EPC4Q100T - 4Mb Enhanced Configuration Device, 100-PQFP | Intel
MPN: EPC4Q100T ✗ Cuối đờiEPC4Q100T Tóm tắt
What is an Enhanced Configuration Device? An EPC device is a non-volatile flash memory plus controller subsystem that holds an FPGA's configuration bitstream. When the host system powers up, the EPC device automatically loads the bitstream into the attached SRAM-based FPGA through a dedicated configuration port (PS, FPP, or AS mode). This eliminates the need for a separate boot PROM and enables remote in-system reprogramming over JTAG. EPC devices sit hierarchically between raw configuration PROMs and full embedded controllers in the FPGA configuration ecosystem.
Key features of the EPC4Q100T include 4 Mbit of flash storage, 90-ns flash access time (approximately 10 MHz core clock), and a 16-bit data bus (DQ[15:0]) that supports FPP configuration at speeds up to 160 Mbps. The device supports in-system programmability via JTAG (IEEE 1149.1 boundary scan), enabling field firmware updates without removing the FPGA board. Operating voltage is 3.3 V core with 5 V tolerant I/O on legacy interfaces.
The EPC4Q100T uses a 90-nm (or equivalent process node) flash cell array paired with an internal controller that handles page-mode reads and JTAG-driven updates. The internal oscillator and state machine generate configuration clock and control signals (nSTATUS, CONF_DONE, nCONFIG) to the FPGA without external glue logic, simplifying board design.
Typical applications include Stratix and Cyclone FPGA boot storage, industrial control boards with field-updatable firmware, telecommunications line cards requiring remote bitstream updates, and prototyping platforms where multiple bitstreams must be switched in the lab. The device is widely used in legacy Altera/Intel designs where a drop-in configuration memory is needed.
When designing with EPC4Q100T, ensure JTAG chain integrity for in-system programming and observe the configuration mode (PS vs FPP vs AS) pins to match the target FPGA. For new designs, Intel recommends migrating to the newer EPCQ-A or EPCQ-L configuration devices in smaller packages.

Ứng dụng tiêu biểu
EPC4Q100T phù hợp cho 6 Áp dụngs: Stratix FPGA Boot Configuration, Cyclone FPGA Configuration Memory, Telecommunications Line Card Firmware Storage, Industrial Control Board Bitstream Storage, FPGA Prototyping Platform Bitstream Switching, Legacy APEX FPGA Configuration Subsystem.
Stratix FPGA Boot Configuration
The EPC4Q100T's 4 Mbit flash storage and 16-bit DQ bus are ideal for Stratix FPGA boot configuration on legacy Altera/Intel boards. Its 160 Mbps FPP data rate matches Stratix configuration bandwidth requirements without throughput bottleneck. Placed between the 3.3 V system rail and the Stratix configuration port (nCONFIG/nSTATUS/CONF_DONE), the EPC4Q100T streams the bitstream at power-up. Unlike a separate boot PROM, the EPC4Q100T requires no external controller because the internal state machine generates all FPGA hand-shake signals. This makes it suitable for industrial control boards and telecom line cards based on first-generation Stratix devices, where a compact 100-PQFP footprint (20x14 mm) is already laid out and field-replacement of legacy inventory is required.
Được đề xuất
Cyclone FPGA Configuration Memory
The EPC4Q100T is widely deployed as the configuration memory for Cyclone-series FPGAs on cost-sensitive industrial and consumer boards. Its 4 Mbit density is sufficient for most Cyclone compressed bitstreams (EP1C3, EP1C6, EP1C12 families). The JTAG-based in-system programmability (IEEE 1149.1) lets engineers update firmware in the field without removing the board. Placed near the Cyclone configuration pins, the EPC4Q100T operates from the 3.3 V rail with 5 V tolerant legacy interfaces. For new Cyclone designs in 2026, EPCQ-A or EPCQ-L devices are recommended, but the EPC4Q100T remains a drop-in choice for existing boards with the 100-PQFP footprint already committed.
Được đề xuất
Telecommunications Line Card Firmware Storage
The EPC4Q100T is suited to telecommunications line cards where remote firmware updates are required. Its 4 Mbit flash holds the Stratix or APEX configuration bitstream plus optional checksum, and the JTAG interface allows the central office to reprogram the FPGA without board removal. The device's 100-PQFP industrial-grade packaging tolerates the thermal environment of central-office racks. Placed on the line-card PCB near the JTAG header, the EPC4Q100T shares a 3.3 V supply rail with the FPGA. Compared to a discrete boot PROM, it eliminates external glue logic and reduces BOM cost by integrating the configuration state machine, making it a proven choice for legacy telecom infrastructure.

Industrial Control Board Bitstream Storage
The EPC4Q100T provides reliable non-volatile bitstream storage for industrial control boards based on Altera/Intel FPGAs. Its 4 Mbit flash tolerates the wide temperature swings of factory environments when specified in industrial temperature grade. Placed between the FPGA and the JTAG programming header, the EPC4Q100T enables factory-floor firmware updates via standard JTAG probes. Its 100-PQFP package (20 x 14 mm) is robust for through-hole-style mounting on industrial PCBs, and the 3.3 V core supply aligns with the rail already powering the FPGA I/O. For motor-control, PLC, and SCADA boards, the EPC4Q100T is a drop-in solution that survives field-replacement cycles in mature product families.

FPGA Prototyping Platform Bitstream Switching
The EPC4Q100T supports FPGA prototyping platforms where engineers switch between multiple bitstreams during hardware validation. The 4 Mbit flash holds one compressed bitstream while engineers iterate on RTL and reload via JTAG, and the 160 Mbps FPP configuration rate keeps reload time under a second for most Cyclone and APEX designs. Placed on a daughter card or interposer, the EPC4Q100T streams the bitstream into the target FPGA through a standard configuration header. Compared to using a separate microcontroller to load configuration, the EPC4Q100T requires no software stack and provides a known-good Altera/Intel reference design path, making it suitable for university and lab prototyping environments.
Được đề xuất
Legacy APEX FPGA Configuration Subsystem
The EPC4Q100T is a known-good configuration memory for APEX 20K and APEX II FPGAs in legacy military and aerospace subsystems. Its 4 Mbit density covers APEX EP20K100/EP20K200 bitstreams, and the 100-PQFP package provides the mechanical robustness required for through-hole mounting on avionics PCBs. Placed between the APEX device and the FPGA's configuration port, the EPC4Q100T streams the bitstream at power-up via the PS or FPP mode. Its 3.3 V core supply is compatible with APEX I/O rails. The EPC4Q100T is NRD for new designs but remains the validated choice for maintaining and repairing fielded APEX-based avionics and defense electronics where re-spinning the FPGA configuration subsystem is not feasible.

Ghi chú thiết kế
Place the EPC4Q100T as close as physically possible to the target FPGA's configuration port to minimize trace length on DCLK, nCONFIG, nSTATUS, CONF_DONE, and the 16-bit DQ bus. Per the Altera cf_52001 datasheet, configuration traces should be length-matched to within 1 inch and routed over a continuous ground plane to prevent signal-integrity issues during FPP mode at 10 MHz. Add 0.1 uF decoupling capacitors on each VCC pin and a bulk 10 uF tantalum near the device.
Do not confuse the EPC4Q100T (100-pin PQFP, 4 Mbit) with the EPC4QI100N (industrial temperature grade) or EPC16Q100 (16 Mbit, 100-pin PQFP) when sourcing - all three share the same footprint but differ in temperature grade or memory density. When migrating from a discrete boot PROM, ensure the JTAG chain order is correct: TCK/TMS/TDI/TDO must form a single daisy chain so the EPC4Q100T and the FPGA can be programmed in series. Do not apply 5 V to VCC - the EPC4Q100T core runs at 3.3 V; only legacy interface pins are 5 V tolerant.
Estimated: for the 100-pin PQFP at 20 x 14 mm, allow at least 25 x 19 mm of board real estate including keep-out zones for hand-soldering or inspection. Keep the EPC4Q100T away from switching power converters to avoid injecting noise into the configuration hand-shake signals. If the design uses Active Serial (AS) mode, route the serial data line away from the DQ[15:0] parallel bus to prevent crosstalk during power-up configuration.
Thông tin tuân thủ
RoHS/REACH compliance data not provided in Verified Web Data for EPC4Q100T. The Altera EPC family was originally released before RoHS mandates; later revisions may offer lead-free variants - check with the distributor for the specific date code. AEC-Q100 not applicable because this is a configuration memory, not a safety-critical automotive IC.
