EPC16QC100T 概要
An FPGA configuration PROM is a non-volatile serial memory device that retains bitstream data when power is removed and serially delivers that data to the FPGA during power-up. Configured via JTAG (IEEE 1149.1 boundary-scan), EPC16 PROMs replace legacy EPC1/EPC2 devices and serve as the configuration memory backplane for older Altera FPGA designs that lack integrated flash memory.
Key features include a 16 Mbit storage capacity, 3.3V single-supply operation, JTAG-based in-system programmability, support for daisy-chaining multiple PROMs for higher-density designs, and compatibility with Altera Quartus II configuration flows. The device operates across the industrial 0C to +70C temperature range, with the 'T' suffix denoting tape-and-reel packaging.
Internally, the EPC16QC100T employs a flash-based memory array with a dedicated controller managing JTAG and serial FPGA interfaces (nSTATUS, nCONFIG, DCLK, DATA0). The decompression engine minimizes PROM-to-FPGA transfer time and reduces the PCB area required for configuration storage. The PQFP-100 footprint is widely documented and supported by legacy Altera reference designs.
Typical applications include legacy Cyclone/Stratix/ACEX FPGA boot configuration, industrial control cards using older Altera FPGAs, test and measurement hardware, and telecommunications backplane cards. The JTAG ISP feature allows in-field firmware updates without removing the PROM from the board.
When designing with the EPC16QC100T, ensure that the nSTATUS/nCONFIG timing requirements of the target FPGA are respected. The maximum DCLK frequency is limited by the connected FPGA's configuration controller; refer to the target FPGA datasheet for the exact DCLK ceiling. For higher density needs, multiple EPC16 devices can be cascaded.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the original Altera datasheet, helping sourcing engineers evaluate longevity and replacement options for legacy designs.

主な用途
EPC16QC100T の用途: 7 件s: Legacy Cyclone FPGA Boot Configuration, Stratix FPGA Multi-Device Configuration, Industrial Control & Factory Automation Cards, Telecommunications Backplane Equipment, Test & Measurement Instrumentation, Military & Aerospace Legacy Systems, Medical Imaging Equipment.
Legacy Cyclone FPGA Boot Configuration
The EPC16QC100T stores the configuration bitstream for legacy Altera Cyclone (EP1C3/EP1C6/EP1C12/EP1C20) FPGAs that lack on-chip configuration memory. During power-up, the PROM serially shifts bitstream data to the FPGA via DCLK/DATA0 with nSTATUS/nCONFIG handshaking. Its 16 Mbit capacity with built-in 35% decompression accommodates Cyclone bitstreams comfortably, while the 3.3V single-supply aligns with Cyclone core voltage rails, simplifying board power architecture. Engineers value the JTAG ISP for in-field firmware updates without removing the PROM from the board.
おすすめ
Stratix FPGA Multi-Device Configuration
The EPC16QC100T can be daisy-chained with additional EPC16 PROMs to support larger Stratix (EP1S10/EP1S25/EP1S40) FPGA configuration bitstreams exceeding 16 Mbit. In multi-PROM chains, the master EPC16 orchestrates the configuration sequence and passes control to downstream PROMs via cascaded nCASC and DATA signals. The device's 100-pin PQFP footprint offers reliable through-hole-compatible surface-mount soldering for industrial backplane designs where mechanical robustness is required. Cascade configuration eliminates external flash memory.
おすすめ
Industrial Control & Factory Automation Cards
The EPC16QC100T is commonly deployed in industrial control PLCs, motion controller cards, and factory automation hardware that uses Altera ACEX or APEX FPGAs for parallel I/O handling. The PROM's commercial 0C to +70C operating range suits cabinet-mounted equipment; for harsh industrial environments, the EPC16QC100II variant extends the range to -40C to +85C. The JTAG ISP allows field technicians to push bitstream updates over boundary-scan chains without opening enclosures, reducing maintenance windows.
おすすめ
Telecommunications Backplane Equipment
In telecom backplane cards built around legacy Altera Stratix GX or Cyclone II FPGAs, the EPC16QC100T provides the boot configuration storage while the FPGA handles high-speed SERDES and packet processing. The PROM's serial interface is bandwidth-acceptable for one-time configuration at power-up. Multi-device cascade support is critical because Stratix GX bitstreams often exceed the 16 Mbit threshold. The PQFP-100 package's proven long-term reliability has made it a trusted choice in carrier-grade telecom hardware.
おすすめ
Test & Measurement Instrumentation
Test and measurement instruments (oscilloscopes, logic analyzers, signal generators) that use Altera FPGAs for DSP and timing rely on the EPC16QC100T for reliable configuration storage across power cycles. The PROM's commercial temperature range suits laboratory environments, and the JTAG ISP enables ATE-based pre-programming during manufacturing. Decompression support accelerates the configuration time, reducing instrument boot latency. The PQFP-100 package also supports manual rework for low-volume production.
おすすめ
Military & Aerospace Legacy Systems
Defense and aerospace programs that have legacy Altera ACEX 1K/2K FPGA designs continue to specify the EPC16QC100T due to its stable, long-lifecycle silicon. The part's PQFP-100 footprint is well-documented in dozens of fielded military programs. For extended-temperature military applications, the EPC16QC100II industrial variant is preferred; otherwise the commercial-temperature EPC16QC100T serves ground-based systems. Compliance with MIL-STD-883 may require up-screening, which should be coordinated with the procurement authority.
おすすめ
Medical Imaging Equipment
Medical imaging systems (ultrasound, MRI, CT scanners) with long product lifecycles use the EPC16QC100T to configure Altera Cyclone II or Stratix FPGAs that drive beam-forming and image reconstruction pipelines. The PROM's stable supply chain through 2026 and known reliability profile suit regulated medical device workflows. JTAG ISP supports field firmware updates under medical device change-control procedures, while the PQFP-100 package's established soldering processes help maintain ISO 13485 manufacturing compliance.

設計ノート
Estimated: The EPC16QC100T operates from a single 3.3V supply; VCC pins are distributed across the PQFP-100 package (pins 12, 14, 16, ..., 100) and each must be decoupled with a 0.1uF ceramic capacitor placed within 5mm of the package. Bulk 10uF tantalum decoupling at the PROM supply pin improves noise immunity during FPGA configuration. The VCC ramp must be monotonic per Altera specification to avoid PROM corruption during initialization.
Route the DCLK and DATA0 traces between the EPC16QC100T and the target FPGA as a controlled-impedance differential pair (or closely-matched length-matched single-ended traces) to minimize skew. The nSTATUS and nCONFIG signals are open-drain and require 4.7kohm pull-up resistors to VCC. Avoid routing JTAG signals (TDI/TDO/TMS/TCK) near high-speed switching clocks to prevent ISP programming failures.
The most common design pitfall when using the EPC16QC100T is incorrect cascade configuration: when daisy-chaining multiple PROMs, the nCASC pin must connect to the nCE pin of the downstream PROM with a 1kohm pull-up. Failing to cascade correctly causes the downstream PROMs to enter undefined states. Also note that the EPC16QC100T is NRND; for new designs, Intel recommends migrating to EPCQ-L or EPCQ-A series configuration devices in 8-pin SOIC, which requires PCB redesign.
The PQFP-100 package has 0.5mm lead pitch and requires precise land pattern design with non-solder-mask-defined (NSMD) pads for reliable solder joints. Use a reflow profile compliant with JEDEC J-STD-020 MSL-3 (245C peak for 60 seconds max). For prototype or low-volume builds, the through-hole-compatible PQFP footprint allows hand-soldering with proper technique, but production assemblies should use automated pick-and-place.
コンプライアンス情報
Compliance status varies by date code and lot. The EPC16QC100T pre-dates widespread RoHS adoption; verify per-unit RoHS compliance with distributor before purchase. Not AEC-Q100 qualified; not automotive-grade.
