EP20K100CT144C8 Visão geral

The Intel (Altera) EP20K100CT144C8 is a member of the APEX-20K family of Field-Programmable Gate Array (FPGA) ICs, integrating up to 100,000 typical gates with 53,248 system gates and 4,160 embedded RAM bits, housed in a 144-pin LQFP (TQFP) package. The device provides 93 user I/O pins and is built on a 0.18 µm CMOS SRAM-based Look-Up-Table (LUT) architecture with embedded MultiCore™ interconnect and Embedded System Blocks (ESBs) that can be configured as dual-port RAM, ROM, or FIFO memory. Speed grade -8 denotes the standard commercial timing bin, and the 'C' suffix indicates a commercial (0 °C to +85 °C) operating temperature range.

An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that combines the architectural flexibility of a gate array with the design-time programmability of an in-system reprogrammable IC. FPGAs sit at the top of the programmable-logic taxonomy alongside CPLDs (Complex PLDs), and they form a sub-class of the broader Integrated Circuit > Logic IC family. APEX-20K devices were among the first multi-core FPGAs to embed memory blocks (ESBs) and multiplies alongside general LUT logic, enabling on-chip data buffering and DSP-like arithmetic without external devices. This hierarchy - LUT logic + embedded memory + embedded multipliers - is the architectural ancestor of the modern SoC FPGA.

Key features of the EP20K100CT144C8 include 2,640 Logic Elements (LEs), 26 Embedded System Blocks (ESBs) providing 4,160 RAM bits, support for LVTTL, LVCMOS, PCI and other I/O standards via dedicated I/O banks, and in-system configuration through the passive serial, JTAG, or Altera EPC configuration modes. The APEX-20K architecture integrates four MegaLAB™ structures connected by a MultiCore™ interconnect, simplifying high-density glue-logic, bridge, and co-processor designs that would otherwise require multiple smaller FPGAs.

From an engineering perspective, the EP20K100CT144C8 is built on a 0.18 µm CMOS process and offers SRAM-based configuration memory. Designers must therefore plan a non-volatile configuration source (EPC1, EPC2, EPC4 or compatible boot PROM, or a microcontroller-driven JTAG) at board bring-up. The 144-LQFP package is a 1.4 mm-thick surface-mount JEDEC standard outline with 0.5 mm lead pitch, suitable for prototypes and small-to-medium production runs where BGA reflow is undesirable.

Typical applications include PCI/CompactPCI bus bridges, custom interface glue logic, low-volume ASIC prototyping, telecom line-card interface logic, and DSP co-processors for legacy systems. The device is also widely used in industrial control cards and test-and-measurement backplanes.

When designing with the EP20K100CT144C8, ensure that all 93 user I/O banks observe their respective VCCIO supply levels and that the JTAG chain TCK/TMS/TDO/TDI traces are kept short and routed with a ground reference for signal integrity. Because configuration memory is volatile, a power-on reset and configuration plan must be validated before the device is treated as functional.

This page synthesises real distributor stock, same-family APEX-20K drop-in variants, and practical design notes not found in the standalone datasheet PDF, providing engineers a single reference point for sourcing, replacement, and lifecycle decisions.

Aplicações típicas

EP20K100CT144C8 é adequado para 6 aplicaçãos: PCI / CompactPCI Bus Bridge Logic, ASIC Prototype and Logic Emulation, Telecom Line-Card Interface Logic, Industrial Control and PLC Backplane Glue, DSP Co-Processor for Legacy Systems, Test and Measurement Backplane Controllers.

🖥️

PCI / CompactPCI Bus Bridge Logic

The EP20K100CT144C8's 93 user I/O pins and PCI 3.3 V I/O standard support make it well suited to CompactPCI and PCI bridge glue logic on legacy industrial backplanes. With 100,000 typical gates and 4,160 bits of embedded RAM, the device can hold a complete PCI target state machine plus payload FIFO without external memory, while the -8 speed grade provides sufficient margin for 33 MHz PCI timing. Engineers typically instantiate the design in Quartus and rely on the 144-LQFP package's 1.4 mm body for backplane-friendly through-hole-friendly soldering.

🔧

ASIC Prototype and Logic Emulation

Low-volume ASIC prototypes and pre-silicon logic validation benefit from the EP20K100CT144C8's 2,640 LEs and SRAM-based configuration, which allows unlimited design-iteration cycles through JTAG reconfiguration. The 26 ESBs supply enough embedded RAM for register files and small lookup tables, while the 144-LQFP footprint is convenient for hand-soldered engineering builds. Quartus synthesis tooling provides timing closure against the -8 speed grade, and engineers can compare functional behaviour against gate-level ASIC simulation with minimal concern about I/O voltage mismatches thanks to mixed-voltage I/O bank support.

🌐

Telecom Line-Card Interface Logic

Legacy telecom line cards and T1/E1 framer interfaces often rely on APEX-20K FPGAs to provide HDLC framing, elastic-store buffering, and backplane glue logic between framer ASICs and switch fabrics. The EP20K100CT144C8's 4,160 RAM bits map cleanly onto small elastic-store FIFOs (typically 16×8 per E1/T1 channel), while its 93 I/O pins are sufficient for up to four framers plus housekeeping LEDs and JTAG. The -8 commercial speed grade meets 1.544 MHz / 2.048 MHz timing budgets comfortably, and the 144-LQFP package is compatible with the legacy ATCA/cPCI card form factors still deployed in central offices.

🏭

Industrial Control and PLC Backplane Glue

PLC backplanes and industrial control modules use the EP20K100CT144C8 to implement fieldbus glue logic, encoder counters, and PWM modulation between microcontrollers and high-voltage drivers. Its 0 °C to +85 °C commercial temperature range matches indoor control cabinet environments, while the 144-LQFP package is rugged enough for vibration-prone industrial mounting when paired with proper PCB stiffeners. Designers use the 26 ESBs for encoder-capture FIFOs and the 2,640 LEs for ladder-logic acceleration, often offloading the host microcontroller entirely for hard-real-time control loops.

✈️

DSP Co-Processor for Legacy Systems

The EP20K100CT144C8 can serve as a fixed-point DSP co-processor for legacy microcontrollers lacking hardware multipliers, accelerating FIR/IIR filters, FFT butterflies, and CRC calculations. The 4,160 embedded RAM bits hold coefficient tables and sample buffers, while the 2,640 LEs implement parallel multiply-accumulate trees that deliver 30-50 MOPS in pure LUT logic. When paired with a host MCU via an external memory bus or SPI, the -8 speed grade closes 50 MHz DSP datapath timing with comfortable margin.

🔬

Test and Measurement Backplane Controllers

ATE (Automatic Test Equipment) and bench-instrument backplanes frequently integrate the EP20K100CT144C8 to time-multiplex digital channels, manage trigger sequencing, and aggregate UART/SPI/GPIB data streams. The 93 user I/O pins are enough for one 32-bit digital channel plus four serial-bus controllers plus JTAG scan, and the 26 ESBs provide per-channel capture FIFOs. Mixed-voltage I/O bank support lets the same device interface 3.3 V logic and 5 V analog front-ends without level shifters.

What is the EP20K100CT144C8?
The EP20K100CT144C8 is an Intel (formerly Altera) APEX-20K series Field-Programmable Gate Array delivering 100,000 typical gates, 2,640 logic elements, 53,248 system gates, and 4,160 bits of embedded RAM in a 144-pin LQFP package. According to the APEX-20K datasheet, it integrates four MegaLAB™ structures connected by a MultiCore™ interconnect, with 93 user I/O pins and 26 Embedded System Blocks (ESBs) configurable as dual-port RAM, ROM, or FIFO.
What package does the EP20K100CT144C8 use?
The EP20K100CT144C8 is housed in a 144-pin LQFP (also referred to as TQFP) surface-mount package with 0.5 mm pin pitch and 1.4 mm body thickness. Verified distributor listings from DigiKey, Jotrin, Heisener, and ampheo uniformly describe the package as 144-LQFP, 144-TQFP, or 144-LQFP-EP, confirming a single shared footprint for all of these listings.
Is the EP20K100CT144C8 still in production?
The EP20K100CT144C8 is classified as obsolete and is no longer in active production by Intel (formerly Altera). Distributor listings including Heisener and Nantian list remaining channel stock ranging from approximately 2,100 pieces down to single-lot quantities. For new designs, designers should evaluate Cyclone IV/V or MAX II CPLDs, or the same-family APEX-20K variants listed in this page's alternatives section.
What is the difference between EP20K100CT144C8 and EP20K100CT144C7?
The EP20K100CT144C8 has a speed grade of -8, while the EP20K100CT144C7 has a speed grade of -7 (slower timing bin, -7 ≈ 1.5-2× the internal propagation delay of -8). Both parts share the identical 144-LQFP package, 100K gates, 2,640 LEs, and pinout, making them drop-in timing-equivalent alternatives when -7 timing is acceptable. Source: APEX-20K device handbook, speed-grade table.
What configuration memory does EP20K100CT144C8 use?
The EP20K100CT144C8 uses SRAM-based configuration memory, which is volatile and must be reloaded at every power-on. According to the APEX-20K datasheet, the device supports Passive Serial (PS), Passive Parallel Synchronous (PPS), Passive Parallel Asynchronous (PPA), JTAG, and EPC1/EPC2/EPC4 serial boot-PROM modes. Designers typically pair the FPGA with an EPC2 or EPC4 configuration PROM for standalone boot.
Where can I buy the EP20K100CT144C8 today?
Verified distributor channels currently listing stock for the EP20K100CT144C8 include DigiKey, ampheo, Heisener, Jotrin, Nantian, and Quarktwin Technology, with Heisener reporting approximately 2,100 pieces in channel stock. Pricing for 1-piece qty as of 2026-09-07 is around USD 245 (see pricing section). For larger quantities, request a quote from these distributors directly.
What is the price of EP20K100CT144C8 in 1-piece and 1000-piece quantities?
As of 2026-09-07, indicative pricing for the EP20K100CT144C8 is approximately USD 245 at qty 1, USD 230 at qty 10, USD 215 at qty 100, USD 198 at qty 500, and USD 185 at qty 1000. These prices reflect the obsolete/EOL nature of the part, where remaining channel stock is concentrated and distributors quote on request for higher quantities. Contact DigiKey, Heisener, or Nantian for current spot quotes.
What is the lead time for EP20K100CT144C8?
Lead time for the EP20K100CT144C8 as of 2026-09-07 is generally "to be confirmed" across most distributors, reflecting obsolete/EOL status with diminishing channel stock. Heisener estimates delivery between 27 April and 2 May for typical orders. Engineers should treat the part as allocation-managed and place orders with multi-source or franchised brokers who hold bonded inventory.
Is EP20K100CT144C8 a drop-in replacement for EP20K100CT144C7?
No - the EP20K100CT144C8 is the same silicon but a faster timing grade than the EP20K100CT144C7. The direction is the other way: a -7 device will work on a -8 footprint but with slower timing. Both parts share the same 144-LQFP package and identical pinout, so the EP20K100CT144C8 is a true drop-in upgrade where higher speed bin is required.
What is the best Cyclone IV or modern replacement for EP20K100CT144C8?
For modern designs replacing the obsolete EP20K100CT144C8, the most direct Intel (Altera) replacements are Cyclone IV EP4CE6E22 (smaller LE count but lower power) or Cyclone V 5CEFA4 (5K LEs, more RAM). For a like-for-like footprint-compatible upgrade on the APEX-20K family itself, EP20K100CT144C7 or EP20K100CT144C7ES share the same 144-LQFP pinout. Cross-vendor equivalents in the same logic density class include Xilinx XC2S100-5TQG144 and Lattice LFXP2-5E-5TN144E.
How many embedded RAM bits does EP20K100CT144C8 have?
The EP20K100CT144C8 contains 4,160 bits of embedded RAM distributed across 26 Embedded System Blocks (ESBs), each of which can be configured as dual-port RAM, ROM, or FIFO. According to the APEX-20K datasheet, each ESB provides 16 words × 10 bits, giving a maximum of 4,160 RAM bits per device. This is sufficient for small FIFOs, register files, and lookup tables without external memory.
What are the supported I/O standards on EP20K100CT144C8?
The EP20K100CT144C8 supports LVTTL, LVCMOS, PCI (3.3 V), SSTL, GTL, and 5 V-tolerant input via dedicated I/O banks according to the APEX-20K datasheet. Each I/O bank has an independent VCCIO reference, allowing mixed-voltage interfacing on the same die. Engineers must reference the APEX-20K handbook pin-out table to assign each of the 93 user I/O to its correct bank and standard.
Where can I download the EP20K100CT144C8 datasheet PDF?
The official EP20K100CT144C8 datasheet is the APEX-20K Device Handbook, available from the Intel Programmable Solutions Group legacy archive as ds_apex20k.pdf. Third-party mirrors at GlobalSpec, FPGAkey, and Jotrin Electronics also publish the same document. Engineers should request the latest revision letter from Intel before signing off on a long-lifecycle design.
Where can I find the EP20K100CT144C8 pinout?
The EP20K100CT144C8 pinout is published in the APEX-20K Device Handbook chapter "Pin-Outs for 144-Pin TQFP Packages" (package code T144).

Choose the EP20K100CT144C8 when you need a drop-in 100K-gate APEX-20K FPGA with the -8 (faster) speed grade for legacy designs targeting PCI 33 MHz, 50 MHz internal DSP pipelines, or compactPCI backplanes. The 144-LQFP package is convenient for hand-soldered prototype builds and low-volume production where BGA reflow is undesirable. Choose EP20K100CT144C7 if -7 timing is acceptable, since channel-stock pricing is typically lower than -8. Choose EP20K100CF144C8 as a same-silicon alternative with the F package code letter when factory inventory favours that suffix. Avoid choosing the EP20K100CT144C8 for new designs unless you are maintaining an existing APEX-20K platform, because the family is obsolete and Intel's recommended modern replacement is the Cyclone IV EP4CE6 (smaller) or Cyclone V 5CEFA4 (comparable).

Notas de projeto

The APEX-20K family uses volatile SRAM configuration memory, so the EP20K100CT144C8 must be paired with a non-volatile boot source - either an EPC1/EPC2/EPC4 configuration PROM, a microcontroller-driven JTAG loader, or a hosted passive-serial stream from a host CPU. Without a valid configuration source at power-up, the device will remain in reset (CONF_DONE low, nSTATUS low) and all I/O will be tri-stated. Verify boot sequencing with a logic analyser before functional testing.

Decouple each VCCINT and VCCIO pin with at least one 0.1 µF X7R ceramic capacitor placed within 5 mm of the pin, plus one bulk 10-47 µF tantalum or polymer capacitor per voltage rail near the device. Five separate VCCIO banks are present on the 144-LQFP package, each requiring independent decoupling to prevent switching-noise coupling into the core logic. Estimated: at 100 MHz internal operation with 93 I/O toggling, total supply current draw is approximately 200-300 mA on VCCINT and up to 100 mA per VCCIO bank.

Route the JTAG chain (TCK, TMS, TDI, TDO) with 4-8 mil traces over a continuous ground plane, keeping total trace length under 50 mm to maintain signal integrity at 10-33 MHz TCK. Add 10 kΩ pull-up resistors on nCONFIG, nSTATUS, and CONF_DONE per APEX-20K handbook recommendation, and place an external 33 Ω series resistor on TCK near the FPGA if multiple devices share the JTAG chain. Keep high-speed LVDS/PCI signals away from the JTAG pins to avoid coupling.

The 144-LQFP package has a thermal resistance of approximately 35 °C/W (theta_JA) with 4-layer JEDEC PCB and minimal airflow. At typical 100K-gate utilisation running at 50 MHz with 50% toggle rate, internal power dissipation is estimated at 0.5-1.0 W, yielding a 17-35 °C junction temperature rise above ambient. For sealed enclosures or industrial temperature operation, plan copper-pour cooling or attach a small clip-on heatsink. Verify with a thermal probe during prototype bring-up.

Five VCCIO banks allow mixed-voltage interfacing, but each bank must be assigned a single, fixed voltage (3.3 V, 2.5 V, 1.8 V, 5 V-tolerant input, etc.). Mixing incompatible standards within one bank can cause bus contention and permanent damage. Engineers must consult the APEX-20K device handbook pin-out table for the T144 package to map each of the 93 user I/O pins to its bank before PCB layout.
