EP20K100QI240-2V Overview
A field-programmable gate array is a programmable logic device whose logic function is defined after manufacturing by loading a configuration bitstream. In the FPGA hierarchy, the EP20K100 is a mid-density 100K-gate device that sits below million-gate FPGAs but above simple CPLDs. Altera introduced the APEX 20K family with a MultiCore architecture that integrates look-up table (LUT) logic, product-term logic, and embedded memory blocks onto one device, making it suitable for system-on-a-programmable-chip designs.
Key features from the captured listings include 100K gates, 4,160 logic elements/cells, 200 MHz internal frequency, 189 user I/O lines, 4 dedicated inputs, 53,248 RAM bits, and a nominal 2.5 V core supply with an operating range of 2.375 V to 2.625 V. The 240-pin PQFP package is identified as 240-BFQFP on distributor pages, and the part is built on a 0.22 um CMOS process.
From an architecture perspective, the APEX 20K MultiCore fabric combines LUT-based logic for register-intensive functions, product-term logic for wide combinatorial functions, and embedded memory for FIFOs and RAM. These heterogeneous resources let the EP20K100QI240-2V perform tasks that would otherwise require multiple devices or an external controller. Because it is SRAM-based, the FPGA must be configured after power-up from an external nonvolatile source such as an EPC2 or EPC16 configuration device.
The EP20K100QI240-2V is most practical in legacy telecom line cards, industrial control boards, test instruments, and broadcast or audio/video infrastructure where the existing PCB footprint and FPGA support already exist. The 189 I/O lines are sufficient for bus translation, simple FIFO interfacing, and glue logic, while the 2.5 V core reduces supply complexity compared with earlier 5 V programmable logic.
For board bring-up, keep the core supply between 2.375 V and 2.625 V and decouple each supply region with ceramic capacitors. Connect the configuration device pins to standard APEX20K configuration signals and verify that the nCONFIG, nSTATUS, and CONF_DONE pins are pulled correctly. Since this FPGA is legacy, thoroughly screen date code and test samples before production use.

Typical Applications
EP20K100QI240-2V is suitable for 6 applications: Legacy Telecom Line Card Bridging, Industrial PLC I/O Module, Broadcast Video and Audio Infrastructure, Test and Measurement Instrumentation, Data Acquisition and Sensor Processing, Legacy BOM Sustainment and Board Repair.
Legacy Telecom Line Card Bridging
EP20K100QI240-2V works well in legacy telecom line cards where a proven 2.5 V FPGA is used to bridge serial TDM buses, small packet FIFOs, or backplane interfaces. Its 189 user I/O provide enough pins for multiple bus-wide data paths, while 53,248 RAM bits build small FIFOs and cell buffers without external memory. The 200 MHz internal clock is adequate for T1/E1 and lower-rate OC-3 aggregate designs when routing is planned carefully. The LUT-plus-product-term MultiCore fabric efficiently implements protocol decoders, HDLC controllers, and simple state machines. Place the APEX20K near the framer, use a clean 2.5 V supply, and configure the device from an EPC2 or EPC16 nonvolatile device. Trade-off: the 0.22 um process consumes more power than modern FPGAs, but this device remains practical for legacy board sustainment.
Recommended
Industrial PLC I/O Module
For industrial controllers that need to interface a host CPU bus to optocoupled input/output channels, EP20K100QI240-2V provides abundant logic and enough I/O to decode addresses, debounce inputs, and generate output strobes. The QI suffix in the part number indicates the industrial ordering family used in extended-temperature equipment, which is important for PLC racks installed in factory environments. The 2.5 V core should be derived from an isolated DC-DC converter and decoupled close to the FPGA package. Product-term logic in the MultiCore architecture is well suited to wide address decoders and combinatorial handshake logic. Although the 200 MHz maximum frequency is far above the typical 10-50 MHz PLC bus speed, the real benefit is the high I/O count and predictable 3.3 V or 2.5 V I/O compatibility when properly configured.
Recommended
Broadcast Video and Audio Infrastructure
In broadcast routing switchers and audio embedder boards, EP20K100QI240-2V can handle sub-frame synchronization, audio packet packing, and simple video timing logic when paired with external deserializers. Its embedded RAM blocks are useful for small line buffers and audio FIFOs, reducing external memory chip count. The 200 MHz internal clock supports SDI-related logic operating below 270 MHz when pipelined carefully, but the designer should not expect modern 3G-SDI or 12G-SDI serial rates directly on the FPGA fabric without external SERDES. The 189 I/O lines are enough to connect to multiple ADC/DAC devices, host microcontrollers, and configuration EEPROMs. For legacy broadcast equipment maintenance, this FPGA provides a drop-in-compatible logic family with familiar Altera tool flow support.
Recommended
Test and Measurement Instrumentation
EP20K100QI240-2V is suitable for test and measurement equipment that needs pattern generation, trigger logic, and custom bus timing. The 4 dedicated input pins can be assigned to asynchronous triggers or global clock distribution, while the 189 user I/O lines connect to DACs, ADCs, front-panel buttons, and display interfaces. Embedded memory blocks create capture buffers for transient waveforms and logic-analyzer applications. The 200 MHz internal operating capability enables fast state machines and high-speed counter designs. Instrument designers should pay attention to power-supply cleanliness because the 0.22 um 2.5 V core is sensitive to supply noise. For legacy ATE or lab instruments already using APEX20K devices, this part offers a straightforward replacement path without changing the PCB.
Recommended
Data Acquisition and Sensor Processing
In multi-channel data acquisition systems, EP20K100QI240-2V can pre-process sensor data, implement digital filters, and generate timing signals for analog-to-digital converters. Its 4,160 logic elements are enough for simple FIR filters and multiplexers, while the embedded memory blocks act as circular buffers for streaming data. The 189 I/O lines allow parallel connection to 16-bit or 32-bit ADCs and DACs without excessive pin sharing. The 2.5 V core keeps logic power lower than older 5 V programmable logic, reducing heat inside densely packed instrument enclosures. However, designers must ensure that the ADC digital interface voltage matches the configured FPGA I/O standard. For existing APEX20K-based data acquisition cards, this MPN provides a practical drop-in option during legacy maintenance.
Recommended
Legacy BOM Sustainment and Board Repair
The most common use of EP20K100QI240-2V today is sustaining products that were originally designed with APEX20K FPGAs. Because the part uses a 240-pin PQFP package, PCB layouts from the early 2000s can be populated with equivalent suffix variants without a board redesign. The QI ordering suffix indicates the industrial-grade family, and the -2 speed grade matches many legacy designs. When carrying out repair, confirm the exact firmware bitstream and configuration method used by the original product. EPC2 or EPC16 configuration devices should be checked and reprogrammed if necessary. Buyers should also screen for counterfeit or relabeled devices by testing date code, marking, and functional operation before inserting parts into expensive systems.

Design Notes
Use a dedicated 2.5 V power plane for the core and keep the input source within the 2.375 V to 2.625 V range found in the Microchip USA listing. Legacy APEX20K devices made on 0.22 um CMOS can draw significant dynamic current on large designs, so place at least one 0.1 uF ceramic capacitor close to each power pin group and add a 10 uF bulk capacitor near the PQFP body. If the power supply is shared with noisy digital logic, add a ferrite bead between the main rail and the FPGA VCC pin bank. Verify the actual current draw using the Quartus power estimator or by measuring a prototype board before finalizing regulator sizing.
The EP20K100QI240-2V is SRAM-based and loses its configuration when power is removed. Use an EPC2 or EPC16 configuration device, or configure the FPGA from a host processor through ITAG or passive serial mode. In a typical APEX20K board, confirm nCONFIG, nSTATUS, and CONF_DONE are connected with appropriate pull-up resistors. The configuration device should be programmed with the same bitstream revision used on the original board, and the design should be re-verified after any change in speed grade or package variant. Treat configuration failure as the most common cause of blank or non-functional APEX20K boards.
The 240-pin PQFP package has leads on four sides and no exposed center pad in the standard package drawing, so heat is removed mainly through the lead frame and PCB copper. When the FPGA is heavily utilized, provide forced airflow across the package and connect the thermal vias under the body to a ground plane if the package drawing permits. Estimate the junction temperature using the package thermal resistance from the APEX20K datasheet; the datasheet is the authoritative source for theta-JA. For legacy industrial designs, keep enough margin below the maximum junction temperature to ensure reliable operation in high ambient conditions.
Route 200 MHz-capable clock nets with controlled impedance and minimize via count on the clock path. Because the APEX20K is a large 240-lead package, fanout all signal pins to the inner layers before connecting to dense connector fields. Separate the configuration clock and data lines from high-speed parallel signals to avoid glitches during configuration. Use ground vias adjacent to each high-speed output to reduce return-current discontinuity. When creating the PCB footprint, confirm the package drawing from the datasheet because BFQFP and PQFP names are used interchangeably for the same 240-pin body.
Check the exact suffix of the part before assembly: EP20K100QI240-2V, EP20K100QI240-2N, and EP20K100QI240-2 are all similar 240-pin PQFP parts but may differ in finish, code, or temperature ordering. Because APEX20K is legacy, obtain parts only from reputable sources and verify date code, top mark, and functionality. If a board has been stored for years, reprogram the configuration device and perform a full JTAG boundary-scan test before installing the FPGA in production. Never mix a -3 speed-grade part into a design that was timing-closed for -2 without repeating timing analysis.
Compliance Information
The captured search data does not state RoHS, REACH, halogen-free, or conflict-mineral status for EP20K100QI240-2V. The N suffix on related APEX20K parts often indicates lead-free, but formal compliance must be confirmed from the Altera/Intel datasheet or packaging specification.
