An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that engineers can re-program in the field to implement arbitrary digital logic, glue logic, DSP pipelines, or even full soft processors. FPGAs occupy the upper tier of the programmable logic hierarchy (FPGA > CPLD > SPLD > PAL/GAL) and are widely used for prototyping ASICs, low-volume custom compute, hardware-accelerated signal processing, and interface bridging. The APEX 20K family was notable for introducing MultiCore™ embedded system blocks, allowing on-chip integration of dual-port RAM, CAM, or ROM.
Key features of the EP20K100QI240-2 include 4,160 logic elements, 53,248 RAM bits, 189 user I/Os, propagation delay of approximately 1.6 ns, a maximum internal frequency of 200 MHz, and 4 dedicated inputs plus 4 global clocks. The 2.5 V core (with 3.3 V PCI-compliant I/O tolerance on selected banks) and 0.22 µm CMOS process deliver industry-leading density for its generation.
Architecturally, the device integrates Look-Up Table (LUT) logic, product-term logic, and embedded memory in a single MultiCore fabric - a hybrid scheme that lets the designer place register-intensive datapaths in LUTs while implementing fast control logic in product terms. This MultiCore approach, combined with True-LVDS and PLLs, made APEX 20K a popular choice for high-speed telecom and DSP backplanes in the late 1990s and early 2000s.
Typical applications include digital signal processing (DSP) front-ends, telecom protocol bridging, custom peripheral controllers for embedded systems, image-processing pipelines, and industrial control glue logic. The 189 user I/Os make it suitable for wide parallel buses connecting microprocessors, memory, and analog front ends.
When designing with the EP20K100QI240-2, engineers should note that this device is part of the mature APEX 20K family and is recommended only for legacy maintenance and existing design support; new designs should target Cyclone, Arria, or Stratix families. Quartus II design software (legacy versions) is required for place-and-route.
This page synthesizes distributor pricing, drop-in same-package alternatives within the APEX 20K family, and practical design notes not consolidated in the manufacturer datasheet, giving engineers a single reference for sourcing and second-sourcing decisions.

典型應用
EP20K100QI240-2 適用於 6 應用s: Telecom Protocol Bridging, Legacy Industrial Control Glue Logic, DSP Front-End Pre-Processing, Custom Peripheral Controller, Test & Measurement Instrumentation, Legacy Aerospace/Defense Avionics.
Telecom Protocol Bridging
The EP20K100QI240-2 fits telecom protocol bridging because its 4,160 logic elements and 53,248 bits of embedded RAM can implement multi-protocol state machines and small FIFOs, while 189 user I/Os handle wide parallel bus conversion between legacy TDM/E1 framer ASICs and modern microprocessors. The 200 MHz internal clock supports bit-rate adaptation up to STS-3/STM-1 line rates when paired with external serializer/deserializer chips. MultiCore architecture lets designers co-locate product-term control logic next to LUT-based datapath logic, reducing routing congestion on dense bridging designs.
推薦
Legacy Industrial Control Glue Logic
The EP20K100QI240-2 is well-suited for industrial control glue logic that bridges sensors, motor encoders, and actuator drivers to PLCs or industrial PCs. Its 189 user I/Os handle wide parallel buses to legacy ISA-style peripherals, while the 53 Kbits of embedded RAM implement small lookup tables for PID coefficients or waveform generation. The PQFP package is straightforward to hand-rework for low-volume industrial maintenance work. Designers should verify industrial temperature grade and provide external watchdog timers since the APEX 20K has no built-in hardware watchdog.
推薦
DSP Front-End Pre-Processing
The EP20K100QI240-2 is appropriate for DSP front-end pre-processing tasks like FIR filtering, FFT pre-staging, and image preprocessing where the 4,160 logic elements can implement the datapath while the embedded RAM blocks (ESBs) hold coefficient tables. The 200 MHz internal clock supports real-time preprocessing of video or audio streams before handoff to a DSP or ASIC. MultiCore architecture accelerates parallel arithmetic by allowing co-located product-term logic for control alongside LUT-based multipliers.
推薦
Custom Peripheral Controller
The EP20K100QI240-2 can implement a custom peripheral controller where standard microcontrollers lack the required I/O count or timing flexibility. The 189 user I/Os allow direct connection to multiple peripherals including memory buses, parallel ADCs, DACs, and custom ASICs. Embedded RAM supports small command queues and DMA descriptors, while the 4,160 logic elements handle protocol state machines. The PQFP package is preferred over BGA for hand-rework in low-volume aerospace/defense maintenance programs.
推薦
Test & Measurement Instrumentation
The EP20K100QI240-2 supports legacy test and measurement instruments such as protocol analyzers, logic analyzer probe heads, and pattern generators where custom timing is required. The 200 MHz internal clock combined with programmable I/O delay chains allows precise generation and capture of digital waveforms. The MultiCore architecture simplifies integration of state machines, counters, and data path logic in a single device. Engineers should note that real-time test equipment benefits from the dedicated global clocks for low-skew distribution.
推薦
Legacy Aerospace/Defense Avionics
The EP20K100QI240-2 is used in legacy aerospace and defense avionics where the design was qualified years ago and field maintenance requires drop-in replacements. MultiCore architecture and PQFP package are advantageous for high-reliability through-hole-like rework in depot-level repair facilities. Designers must verify whether the application requires a QML or military temperature grade; the standard EP20K100QI240-2 supports the 0-85 °C commercial range only. For new aerospace programs, use radiation-tolerant Microsemi/RTAX or modern Cyclone-based boards.

主要差異化特點
- MultiCore architecture combining LUT, product-term, and embedded memory (對比Discrete PAL + SRAM implementations)
- 189 user I/Os in PQFP for hand-reworkability (對比BGA-package FPGAs with same logic capacity (e.g., EP20K100FC324-2))
- 4 dedicated inputs and 4 global clocks with low-skew distribution (對比Software-only clock trees in smaller CPLDs)
設計說明
Estimated: APEX 20K EP20K100 devices consume approximately 200 mA to 600 mA from the 2.5 V VCCINT rail depending on toggle rate and utilization of the MultiCore ESB blocks. Provide a low-noise 2.5 V linear regulator (e.g., LT1963 or TPS7A45) with at least 20% headroom. The 3.3 V VCCIO rail may source up to 1 A depending on I/O switching; place 0.1 µF decoupling caps on every VCCINT and VCCIO pin pair plus a single 47 µF bulk cap adjacent to the package.
The 240-pin PQFP uses a 1.27 mm pin pitch with gull-wing leads - route a 4-layer PCB with dedicated ground and power planes. Keep all 240 traces short and matched for clock and high-speed I/O signals; the recommended trace impedance is 50 Ω single-ended. For the global clock pins (CLK0-CLK3), use matched-length routing from the clock source to minimize skew. Add 22 Ω series termination on outputs driving long external cables or backplane connectors.
Configuration bitstream must be loaded from a serial configuration device (EPC2, EPC4, EPC8, EPC16) or via JTAG; do NOT assume the device powers up in user mode. The APEX 20K family does NOT support passive or pull-up based configuration. Always include a JTAG header (TCK, TMS, TDI, TDO, TRST, VCC, GND) on the PCB for in-system programming and boundary-scan test. Also note: bitstreams are not portable across speed grades - changing -2 to -3 or -1 requires recompilation.
Estimated: The 240-pin PQFP has a θJA of approximately 25 °C/W still air; at full 200 MHz operation and 80% utilization the device may dissipate 1.5 W to 2 W, yielding a 50 °C junction temperature rise above 25 °C ambient. For commercial 0-85 °C operation this is acceptable, but for enclosed industrial enclosures provide at least 100 cm² of copper pour on top of the PQFP thermal pad area to reduce θJA to 18 °C/W.
合規資訊
Per Partstack data, the EP20K100QI240-2 uses Tin-Lead (SnPb) terminal finish, indicating it is NOT lead-free / RoHS compliant by default. The Pb-free variants have an X suffix (e.g., EP20K100QC240-1X, EP20K100QC240-3N). AEC-Q100 not applicable - FPGAs do not carry this automotive qualification; users must qualify the system at the board level. RoHS / REACH / conflict minerals compliance data not available in provided sources - engineers should request the latest material declaration directly from Intel.
