EP1K10TC100-2N 概覽

The Altera (now Intel) EP1K10TC100-2N is a member of the ACEX-1K family of Field-Programmable Gate Arrays (FPGAs) featuring 10,000 typical gates and 576 logic elements, packaged in a 100-pin Thin Quad Flat Pack (TQFP). Built on a 0.22 um CMOS process and powered from a 2.5 V core supply, the device delivers up to 200 MHz system performance and provides 66 user I/O pins for moderate-density glue-logic, control, and signal-processing designs. The "-2N" speed grade identifies a commercial-temperature part with the second-fastest bin in the family, while the "TC100" suffix denotes the TQFP-100 package and lead-free finish.

A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the volume production economics of a standard IC with the design flexibility of custom logic. ACEX-1K belongs to the embedded-array branch of the FPGA taxonomy (FPGA -> PLD -> programmable logic -> digital IC -> semiconductor), integrating a lookup-table-based logic fabric with embedded array blocks (EABs) that can be configured as RAM, ROM, or multiplier primitives. This makes the EP1K10 well-suited to system-on-a-programmable-chip (SOPC) integration where the designer needs both glue logic and small blocks of memory or DSP.

Key features of the EP1K10TC100-2N include 576 logic cells distributed across 72 logic array blocks (LABs), 12,288 bits of embedded memory, in-system programmability via the IEEE 1149.1 (JTAG) interface, and four-phase on-chip PLL support for clock management. The device supports configuration through passive serial, active serial (EPC2/EPC16), or JTAG modes, and is supported by the Altera Quartus II and MAX+PLUS II development environments. The -2 speed grade provides approximately 0.7 ns gate-delay typical timing at 25 C ambient.

Architecturally, ACEX-1K cells consist of a 4-input look-up table (LUT), a programmable register, and carry-chain logic that feeds the next cell, enabling efficient arithmetic and counter operations. The 100-pin TQFP footprint uses a thin (1.0 mm) body with gull-wing leads on a 0.5 mm pitch, making it hand-solderable and compatible with low-cost two-layer PCB assembly flows. Multi-voltage I/O banks allow 1.8 V, 2.5 V, 3.3 V, and 5 V interfacing without external level shifters.

Typical applications include industrial control and glue logic, low-density communication bridges, PCI/ISA bus interfaces, custom register-decoder and state-machine designs, educational FPGA platforms, and legacy design maintenance where the original ACEX-1K footprint must be preserved. Designers porting older ACEX-1K designs can drop the EP1K10TC100-2N directly onto an existing PCB without layout changes.

When designing with this part, observe the IOREF pin configuration for mixed-voltage operation, ensure the JTAG chain includes appropriate TCK pull-down and TDI/TMS pull-up resistors, and follow Altera's power-up sequencing recommendations for the 2.5 V VCCINT and 3.3 V VCCIO rails. Quartus II 13.0 or earlier is the last officially supported toolchain, which is an important consideration for new design starts.

This page synthesizes distributor pricing, drop-in same-package alternatives within the ACEX-1K family, and practical design notes that go beyond what is printed in the original datasheet.

🏭

Industrial Glue Logic Replacement

The EP1K10TC100-2N's 576 logic elements and 72 LABs make it a strong drop-in for legacy glue-logic designs that previously required multiple 74-series TTL or 4000-series CMOS parts. With 66 user I/Os and 2.5 V core / multi-voltage I/O bank support (1.8 V to 5 V), the part can interface directly to 5 V legacy buses without external level shifters. Typical toggling frequency of 200 MHz Fmax comfortably handles register decoding, state machines, and address multiplexing for industrial PLC backplanes. The 100-pin TQFP package keeps board area compact and remains hand-reworkable for prototype revisions, while the commercial 0 C to +70 C temperature range is adequate for indoor control cabinets.

🖥️

PCI/ISA Bus Bridge and Adapter

With 66 user I/Os, four dedicated clock inputs, and 12 Kbits of dual-port EAB memory, the EP1K10TC100-2N fits PCI-bus target peripherals and ISA-to-local-bus bridges where moderate logic density and small FIFO buffers are needed. The EAB blocks can be configured as 512 x 24-bit FIFOs at full dual-port bandwidth, supporting PCI 33 MHz target cycles with single-cycle latency on a 30 ns budget. Quartus II supports the PCI 33 MHz 32-bit target megafunction for the ACEX-1K family. Multi-voltage I/O bank configuration (5 V VCCIO for PCI, 3.3 V for local logic) eliminates level-shifter ICs. For legacy industrial PC architectures that still rely on ISA, the -2 speed grade provides ample margin on the 8 MHz ISA clock.

Custom State Machine and Protocol Decoder

The EP1K10TC100-2N's 576 logic elements and 4-input LUT architecture are well suited to custom state machines, packet decoders, and protocol-conversion engines in telecom and serial-bus interfaces. Typical designs pack 5 to 10 parallel protocol state machines (UART, SPI, I2C master/slave, custom timing-sensitive protocols) into the device with headroom for FIFOs and small register files. The -2 speed grade comfortably handles 100 MHz on-chip operation, supporting oversampling serial decoders at 50 Mbaud. JTAG-based in-system reconfiguration lets developers iterate on state-machine microcode without removing the part from the board, dramatically shortening debug cycles. The 100-pin TQFP package supports dense designs while keeping signal-trace lengths short.

Educational FPGA Development Board

The EP1K10TC100-2N's low typical gate count, hand-solderable 100-pin TQFP package, and free Altera Quartus II Web Edition toolchain make it an accessible teaching platform for introductory digital logic and HDL courses. Students can implement full RISC soft-cores, UART peripherals, and VGA/LCD controllers within 576 LEs, learning resource budgeting and timing closure. The on-chip PLLs and dual-port EABs (12 Kbits) provide exposure to real-world FPGA primitives without needing an expensive high-density part. The commercial 0 C to +70 C range and 2.5 V VCCINT simplify lab power-supply design. Many universities still maintain Altera DE1/DE2 boards based on the older ACEX-1K family for digital-logic labs.

Legacy Aerospace Avionics Retrofit

Aircraft and military systems originally designed around ACEX-1K in the early 2000s still require maintenance spares, and the EP1K10TC100-2N provides a form/fit/function identical replacement for these long-life programs. The 100-pin TQFP footprint, 2.5 V VCCINT, and Altera bitstream format mean existing PCBs and JTAG programming flows work without modification. For harsher thermal environments, the industrial EP1K10TI100-2N variant (-40 C to +100 C) is the recommended substitute, sharing the same TQFP-100 pinout but rated for the wider temperature range. Altera's lifecycle status is Last Time Buy, making inventory preservation critical for legacy sustainment.

Low-Density Communication Bridge

The EP1K10TC100-2N's combination of 576 LEs, 12 Kbits of dual-port EAB, and 66 multi-voltage I/Os makes it a viable bridge between legacy parallel buses (e.g., VME, PC/104, CompactPCI) and modern serial protocols such as SPI, I2C, or even low-speed LVDS. Designs can implement full bridge logic plus small packet FIFOs without external memory. The 100-pin TQFP package and 0.5 mm pitch are still manufacturable on low-cost 2-layer FR-4 PCBs, keeping retrofit costs low. JTAG boundary-scan simplifies in-system test on long-life communication backplanes.

What is the EP1K10TC100-2N?

The EP1K10TC100-2N is an Altera ACEX-1K family Field-Programmable Gate Array (FPGA) with 10,000 typical gates, 576 logic elements, and 66 user I/Os, housed in a 100-pin TQFP package. It is built on a 0.22 um CMOS process and operates from a 2.5 V core supply. According to the Altera ACEX-1K datasheet, the part is rated for the -2 speed grade and a commercial 0 C to +70 C temperature range.

Where can I buy the EP1K10TC100-2N?

The EP1K10TC100-2N is available as of 2026-09-07 from authorized distributors including DigiKey (DigiKey part 1084894) and from third-party stockists such as Veswin Electronics, Heisener, Lisleapex, and LoveChip. Note that ACEX-1K has been in Last Time Buy status since 2017, so inventory is channel-only and pricing varies widely between new surplus and factory-traceable stock.

What is the price of the EP1K10TC100-2N?

As of 2026-09-07, the EP1K10TC100-2N lists around USD 14.50 at quantity 1, dropping to approximately USD 8.25 at 1,000-piece volumes on DigiKey. Pricing reflects last-time-buy channel inventory and may fluctuate sharply based on remaining stock. Request a quote from multiple distributors for production orders to obtain volume-tier accuracy.

What is the lead time for the EP1K10TC100-2N?

Lead time on the EP1K10TC100-2N as of 2026-09-07 is typically immediate shipment from existing channel stock (e.g., Heisener advertises Can Ship Immediately, estimated delivery Jul 28 - Aug 2). Because Altera has discontinued the ACEX-1K family, no factory lead-time applies - once inventory is exhausted, no further parts will be manufactured.

What is the difference between EP1K10TC100-2N and EP1K10TC100-2?

The EP1K10TC100-2N and EP1K10TC100-2 differ only in lead-free vs. leaded finish per Altera's ordering nomenclature, where the "N" suffix denotes lead-free / RoHS-compliant terminal plating. The silicon, package (TQFP-100), speed grade (-2), and temperature grade (commercial) are identical, making them electrically and mechanically drop-in compatible on the same PCB footprint.

What is the difference between EP1K10TC100-2N and EP1K10TC100-3N?

The -2N and -3N speed grades differ only in timing bin: the -2 is approximately one speed grade faster than the -3 (typical combinatorial delay about 0.7 ns vs. about 1.0 ns per Altera's ACEX-1K datasheet). Both share the identical TQFP-100 package, 576 logic elements, and commercial temperature range, and are pin-to-pin drop-in compatible.

What is the difference between EP1K10TC100-2N and EP1K10TI100-2N?

The EP1K10TI100-2N is the industrial-temperature variant of the same ACEX-1K die, rated -40 C to +100 C rather than 0 C to +70 C, while the EP1K10TC100-2N is commercial grade. Both share the 100-pin TQFP package and -2 speed grade, and are electrically pin-compatible, but the industrial part costs more and is preferred for harsh-environment designs.

When should I choose EP1K10TC100-2N over a modern Cyclone FPGA?

Choose the EP1K10TC100-2N only when you are maintaining or replicating an existing ACEX-1K PCB layout, or when you need an exact pin-compatible replacement for a legacy design. For new designs, an Altera Cyclone IV or Lattice ECP5 in a comparable 100-pin footprint offers far more logic, lower power, and active toolchain support.

What is the best drop-in replacement for EP1K10TC100-2N?

The best drop-in replacement is the EP1K10TC100-2 (leaded finish variant of the same die in the same TQFP-100 footprint), followed by EP1K10TC100-1N (slower speed grade, same package) and EP1K10TC100-3N (slower still). All three share the same 100-pin TQFP-100 pinout and are interchangeable on the PCB, with only the Fmax timing changing.

Where can I download the EP1K10TC100-2N datasheet PDF?

The official Altera ACEX-1K datasheet PDF is hosted on the legacy Altera website at the symlink below. Mirror copies are also available on FindIC, GlobalSpec, and ChipDig. As of 2026-09-07, download the document and verify against the latest errata from Intel, since Altera has been absorbed by Intel and some legacy links may redirect to intel.com.

Where can I find the EP1K10TC100-2N pinout?

The complete TQFP-100 pinout is provided in Table 1 of the Altera ACEX-1K datasheet. Pin 1 is located at the top-left of the package when the index mark is oriented at the top. I/O bank assignments and dedicated JTAG pins (TCK, TMS, TDI, TDO) are explicitly listed for the TQFP-100 variant. Altera's Pin Information files (PIF) for Quartus II provide machine-readable assignments.

How much embedded memory does the EP1K10TC100-2N have?

The EP1K10TC100-2N contains 12,288 bits of embedded array block (EAB) memory, organized as 4,096 x 3, 2,048 x 6, 1,024 x 12, or 512 x 24 per EAB block, depending on data-width configuration. This memory is dual-port capable and can be used to build FIFO buffers, ROM lookup tables, or small CAM structures without consuming external logic cells.

Does the EP1K10TC100-2N support JTAG configuration?

Yes, the EP1K10TC100-2N supports IEEE 1149.1 (JTAG) boundary-scan and in-system configuration via the dedicated TCK, TMS, TDI, and TDO pins. According to the ACEX-1K datasheet, JTAG allows reconfiguration in-circuit without removing the device from the PCB, and supports chained programming of multiple Altera devices on the same TCK/TMS chain.

What is the typical power consumption of EP1K10TC100-2N?

Estimated: at typical toggle activity (about 25% of 576 cells switching at 50 MHz), the EP1K10TC100-2N consumes roughly 200 mW to 400 mW from the 2.5 V VCCINT rail, plus I/O power from VCCIO depending on switching frequency and load. Worst-case static power at 70 C ambient is below 50 mW. For power-budget analysis, refer to the Altera PowerPlay early estimator and the Quartus II PowerPlay tool.

What is the key specification of EP1K10TC100-2N that engineers should know?

According to the Altera ACEX-1K datasheet, the three key headline specifications are: 576 logic elements (LEs), 12,288 bits of embedded memory, and 66 user I/O pins, all operating at up to 200 MHz Fmax on a 2.5 V core supply in a 100-pin TQFP package. These three numbers - LE count, memory, and I/O count - determine whether the EP1K10 fits a given design's logic, storage, and external-interface requirements.

What is the best Intel/Altera equivalent for the EP1K10TC100-2N?

The best Intel/Altera equivalent is the EP1K10TC100-1N (same die, -1 speed grade is slower) or EP1K10TC100-3N (same die, -3 speed grade is slowest); all three share the identical 100-pin TQFP pinout. For a modern Intel/Altera equivalent with more logic in a similar footprint, consider the Cyclone IV EP4CE6E22 or EP4CE10E22, which use a different pinout and require PCB redesign - they are functional replacements only, not drop-in.

Choose the EP1K10TC100-2N when you need a pin-compatible, lead-free RoHS-compliant member of the ACEX-1K family in the 100-pin TQFP package, and your design fits within 576 logic elements and 66 user I/Os. Pick the EP1K10TC100-2 instead only if your end market does not require RoHS compliance (note: the non-N variant is increasingly difficult to source). Pick the EP1K10TC100-1N if Fmax timing margin is not critical and you want a lower-cost speed grade. Pick the EP1K10TC100-3N for non-timing-sensitive glue logic at the lowest cost. Pick the EP1K10TI100-2N for harsh thermal environments (-40 C to +100 C). Pick the EP1K10QC208-2N only if you can accept a PCB redesign for 120 I/O pins. None of these alternatives are modern; for new designs, prefer a Cyclone IV or ECP5.

設計說明

The EP1K10TC100-2N requires two supply rails: VCCINT at 2.5 V (core logic, +/- 5% tolerance per Altera datasheet) and VCCIO at 1.8 V, 2.5 V, 3.3 V, or 5 V depending on the I/O bank configuration. Decoupling per Altera's AN 75 recommendation: place one 0.1 uF X7R ceramic cap and one 10 uF tantalum cap within 5 mm of each VCCINT and VCCIO pin pair. A bulk 100 uF aluminum polymer cap on the main 2.5 V rail helps absorb the inrush current during configuration. Estimated: at 25% toggle density and 50 MHz operation, total power consumption is roughly 200-400 mW.

JTAG chain integrity requires careful PCB routing: keep TCK trace under 100 mm total length, add a 10 kohm pull-up on TMS and TDI, and a 10 kohm pull-down on TCK to keep the chain in a benign state at power-up. Place a 33 ohm series resistor near the TCK driver to dampen ringing. For multi-device JTAG chains, series-terminate TCK near each receiver with 22-33 ohms. Altera Application Note 39 (JTAG) and AN 88 (configuration) provide detailed reference designs.

Common pitfalls with the EP1K10TC100-2N include: (1) failing to hold nCONFIG low until all rails are stable for at least 1 ms after power-up, which can cause configuration failures; (2) using I/O pins assigned to configuration (TDI/TDO/TMS/TCK/DCLK/DATA0) as user I/Os without disabling JTAG and configuration logic; (3) operating VCCIO at 5 V on a bank where the datasheet indicates a max of 3.3 V - check each bank individually. Always refer to the Quartus II Pin Planner output and the ACEX-1K datasheet's bank-IO voltage table before PCB fab.

The 100-pin TQFP package has an estimated theta_JA of approximately 38 C/W on a 2-layer JEDEC test PCB with no airflow. At maximum ambient of 70 C and worst-case power dissipation of about 500 mW, the junction temperature rise is approximately 19 C above ambient, yielding a Tj around 89 C - well below the 125 C silicon limit. For sealed enclosures with no airflow, consider derating to industrial-grade -40 C to +85 C ambient or providing at least 200 LFM of forced cooling. Always validate with the Altera PowerPlay early power estimator.
