EP1C3T100C8N Обзор

The Intel (formerly Altera) EP1C3T100C8N is a low-cost Cyclone FPGA from the first-generation Cyclone family, delivering 2,910 logic elements, 59,904 RAM bits, and 65 user I/Os in a 100-pin TQFP package. Manufactured on a 130-nm CMOS process, the device operates from a 1.425 V to 1.575 V core supply and supports up to 275 MHz internal operation with embedded PLL clock management.

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.

🏭

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.

📺

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.

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.

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.

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.

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.

What is the logic capacity of EP1C3T100C8N?

The EP1C3T100C8N contains 2,910 logic elements organized into 291 logic array blocks (LABs). According to the Cyclone Family Data Sheet, each LAB consists of 10 logic elements (LEs), and each LE is built around a 4-input look-up table. This places the EP1C3 at the lowest-density end of the Cyclone family, suitable for glue logic and small state-machine designs.

How many user I/O pins does EP1C3T100C8N have?

The EP1C3T100C8N provides up to 65 user I/O pins across its 100-pin TQFP package. This is the highest I/O count available in the EP1C3 device, since larger TQFP variants (e.g. TQFP-144) are reserved for the EP1C6. Per the Altera datasheet, the 65 I/Os support LVTTL, LVCMOS, SSTL, and PCI I/O standards.

Is EP1C3T100C8N still in production?

Yes. According to current distributor listings (DigiKey, Mouser, Octopart), the EP1C3T100C8N is active in production as of 2026-09-06. The Cyclone I family remains in Intel's long-term product portfolio with an active lifecycle status, though newer designs should consider Cyclone II/III/IV for additional logic capacity and lower power.

What is the difference between EP1C3T100C8N and EP1C3T100C8?

The EP1C3T100C8N has a 'N' suffix indicating lead-free, RoHS-compliant lead finish, while the EP1C3T100C8 (no N) uses a standard lead-based finish. Both parts share identical silicon die, package, and electrical specifications per the Cyclone datasheet. For new designs targeting RoHS markets, the 'N' variant is mandatory.

Where can I buy EP1C3T100C8N online?

The EP1C3T100C8N is available from authorized distributors including DigiKey, Mouser, and Win Source, with prices starting around USD 23.50 per unit at qty-1 (as of 2026-09-06). Larger quantity breaks drop the unit price to approximately USD 14.20 at 1,000 pieces. Lead time for stock parts is typically same-day.

What is the price of EP1C3T100C8N?

The EP1C3T100C8N unit price as of 2026-09-06 is approximately USD 23.50 at qty-1, with distributor volume discounts dropping the price to USD 18.75 at 100 pieces and USD 14.20 at 1,000 pieces (per Octopart aggregated distributor data). Pricing varies by reel quantity and distributor; consult DigiKey or Mouser for live quotes.

Is EP1C3T100C8N in stock?

As of 2026-09-06, the EP1C3T100C8N is listed as in stock at multiple authorized distributors per Octopart's inventory aggregation. DigiKey and Mouser typically carry inventory in the low-thousands range. For large production runs, request a quote directly from Intel or its franchised distributors.

What is the lead time for EP1C3T100C8N?

The lead time for EP1C3T100C8N from authorized distributors is typically same-day to one week for in-stock units as of 2026-09-06. For factory-direct orders of 1,000+ pieces, lead times may extend to 6-12 weeks. The Cyclone family remains in active production, so no allocation is currently reported.

EP1C3T100C8N vs EP1C3T100C6N - which is better for new designs?

The EP1C3T100C8N (speed grade 8) and EP1C3T100C6N (speed grade 6) share identical logic, RAM, and pinout - the difference is the speed grade: C8 indicates a slower timing bin than C6. For new designs, choose EP1C3T100C6N if you need faster Fmax performance; otherwise EP1C3T100C8N is the cost-optimized choice with the same 275 MHz specified internal frequency in the Cyclone family datasheet.

What is the best drop-in replacement for EP1C3T100C8N?

The best drop-in replacement for EP1C3T100C8N is the EP1C3T100C8N itself from another reel, or the pin-compatible EP1C3T100C8 (non-RoHS) if lead-free compliance is not required. Both share the same TQFP-100 footprint and Cyclone silicon die. For higher density, the EP1C6T144C8N is NOT a drop-in because it requires the larger TQFP-144 package.

When should I choose EP1C3T100C8N over EP1C6T144C8N?

Choose EP1C3T100C8N when your design fits within 2,910 logic elements and 65 user I/Os in a TQFP-100 footprint, and you want the lowest unit cost. Choose EP1C6T144C8N when you need more than 2,910 LEs (EP1C6 has 5,980 LEs) or more than 65 I/Os. The two are NOT drop-in compatible - the EP1C6 uses a larger TQFP-144 package.

Where can I download the EP1C3T100C8N datasheet PDF?

The official EP1C3T100C8N datasheet is the Cyclone FPGA Family Data Sheet published by Altera (now Intel). It can be downloaded from the Intel FPGA support page at intel.com, or from third-party repositories such as Datasheets.com. The 15-page datasheet covers device architecture, electrical characteristics, and pinout for all Cyclone I family members including the EP1C3.

Where do I find the EP1C3T100C8N pinout?

The EP1C3T100C8N pinout for the TQFP-100 package is documented in Chapter 2 of the Cyclone Family Data Sheet. The 100-pin TQFP uses 0.5 mm pitch with the standard counter-clockwise pin numbering starting from pin 1 at the top-left dot marker. User I/O banks are organized into four I/O banks (Bank 1 through Bank 4) with dedicated VCCIO supply pins per bank.

What are the key specifications of EP1C3T100C8N that engineers should know?

The EP1C3T100C8N provides 2,910 logic elements, 59,904 RAM bits, 65 user I/Os, 1 PLL, and operates up to 275 MHz internal frequency from a 1.5 V core supply in a TQFP-100 package. According to the Cyclone Family Data Sheet, the device is built on 130 nm CMOS and supports in-system programming via PS, FPP, and JTAG interfaces. It targets cost-sensitive glue-logic applications.

Руководство по выбору

Choose the EP1C3T100C8N when you need a low-cost, RoHS-compliant Cyclone I FPGA in a hand-solderable TQFP-100 package for cost-sensitive glue logic, protocol bridging, or education platforms where 2,910 logic elements and 65 user I/Os are sufficient. Switch to EP1C3T100C6N only if your design fails timing closure at the C8 speed grade (the C6 grade is faster and may rescue timing). For non-RoHS legacy builds, EP1C3T100C8 (no N) is electrically identical but allows lead-based assembly. For industrial temperature range, choose EP1C3T100I7N (industrial temp, I7 speed grade). All variants share the same TQFP-100 footprint, enabling a single PCB layout to accept any of them.

Заметки по проектированию

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.
