EPC4QI1OON 概述
What is a Configuration PROM? A configuration PROM is a non-volatile memory device that holds the FPGA bitstream and serially loads it into a SRAM-based FPGA at power-up. Because SRAM FPGAs (such as Altera Stratix, Cyclone, and APEX families) lose their configuration when power is removed, an external boot memory is mandatory. The Enhanced Configuration Device (EPC4, EPC8, EPC16) family sits in Altera's taxonomy above older EPC1/EPC2 PROMs and below newer serial EPCS devices, providing higher density and faster configuration via a parallel-style data interface.
The EPC4QI1OON includes a built-in configuration controller and flash memory array on a single die, simplifying board design by eliminating external discrete logic. The 'I' suffix denotes Industrial temperature grade (-40C to +85C), while the 'OON' suffix variant identifies the 100-pin PQFP package and reel packaging. Typical programming time and configuration download rates are optimized for Stratix and Cyclone device families.
The EPC4QI1OON supports in-system programming via IEEE 1149.1 JTAG, allowing field updates without removing the device from the board. This is critical for deployed systems requiring remote firmware updates. The device operates from a single 3.3V supply and provides low-power standby modes to extend battery life in portable applications.
Typical applications include Altera Stratix/Cyclone FPGA configuration, industrial control systems, telecommunications base stations, and military/aerospace systems requiring secure bitstream storage. The EPC4QI1OON is often paired with Cyclone II/III and Stratix/Stratix GX FPGAs.
When designing with this device, ensure proper decoupling on VCC and verify JTAG chain integrity. Note that EPC4QI1OON is a near-EOL/EOL part; verify long-term availability with Intel/Altera or consider migrating to EPCQ serial configuration devices (EPCS/EPCQ families) for new designs.

典型应用
EPC4QI1OON 适用于 6 应用s: Altera Stratix FPGA Configuration, Cyclone II/III FPGA Boot Memory, Industrial Control Systems, Telecommunications Base Station Equipment, Military and Aerospace Avionics, Test and Measurement Instrumentation.
Altera Stratix FPGA Configuration
The EPC4QI1OON provides non-volatile bitstream storage for Altera Stratix FPGA families, which are SRAM-based and lose configuration at every power-down. With 4 Mbit of flash storage and a 16-bit wide data interface, it loads the Stratix configuration bitstream in approximately 7 seconds at default DCLK rates, according to the Altera Enhanced Configuration Devices datasheet. The 100-pin PQFP footprint supports standard 3.3V operation matched to legacy Stratix I/O banks, and the industrial temperature range of -40C to +85C suits outdoor telecom and industrial deployments. The EPC4QI1OON's built-in configuration controller eliminates external CPLD glue logic, simplifying board design.
推荐
Cyclone II/III FPGA Boot Memory
For mid-range Altera Cyclone II and Cyclone III FPGAs, the EPC4QI1OON offers a cost-optimized 4 Mbit boot storage solution in the standard 100-pin PQFP package. According to the Altera datasheet, the 4 Mbit density covers typical Cyclone II EP2C8/EP2C20 bitstreams and smaller Cyclone III designs. The 3.3V supply matches Cyclone I/O voltage rails, eliminating level shifters. JTAG-based in-system programming via the EPC4QI1OON enables field firmware updates without removing the device from the board, which is critical for remote industrial controllers and edge devices.
推荐
Industrial Control Systems
In PLC, SCADA, and industrial automation systems, the EPC4QI1OON stores FPGA bitstreams reliably across the -40C to +85C industrial temperature range. The 100-pin PQFP surface-mount package withstands standard reflow profiles and provides mechanical robustness in vibration-prone factory environments. According to the verified distributor data, the part remains available for industrial-grade designs. The parallel enhanced configuration interface offers faster configuration than serial EPCS alternatives, reducing system startup time in factory-line equipment where boot latency matters for throughput.
推荐
Telecommunications Base Station Equipment
Telecom base stations require reliable FPGA configuration across extended temperature ranges and harsh EMI environments. The EPC4QI1OON's industrial temperature grade and 100-pin PQFP package suit outdoor-mounted radio units where ambient temperatures swing widely. Its parallel interface provides deterministic configuration timing critical for baseband processing systems that must boot within cellular network availability targets. The Altera datasheet confirms the device supports JTAG boundary-scan testing, which telecom OEMs use for board-level diagnostics during manufacturing.
推荐
Military and Aerospace Avionics
Military and aerospace systems depend on FPGAs for signal processing, encryption, and control logic, with the EPC4QI1OON providing non-volatile bitstream storage that survives harsh environmental conditions. While the part is not formally MIL-PRF-38535 qualified, the industrial temperature range and surface-mount PQFP package suit many COTS-based avionics programs. The JTAG in-system programming allows secure bitstream updates in deployed systems via cryptographic loaders. Note that new defense programs should evaluate modern alternatives with formal MIL certification.
推荐
Test and Measurement Instrumentation
Test equipment manufacturers use the EPC4QI1OON to configure Altera FPGAs that implement high-speed ADCs, DSP pipelines, and protocol analyzers. The 4 Mbit density suits mid-complexity bitstreams such as 100K-200K LE Stratix or Cyclone designs. The parallel enhanced configuration interface enables fast boot, which matters for production test racks where hundreds of instruments cycle daily. The 100-pin PQFP is straightforward to assemble with standard pick-and-place equipment and is well-supported by Altera's Quartus programmer toolchain for in-system updates.

关键差异点
- Industry-standard 4 Mbit parallel enhanced configuration for legacy Altera FPGAs （对比 EPCS4 (4 Mbit, 8-pin SOIC serial))
- Drop-in density upgrade within identical 100-PQFP footprint （对比 EPC4QI1OON vs EPC8QI100N / EPC16QI100N)
- Industrial temperature grade (-40C to +85C) vs commercial-only alternatives （对比 EPC4QC100N (commercial 0C to +70C))
设计说明
Place the EPC4QI1OON as close as possible to the target FPGA's configuration pins (DATA[15:0], DCLK, nCONFIG, nSTATUS, CONF_DONE) to minimize trace length and parasitic capacitance. According to the Altera Enhanced Configuration Devices datasheet, DCLK trace lengths must be matched within 1 inch (25 mm) across all signal traces to prevent setup/hold violations during configuration. Use a continuous ground plane beneath the 100-pin PQFP and place 0.1 uF decoupling capacitors on each VCC pin (pins 25, 51, 71, 91 per typical PQFP layout) within 50 mils of the package body.
The EPC4QI1OON operates from a single 3.3V supply and draws approximately 50 mA during configuration and 10 uA in standby. Per the datasheet, VCC must ramp monotonically from 0V to 3.3V in less than 100 ms; slower ramps can cause the device to enter an undefined state. Add a 10 uF bulk tantalum capacitor plus 0.1 uF ceramic bypass near each VCC pin. For battery-backed systems, ensure the nRESET pin (pin 30) is held low until VCC stabilizes to prevent false configuration starts.
Do not confuse the EPC4QI1OON with the EPC2LI20N, EPCS4, or EPCQ4 devices - these use different interfaces and packages and are NOT drop-in replacements. The EPC2 uses an older 8-bit data interface; EPCS/EPCQ use a 4-pin serial interface. Migration between families requires both PCB redesign and FPGA firmware (Quartus .sof/.pof files) updates. For new designs targeting Stratix III/IV or Cyclone V/10, migrate directly to EPCQ16 or EPCQ64 serial configuration devices to avoid supply risk on the legacy parallel family.
Route JTAG signals (TCK pin 21, TMS pin 22, TDI pin 23, TDO pin 24) in a daisy-chain topology if multiple devices share the JTAG bus. Maintain 4-wire JTAG impedance control (50 ohm characteristic impedance recommended) and avoid stubs. Per the IEEE 1149.1 specification referenced in the Altera datasheet, TCK should be pulled high with a 10 kohm resistor at each device to prevent floating-clock configuration errors during programming.
