EPC8Q100C Présentation
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.

Applications typiques
EPC8Q100C convient pour 6 applications: 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.
Recommandé
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.
Recommandé
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.
Recommandé
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.
Recommandé
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.
Recommandé
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.

Principaux différenciateurs
- Same PQFP-100 footprint as the larger EPC16 family (vs EPC16QC100)
- Industrial-temperature variant available on same die (vs EPC8Q100I)
- JTAG ISP eliminates external programmer requirement (vs Legacy EPC2 parallel EPROMs)
Notes de conception
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.
