EP1C3T100CN8 - Cyclone FPGA 3K LEs 100-TQFP | Altera (Intel PSG)
MPN: EP1C3T100CN8 ✗ Cuối đờiEP1C3T100CN8 Tóm tắt
What is an FPGA? An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks, configurable interconnect, and programmable I/O cells that engineers can configure after manufacturing to implement custom digital circuits. FPGAs occupy the tier between CPLDs (smaller, non-volatile) and ASICs (custom, high-NRE), making them ideal for prototyping, low-volume production, and applications requiring hardware-level parallelism. The Altera Cyclone family sits in the low-cost, high-volume segment, optimized for price-sensitive designs.
Key features of the EP1C3T100CN8 include two PLLs for clock management, dedicated 18×18 multipliers (originally marketed under the DSP block branding), and support for LVTTL, LVCMOS, SSTL-2, and SSTL-3 I/O standards. The device supports configuration via passive serial (PS), JTAG, and Altera-specific configuration schemes, and integrates Altera's Quartus II design suite for synthesis, place-and-route, and timing closure.
Technically, the Cyclone architecture pairs 4-input look-up-tables (LUTs) with embedded memory blocks (M4K blocks) and distributed multiplier resources. The 100-pin TQFP package provides moderate I/O count with surface-mount manufacturability but limits total pin count compared to BGA-packaged Cyclone variants, so it is typically chosen for I/O-light glue logic, control planes, and industrial interface bridging.
Typical applications include industrial control and bridging, low-cost video processing front-ends, peripheral expansion in embedded systems, glue logic replacing discrete MSI parts, and education/hobby platforms. Designers choose the EP1C3T100CN8 over larger Cyclone devices when logic requirements fit within 3K LEs and the TQFP package simplifies assembly.
Design consideration: this part is NRND/EOL per Intel PSG's Cyclone legacy notice — verify lifetime-buy windows and consider modern Cyclone IV/V/10 equivalents for new designs. Always validate timing closure at the chosen speed grade against target fMAX.
This page synthesizes distributor inventory, drop-in same-package alternatives, and practical design context that goes beyond the manufacturer datasheet front matter, helping engineers source and apply the EP1C3T100CN8 quickly.

Ứng dụng tiêu biểu
EP1C3T100CN8 phù hợp cho 6 Áp dụngs: Industrial Control and Bridging, Embedded Glue Logic Replacement, Low-Cost Video Processing Front-End, Peripheral Expansion for Embedded Systems, Education, Hobby, and Prototyping Platforms, Legacy Interface Replication and Long-Life Support.
Industrial Control and Bridging
The EP1C3T100CN8's 2,910 logic elements and 65 user I/O pins make it well suited for industrial control bridging — translating between legacy parallel buses (PC/104, ISA), industrial fieldbuses, and modern serial interfaces such as SPI, I2C, and UART. Two on-chip PLLs generate independent clock domains for motor control PWM and encoder feedback. The 100-pin TQFP simplifies hand-rework for low-volume industrial retrofits where BGA rework would be impractical.
Được đề xuất
Embedded Glue Logic Replacement
Designers migrating from discrete 74-series MSI logic or small CPLDs to a single programmable device use the EP1C3T100CN8 to consolidate address decoding, bus arbitration, and timing logic onto one Cyclone FPGA. With 59,904 RAM bits of M4K block memory and 2,910 LEs, the device replaces dozens of discrete packages while improving timing margins. Quartus II integration lets engineers reuse legacy schematics as HDL through schematic-capture import.
Được đề xuất
Low-Cost Video Processing Front-End
For low-cost video front-ends (VGA capture, LCD controller, simple image preprocessing), the EP1C3T100CN8 provides enough logic to implement timing controllers, simple color-space converters, and frame-buffer arbitration for a 640×480 stream at modest frame rates. The TQFP-100 footprint exposes sufficient I/O for 16-bit digital video plus auxiliary control signals. Use the on-chip PLLs to synthesize pixel clocks from a single reference oscillator.
Được đề xuất
Peripheral Expansion for Embedded Systems
Embedded CPU boards (PC/104, VME, CompactPCI) often need extra I/O ports, custom interrupt controllers, or specialised interfaces that the host SoC cannot natively provide. The EP1C3T100CN8 in TQFP-100 sits easily alongside such CPUs as a peripheral-expansion co-processor, attaching via the host's memory bus or local-bus pins. Its two PLLs let the Cyclone derive peripheral clocks independently from the host system clock.
Được đề xuất
Education, Hobby, and Prototyping Platforms
The Cyclone I EP1C3T100CN8 is widely adopted in university digital-logic labs, FPGA training boards, and maker-class development kits because of its low cost, breadboard-friendly TQFP-100 breakout boards, and rich Quartus II Web Edition toolchain. Students implement UART controllers, simple CPUs, VGA drivers, and state machines against the 2,910-LE fabric. The commercial 0–85 °C range is sufficient for lab environments, and the device's SRAM-based fabric supports unlimited ISP cycles for iterative learning.
Được đề xuất
Legacy Interface Replication and Long-Life Support
Many long-lifecycle industrial and aerospace programs still need to build replacement boards for installed equipment that originally shipped with Cyclone I designs. The EP1C3T100CN8 preserves exact bitstream compatibility with Quartus II designs from the original deployment era, avoiding forced firmware rewrites. Its 100-TQFP footprint and Cyclone I JTAG scheme match legacy PCB test fixtures, minimising requalification effort for spare-part production.

Ghi chú thiết kế
The EP1C3T100CN8 requires a clean 1.5 V core supply; pair it with an LDO such as a TLV1117-1.5V or a switching regulator with sufficient filtering. Estimated quiescent core current for an unconfigured Cyclone I device is approximately 50–100 mA depending on usage rate, so budget at least 250 mA on the 1.5 V rail. Decouple each VCCINT pin with a 0.1 µF X7R ceramic placed within 5 mm of the package pin.
TQFP-100 land pattern is straightforward but thermal dissipation benefits from a ground plane under the device. Estimated: at maximum junction-to-ambient thermal resistance of approximately 30 °C/W and a typical 0.5 W core dissipation, the junction rises ~15 °C above ambient. Provide at least 1 oz copper pour on all four inner layers and stitch the ground pin (31, 51, 72) returns directly to the ground plane.
Do not omit the EPCS serial configuration memory on a stand-alone board — the Cyclone I SRAM fabric loses its configuration on power-down. Tie nCONFIG high through a 1–10 kΩ pull-up, leave MSEL pins at the correct logic level for AS or PS mode (typically MSEL[1:0] = 00 for passive serial), and provide a 10 kΩ pull-up on nSTATUS and CONF_DONE. Forgetting to de-bounce the nCONFIG push-button is a frequent cause of intermittent boot failures in field returns.
