EPC16QC100N Présentation
What is an FPGA configuration PROM? An FPGA configuration PROM is a non-volatile flash memory device that stores the bitstream (configuration data) for SRAM-based FPGAs. Because SRAM loses its configuration when power is removed, an external non-volatile store is required to reload the device at every power-up. These configuration PROMs sit in the hierarchy as follows: configuration PROM -> serial/parallel flash memory -> non-volatile memory -> memory IC -> integrated circuit (semiconductor). They expose a dedicated configuration interface (DATA, DCLK, nCONFIG, nSTATUS, CONF_DONE) that handshakes directly with the FPGA during the load sequence.
Key features include 16,777,216 bits of flash memory (16 Mbit), on-chip decompression that supports compressed bitstreams up to twice the memory density, and a fast page-mode configuration interface. The device supports JTAG-based in-system programming via IEEE Std 1149.1, allowing the configuration image to be updated on a populated PCB without removing the PROM. Operating temperature is specified for the commercial 0C to 70C range.
The EPC16QC100N uses a flash-based architecture with a typical 90 ns access time, providing approximately 10 MHz flash read bandwidth. The 16-bit DQ flash data bus delivers up to 160 Mbps of bandwidth, which is more than sufficient for legacy Altera configuration schemes but lower than what modern Stratix FPP (Fast Passive Parallel) modes require at high clock rates.
Typical applications include FPGA configuration storage on industrial control boards, telecommunications line cards using Stratix or Cyclone devices, test and measurement chassis that require in-field bitstream updates, and legacy designs that pair ACEX 1K or APEX 20K devices with a parallel configuration PROM. The wide 3.0V to 3.6V supply range also suits +3.3V system rails common in telecom infrastructure.
When designing with this device, ensure that the configuration mode of the target FPGA is compatible with the EPC16QI100N's supported modes (FPP, PS, AS). The nINIT_CONF pin allows the FPGA to delay configuration start; leave it pulled high through a 10 kohm resistor if unused. Verify that the bitstream fits in 8 Mbit uncompressed or 16 Mbit compressed.

Applications typiques
EPC16QC100N convient pour 6 applications: FPGA Configuration Storage on Industrial Control Boards, Telecommunications Line Card Bitstream Storage, Test and Measurement Chassis with In-Field Updates, Legacy ACEX 1K and APEX 20K Board Refresh, Aerospace and Defense Avionics with In-System Reprogramming, Medical Imaging Equipment FPGA Boot.
FPGA Configuration Storage on Industrial Control Boards
The EPC16QC100N stores 16 Mbit of configuration bitstream for SRAM-based Altera FPGAs such as Cyclone II and Stratix on industrial control boards. With 3.0 V to 3.6 V supply operation and JTAG-based in-system programming per IEEE 1149.1, the device enables field firmware updates without removing the PROM from the PCB. The 33 MHz configuration clock supports standard FPP and PS configuration modes, while the 100-pin PQFP (20x14 mm) package fits legacy control-card layouts where board real estate is plentiful.
Recommandé
Telecommunications Line Card Bitstream Storage
In telecom line cards that pair Stratix or APEX 20K FPGAs with external configuration memory, the EPC16QC100N delivers reliable non-volatile bitstream storage. Its 16 Mbit capacity accommodates compressed bitstreams up to approximately 32 Mbit thanks to on-chip decompression, which is essential for line cards running large protocol stacks. The device's 90 ns flash access time and 160 Mbps DQ bandwidth comfortably meet the configuration throughput required by legacy Stratix FPP at 33 MHz.
Recommandé
Test and Measurement Chassis with In-Field Updates
Test and measurement instruments frequently require in-field bitstream updates as engineers add new measurement routines or calibration procedures. The EPC16QC100N's JTAG in-system programming lets designers rewrite the configuration image on a populated chassis without removing the PROM, dramatically simplifying field service. The 16 Mbit capacity suits mid-density Stratix II and Cyclone II designs common in modular instruments, while the 100-pin PQFP package survives multiple reflow cycles when boards need rework.
Recommandé
Legacy ACEX 1K and APEX 20K Board Refresh
Designers maintaining legacy ACEX 1K and APEX 20K boards often need a pin-compatible configuration PROM that remains available for reorders. The EPC16QC100N fits this exact role, sharing the 100-pin PQFP footprint and Altera's dedicated FPGA configuration interface with older designs. With on-chip decompression enabled, the 16 Mbit flash stores compressed bitstreams for these legacy families, extending the service life of installed equipment without a board respin.
Recommandé
Aerospace and Defense Avionics with In-System Reprogramming
Avionics subsystems based on radiation-tolerant or ruggedized Altera FPGAs benefit from the EPC16QC100N's in-system programming capability for mission-profile updates. The 16 Mbit density supports modern waveform processing bitstreams while the JTAG interface enables secure firmware updates under controlled maintenance windows. Designers route TCK/TMS/TDI/TDO to a chassis test connector, allowing ground crews to rewrite the configuration without unseating the PROM from the avionics module.
Recommandé
Medical Imaging Equipment FPGA Boot
Medical imaging platforms such as ultrasound carts and portable X-ray units use Altera FPGAs for real-time signal processing, and the EPC16QC100N provides reliable boot storage for these mission-critical designs. The 3.3 V supply aligns with medical equipment rails, while the 16 Mbit density accommodates the larger bitstreams of Stratix II imaging pipelines. JTAG ISP allows field service engineers to update the imaging algorithm firmware without disassembling the cart, accelerating maintenance turnaround.

Principaux différenciateurs

- Largest 16 Mbit capacity in the EPC family with on-chip decompression (vs EPC8QC100N)
- Pin-compatible upgrade path to industrial grade without PCB rework (vs EPC16QI100N)
- JTAG in-system programming eliminates socket rework (vs EPC16JC88 (military grade))
Notes de conception
The EPC16QC100N draws active configuration current during the FPGA bitstream load, then drops to a low standby value once nSTATUS rises. Decouple each VCC pin with a 0.1 uF X7R ceramic placed within 5 mm of the package, and add a single 10 uF tantalum or ceramic bulk capacitor near the center of the device. On 3.3 V rails that also feed the FPGA, isolate the configuration PROM with a ferrite bead to prevent inrush noise during load from corrupting other logic.
Place the EPC16QC100N close to the target FPGA's configuration pins to minimize the DCLK and DATA trace lengths. Route DCLK with a characteristic impedance of 50 ohm and length-match DATA[15:0] within 100 mils to keep the 16-bit parallel bus aligned. Provide a JTAG header on the board that brings out TCK, TMS, TDI, TDO plus GND, allowing in-system updates with a Quartus Programmer without disassembling the chassis.
Do not assume any PQFP-100 footprint is compatible - the EPC16QC100N uses a JEDEC MS-026-compliant 100-pin PQFP (20x14 mm body). The EPC16UC88N listed as a BGA-100 alternative is NOT drop-in and requires PCB rework. When migrating to the EPC16QI100N industrial variant, double-check that your FPGA's configuration mode (FPP, PS, AS) is supported - the datasheet specifies FPP and PS for the EPC16 family. Always regenerate the programming file in Quartus when switching density steps (EPC8 to EPC16).
Estimated: at 3.3 V supply and 33 MHz configuration clock during a typical 100 ms bitstream load, the EPC16QC100N draws approximately 50 mA active. That yields roughly 165 mW of dissipation. After configuration completes, standby current drops to a few hundred microamps, so thermal stress is negligible. No external heatsink or thermal copper pour beyond standard ground fill is required for the 100-pin PQFP package.
