EPC8QC100C Visão geral
A configuration PROM (also called a configuration device) is a non-volatile memory device that stores the FPGA's bitstream and loads it into the SRAM-based FPGA at power-up or upon reconfiguration. The Enhanced Configuration device family represents the third generation of Altera configuration PROMs, succeeding the older EPC1 and EPC2 families, and is specifically targeted at high-density FPGA configuration. The EPC8QC100C sits in the family hierarchy as follows: configuration PROM -> non-volatile memory -> memory IC -> integrated circuit -> semiconductor.
Key features include 8 Mbits of flash memory, support for 3.3V or 5V operation depending on variant, a simple four-pin interface to the FPGA (nCONFIG, nSTATUS, CONF_DONE, DCLK/DATA), and compatibility with Altera's Quartus programming tools. The 100-pin PQFP package provides mechanical robustness for industrial and production environments while maintaining a manageable footprint for board-level integration.
The EPC8QC100C's architecture uses a flash-based controller that supports fast programming and reprogramming via JTAG or the Altera ByteBlaster/USB-Blaster cable. The device supports both serial and parallel configuration modes, enabling design flexibility for single-FPGA or multi-FPGA configuration chains.
Typical applications include configuring Altera FPGAs such as the APEX, Mercury, Stratix, Cyclone, and ACEX families in telecom, industrial, military, and networking equipment. The 8 Mbit density is suitable for mid-to-large density FPGAs and supports multiple configuration images for remote field updates.
When designing with this device, ensure proper connection of the configuration control signals (nCONFIG, nSTATUS, CONF_DONE) between the EPC8QC100C and the target FPGA. Decoupling capacitors should be placed close to the VCC pins, and the DCLK trace should be length-matched to the FPGA clock input to avoid setup/hold violations during configuration.

Aplicações típicas
EPC8QC100C é adequado para 6 aplicaçãos: Single FPGA Configuration (Stratix / Cyclone), Multi-FPGA Concurrent Configuration, Industrial Control Systems, Telecom Line Cards, Military and Aerospace Avionics, Test and Measurement Equipment.
Single FPGA Configuration (Stratix / Cyclone)
The EPC8QC100C is purpose-built for loading bitstreams into single Altera FPGAs such as Stratix, Cyclone, and APEX devices via Passive Serial mode. The 8 Mbit density comfortably fits mid-range FPGA bitstreams including Stratix EP1S10 through EP1S25 and Cyclone EP1C12 through EP1C20 when bitstream compression is enabled in Quartus. Placed adjacent to the FPGA on the PCB with four critical signals (nCONFIG, nSTATUS, CONF_DONE, DCLK), the device powers up, reads its internal flash, and serially clocks the configuration data into the FPGA within milliseconds. The 100-pin PQFP provides ample I/O for addressing, JTAG, and parallel mode even in the simplest single-FPGA application, leaving room for future density scaling.
Recomendado
Multi-FPGA Concurrent Configuration
The EPC8QC100C supports concurrent configuration of up to eight PS device chains, enabling parallel loading of multiple FPGAs on the same board to reduce system startup time. Each chain receives its own data stream from the EPC8QC100C, allowing an 8-FPGA system to configure in roughly the time of a single FPGA load. This is critical in telecom and networking line cards where rapid reboot after power-cycle events is mandatory for service-level agreements. The 8 Mbit density is sufficient for smaller FPGAs in the chain while larger members use their own EPC16 devices, all sharing the same 100-pin PQFP footprint and software flow.
Recomendado
Industrial Control Systems
Industrial PLCs, motor controllers, and SCADA systems frequently use mid-density Altera FPGAs paired with the EPC8QC100C to enable field updates and reliable cold-start behavior. The EPC8QC100C stores the FPGA bitstream in non-volatile flash, allowing power-cycle recovery without host processor intervention. Industrial temperature variants of the device support -40C to +85C operation, suitable for factory floor and outdoor cabinet installations. The PQFP package withstands vibration typical of industrial enclosures better than BGA alternatives, and the JTAG interface permits on-site reprogramming for bug fixes without removing the board.
Recomendado
Telecom Line Cards
Telecom line cards using Altera Stratix or APEX FPGAs rely on the EPC8QC100C to ensure rapid, deterministic configuration at every power-up event including brief brownouts. The PROMs low standby current and predictable power-on reset behavior meet telecom reliability requirements, while the concurrent configuration mode allows multiple FPGAs (fabric, framer, packet processor) to boot in parallel. The 100-pin PQFP package is preferred in telecom because it supports rework with conventional hot-air stations, lowering field-repair cost. Multiple bitstream images can be stored if the system uses remote firmware update via JTAG.
Recomendado
Military and Aerospace Avionics
Defense and avionics systems using Altera FPGAs (particularly radiation-tolerant or military-screened variants) historically pair with the EPC8QC100C for bitstream storage. While newer programs use FPGAs with internal flash or radiation-hardened PROMs, legacy platforms continue to use the EPC8QC100C for its reliability and the maturity of the Altera configuration scheme. The PQFP package is preferred for avionics because it allows visual inspection and X-ray inspection of solder joints, important for flight-qualified assemblies. The EPC8QC100C also supports multiple configuration images, enabling fail-safe fallback bitstreams for mission-critical applications.
Recomendado
Test and Measurement Equipment
Test and measurement instruments such as oscilloscopes, logic analyzers, and protocol testers leverage Altera FPGAs paired with EPC8QC100C configuration PROMs to enable flexible factory calibration and field firmware upgrades. The 8 Mbit density accommodates bitstreams for mid-density FPGAs used in signal processing paths, while the JTAG interface allows manufacturers to load test patterns and calibration coefficients during ATE. Concurrent configuration mode is used when an instrument contains multiple FPGAs handling acquisition, triggering, and display subsystems, enabling all subsystems to come online simultaneously for fast test-start sequences.

Notas de projeto
Route DCLK, DATA, nCONFIG, nSTATUS, and CONF_DONE as a matched-length group between the EPC8QC100C and the target FPGA. Keep trace lengths under 50 mm where possible to avoid setup/hold violations at high DCLK rates. Place a 0.1 uF ceramic decoupling capacitor within 5 mm of each VCC pin and a 10 uF bulk capacitor at the device supply entry point. Source: Altera Enhanced Configuration Devices datasheet application notes.
Estimated: JTAG chain routing should keep TDI-TDO daisy-chain stubs under 50 mm to prevent signal reflections. If programming multiple devices in a JTAG chain, place the EPC8QC100C closest to the JTAG header so the FPGA's JTAG pins remain accessible after the PROM. The JTAG signals (TDI, TMS, TCK, TDO) require 10 kohm pull-ups to VCC if not driven during normal operation.
Do not confuse the EPC8QC100C with the EPCQ128A, which uses a 16-pin SOIC package and a different configuration protocol (active serial vs passive serial). The EPC8QC100C uses the older Altera PS scheme and is only compatible with FPGAs that support PS configuration (Cyclone, Stratix, APEX, ACEX). For modern MAX 10 or Cyclone 10 GX designs, use the EPCQ-A family instead.
When using parallel configuration mode to minimize load time, ensure the address and data buses are not heavily loaded by other devices on the board. Source termination resistors (33 ohm) on the DATA outputs of the EPC8QC100C are recommended if the FPGA is more than 100 mm away or if there are intermediate connectors.
