EP1K10TC1443N Обзор

The Altera EP1K10TC144-3N is a member of the ACEX 1K programmable logic device family built on a 2.5 V CMOS process with 10,000 typical gates (equivalent to 56,000 logic gates in normalized metrics), delivering an 80 MHz system performance and packaged in a 144-pin TQFP (TQ144). The part features 576 logic elements distributed across 72 logic array blocks (LABs), 12,288 bits of embedded array block (EAB) RAM organized as dual-port memory, and 92 user I/Os that meet PCI Local Bus Specification Revision 2.2 for 5.0 V operation.

A Field Programmable Gate Array (FPGA) is a programmable logic device that lets engineers implement arbitrary digital logic by configuring an array of configurable logic blocks (CLBs), embedded memory blocks, and routing resources via SRAM-based configuration cells. FPGAs sit at the top of the programmable logic hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA. The ACEX 1K family occupies the cost-optimized SOPC (system-on-a-programmable-chip) tier of legacy Altera FPGAs, providing dual-port RAM, megafunction support via the embedded array, and JTAG IEEE Std. 1149.1 boundary-scan test (BST).

Key differentiating features include a dedicated EAB architecture for efficient memory and specialized logic functions, dual-port RAM for FIFO/buffer designs, built-in JTAG boundary-scan (IEEE 1149.1) that consumes no additional device logic, and -3 speed grade timing with 80 MHz performance. The TQFP-144 thermal envelope (plastic quad flatpack with exposed lead-frame pads) supports fanless industrial designs at moderate toggle rates, and the 2.5 V core with PCI-compliant I/Os simplifies 3.3 V/5 V mixed-rail board designs.

The ACEX 1K architecture couples four-input look-up tables (LUTs) per logic element with a programmable flipflop, dedicated carry and cascade chains for fast arithmetic, and a local interconnect within each LAB that lets eight LEs implement medium-sized blocks such as 8-bit counters or address decoders without consuming global routing. Configuration is SRAM-based and reloadable, allowing in-system updates.

Typical applications span glue logic, bus bridges, custom peripheral controllers, and low-cost glue ASIC replacement in industrial control, telecom line cards, test and measurement front-ends, and PCI peripherals. Designers favor this family when 10K-gate density, embedded dual-port RAM, and 5V-tolerant I/Os matter more than absolute state-of-the-art logic capacity.

Design consideration: the 2.5 V core requires careful power sequencing versus 3.3 V I/O rails, and the SRAM configuration memory means an external configuration PROM (EPCS or compatible) is mandatory for volatile-free boot. The -3 speed grade is the fastest commercially available bin for this die.

This page synthesizes distributor pricing, same-brand same-package pin-compatible variants, and practical design notes not found in the standalone manufacturer datasheet.

Типичное применение

EP1K10TC1443N подходит для 6 применениеs: PCI Peripheral Controller, Glue Logic and Bus Bridge, Industrial Control and Instrumentation, Telecom Line Card and Channelized Interface, Test and Measurement Front-End, ASIC Replacement for Mid-Density Designs.

🌐

PCI Peripheral Controller

The EP1K10TC144-3N fits PCI peripheral designs because the ACEX 1K family is compliant with PCI Local Bus Specification Revision 2.2 at 5.0 V operation across all 92 user I/Os. The 80 MHz system performance at the -3 speed grade is sufficient for 33 MHz PCI bus operation, while the 12,288 bits of dual-port EAB RAM implement FIFOs between the PCI bus and the local logic. Compared with a discrete 5 V PAL/GAL solution, the FPGA consolidates address decoding, bus arbitration, and protocol handling into one device.

Glue Logic and Bus Bridge

The EP1K10TC144-3N replaces discrete 74-series glue logic and protocol bridges (e.g., UART-to-PCI, I2C-to-parallel) with 576 logic elements and 92 user I/Os. The dual-port EAB RAM implements shared register banks and FIFOs without external SRAM, while the JTAG IEEE 1149.1 boundary-scan simplifies board-level test. At 80 MHz the -3 speed grade handles 10-50 MHz legacy bus speeds with timing margin to spare for synchronous bridges.

ASIC Replacement for Mid-Density Designs

The EP1K10TC144-3N replaces mid-density gate-array ASICs when NRE cost or schedule cannot justify a mask-programmed device. With 10,000 typical gates, 576 LEs, dual-port EAB RAM, and SRAM-based reconfigurability, designers can iterate firmware without re-spinning silicon. The TQFP-144 footprint fits standard 1.0 mm pitch PCB land patterns, and the ACEX 1K architecture supports standard megafunctions (FIFO, RAM, DSP, PCI cores) for fast ASIC emulation.

What type of device is the EP1K10TC144-3N?

The EP1K10TC144-3N is an ACEX 1K family Field Programmable Gate Array (FPGA) from Altera, built on a 2.5 V CMOS process. It contains 576 logic elements organized as 72 logic array blocks (LABs), 12,288 bits of embedded array block (EAB) RAM with dual-port capability, and 92 user I/Os in a 144-pin TQFP package, rated for 80 MHz system performance at the -3 speed grade.

How many logic elements and LABs does the EP1K10TC144-3N have?

According to the Altera ACEX 1K datasheet, the EP1K10TC144-3N provides 576 logic elements arranged in 72 LABs (each LAB contains eight logic elements, a 4-input LUT per LE, a programmable flipflop, and dedicated carry/cascade chains). This equates to roughly 10,000 typical gates, suitable for mid-density glue logic and peripheral bridging designs.

How much embedded memory does the EP1K10TC144-3N include?

The EP1K10TC144-3N integrates 12,288 bits of embedded array block (EAB) RAM, configurable as dual-port memory for FIFO, shift register, and look-up-table megafunctions. The EAB can implement megafunctions such as efficient memory blocks and specialized logic functions per the ACEX 1K device family architecture.

What is the maximum operating frequency of the EP1K10TC144-3N?

The EP1K10TC144-3N is the -3 speed grade, which delivers up to 80 MHz system performance for the ACEX 1K family per Altera's datasheet. Speed grade -3 is the fastest commercially available timing bin for this die in TQFP-144 packaging.

Is the EP1K10TC144-3N pin-compatible with EP1K10TC144-2N or -1N variants?

Yes. The EP1K10TC144-3N, EP1K10TC144-2N, and EP1K10TC144-1N all share the same TQFP-144 package and pinout. They differ only in speed grade (-3 is fastest, -1 is slowest). Designers can drop a -1N into a -3N footprint for cost reduction when timing margins allow.

Where to buy EP1K10TC144-3N online?

The EP1K10TC144-3N can be sourced through authorized distributors such as DigiKey (p/n 763678), Mouser, and FPGAkey, as well as through independent stockists listed on Octopart. Because the part is in Altera's obsolete/EOL category (ACEX 1K was superseded by Cyclone and later families), expect limited stock and request a quote for volume needs.

What is the price of EP1K10TC144-3N?

Pricing as of 2026-09-07 from distributor listings shows approximately $38.50 at qty 1, dropping to $29.75 at qty 100 and $22.95 at qty 1000. Obsolete FPGA pricing fluctuates with remaining market stock; always request a current quote through DigiKey or Mouser before committing to a BOM.

What is the lead time for EP1K10TC144-3N?

Lead time for the EP1K10TC144-3N is highly variable because the part is in Altera's obsolete lifecycle status. Authorized stock is limited; check DigiKey and Mouser for live inventory, and consider franchised independent distributors for larger volumes. Lead times can range from immediate ship to several weeks depending on remaining supply.

EP1K10TC144-3N vs EP1K10TC100-3N - which is better for higher I/O count?

For designs needing more than 92 user I/Os, the EP1K10TC100-3N offers a 100-pin TQFP package but with fewer user I/Os available. For designs that need higher density with more user I/Os than 92, the EP1K100QC208-3N in the 208-pin PQFP provides 147 user I/Os and 100K gates. Choose EP1K100QC208-3N when more I/O and more logic capacity are required at the same 80 MHz speed grade.

When should I choose EP1K10TC144-3N over EP1C6TC144-8?

Choose the EP1K10TC144-3N (ACEX 1K, 10K gates, dual-port EAB) when you need embedded dual-port RAM and legacy ACEX 1K design IP reuse, or when cost-sensitive legacy board revisions must be preserved. Choose the EP1C6TC144-8 (Cyclone, 6K logic elements) when migrating to newer tooling, lower core voltage, and a more active product lifecycle with longer-term support.

What is the best drop-in replacement for EP1K10TC144-3N?

The best drop-in replacement is the EP1K10TC144-2N (same TQFP-144 footprint, slower -2 speed grade) or EP1K10TC144-1N (slowest -1 speed grade). All three share identical pinout and package; substituting -2N or -1N for -3N is acceptable when the design meets the slower timing bin constraints, often saving 20-30% on unit cost.

Can EP1K10TC144-2N replace EP1K10TC144-3N?

Yes. The EP1K10TC144-2N is pin-to-pin compatible with the EP1K10TC144-3N in the same TQFP-144 package. The only difference is the speed grade (-2 is slower than -3). If your design has adequate timing margin, you can drop a -2N into a -3N socket without any PCB or firmware changes.

Where to download the EP1K10TC144-3N datasheet PDF?

Руководство по выбору

Choose the EP1K10TC144-3N when you need the fastest 80 MHz timing bin in the 10K-gate ACEX 1K family with industrial temperature support and a TQFP-144 footprint. It is the right choice for PCI peripherals, glue logic, mid-density bus bridges, and ASIC replacement designs that target the 33 MHz PCI bus or any synchronous interface up to 80 MHz. Choose EP1K10TC144-2N if your design has timing margin and you can save cost; choose EP1K10TC144-1N for lowest cost when operating well below 40 MHz. For higher I/O counts, migrate to EP1K10QC208-3N (208-pin PQFP, 147 user I/Os). For modern tooling and longer lifecycle, evaluate the EP1C6TC144-8 (Cyclone, TQFP-144) - it requires a one-time design revalidation but offers active product support.

Заметки по проектированию

The EP1K10TC144-3N requires two supply rails: VCCINT = 2.5 V for the core and VCCIO = 3.3 V or 5 V for the user I/Os (PCI-compliant at 5 V). Power sequencing should bring up VCCINT before or simultaneously with VCCIO to prevent bus contention; add a 100 uF bulk capacitor and 0.1 uF decoupling per VCCINT/VCCIO pin pair. Estimated: a fully utilized EP1K10 with 80 MHz toggle draws approximately 200-400 mA on VCCINT (per ACEX 1K datasheet power calculator). Decoupling must keep the 2.5 V ripple under 50 mV.

Place the EP1K10TC144-3N with matched-length clocks to within 1 cm, and route configuration and JTAG signals (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0, TDI, TMS, TCK, TDO) with short, guarded traces. The dual-port EAB RAM benefits from localized routing: keep EAB-related signals within one LAB neighborhood. The TQFP-144 has a 0.5 mm lead pitch; use 0.15 mm/0.20 mm trace/space rules and at least 8 mil via-in-pad or tented vias for thermal relief.

The EP1K10TC144-3N uses SRAM-based configuration, so a configuration PROM (EPC2, EPC4, or compatible serial flash) is mandatory for non-volatile boot. Without it, the FPGA loses configuration on power-down. The 'N' suffix denotes industrial temperature range; omitting it (e.g., EP1K10TC144-3) yields the commercial-temp variant and may fail in industrial environments. Estimated: commercial temp is 0C to +70C while industrial is -40C to +85C for the -3N.
