MPN: EP1C3T100C8N ✓ Hoạt độngEP1C3T100C8N Tóm tắt
What is a Cyclone FPGA? The Cyclone family is Intel FPGA's low-cost, high-volume programmable logic series, positioned below the Stratix high-performance family in the FPGA hierarchy: FPGA -> SRAM-based programmable logic -> programmable logic device (PLD) -> digital logic IC. Cyclone parts target glue-logic, bus bridging, and DSP pre/post-processing in cost-sensitive designs where the high-end Stratix I/O bandwidth and transceivers are unnecessary. The 'N' suffix indicates lead-free, RoHS-compliant packaging.
Key features include 2,910 logic elements organized into 291 logic array blocks (LABs), 13 embedded 4-Kbit M4K RAM blocks totaling ~60 Kbits, one PLL per device with up to four output taps, support for LVDS, LVTTL, LVCMOS, SSTL, and PCI I/O standards, and in-system programmability through the passive serial (PS), fast passive parallel (FPP), or JTAG configuration interfaces. The TQFP-100 footprint simplifies PCB layout for low-density designs.
Architecturally, the EP1C3T100C8N uses a 4-input look-up table (LUT) based logic element with embedded carry chains for arithmetic and dedicated M4K memory blocks. The single PLL provides clock multiplication, division, and phase shift for up to three or four output clocks, sufficient for basic DDR memory interfaces and standard video/serializer timing.
Typical applications include low-cost video processing, industrial control logic, consumer electronics glue logic, education and prototyping platforms, and serial protocol bridging (UART, SPI, I2C). The part is widely used in legacy designs that pre-date Cyclone II/III/IV migration; many production designs still rely on the EP1C3 due to its low unit cost and long-term Intel supply commitment.
Design consideration: The EP1C3 uses a 1.5 V core and requires a separate configuration memory or download cable for in-system programming. Plan for the 1.5 V regulator (e.g., a small LDO) and a JTAG header on the PCB. Signal integrity at 100+ MHz requires impedance-controlled traces on the LVDS pairs.

Ứng dụng tiêu biểu
EP1C3T100C8N phù hợp cho 6 Áp dụngs: Industrial Control Logic, Video Processing Front-End, Consumer Electronics Glue Logic, Education and Prototyping Platforms, Serial Protocol Bridging, Legacy System Sustainment.
Industrial Control Logic
The EP1C3T100C8N's 2,910 logic elements and 65 user I/Os make it well-suited for industrial control boards where multiple sensor inputs and actuator outputs must be coordinated with deterministic timing. The single PLL generates stable clocks for motor-control PWM modules, and the 130 nm CMOS architecture tolerates the wide temperature swings common in factory-floor enclosures when paired with the I-temp variant. Engineers value the TQFP-100 footprint for hand-solderable prototypes and field-replaceable designs.
Được đề xuất
Video Processing Front-End
The 13 embedded M4K RAM blocks (totaling ~60 Kbits) and 1 PLL on the EP1C3T100C8N provide enough on-chip buffering and clock synthesis for cost-sensitive video front-ends such as line buffers, color-space converters, and overlay mixers. LVTTL/LVCMOS I/O standards support parallel digital video interfaces (BT.656, BT.601) at standard definition, while the 275 MHz internal operation comfortably handles pixel-clock domains. The TQFP-100 footprint is preferred over BGA for hand-rework in low-volume broadcast equipment.
Được đề xuất
Consumer Electronics Glue Logic
Consumer devices that need a small amount of custom logic - protocol bridging, format conversion, LED driving - frequently use the EP1C3T100C8N because of its sub-$15 unit price at volume and Intel's long-term supply commitment. The 100-pin TQFP mounts on standard 4-layer FR-4 with no BGA rework equipment required, keeping manufacturing cost low for high-volume SKUs. The 4-input LUT architecture easily implements UART/SPI/I2C bridges and small state machines.
Được đề xuất
Education and Prototyping Platforms
Universities and FPGA-training labs use the EP1C3T100C8N as a low-risk teaching platform because the TQFP-100 package is hand-solderable on breakout boards, the Quartus II toolchain is free, and the device has abundant reference designs online. The 2,910 LE capacity is enough to teach RTL coding, finite state machines, basic DSP, and soft-core CPU implementations (e.g. Nios II) without overwhelming students with device complexity. Many Altera/Intel DE-series boards use Cyclone parts for the same reasons.
Được đề xuất
Serial Protocol Bridging
The EP1C3T100C8N is widely deployed as a bridge between incompatible serial interfaces - UART-to-SPI, I2C-to-SMBus, RS-232-to-USB, or proprietary sensor protocols. The 65 user I/Os allow multiple bus controllers to be implemented in parallel, and the 1 PLL provides clock synthesis for any baud rate or SPI clock frequency needed. The Cyclone architecture's deterministic timing avoids the latency jitter that microcontroller-based bridges introduce.
Được đề xuất
Legacy System Sustainment
Long-lifecycle industrial and aerospace systems designed in the early 2000s often depend on the EP1C3T100C8N and must continue production for 10-20 years. Intel's active support for the Cyclone family, combined with the part's stable silicon and TQFP-100 footprint, makes field replacements straightforward without board redesign. Legacy firmware bitstreams remain compatible with newer Quartus programmer versions, simplifying obsolescence management.

Ghi chú thiết kế
The EP1C3T100C8N requires a 1.5 V VCCINT supply (1.425 V to 1.575 V) capable of sourcing up to ~300 mA during configuration plus dynamic current proportional to switching activity. Use a low-noise LDO such as the TI TPS7A4533 or a switching regulator followed by an LDO for noise-sensitive analog rails. Decouple each VCCINT pin with a 0.1 uF X7R ceramic cap plus a 10 uF bulk cap on the same PCB layer. I/O banks (VCCIO1 through VCCIO4) can run at 1.5 V, 1.8 V, 2.5 V, or 3.3 V independently - tie each unused VCCIO bank to a valid rail, do NOT leave it floating.
Route the TQFP-100 with 0.5 mm pitch using 4 mil traces and 4 mil spaces on a 4-layer FR-4 stackup. Place all configuration components (EPCS serial flash, JTAG header, nCONFIG/nSTATUS pull-ups) within 25 mm of the FPGA. The JTAG chain should include a 10 kohm pull-up on TCK, TMS, and TDI. Avoid routing LVDS signals on the top layer over the FPGA's lead frame; use inner stripline layers with continuous ground reference for the 275 MHz+ signals.
Common pitfalls: (1) leaving VCCIO banks floating will cause I/O behavior to be undefined - always power all four banks even if unused; (2) using the wrong configuration mode - the EP1C3 supports PS (passive serial, most common), FPP (fast passive parallel), and JTAG, but the MSEL pins must be tied to the correct logic levels for the chosen mode; (3) forgetting that the EP1C3 does not have dedicated DDR memory controllers - any DDR interface must be built with user logic and the M4K RAM blocks. Verify pin assignments in the Quartus Pin Planner before PCB fabrication.
Thông tin tuân thủ
