An FPGA (Field Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated I/O cells. FPGAs belong to the broader category of programmable logic devices (PLDs) and sit between fixed-function ASICs and software-programmable processors in terms of flexibility, performance, and NRE cost. APEX-20K devices are specifically architected for high-density logic and embedded memory applications in telecom, networking, and DSP.
Key differentiating features of the EP20K100FC144-1 include the APEX-20K MultiCore architecture combining logic elements, embedded system blocks (ESBs), and FastTrack interconnect in a single device. Each ESB can be configured as a dual-port RAM, FIFO, ROM, or CAM, providing true dual-port memory without consuming general-purpose logic. The device supports 3.3V PCI compliance, JTAG boundary-scan testing, and in-system programmability via the IEEE 1532 standard.
The architecture delivers up to 100K typical gates, 4,160 logic elements, 53,248 bits of embedded RAM, and 93 user I/O pins, while operating from a 2.5V core supply with 3.3V PCI-compatible I/O. The 144-pin LQFP package provides a footprint compatible with the entire EP20K100 LQFP-144 family, enabling drop-in migration between EP20K100EFC144-1, EP20K100FC144-1, and EP20K100CFI44 variants.
Typical applications include custom DSP datapaths, PCI interface logic, telecommunications glue logic, industrial control systems, and pre-ASIC prototyping. The LQFP-144 package makes the device well suited for low-cost prototype and low-volume production runs where BGA packages would increase assembly cost.
When designing with this part, ensure the 2.5V core supply and 3.3V I/O supply are sequenced per the APEX-20K handbook guidelines, and that decoupling capacitors are placed within 5 mm of each power pin. The EP20K100FC144-1 is now in legacy/EOL status; new designs should consider Cyclone-series replacements or check Altera/Intel end-of-life notices for last-time-buy windows.

典型應用
EP20K100FC144-1 適用於 6 應用s: Custom DSP Datapath Implementation, PCI Interface Bridge Logic, Telecommunications Glue Logic, Industrial Control Systems, Pre-ASIC Prototyping Platform, Legacy Equipment Maintenance and Repair.
Custom DSP Datapath Implementation
The EP20K100FC144-1's 4,160 logic elements and 53,248 bits of embedded RAM make it well suited for custom DSP datapaths in audio, video, and communications equipment. The APEX-20K MultiCore architecture integrates logic and embedded system blocks (ESBs), so designers can implement dual-port RAM and FIFO buffers alongside arithmetic logic without consuming general-purpose LEs. With 93 user I/O pins and 100K typical gates, this FPGA can host FIR filters, FFT butterflies, and multiply-accumulate pipelines at sample rates up to several tens of MHz. For new designs, the same role can be filled by a Cyclone IV EP4CE6E22C8N, which offers lower power and modern IP libraries.
推薦
PCI Interface Bridge Logic
The EP20K100FC144-1's 3.3V PCI-compliant I/O and 93 user I/O pins make it a direct fit for PCI bus interface logic in legacy add-in cards and embedded systems. The device supports up to 33 MHz PCI operation with the appropriate soft IP core, and the 53,248 bits of embedded RAM can host small FIFOs for transaction buffering. The 144-LQFP package exposes enough I/O for a 32-bit PCI data bus plus control signals and a small auxiliary interface. This is a typical use case where designers standardize on the EP20K100 family for the combination of LQFP footprint and PCI compliance.
推薦
Telecommunications Glue Logic
Telecommunications equipment often needs high-density glue logic to bridge between processors, ASICs, and physical interfaces, and the EP20K100FC144-1 fills this role with 100K typical gates in a 144-LQFP. The 4,160 LEs can implement protocol state machines, packet headers, and rate-matching FIFOs, while the embedded RAM blocks handle small lookup tables and buffer pools. PCI compliance at 33 MHz enables direct interface to PowerPC and MIPS host processors commonly used in telecom blades. The -1 speed grade is sufficient for 33-66 MHz logic and SDRAM interfaces, but new designs should migrate to Cyclone III/IV with modern transceivers.
推薦
Industrial Control Systems
Industrial controllers frequently need a flexible logic core that can be reconfigured for different sensor and actuator interfaces, and the EP20K100FC144-1 serves this purpose with 93 user I/O pins and 4,160 logic elements. Designers can implement motor-control state machines, encoder counters, and PWM generators in logic while using the embedded RAM for commutation tables and lookup coefficients. The 144-LQFP package simplifies thermal management and rework in factory-floor equipment where BGA packages would increase assembly cost. Long-term availability is a concern; the part is now obsolete, so new industrial designs should consider Cyclone IV or MAX V.
推薦
Pre-ASIC Prototyping Platform
Pre-silicon validation of an ASIC design is one of the strongest use cases for the EP20K100FC144-1, because the APEX-20K MultiCore architecture and abundant I/O let engineers prototype the entire ASIC RTL before committing to masks. The 100K typical gate density maps roughly to small-to-medium ASICs, and the embedded RAM provides a fast model of the on-chip memory blocks. Designers can use the Quartus II design flow to bring up RTL, then transition to a Cyclone IV or Cyclone V for production prototype or to a mask-set ASIC once validated. The 144-LQFP package fits standard 1.27 mm pitch prototype boards.
推薦
Legacy Equipment Maintenance and Repair
The EP20K100FC144-1 is most commonly sourced today for maintenance and repair of legacy equipment already in service in telecom, industrial, and medical systems. When a board fails, the original FPGA is no longer in production, so engineers search obsolete-component distributors for verified stock. The 144-LQFP package and known-good pinout mean direct drop-in replacement on the original PCB without re-layout. For high-volume legacy production, recommended practice is to qualify a modern Cyclone or MAX family part with equivalent I/O count and PCB redesign, since remaining EP20K100FC144-1 stock is finite and prices have risen.

設計說明
The EP20K100FC144-1 requires a 2.5V core supply (VCCINT) and a 3.3V I/O supply (VCCIO). Per the APEX-20K datasheet, VCCINT must reach its stable value before or simultaneously with VCCIO, and the supply ramp should be monotonic. Decoupling: place 0.1 uF ceramic capacitors within 5 mm of every VCCINT and VCCIO pin, plus bulk 10-100 uF tantalum or polymer capacitors near the package. Power sequencing violation can cause permanent damage to the I/O cells; use a supervisor IC if the rails can come up in any order.
LQFP-144 packages rely on copper pours for heat dissipation. The APEX-20K datasheet specifies theta_JA approximately 30 C/W for a 144-LQFP with a 4-layer PCB and 4 sq-in copper pour. At maximum core current (~500 mA at 2.5V), power dissipation is ~1.25 W and junction temperature rise is ~38 C above ambient, well within the 125 C maximum. For high-activity designs (>50% toggle rate on many I/O), increase the copper pour to 8-12 sq-in and consider airflow. Do not exceed the absolute maximum junction temperature of 150 C.
The 144-LQFP package has 0.5 mm pitch leads. PCB layout requires 0.2-0.25 mm trace-and-space rules for fanout and a 4-layer stack-up with continuous ground plane for the inner layers. Keep JTAG traces (TCK, TMS, TDI, TDO) short (<50 mm) and isolated from fast-switching I/O. Configuration pins (nCONFIG, nSTATUS, CONF_DONE) need a 4.7 kohm pull-up to VCCIO. Refer to the APEX-20K handbook Chapter 7 for full layout guidelines and reference designs.
Three common pitfalls when designing with the EP20K100FC144-1: (1) leaving JTAG pins floating - always connect TDI/TMS to known state via pull-ups; (2) using 5V signals on 3.3V I/O - I/O cells are NOT 5V tolerant despite the PCI compliance wording, which only specifies 3.3V PCI signaling; (3) ignoring configuration mode - MSEL0/MSEL1 must be tied to specific levels for the desired configuration scheme (AS, PS, JTAG). Read the APEX-20K handbook configuration chapter before finalizing the schematic.
