EP1K10TC144-2 개요

The Altera (now Intel) EP1K10TC144-2 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGA) delivering 10,000 typical gates, 576 logic elements (LEs) and 12,288 RAM bits in a 144-pin LQFP (TQFP) package. The device integrates an enhanced embedded array for implementing megafunctions such as efficient memory and specialized logic functions, with dual-port RAM capability. It is fabricated on a 2.5 V core process and is offered in a commercial temperature grade.

An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be re-programmed after manufacture to implement arbitrary digital logic. FPGAs sit at the top of the programmable logic hierarchy between CPLDs (less complex, non-volatile, lower density) and ASICs (highest density, fixed function). The ACEX-1K family was Altera's first SRAM-based, look-up-table (LUT) FPGA family, designed as a low-cost System-On-a-Programmable-Chip (SOPC) integration platform bridging CPLD simplicity with FPGA density.

Key features include 92 user I/O pins, dual-port embedded array blocks (EABs), in-system programmability via JTAG, and support for multiple I/O standards including LVTTL, LVCMOS and PCI. The device operates from a 2.5 V core supply with 3.3 V tolerant I/O options, and the 144-LQFP (also written TQFP-144) footprint is a JEDEC-standard surface-mount package with 1.0 mm pitch.

The ACEX-1K architecture uses a fine-grained LUT-based logic element feeding into a hierarchical routing fabric with embedded array blocks (EABs) providing dual-port RAM and ROM. Per the Altera ACEX 1K Device Family datasheet (2.5V), each EAB can be configured from 256x8 to 4096x1 of true dual-port memory, enabling wide datapath and FIFO implementations without external memory. Configuration is volatile SRAM-based, so an external configuration memory (typically EPC2 or EPCQ) is required at power-up.

Typical applications include glue logic replacement, bridge and protocol conversion (e.g., PCI to local bus), low-volume ASIC prototyping, industrial control and instrumentation front-ends, and embedded control DSP co-processing. The 144-LQFP package is hand-solderable and well suited to prototype runs and low-to-mid volume production.

When designing with this part, note that the configuration memory (EPC2/EPCQ) must be specified separately and the JTAG chain length must be observed; because ACEX-1K is an older family, new designs should evaluate Cyclone IV/V or MAX 10 instead. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.

According to the Altera ACEX 1K Device Family datasheet (2.5V), this device targets low-cost System-On-a-Programmable-Chip (SOPC) integration.

How many user I/O pins does the EP1K10TC144-2 have?

The EP1K10TC144-2 provides 92 user I/O pins in the 144-LQFP package. The remaining pins are allocated to power, ground, JTAG, configuration mode selects, and dedicated clock inputs. This I/O count is well suited to interface bridging, control logic, and small datapath applications.

How many logic elements and memory bits does the EP1K10TC144-2 contain?

The EP1K10TC144-2 integrates 576 logic elements (LEs), 12,288 bits of embedded RAM distributed across 3 Embedded Array Blocks (EABs), and approximately 10,000 typical gates. Per the Altera ACEX 1K datasheet, each EAB supports dual-port RAM configurations from 256x8 up to 4096x1.

Is the EP1K10TC144-2 still in production?

No, the EP1K10TC144-2 is listed as obsolete by both Altera (now Intel) and major distributors. The ACEX-1K family was superseded by Cyclone, Cyclone II, and subsequent families. Inventory remains available through franchised distributors and the secondary market, but lead times can be extended. For new designs, Intel recommends Cyclone IV/V or MAX 10.

What package does the EP1K10TC144-2 use?

The EP1K10TC144-2 is packaged in a 144-pin LQFP, also written as TQFP-144 or LFQFP-144 depending on the manufacturer datasheet. The package has a 1.0 mm pin pitch and is hand-solderable, making it suitable for prototype and low-to-mid volume production runs. It is gull-wing SMT.

Where can I buy the EP1K10TC144-2?

The EP1K10TC144-2 can be sourced through franchised distributors including DigiKey (stock 6,016 pcs per Heisener data, fetched 2026-09-07), Mouser, Octopart-listed brokers, Heisener, Avaq, and Origin-IC. Because the part is obsolete, request firm quotes for lead time and verify lot/date code authenticity. Pricing varies from approximately $11.90/1000 to $18.50/1 unit as of 2026-09-07.

What is the price of EP1K10TC144-2?

As of 2026-09-07, the EP1K10TC144-2 prices are approximately $18.50 at qty 1, $16.75 at qty 10, $14.90 at qty 100, $13.25 at qty 500, and $11.90 at qty 1000 from major distributors. Prices fluctuate with market scarcity and obsolete-stock availability. Heisener lists in stock per data fetched 2026-09-07. Quote RFQ for current volume pricing.

What is the lead time for EP1K10TC144-2?

Lead time for the EP1K10TC144-2 varies from same-day shipping (when distributor stock exists) to 12+ weeks for factory or broker orders because the part is obsolete. Heisener reports estimated delivery of 2026-04-26 to 2026-05-01 with expedited shipping. For new designs, consider pin-compatible Altera ACEX-1K variants such as EP1K10TC144-1 or the Cyclone series.

What is the difference between EP1K10TC144-2, EP1K10TC144-1, and EP1K10TC144-3?

The ACEX-1K speed grades are -1 (slowest), -2 (mid-speed), and -3 (fastest). All three variants share the same 144-LQFP footprint and die, but the -3 grade offers higher Fmax at the cost of dynamic power. The EP1K10TC144-2 sits in the middle of the speed range and is the most commonly stocked grade. They are functionally pin-compatible drop-in alternatives.

What is the best drop-in replacement for the EP1K10TC144-2?

The closest drop-in replacements are other ACEX-1K speed grades in the same 144-LQFP package: EP1K10TC144-1 (slower), EP1K10TC144-1N, EP1K10TC144-2N, and EP1K10TC144-3N. All share the 144-LQFP footprint and the same ACEX-1K die. For modernization, the Altera Cyclone EP1C6T144C8 or Intel 10CL010YU256C8G (Cyclone 10 LP) are next-generation replacements, but require a Quartus redesign.

Is there a Xilinx equivalent to the EP1K10TC144-2?

The functional Xilinx equivalent family for the ACEX-1K 10K-gate class is the Spartan-II XC2S50 or Spartan-3 XC3S50. However, these are NOT drop-in pin-compatible - they use different packages, different I/O standards, and different bitstream/configuration flows. A Xilinx migration requires a complete PCB redesign and a switch from Quartus to ISE/Vivado toolchains.

Is there a Lattice equivalent for the EP1K10TC144-2?

Lattice offers the ECP3-70 series as a 70K-LUT equivalent density part, but the specific 144-LQFP pin-compatible replacement for ACEX-1K is the ispMACH LC4256Z (a 64-macrocell CPLD, lower density). For functional migration to a modern Lattice part, the ECP5 LFE5U-12 or Certus-NX is the recommended path, but neither is pin-compatible and a PCB redesign is required.

When should I choose the EP1K10TC144-2 over a Cyclone alternative?

Choose the EP1K10TC144-2 only when maintaining a legacy 2.5 V design or repairing existing production boards where a drop-in replacement is required. For new designs, the Altera Cyclone IV EP4CE6E22 or Cyclone 10 LP 10CL006YU256 offer 4x the logic, lower power, RoHS compliance, and active lifecycle support. The EP1K10TC144-2 is obsolete and not recommended for new product development.

Where can I download the EP1K10TC144-2 datasheet PDF?

The EP1K10TC144-2 datasheet is accessible through the Altera ACEX 1K Device Family datasheet, which covers the entire family. The datasheet PDF can be retrieved from third-party datasheet engines such as Alldatasheet.com, Digchip.com, or the IC-1101.com archived PDF. Note that Altera (Intel) officially classifies the ACEX-1K family as obsolete and the datasheet is provided for reference only.

What is the configuration memory required for the EP1K10TC144-2?

The EP1K10TC144-2 requires an external configuration device because its configuration is volatile SRAM-based. Compatible configuration memories include the Altera EPC2 (4 Mbit, 5.0 V or 3.3 V) for active serial mode or EPCQ16/EPCQ32 for newer design flows. JTAG programming is supported for in-system configuration and board-level testing. Always include a JTAG header for prototype boards.

Choose the EP1K10TC144-2 only when maintaining or repairing legacy ACEX-1K designs where a pin-compatible replacement is required and the supply chain can absorb obsolete-stock risk. For new designs, prefer the Altera Cyclone IV EP4CE6E22C8N or Cyclone 10 LP 10CL006YU256C8G, which offer 4-8x more logic, lower power, RoHS compliance, and active lifecycle support. Within the ACEX-1K family, choose EP1K10TC144-1N for lower-speed/cost designs, EP1K10TC144-2N (this part) for balanced performance, EP1K10TC144-3N for highest Fmax, or EP1K10QC208-2N when more than 92 user I/O are needed. For cross-vendor migration, Xilinx Spartan-II/XC2S50 and Lattice ECP3-70 are functional equivalents but require full PCB redesign - they are not drop-in replacements.

설계 노트

The EP1K10TC144-2 requires a clean 2.5 V core supply (VCCINT) and a separate 3.3 V (or 2.5 V) VCCIO supply for I/O banks. Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, and add a bulk 10 uF tantalum or ceramic near the package. The configuration memory (EPC2) must share a stable supply; backplane power sequencing is critical because ACEX-1K is volatile-SRAM based.

Use 4-layer PCB stack-up with continuous ground and power planes. Route JTAG (TCK/TMS/TDI/TDO) with 50 ohm controlled impedance and keep traces under 100 mm to avoid signal-integrity issues. Place the 144-LQFP with 0.4 mm wide traces and 0.2 mm spacing for escape routing. Provide a 10-pin JTAG header for in-system programming and boundary-scan test access.

Three common pitfalls: (1) forgetting the external EPC2/EPCQ configuration memory - ACEX-1K is volatile-SRAM, so without config memory the device powers up unconfigured; (2) mixing nSTATUS and nCONFIG polarity - both are active-low open-drain and require 10 kohm pull-ups; (3) exceeding 2.7 V on VCCINT during hot-plug events - use a sequenced power supply or hot-swap controller. Always verify MSEL0/MSEL1 mode-select resistor values match the chosen configuration mode.

Differential pairs (LVDS) require 100 ohm differential impedance; route the P and N traces within 0.1 mm of each other and keep length matching within 1 mm. For clock inputs, use a guard ground trace on both sides and series-termination at the source. The ACEX-1K family supports up to four global clock networks (CLK0-CLK3) and two PLLs; place the clock source within 50 mm of the dedicated clock pin for jitter control.
