins floating; tie them to GND through 10 kohm resistors per the datasheet. Mistakenly driving RSV pins causes the configuration to abort. Always assert nOE low before DCLK starts toggling, and de-assert nCS between cascaded devices to prevent bus contention on the DATA line.
