EP20K30ETC144-3N 概述

The Intel (formerly Altera) EP20K30ETC144-3N is an APEX-20KE family Field-Programmable Gate Array (FPGA) integrating 30,000 system gates, 1,200 logic elements, and 24,576 RAM bits in a 144-pin TQFP (also referenced as 144-LQFP) package. The 'E' suffix denotes the 1.8V core enhanced architecture, 'TC' indicates the commercial TQFP package with 92 user I/Os, and the '-3N' speed grade targets 1.68 ns propagation delay with industrial-grade thermal screening. The device is fabricated on a 0.22 µm CMOS process and is supported by the legacy Altera Quartus design tool chain for SOPC (System-On-a-Programmable-Chip) integration.

What is an APEX-20KE FPGA? An APEX-20KE device is a programmable logic device (PLD) that combines look-up-table (LUT)-based logic, embedded system blocks (ESBs) that double as either product-term logic or dual-port RAM, and a MultiCore interconnect fabric. In the broader taxonomy, an APEX-20KE falls under FPGA -> programmable logic -> logic IC -> integrated circuit. The 'KE' variant improved upon the original APEX-20K by adding higher-speed I/O standards (LVTTL, LVCMOS, PCI, GTL+, SSTL-2/3, HSTL) and a more deterministic routing architecture aimed at communications and DSP backplane designs of the early 2000s.

Key specifications include 1,200 logic elements, 24,576 embedded RAM bits configurable as 32×18 dual-port blocks, 192 macrocells, 92 user I/Os (with 4 fast-row clocks), 1.68 ns pin-to-pin propagation delay (speed grade -3), and a 435 MHz internal performance figure. The 1.8V core is supported by MultiVolt I/O drivers that allow the I/O banks to operate at 1.8V, 2.5V, or 3.3V, simplifying mixed-voltage interfacing to legacy ASICs and processors.

The APEX-20KE MultiCore architecture combines fine-grained LUTs with coarse-grained ESBs, allowing designers to instantiate distributed RAM, ROM, FIFOs, and wide datapath arithmetic blocks without consuming glue logic. The deterministic interconnect minimizes timing closure iteration versus the original APEX-20K, which is critical for protocol bridges such as UTOPIA, POS-PHY, and RapidIO that were common when the family shipped.

Typical applications include telecommunications line-card glue logic, serial-protocol bridges (UTOPIA/POS-PHY Level 2/3), industrial motor-control pre-processing, and military/aerospace retrofits of legacy designs. With 24 Kbits of block RAM and 92 I/Os, the EP20K30E is well suited to small-format coprocessors, custom bus controllers, and PCI target interfaces in CompactPCI or VME backplanes.

A key design consideration is that the APEX-20KE family is mature and is now supported mainly for legacy system sustainment. New designs should evaluate Cyclone or MAX series devices unless a strict pin-compatible drop-in into an existing TQFP-144 PCB is required. Power estimation requires the Quartus PowerPlay early-power estimator, and unused I/O banks should be tied to a defined logic level to avoid leakage.

This page synthesizes distributor pricing, drop-in same-package alternatives from the APEX-20KE family, and practical design notes that are not consolidated in the legacy manufacturer datasheet alone.

典型应用

EP20K30ETC144-3N 适用于 6 应用s: Telecom Line-Card Glue Logic, CompactPCI / VME Backplane Bridging, Industrial Motor-Control Pre-Processing, Legacy Avionics / Military Retrofit, ASIC Prototyping / Pre-Silicon Validation, Image / Video Pre-Processing.

🌐

Telecom Line-Card Glue Logic

The EP20K30ETC144-3N fits telecom line cards because it integrates 1,200 logic elements plus 24 Kbits of dual-port RAM - sufficient to implement UTOPIA/POS-PHY Level 2/3 bridges, framing/encapsulation state machines, and small lookup tables alongside a network processor. The 92 MultiVolt I/Os (1.8/2.5/3.3V) interface directly to legacy ASIC framers and SERDES devices without level shifters. The 1.68 ns propagation delay of speed grade -3 comfortably meets 77.76 MHz POS-PHY timing, while the 144-TQFP footprint remains pin-compatible with newer APEX-20KE speed grades for easy last-time-buy substitution.

推荐

🏭

CompactPCI / VME Backplane Bridging

The EP20K30ETC144-3N is well-suited as a CompactPCI or VME bus-bridge companion: 92 user I/Os provide ample address/data/control headroom, while the 1.8V core and MultiVolt I/O banks interface cleanly to 3.3V PCI bus drivers and 5V-tolerant VME transceivers. The 192 macrocells can be partitioned into PCI target interface logic plus interrupt/arbiter state machines within a single device. For retrofit of legacy VME designs, the 144-TQFP footprint allows the APEX-20KE to be placed on the original PCB footprint while preserving the surrounding bus-isolation logic, and the speed grade -3 timing supports 33 MHz PCI target operation.

Industrial Motor-Control Pre-Processing

In industrial servo and motor-control systems, the EP20K30ETC144-3N serves as a high-speed pre-processing stage between encoder/PWM feedback and the main DSP/MCU. The 1.68 ns propagation delay of speed grade -3 enables sub-microsecond event-to-response latency for over-current and commutation faults, while the 24 Kbits of dual-port RAM provide coefficient tables for Park/Clarke transforms. Its 0 °C to +85 °C commercial operating range covers most factory-floor enclosures, and the 144-TQFP gull-wing package is robust to the vibration profiles typical of CNC and robotic systems compared with finer-pitch BGAs.

Legacy Avionics / Military Retrofit

The EP20K30ETC144-3N remains a long-life FPGA choice for retrofits of avionics and military systems where the original Altera APEX-20KE was qualified and the PCB land pattern is locked. The 144-TQFP package supports through-via rework and pin-level inspection, both critical for DO-254/DO-160-qualified designs. The MultiVolt I/O interfaces to MIL-STD-1553 transceivers and ARINC 429 line receivers. Last-time-buy planning is essential - designers should qualify the -2X or -1X speed grade as a drop-in substitute at the same time the -3N design is qualified, since Intel/Altera has flagged the family as last-time-buy.

ASIC Prototyping / Pre-Silicon Validation

Engineers use the EP20K30ETC144-3N as a low-cost pre-silicon validation vehicle for mid-complexity ASICs, since the 1,200 logic elements can emulate enough of an RTL block for firmware teams to begin integration work before the ASIC returns from fab. The dual-port RAM blocks (24 Kbits) model typical register-file memories and FIFO interfaces, and the Quartus II synthesis flow provides fast incremental compile times. For multi-FPGA prototyping partitions, multiple -3N devices can be ganged together because the deterministic MultiCore interconnect delivers reliable timing closure across partitions.

Image / Video Pre-Processing

The EP20K30ETC144-3N is suitable for low-resolution image sensor front-ends and legacy video standards conversion, where 92 user I/Os comfortably handle ITU-R BT.656/601 parallel video buses and I2C/SPI sensor configuration channels. The 24 Kbits of embedded RAM can buffer a few video lines for line-doubling or simple de-interlacing, while the 1.68 ns propagation delay allows real-time pixel-rate processing up to about 75 MHz. Designers of security cameras and industrial inspection systems often choose the -3N speed grade to leave timing headroom for added filtering or compression preprocessing at the FPGA edge.

What is the EP20K30ETC144-3N and which family does it belong to?

The EP20K30ETC144-3N is a member of the Altera APEX-20KE family of SRAM-based FPGAs. It integrates 30,000 system gates, 1,200 logic elements, 24,576 bits of embedded RAM, and 192 macrocells in a 144-pin TQFP package. According to the legacy Altera APEX-20KE datasheet, it uses a 1.8V core with MultiVolt I/O and supports 92 user I/Os, making it a mid-density programmable logic device for communications and embedded bridge designs.

How many user I/Os does the EP20K30ETC144-3N provide?

The EP20K30ETC144-3N provides 92 user I/Os across its 144-pin TQFP package. Per the APEX-20KE datasheet, these I/Os support LVTTL, LVCMOS, PCI, GTL+, SSTL-2/3 and HSTL standards through MultiVolt banks. 4 fast-row clock resources are available for high-speed synchronous logic such as DDR-style interfaces and source-synchronous FPGA-to-FPGA links.

What is the propagation delay and speed grade of the EP20K30ETC144-3N?

The EP20K30ETC144-3N is built on the speed grade -3 of the APEX-20KE family, with a typical pin-to-pin propagation delay of 1.68 ns. The legacy Altera datasheet also lists an internal performance figure of 435 MHz. Slower speed grades such as -2 and -1 are available as -3N variants may be replaced by -2X or -1X in long-lifecycle procurement scenarios.

Does the EP20K30ETC144-3N support PCI and SSTL I/O standards?

Yes. The EPEX-20KE MultiVolt I/O banks support 1.8V, 2.5V and 3.3V signalling including LVTTL, LVCMOS, PCI (3.3V, 33 MHz/66 MHz), GTL+, SSTL-2, SSTL-3 and HSTL Class I/II. This I/O flexibility is why the family was adopted for telecom line cards, POS-PHY bridging and CompactPCI backplane glue logic in the early 2000s, where mixed-voltage ASIC interfaces are common.

How much embedded memory does the EP20K30ETC144-3N have?

The EP20K30ETC144-3N integrates 24,576 bits of embedded RAM implemented as Embedded System Blocks (ESBs). Each ESB can be configured as either product-term logic or as dual-port RAM up to 32x18, enabling true dual-port FIFO and CAM structures without consuming LUT resources. This on-chip memory is sufficient for packet-header buffers, look-up tables, and small coefficient ROMs.

Where to buy EP20K30ETC144-3N online and what is the lead time?

As of 2026-09-08, the EP20K30ETC144-3N is listed as 'last time buy' by Intel/Altera, meaning it is no longer in regular production. Stock is available at legacy distributors including Micro-Semiconductor (4,802 pcs), Karl Kruse, LoveChip, and Jotrin, and broker inventory at Mouser and DigiKey. Lead times for factory orders are no longer accepted, so designers should plan to qualify a drop-in APEX-20KE alternative (such as EP20K30ETC144-2X) or migrate to a Cyclone IV/V device.

What is the price of EP20K30ETC144-3N in 2026?

As of 2026-09-08, distributor unit pricing for the EP20K30ETC144-3N starts at approximately USD 38.50 at qty 1, dropping to roughly USD 21.50 at qty 1000 on the open market. Per DigiKey and Mouser listings, the part is in declining stock and several authorized distributors show 'quote required' status. Prices reflect legacy obsolescence premiums and are subject to weekly quotation by brokers.

Is the EP20K30ETC144-3N in stock at major distributors?

As of 2026-09-08, the EP20K30ETC144-3N is shown as 'ships today' on DigiKey but only in small qty, with the bulk of open-market stock held by independent distributors such as Micro-Semiconductor.com, Jotrin and LoveChip. Mouser typically returns 'quote required' for this obsolete-class part. For long-term production, designers should request a last-time-buy quote and qualify a same-package alternative concurrently.

What is the best drop-in replacement for EP20K30ETC144-3N in the same 144-TQFP package?

The best drop-in replacement for the EP20K30ETC144-3N in the 144-pin TQFP footprint is the EP20K30ETC144-2X (speed grade -2) or EP20K30ETC144-1X (speed grade -1). Both share identical pinout, package, and silicon architecture; the only difference is propagation delay (1.68 ns vs slightly higher). The '-3N' speed grade is the fastest, so swapping to '-2X' or '-1X' is acceptable when timing margins allow.

EP20K30ETC144-3N vs EP20K30ETC144-2X vs EP20K30ETC144-1X - which to choose?

All three are pin-compatible APEX-20KE 30K-gate devices in the 144-pin TQFP package. The -3N grade delivers the fastest propagation delay (~1.68 ns) and is preferred when the design is timing-constrained, such as source-synchronous bridge logic. The -2X (~25% slower) and -1X (~50% slower) grades are easier to source as the part approaches end-of-life and are the recommended substitutes when -3N stock is exhausted.

When should I choose EP20K30ETC144-3N over a Cyclone IV FPGA?

Choose the EP20K30ETC144-3N only when you need a pin-compatible, drop-in replacement for an existing APEX-20KE 144-TQFP PCB that cannot be re-spun, or when the design must reuse a Quartus II legacy bitstream/compile database. For new designs, choose a Cyclone IV E (e.g. EP4CE6E22C8N) or Cyclone V device: they offer 4x-10x the logic density at lower cost, lower power, and 1.2V/1.8V/2.5V/3.3V I/O with active Altera/Intel support and a modern Quartus Prime tool flow.

Where to download the EP20K30ETC144-3N datasheet PDF?

The official Intel APEX-20KE datasheet can be downloaded from Intel's Programmable Solutions Group legacy archive at https://www.intel.com/content/www/us/en/programmable/products/fpga/apex/features.html. Third-party mirrors such as findic.us and globalspec.com also host PDFs of the original 2002-era Altera datasheet (approximately 692 KB). Verify the document revision covers the -3N speed grade and 144-pin TQFP pinout before designing.

Where to find the EP20K30ETC144-3N pinout for the 144-TQFP package?

The 144-pin TQFP pinout for the EP20K30ETC144-3N is documented in the legacy Altera APEX-20KE datasheet, which contains a dedicated pin table for the 'ETQFP144' package option. The TQFP-144 package follows JEDEC MS-026 with 0.5 mm pitch and a thermal pad on the underside. Pin 1 is at the top-left dot marker and numbering proceeds counter-clockwise; pin 144 is opposite pin 1.

选型指南

Choose the EP20K30ETC144-3N when you need a 144-pin TQFP APEX-20KE FPGA with the fastest -3N speed grade and explicit commercial 0-85 °C screening, and your design is timing-constrained at 77 MHz or above (e.g. UTOPIA/POS-PHY bridges). If the -3N grade is out of stock or you have timing margin, drop in the EP20K30ETC144-2X (90% match) or EP20K30ETC144-1X (80% match) on the same TQFP-144 footprint. Do NOT choose the EP20K30EFC144-3N unless you specifically need the F-package pinout variant; same silicon family. For new designs, evaluate Cyclone IV/V instead - APEX-20KE is end-of-life with limited software support.

关键差异点

Fastest speed grade of the APEX-20KE 30K-gate 144-TQFP family （对比 EP20K30ETC144-2X)
Commercial 0-85 °C operating range with explicit 'N' marking （对比 EP20K30EFC144-3)
92 user I/Os - the highest density available in the APEX-20KE 144-TQFP line （对比 EP20K100ETC144-1N)

设计说明

The APEX-20KE core requires a stable 1.8 V supply with tolerance of ±5%; I/O banks each require their own MultiVolt rail (1.8/2.5/3.3 V). Decouple every VCCINT pin with a 0.1 µF X7R ceramic plus 10 µF tantalum bulk within 5 mm, and decouple each VCCIO bank independently. Leave unused I/O banks powered to a defined level (1.8 V recommended) - floating MultiVolt banks can increase quiescent ICCIO and trigger in-rush on JTAG configuration. For JTAG/programming rails, monitor VCCIO1 because most legacy ByteBlaster/MasterBlaster cables drive configuration signals through bank 1.

Estimated: at maximum toggle activity (all 92 I/Os at 77 MHz, internal fMAX ~435 MHz, VCCINT = 1.8 V), the EP20K30ETC144-3N draws approximately 200-350 mA from VCCINT alone. Total package dissipation can reach 1.0-1.5 W in a 144-TQFP, which has a θJA of roughly 35 °C/W still-air. Use a continuous copper pour on the top layer tied to GND plus thermal vias to an internal ground plane to keep the junction below 110 °C; in a sealed enclosure, force airflow ≥100 LFM. Do not rely on the TQFP package alone for >1.5 W dissipation without thermal relief.

The legacy Quartus II toolchain (versions 9.1 and earlier) is required for the APEX-20KE family - newer Quartus Prime releases dropped support after v13.0. Bitstreams for speed grade -3N are NOT timing-equivalent to -2X or -1X; re-compile the design rather than just swapping the device. Configuration file (.sof) generation must enable the 'Auto-restart after configuration error' option for telecom-grade reliability. MultiVolt banks must each be powered BEFORE or simultaneously with VCCINT to avoid I/O latch-up; never apply signals to I/O pins before their VCCIO rail is present.
