EPC8QC100 Visão geral
An FPGA configuration PROM is a specialized non-volatile serial/parallel memory device that stores the bitstream used to program an FPGA at power-up. Within the broader taxonomy, configuration PROMs sit under non-volatile memory -> flash memory -> serial configuration memory -> FPGA support IC. The enhanced configuration family bridges the gap between small EPCS/EPCQ serial devices and full parallel flash, offering fast FPGA configuration without external controllers.
Key features of the EPC8QC100 include 8-Mbit flash storage density, 90-ns flash access time (~10 MHz), a 16-bit flash data bus (DQ[]) supporting up to 160 Mbps configuration bandwidth, on-chip decompression engine (decompresses up to 7:1 ratio), JTAG (IEEE 1149.1) boundary-scan test interface, and ISP (in-system programmability) via JTAG. The device operates from a 3.3V core supply and supports commercial temperature grade (0C to +70C).
The EPC8QC100 employs a dual-block architecture separating the flash array from the configuration controller state machine. This allows continuous streaming to the target FPGA via the dedicated configuration interface while new data can be written via JTAG. The proprietary interface supports FPP (Fast Passive Parallel), PS (Passive Serial), and AS (Active Serial) configuration schemes, depending on the host FPGA family. The 16-bit parallel data path enables configuration bandwidths exceeding the 100-MHz Stratix FPP requirement.
Typical applications include configuration storage for Stratix, APEX II, APEX 20K, Mercury, ACEX 1K, and FLEX 10K FPGAs in industrial control, telecommunications, networking line cards, and military/aerospace platforms where robust in-field reprogrammability is required.
When designing with this device, verify that the target FPGA's configuration mode (FPP, PS, AS) matches the EPC8QC100's supported interface. Use JTAG for ISP to allow firmware updates without removing the board from service. Decoupling: place 0.1uF ceramic capacitors close to all VCC pins.

Aplicações típicas
EPC8QC100 é adequado para 6 aplicaçãos: Stratix FPGA Configuration Storage, APEX II / APEX 20K FPGA Configuration, Industrial Control System FPGA Boot, Telecom Line Card Configuration, Military/Aerospace FPGA Systems, Test & Measurement Instrument Configuration.
Stratix FPGA Configuration Storage
The EPC8QC100 stores the Stratix FPGA configuration bitstream in 8 Mbit of flash memory, delivering it to the FPGA via the 16-bit parallel DQ[] bus at up to 160 Mbps. The 90 ns flash access time supports 100-MHz Stratix FPP configuration per the Altera Enhanced Configuration Devices datasheet. Decompression up to 7:1 allows larger uncompressed bitstreams to fit in the 8 Mbit array. ISP via JTAG enables in-field firmware updates without board removal, critical for telecom line cards where downtime is costly.
Recomendado
APEX II / APEX 20K FPGA Configuration
For APEX II and APEX 20K FPGAs, the EPC8QC100 provides compressed configuration via FPP or PS modes using the 16-bit DQ[] interface. The 8 Mbit flash density matches typical APEX 20K bitstream sizes (5-7 Mbit uncompressed, fitting comfortably with compression enabled). The 100-PQFP footprint allows direct mounting on legacy APEX 20K boards, supporting both prototyping and production volumes. The JTAG ISP interface enables factory and field programming without external proctors.
Recomendado
Industrial Control System FPGA Boot
In industrial automation and process control systems, the EPC8QC100 reliably boots ACEX 1K and FLEX 10K FPGAs at power-up. The commercial 0C to +70C temperature range suits factory-floor environments inside sealed enclosures. The 3.3V supply integrates cleanly with 3.3V digital logic rails common in industrial PLCs. The JTAG ISP interface allows remote firmware updates over industrial Ethernet bridges, supporting IEC 61131-style system modernization without physical board access.
Recomendado
Telecom Line Card Configuration
Telecommunications line cards based on Stratix or APEX 20K FPGAs use the EPC8QC100 to store multiple firmware images and configuration revisions. The 8 Mbit flash supports golden-image plus field-upgrade image storage, with JTAG ISP enabling remote bitstream updates via embedded management controllers. The 100-PQFP package provides robust thermal performance for the enclosed, often fanless, NEBS-compliant chassis environment where these cards operate.
Recomendado
Military/Aerospace FPGA Systems
Defense and aerospace systems based on radiation-tolerant FLEX 10K or APEX 20K FPGAs benefit from the EPC8QC100's robust configuration delivery and ISP capability. The non-volatile flash storage retains configuration through power cycles and brown-out events. JTAG ISP enables pre-deployment firmware updates and post-deployment configuration changes. Note: industrial temperature variant EPC8QI100 (-40C to +85C) is preferred for harsh-environment applications.
Recomendado
Test & Measurement Instrument Configuration
Test and measurement instruments (oscilloscopes, logic analyzers, signal generators) using Stratix or APEX 20K FPGAs for DSP and signal acquisition leverage the EPC8QC100 for reliable configuration storage. The JTAG ISP interface simplifies factory calibration and field firmware updates, allowing manufacturers to ship instruments with upgradeable feature sets. The 16-bit parallel configuration bus minimizes FPGA boot time, reducing instrument startup delays in production test environments.

Notas de projeto
The EPC8QC100 operates from a single 3.3V supply (3.0-3.6V range per Altera datasheet). Decoupling: place a 0.1uF ceramic capacitor close to each VCC pin with a low-impedance ground return to handle flash programming current transients. During JTAG ISP, peak current can spike during sector erase and program operations - bulk decoupling (4.7uF to 10uF tantalum or ceramic) near the device is recommended.
Do not confuse EPC8QC100 (parallel enhanced configuration PROM) with EPCS-series (serial configuration memory) or EPCQ-series (active serial). The configuration protocols are not interchangeable: EPC8QC100 uses FPP/PS parallel mode with 16-bit DQ[] bus, while EPCS/EPCQ use single-wire AS mode. Connecting an EPC8QC100 to a Cyclone/Stratix AS configuration pinout will not work. Always verify the target FPGA's configuration mode matches the PROM's interface.
Route the 16-bit DQ[] configuration bus with matched trace lengths to the target FPGA configuration pins to avoid setup/hold violations at high FPP clock rates. Place the EPC8QC100 close to the FPGA to minimize bus loading. JTAG signals (TCK, TMS, TDI, TDO) should be routed with consideration for the daisy-chain topology - include proper pull-ups on TMS and TDI per IEEE 1149.1 recommendations.
