EPC16QI100 概要
An FPGA configuration PROM (Programmable Read-Only Memory) is a non-volatile memory that stores the FPGA bitstream and presents it to the FPGA at power-up through a serial configuration interface. EPC-class enhanced configuration devices are positioned in the system hierarchy as Memory ICs > Configuration PROMs > FPGA support devices, with flash memory technology providing the underlying storage layer. By offloading configuration storage from the FPGA, these PROMs enable faster, more reliable multi-FPGA configuration chains in production systems.
Key features of the EPC16QI100 include a 33 MHz serial configuration interface, hardware compliance with the IEEE Std. 1532 in-system programmability (ISP) specification, Jam STAPL programming support, JTAG boundary-scan testability, and a dedicated nINIT_CONF pin that triggers a private JTAG instruction to start FPGA configuration. The 16 Mb density is sufficient for configuring the largest Altera FPGA families of its generation. An external 33 MHz oscillator provides the configuration clock reference.
Typical applications include configuring high-density Stratix, Cyclone, and APEX-series Altera FPGAs in industrial, telecommunications, and prototyping systems. The 100-pin PQFP package and 3.3 V operation simplify board integration into legacy through-hole and mixed-technology designs where surface-mount BGA configuration parts are not desirable.

主な用途
EPC16QI100 の用途: 6 件s: High-Density Altera FPGA Configuration, Telecommunications Base-Station Controllers, Industrial Control and Factory Automation, Military and Aerospace Avionics (Legacy Programs), Medical Imaging Equipment, Test and Measurement Instrumentation.
High-Density Altera FPGA Configuration
The EPC16QI100 stores the bitstream and configures very high-density Altera FPGAs at power-up via its 33 MHz serial interface. Its 16 Mb capacity comfortably fits the largest Altera bitstreams of its era, including Stratix and APEX families. The dedicated configuration controller offloads bitstream management from the host processor, and the nINIT_CONF pin enables JTAG-initiated configuration without external logic. Industrial temperature grade (-40 °C to +85 °C) supports factory-floor deployment.
おすすめ
Telecommunications Base-Station Controllers
Telecommunications base-station and line-card designs use the EPC16QI100 to boot multi-FPGA signal-processing fabrics in a defined order. The 3.3 V single-rail supply simplifies board design in space-constrained ATCA/AdvancedTCA shelves, and the JTAG interface allows field firmware updates without removing boards. The IEEE 1532 ISP compliance enables standardized in-system programming during manufacturing and field service. Industrial temperature rating covers outdoor cabinet installations.
おすすめ
Industrial Control and Factory Automation
Factory-automation controllers use the EPC16QI100 to configure FPGA-based motion-control and machine-vision subsystems that demand deterministic boot times. The 33 MHz configuration clock enables sub-second FPGA configuration, minimizing production-line startup delay. The -40 °C to +85 °C industrial temperature range tolerates unheated cabinet environments, and the PQFP package suits through-hole-friendly backplanes where BGA parts are unsuitable. JTAG ISP supports post-assembly programming.
おすすめ
Military and Aerospace Avionics (Legacy Programs)
Long-lifecycle military and aerospace programs continue to specify the EPC16QI100 because the part is qualified in legacy system designs and the PQFP package withstands the through-hole-friendly board stacks favored in older avionics. The industrial temperature grade covers many avionics bay environments, and the JTAG/IEEE 1532 ISP allows depot-level firmware updates. For new programs, designers should verify Altera/Intel FPGA lifecycle policy before committing.
おすすめ
Medical Imaging Equipment
Medical imaging systems (ultrasound, CT, MRI front-ends) historically used Altera FPGAs and the EPC16QI100 to load configuration bitstreams for image-acquisition pipelines. The deterministic 33 MHz serial configuration stream supports predictable boot sequences required for medical safety certification, and the dedicated nINIT_CONF pin enables the host MCU to trigger FPGA configuration cleanly. Designers of new equipment should consider modern equivalents due to obsolete lifecycle status.
おすすめ
Test and Measurement Instrumentation
Test and measurement instruments (logic analyzers, oscilloscopes, protocol testers) use the EPC16QI100 to configure FPGAs that implement high-speed signal-acquisition and pattern-generation logic. The 33 MHz configuration clock minimizes boot time on production test floors, and the JTAG boundary-scan supports in-circuit test (ICT) for manufacturing defect screening. Industrial temperature rating covers typical lab and factory environments.

主な差別化要因
- Drop-in lead-free upgrade available （vs EPC16QI100 (this part, leaded) vs EPC16QI100N)
- Industrial temperature grade for harsh environments （vs EPC16QC100 (commercial) vs EPC16QI100 (industrial))
- 16 Mb density is sweet spot for legacy high-density FPGAs （vs EPC160I100 (160 Mb) vs EPC16QI100 (16 Mb))
設計ノート
The EPC16QI100 operates from a single 3.3 V rail with a permitted range of 3.0 V to 3.6 V. Decouple VCC pins with 0.1 µF ceramic capacitors placed as close as possible to each supply pin, and add a single bulk 10 µF tantalum or ceramic capacitor near the package. The VPP programming voltage pin should be tied to VCC through a 1 kΩ resistor or left open in user-mode operation - consult the datasheet before applying ISP programming.
Route the DCLK trace as a 50 Ω controlled-impedance microstrip or stripline and keep it matched in length to the DATA trace (within 1 cm) to avoid configuration setup/hold violations. Place the EPC16QI100 within 5 cm of the target FPGA to minimize signal-integrity degradation; longer distances require buffering. The JTAG chain (TCK/TMS/TDI/TDO) should be daisy-chained with no stubs, and a 10 kΩ pull-up on TCK/TMS/TDI and a 10 kΩ pull-down on nCONFIG/nCE is recommended.
Do not confuse EPC16QI100 (industrial) with EPC16QC100 (commercial) - the wrong temperature grade will fail early-life in unheated enclosures. The 'N' suffix (EPC16QI100N) denotes lead-free assembly required for RoHS compliance in new designs. Daisy-chaining multiple EPC16QI100 devices to configure one FPGA requires nCEO of the upstream device to drive nCE of the next; do not leave nCEO floating. Finally, verify FPGA bitstream size < 16 Mb before committing to this part.
コンプライアンス情報
EPC16QI100 is the leaded (non-RoHS) variant - choose EPC16QI100N for RoHS compliance. The 'N' suffix in the EPC16 family denotes lead-free assembly. AEC-Q100 is not applicable - this is a memory/configuration device, not an automotive analog/power IC. Confirm specific REACH and conflict-minerals status with the distributor before procurement.
