EPC4QQC100C 개요
A configuration PROM is a non-volatile flash device whose sole purpose is to load an FPGA's SRAM configuration memory at power-up via the FPGA's serial or parallel configuration port. The EPC4 series sits in the hierarchy: Configuration PROM -> non-volatile memory -> configuration storage -> FPGA support silicon -> programmable logic ecosystem. Unlike boot flash used with microcontrollers, configuration PROMs are tightly coupled to Altera/Intel proprietary configuration protocols and JTAG-based in-system programming (ISP) flows.
Key features include 4 Mbit flash density, JTAG-based in-system programmability via IEEE 1149.1 boundary-scan, cascading support for FPGAs requiring >4 Mbit, and compatibility with FPP (Fast Passive Parallel), PS (Passive Serial), and AS (Active Serial) configuration schemes. The 100-PQFP (20x14 mm) package provides robust through-hole-style surface-mount handling suitable for industrial and prototyping builds, while the -C speed grade and Q-temperature grade indicate commercial-grade timing and operating temperature.
Technically, the EPC4QQC100C integrates a configuration controller and flash memory on one die, with internal voltage regulation, JTAG controller, and Altera-specific configuration state machines. Designers benefit from simplified BOM (one chip vs separate flash + controller) and proven FPGA interoperability verified across generations of Quartus Programmer releases.
Typical applications include FPGA boot configuration for industrial controllers, telecom line cards, military/aerospace prototypes, test and measurement chassis, and any design using mid-to-large Altera/Intel FPGAs that require non-volatile configuration storage. It is also used in legacy board revisions and field-upgradeable systems where ISP via JTAG is required.
When designing with this device, note that newer Intel/Altera FPGAs (Cyclone 10, Arria 10, Stratix 10, Agilex) typically use EPCQ-A or second-generation configuration quad-mode flash in 16-pin SOIC packages; the EPC4QQC100C remains valuable for legacy Stratix/Stratix II/Cyclone II/III/IV designs or as a compatible replacement for older Altera EPROM-style configuration chains. Verify pinout against the target FPGA's configuration controller datasheet before substitution.
This page synthesizes verified distributor stock, same-family drop-in alternatives from the EPC4 family, and practical design notes not found in the manufacturer datasheet alone, accelerating engineer sourcing decisions for legacy Altera configuration designs.

Legacy Cyclone/Stratix FPGA Configuration
The EPC4QQC100C stores 4 Mbit of configuration data for legacy Altera/Intel FPGAs such as Cyclone, Cyclone II/III/IV, Stratix, Stratix II, and APEX families, which require non-volatile boot memory at power-up. Its 3.0-3.6V supply and multi-volt I/O (1.8V/2.5V/3.3V) align directly with these FPGA configuration-port voltage rails, eliminating level shifters. JTAG IEEE 1149.1 ISP allows in-system bitstream updates during prototype bring-up without removing the device. Compared to using a generic SPI flash with a soft controller, the EPC4QQC100C offloads the configuration state machine to dedicated hardware, simplifying firmware and shortening power-to-ready time. Verified distributor stock as of 2026-09-11 makes it suitable for sustaining legacy production lines.

The 4 Mbit density supports typical Cyclone-class acquisition and processing bitstreams. JTAG ISP accelerates lab bring-up and calibration routines - engineers can iterate firmware via JTAG rather than swapping PROMs. The 100-PQFP footprint eases manual rework and clip-on probing during characterization. Pricing as of 2026-09-11 is acceptable for low-volume T&M product runs.
추천
Military and Aerospace Legacy Systems
Legacy military and aerospace platforms persist on Altera/Intel FPGAs that boot from EPC4-class configuration PROMs due to long qualification cycles and certification inheritance. The EPC4QQC100C maintains this compatibility for retrofits, spare-part provisioning, and engineering refresh programs. JTAG ISP enables controlled firmware updates with full traceability required in DO-254 and MIL-STD-810 programs. The 100-PQFP package's heritage in MIL-spec designs simplifies procurement documentation. When sourcing for defense applications, verify lot trace and authenticity with franchised distributors as of 2026-09-11.

설계 노트
Power the EPC4QQC100C from a regulated 3.3V rail with bulk decoupling of at least 10 uF tantalum or ceramic plus a 0.1 uF ceramic high-frequency bypass placed within 5 mm of each VCC pin. The multi-volt VCCIO pin should be tied to the FPGA's configuration-port supply (typically 2.5V or 3.3V); do not leave VCCIO floating, or the multi-volt output buffers may enter indeterminate states and corrupt DCLK/DATA timing.
Do not confuse the EPC4 family with EPCQ-A / second-generation EPCQ configuration quad-mode flash: those use 16-pin SOIC packages and AS x4 protocols targeting Cyclone 10/Arria 10/Stratix 10/Agilex, and are NOT pin-compatible with the EPC4QQC100C. Verify FPGA configuration-controller protocol before substitution; cross-family substitution requires PCB rework.
Route DCLK and DATA[15:0] signals as a matched bus with impedance-controlled traces (50 ohm typical) and keep trace lengths matched within 1 cm to preserve setup/hold timing at high DCLK frequencies. Place the EPC4QQC100C within 5 cm of the FPGA's configuration port to minimize transmission-line effects; longer distances risk reflection-induced configuration failures. Maintain a ground reference plane under the entire configuration bus.
The 100-PQFP (20x14 mm) package provides moderate thermal dissipation. Estimated: at typical JTAG-ISP-active and idle modes, the EPC4QQC100C draws ~25 mA from VCC (3.3V), dissipating ~83 mW - well within package limits and not requiring additional heatsinking. For enclosed chassis with poor airflow, derate ambient temperature by 10 C from the manufacturer maximum.
