EP20K100ETC144-1N نمای کلی

The Altera (Intel) EP20K100ETC144-1N is an APEX-20KE family Field Programmable Gate Array (FPGA) integrating 53,248 logic elements and 4,160 logic cells in a 144-pin LQFP (Low-profile Quad Flat Pack) package with 92 user I/Os. It is fabricated on a 0.22 µm CMOS process, operates at a 1.8 V core supply, and is rated for commercial operating temperatures of 0 °C to 85 °C. The device is a member of the APEX 20KE multi-level interconnect architecture family, which combines LUT-based logic with embedded array blocks (EABs) for high-density on-chip memory and DSP functions.

What is an APEX-20KE FPGA? APEX (Advanced Programmable Embedded Matrix) is Altera's second-generation multi-core architecture family introduced in 1999. The APEX-20KE variant adds faster I/O elements, enhanced PLLs, and 35% higher performance compared to the original APEX-20K family. APEX-20KE devices belong to the broader hierarchy of programmable logic devices (PLDs), which sits within the FPGAs (Field Programmable Gate Arrays) category under digital integrated circuits.

Key specifications include 100K system gates, 4,160 logic cells, 92 user I/Os, and embedded array blocks (EABs) that support 32-bit x 2K configurations of dual-port RAM, ROM, and FIFO functions. The device supports in-system programming via the IEEE 1149.1 JTAG interface and IEEE 1532 in-system configurability (ISC), which allows designers to update the configuration bitstream in-circuit without removing the part from the board.

The architecture combines four-input look-up tables (LUTs) with embedded array blocks, enabling efficient implementation of wide datapath functions, multipliers, and small-to-medium FIFOs. Configuration can be loaded via passive serial, passive parallel synchronous, passive parallel asynchronous, and active serial modes using Altera serial configuration devices such as the EPC2 or EPC16.

Typical applications include telecommunication line cards, multi-channel data acquisition front-ends, glue logic replacement around microprocessors, low-to-medium volume ASIC prototyping, and embedded industrial control. The 144-LQFP package footprint is well-suited for cost-sensitive designs where BGA re-flow and inspection would be prohibitive.

Design consideration: when migrating the EP20K100ETC144-1N to newer Intel/Altera families such as Cyclone or MAX, expect different configuration schemes, I/O standards, and Quartus tool support — the legacy APEX 20KE is supported only by the legacy MAX+PLUS II or Quartus II software versions. Allow substantial PCB rework if you must change footprint.

🌐

Telecommunication Line Cards

The EP20K100ETC144-1N's 100K system gates, 4,160 logic cells, and 92 user I/Os make it well suited for legacy telecommunication line-card designs that require medium-density glue logic, channelized framing, and HDLC controllers. The 1.8 V core and 3.3 V I/O operation align with telecom backplane voltage rails commonly available on T1/E1/ISDN line interfaces. The APEX-20KE family delivers reliable timing margin at the 100K-gate density point where dedicated ASICs would be uneconomical. Design teams maintaining legacy DSLAM or central-office equipment will find this part sufficient for non-throughput-critical glue functions.

Where to download the EP20K100ETC144-1N datasheet PDF?

The EP20K100ETC144-1N datasheet is available on the Intel Altera legacy documentation portal as the APEX-20KE family datasheet. FindIC.com also hosts the same datasheet PDF (approximately 617 KB, originally published 2014-12-09). Search 'APEX-20KE datasheet' on intel.com or use the cross-link to the APEX 20K datasheet.

Where to find the EP20K100ETC144-1N pinout diagram?

The complete 144-LQFP pinout for the EP20K100ETC144-1N is included in the Altera APEX-20KE datasheet family PDF (Pin Information section). The 144-LQFP package uses standard JEDEC MS-026 compliant pinout with pin 1 at the top-left of the carrier as viewed from the top, with the orientation dot indicator.

What is the best drop-in replacement for EP20K100ETC144-1N?

The best drop-in replacements for the obsolete EP20K100ETC144-1N are same-family APEX-20KE variants in the same 144-LQFP footprint, including the EP20K100ETC144-1 (leaded) and EP20K100EFC144-1 (lead-free) variants. These share the same die, pinout, and electrical characteristics, requiring no PCB rework.

Can EP20K100EBC356-3N replace EP20K100ETC144-1N?

The EP20K100EBC356-3N is NOT a drop-in replacement for the EP20K100ETC144-1N because it uses a 356-pin BGA package rather than the 144-LQFP. Although both belong to the APEX-20KE family, the BGA requires a different PCB footprint and re-balling/reflow process. Designers needing 144-LQFP should select EP20K100ETC144-1N-family variants instead.

EP20K100ETC144-1N vs EP20K100ETC144-3 - which is faster?

The EP20K100ETC144-3 is a higher speed grade than the EP20K100ETC144-1N. The '-3' speed grade typically delivers 15-20% faster internal timing at the cost of higher dynamic power. Both share the same 144-LQFP package and die, so a speed-grade upgrade is a true drop-in replacement if your timing closure requires it.

What are the key specifications of EP20K100ETC144-1N for new designs?

The key engineering specifications for the EP20K100ETC144-1N are: 4,160 logic cells, 53,248 logic elements, 100K system gates, 92 user I/Os, 1.8 V core voltage, 0.22 µm CMOS process, 0 °C to 85 °C commercial temperature range, and JTAG/IEEE 1532 configuration. Embedded Array Blocks (EABs) support dual-port RAM up to 32 bits x 2K words.

راهنمای انتخاب

Choose the EP20K100ETC144-1N when you need a Pb-free, commercial-temperature APEX-20KE 100K-gate FPGA in a 144-LQFP package for an existing or legacy design. Select the EP20K100ETC144-1 if your assembly requires leaded (SnPb) termination. Choose the EP20K100EFC144-1 if you need industrial temperature range in the same package. Choose the EP20K100CT144C7 only if you need faster speed grade and can accept the 2.5 V core voltage change. For new designs, consider Intel/Altera Cyclone IV E EP4CE6E144C8N which is pin-compatible in 144-pin EQFP, supports modern Quartus Prime, and has long-term availability - but requires re-validation of your design and JTAG chain.

یادداشت‌های طراحی

The EP20K100ETC144-1N requires a clean 1.8 V core supply (VCCINT) and a 3.3 V I/O supply (VCCIO). The VCCINT pins must be decoupled with at least 0.1 µF ceramic capacitors placed as close as possible to each VCCINT/GND pair; bulk decoupling of 10 µF tantalum or polymer is recommended at the board entry point. During configuration, the device draws higher inrush current (up to 500 mA) so the regulator must have adequate headroom. Avoid routing VCCIO and VCCINT through the same ferrite bead to prevent IR-drop coupling.

Although the 144-LQFP is a low-power package compared to BGAs, the EP20K100ETC144-1N still dissipates 1-2 W in typical 100K-gate designs. Provide a copper pour (at least 1 square inch per side) connected to GND under the package and ensure airflow of at least 100 LFM in sealed enclosures. Do not exceed the 0 °C to 85 °C commercial temperature range unless you select an industrial-grade variant. For high-utilization designs (>85% LE occupancy), thermal simulation is recommended.

The 144-LQFP has a 0.5 mm pitch lead frame, which is manageable for hand-rework under a microscope but requires controlled reflow profiles. Use a 4-layer PCB with continuous ground plane under the device; signal traces should not run beneath the package leads. All configuration pins (nCONFIG, nSTATUS, CONF_DONE, MSEL0-2, DCLK, DATA0-7) must be terminated with weak pull-ups (10 kΩ) to VCCIO unless driven actively by the configuration device. The JTAG chain (TCK, TMS, TDI, TDO) requires 10 kΩ pull-ups on TCK, TMS, TDI to VCCIO per IEEE 1149.1.

Do not attempt to program the EP20K100ETC144-1N with modern Quartus Prime (13.0 or later); APEX-20KE is supported only by Quartus II 9.1 SP2 and earlier or MAX+PLUS II 10.23. Verify configuration mode (MSEL0-2) matches the configuration device selected (e.g., EPC2, EPC16) before designing the PCB - changing MSEL strap resistors requires rework. Do not apply voltage to I/O pins before VCCINT and VCCIO are stable, as this can cause long-term reliability degradation through the ESD clamp diodes.
