EP20K100ETC144-2N 概述

The Altera (Intel) EP20K100ETC144-2N is an APEX-20KE family Field Programmable Gate Array (FPGA) integrating 100K system gates, 4160 logic elements, and 53248 bits of embedded RAM, housed in a 144-pin LQFP package with 92 user I/Os. Manufactured on a 0.22 µm all-layer copper-metal process, this FPGA delivers up to 250 MHz core performance and operates from a 1.8 V core supply with multi-voltage I/O support.

An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (LABs/CLBs), programmable interconnects, and I/O cells that can be re-programmed post-manufacturing to implement arbitrary digital logic. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs), alongside CPLDs (Complex PLDs) and SPLDs (Simple PLDs). The APEX-20KE family specifically combines logic, memory (ESBs - Embedded System Blocks), and high-speed I/O on a single die, targeting data-path and datapath-intensive applications. Compared to CPLDs, FPGAs offer far greater logic density and on-chip memory; compared to ASICs, FPGAs provide rapid prototyping and field re-programmability.

Key features of the EP20K100ETC144-2N include 416 LABs/CLBs, 4 ESBs providing dual-port RAM, 263,000 typical gate count, 92 maximum user I/Os, JTAG IEEE 1149.1 boundary-scan, and 1.6 ns propagation delay. The device supports in-system programmability via the FastON connection, and includes clock-lock circuits for PLL-free clock management.

Typical applications for the EP20K100ETC144-2N include telecommunications line cards, industrial control systems, and legacy digital design replacement. The 144-pin LQFP footprint makes this part attractive for cost-sensitive, prototype-friendly designs where BGA assembly is impractical.

When designing with this device, ensure your logic utilization stays below approximately 70% to preserve timing closure margins. The 144-LQFP package imposes I/O limitations versus BGA variants; consider EP20K100EBC356 or EP20K100EFI672 if higher pin count is required.

What is the operating temperature range of EP20K100ETC144-2N?

The EP20K100ETC144-2N operates from 0 C to 85 C junction temperature per the APEX-20KE datasheet family specification. This commercial-grade temperature range suits telecom infrastructure and industrial-control applications but excludes extended-temp automotive and military use. For industrial-grade, consider EP20K100EFC324 or EP20K100EBC356 variants. According to Altera datasheet (APEX 20KE Data Sheet), the 0-85 C range reflects the commercial (C) suffix. Heisener lists in stock as of 2026-09-07.

How many user I/O pins does EP20K100ETC144-2N have?

The EP20K100ETC144-2N provides 92 user I/O pins within its 144-LQFP (TQFP) package. Per DigiKey listing (4160786), this is the maximum I/O count available in the 144-pin LQFP variant of the EP20K100E family. The remaining package pins are allocated to power, ground, JTAG, and configuration. If your design requires more I/O, consider the 240-pin EP20K100EQC240 or 356-pin EP20K100EBC356 in the same family. Heisener confirms 144-TQFP package with 92 I/O.

What is the maximum operating frequency of EP20K100ETC144-2N?

The EP20K100ETC144-2N delivers up to 250 MHz core performance according to multiple distributor sources including FPGAkey and Jotrin Electronics (as of 2026-09-07). This frequency applies to internal logic-array operation; actual system Fmax depends on design utilization, routing congestion, and timing constraints. The APEX-20KE architecture provides built-in clock-lock circuits for skew control. For designs requiring higher speed, consider Cyclone or Stratix successor families.

How much embedded memory does EP20K100ETC144-2N have?

The EP20K100ETC144-2N integrates 53248 bits of embedded RAM organized across 4 Embedded System Blocks (ESBs), per DigiKey product listing (4160786). Each ESB supports dual-port RAM, ROM, and CAM configurations. The 4160 logic elements combined with 53248 RAM bits provide 100K typical gate-equivalent capacity. To compare, the APEX-20KE 400-series devices scale to 160K gates; for greater memory, consider APEX-II or Excalibur families.

Where can I buy EP20K100ETC144-2N online?

What is the lead time for EP20K100ETC144-2N?

Lead time for EP20K100ETC144-2N varies by distributor. Heisener quotes estimated delivery Mar 8 to Mar 13, 2026 from order date as of 2026-09-07 listing. DigiKey typically ships same-day for stocked inventory (3,000+ pieces reported in distribution channels). Given the part is NRND (Not Recommended for New Designs) per Altera lifecycle, supply may decline; long-term buyers should consider EP20K100E equivalents or Cyclone/Stratix successors for new designs.

Is EP20K100ETC144-2N in stock at distributors?

Yes, the EP20K100ETC144-2N has distributor stock as of 2026-09-07. Heisener reports in stock. DigiKey also lists availability. However, because Altera has marked the APEX-20KE family as NRND (Not Recommended for New Designs), stock levels may fluctuate. Production-status replacement guidance: consider EP20K100ETC144-1X (speed-grade -1) or EP20K100EQC240-2X (240-pin variant) for new designs requiring similar logic capacity.

EP20K100ETC144-2N vs EP20K100EFC324-2X - which is better for high-I/O designs?

The EP20K100EFC324-2X offers significantly more I/O (246 user I/Os in 324-pin FBGA) compared to the EP20K100ETC144-2N's 92 I/Os in 144-LQFP.

选型指南

Choose the EP20K100ETC144-2N for new design or production use requiring a 100K-gate APEX-20KE FPGA in a prototype-friendly 144-LQFP package with 92 I/Os and commercial temperature range (0-85 C). This part delivers 250 MHz Fmax with 1.8 V core and 4 ESBs for embedded memory. Choose EP20K100ETC144-1N if you need the same 144-LQFP footprint at slightly lower speed grade (cost reduction). Choose EP20K100ETC144-1X for industrial/outdoor applications requiring -40 to 85 C extended temperature. Choose EP20K100CT144C8 if your design is memory-light (no ESB requirement) and cost is the primary driver. Avoid APEX-20KE family for new designs due to NRND lifecycle; migrate to Cyclone II/III for new projects requiring similar density.

设计说明

Estimated: at typical APEX-20KE utilization (50% logic, 50% RAM) with 1.8 V core and 25% I/O toggle at 100 MHz, total power dissipation is approximately 0.5-1.5 W. The 144-LQFP package (20x20 mm) provides thermal resistance theta_JA around 35-45 C/W depending on PCB copper area. For reliable operation in commercial 0-85 C ambient, ensure at least 100 cm^2 of 4-layer PCB copper pour tied to VCCINT plane. Inputs/outputs above 85 C junction require EP20K100ETC144-1X (extended temp) or EP20K100E variants.

Place 0.1 uF decoupling capacitors within 5 mm of every VCCINT pin and VCCIO bank pin, with bulk 10-47 uF tantalum or ceramic caps on the VCCINT rail near the device. The 144-LQFP (TQFP) package has 0.5 mm pin pitch requiring fine PCB tolerances; use ENIG or immersion-silver surface finish for reliable assembly. Maintain continuous ground plane on layer 2 to provide controlled-impedance current return paths for the 8 I/O banks. JTAG signals (TCK, TMS, TDI, TDO) require series 33 ohm resistors near the FPGA for signal integrity.

Do not assume the APEX-20KE architecture is software-compatible with newer Altera/Intel FPGA families. The APEX-20KE uses Quartus II version 13.0 or earlier; the Quartus Prime toolchain does not support APEX-20KE designs. For migration, retargeting bitstreams from APEX-20KE to Cyclone or Stratix requires HDL re-synthesis, not just bitstream conversion. The 1.6 ns propagation delay is pin-to-pin; internal LAB routing adds delay, so do not over-estimate Fmax for critical paths. Configuration mode pins (MSEL0/MSEL1/MSEL2) must be tied to specific logic levels for AS, PS, or JTAG modes - floating MSELs cause configuration failure.
