EP20K300EQI240-2X Overview
An FPGA is an integrated circuit whose internal logic fabric is configured after manufacturing, allowing hardware functions to be customized without a mask change. FPGAs fit within the hierarchy field-programmable gate array -> programmable logic device -> embedded semiconductor -> integrated circuit. This device also belongs to Altera's APEX 20K family, which was introduced as a system-on-a-programmable-chip platform and can integrate multiple logic, memory, and I/O functions in a single programmable device.
Key features of the EP20K300EQI240-2X include 11,520 logic elements arranged in 1,152 LABs/CLBs, 147,456 total RAM bits, and 152 user I/Os. The device provides 728,000 system gates, enough for complex state machines, interface controllers, and custom coprocessing functions. The 0.22 um CMOS process and 1.8 V core help reduce dynamic power compared with earlier 3.3 V or 5 V programmable logic. Archived listings also indicate a maximum internal frequency of 350 MHz and a propagation delay of 2.29 ns for the -2X speed variant, although final timing should always be verified from the device datasheet.
Because the APEX-20KE family uses Altera's MultiCore architecture, the EP20K300EQI240-2X merges look-up-table logic, embedded memory, and product-term functionality in one fabric. This architectural flexibility is useful in designs that combine control logic, data buffering, and register-heavy datapaths. The I/O count and gate density fit applications in telecommunications, industrial control, video capture, and development platforms where an off-the-shelf programmable device is preferred over a custom ASIC.
Typical applications include line-card protocol bridging, industrial machine controllers, medical instrument front ends, and early SOPC prototyping. The 152 user I/Os in the 240-pin package offer moderate interface width, sufficient for local busses, UARTs, SPI, and parallel control signals. For wider parallel data busses, a larger BGA version may be needed; however, this PQFP version is easier to hand-assemble and verify during prototyping.
When designing with the EP20K300EQI240-2X, pay attention to the 1.8 V core supply and separate I/O supplies. Use multiple decoupling capacitors close to each power pin, and confirm whether the design requires an industrial-temperature part because this I-grade variant is rated from -40C to 100C. Since the APEX-20KE family is obsolete, sourcing should be arranged through qualified distributors or verified brokers.

Typical Applications
EP20K300EQI240-2X is suitable for 6 applications: Telecommunications Line-Card Control and Protocol Bridging, Industrial Automation and Machine Control, Medical Instrumentation Front-End Processing, System-on-Programmable-Chip Development and Prototyping, Video and Image Processing, Aerospace and Defense Ruggedized Processing.
Telecommunications Line-Card Control and Protocol Bridging
The EP20K300EQI240-2X is well suited for line-card control, protocol translation, and packet-buffer management in telecom equipment. Its 11,520 logic elements and 147,456 RAM bits provide enough resources to implement FIFO buffering, CRC generation, and simple bridging engines without an external companion FPGA. The industrial temperature rating from -40C to 100C supports outdoor and uncontrolled-environment networking gear, where temperature swings can be severe. The 152 user I/Os are adequate for 8/16-bit local buses, status LEDs, and control handshakes. Designers should still decouple the 1.8 V core with multiple low-ESR ceramic capacitors to minimize switching noise and use the manufacturer's timing closure flow to verify that the -2 speed grade meets line-rate requirements.
Recommended
Industrial Automation and Machine Control
For industrial controllers, the EP20K300EQI240-2X can integrate motion-control state machines, encoder interface logic, and safety interlock logic in one programmable device. The 728,000-gate capacity and 152 I/Os allow connection to multiple sensors, relay drivers, and backplane signals. Because this I-grade part is rated for -40C to 100C, it can be placed in enclosures near motors, heaters, or unheated factory floors without requiring an extra heating stage. The APEX-20KE MultiCore architecture provides a balance of embedded RAM and register-rich lookup-table logic, making it useful for deterministic control loops. When used in retrofit or long-life industrial equipment, designers should consider the obsolete supply chain and qualify a second-source or stocked variant before committing to volume production.
Recommended
Medical Instrumentation Front-End Processing
The EP20K300EQI240-2X is suitable for medical instrumentation front ends where moderate logic integration and deterministic parallel processing are needed before a host processor. Its 147,456 RAM bits can buffer digitized samples and support DMA-style handshakes, while 11,520 logic elements implement filtering control, sequence timing, and communication protocol logic. The 1.8 V core lowers dynamic power in compact medical cards, simplifying thermal management in sealed enclosures. An industrial temperature range of -40C to 100C adds margin for sterilization or transport conditions, although medical equipment manufacturers must still perform their own biocompatibility and safety compliance testing. For lower-cost commercial systems, the same-family EQC240-2XN can be used if the 0C to 85C range is sufficient.
Recommended
System-on-Programmable-Chip Development and Prototyping
The EP20K300EQI240-2X is a good platform for system-on-a-programmable-chip prototyping because APEX-20KE devices were designed for SOPC integration with MultiCore architecture. Board-level developers can use 11,520 logic elements and 147,456 RAM bits to prototype a soft memory controller, custom bus bridge, or peripheral interface before committing to ASIC implementation. The 240-BFQFP package is more accessible for prototype soldering and rework than a high-pin-count BGA, making it attractive in university labs and early hardware validation. With a -2 speed grade and recommended airflow, internal frequencies around 350 MHz are often possible for small logic cones, but performance depends on placement, routing, and I/O standards. Because the device is obsolete, prototyping should include stock reservation for later production phases.
Recommended
Video and Image Processing
In video and image processing, the EP20K300EQI240-2X can implement line buffers, windowing logic, and simple pixel-processing chains before a host DSP or GPU. The 147,456 RAM bits support line storage and small image FIFOs, while the 11,520 logic elements can be configured for thresholding, edge detection, and format-conversion state machines. A 1.8 V core running at moderate clock rates helps minimize heat in compact machine-vision cameras and frame grabbers. Although higher resolution streams often require more RAM than this APEX-20KE device offers, it is adequate for VGA to early-SVGA resolutions and for test pattern generation. Use the 152 I/Os to connect parallel video buses, I2C control, and sync signals, and verify timing with the -2 speed grade. The industrial temperature option supports cameras mounted in production equipment.
Recommended
Aerospace and Defense Ruggedized Processing
The EP20K300EQI240-2X is a candidate for avionics and defense subassemblies that need programmable logic in a -40C to 100C environment. Its 728,000 gates and 152 user I/Os allow interfaces between legacy bus transceivers, sensor front ends, and a host processor. The 240-pin BFQFP package is more amenable than fine-pitch BGA to conformal coating inspection and manual rework, which is advantageous in low-volume defense production. Designers should be aware that APEX-20KE is not an AEC-Q100 or military-class device by default; radiation tolerance and extended-temperature screening were not documented in the captured data. A complete environmental qualification plan is required before deployment in airborne or weapon systems, and broker-sourced parts should be tested to ensure authentic die and date code.

Key Differentiators
- Industrial temperature range -40C to 100C (vs EP20K300EQC240-2XN)
- -2 speed grade in 240-BFQFP package (vs EP20K300EQC240-3N)
- 728,000-gate density in a 240-pin PQFP (vs EP20K300EQC240-3)
Design Notes
The EP20K300EQI240-2X core operates from 1.71 V to 1.89 V nominal 1.8 V. Place at least one 100 nF ceramic capacitor near every core power pin and at least one 10 uF bulk capacitor near the package edge. For large I/O banks, add separate local decoupling. Because no I/O supply voltage range was published in the captured data, verify the VCCIO pin requirement from the APEX-20KE datasheet before connecting external 2.5 V or 3.3 V logic.
Obsolete APEX-20KE FPGAs can dissipate several watts in heavily routed designs. With the 240-BFQFP package, provide a low-thermal-resistance PCB by using a solid ground plane, thermal vias beneath the package body if exposed-pad style is used, and moderate airflow. Estimated: if core current reaches 1.5 A at 1.8 V, core dissipation alone is about 2.7 W without I/O loading; use manufacturer power-estimation tools to determine actual thermal design.
The 240-lead BFQFP is a high-density gull-wing package that requires an accurate land pattern and stencil. Use a 0.4 mm to 0.5 mm aperture width recommendation from the datasheet and keep via fanout inside the package perimeter short. For prototype rework, expose the QFP body edge for inspection and provide test points on all power rails. Since the part is no longer in high-volume production, verify solderability and lead finish of each purchased lot before assembly.
Because the EP20K300E is obsolete, counterfeit and relabeled devices are a genuine sourcing risk. Purchase from authorized distributors or reputable brokers that can supply original date codes and test reports. Also confirm whether your board is RoHS-compatible: EP20K300EQI240-2X does not carry an N lead-free suffix in the captured data, but the EQC240-2XN variant is commonly specified as lead-free. Do not assume a package-only replacement is acceptable without verifying temperature grade and speed grade.
Compliance Information
The captured web data does not provide specific ROHS, REACH, or conflict-mineral compliance statements for EP20K300EQI240-2X. N-suffix variants such as EP20K300EQC240-2XN are commonly associated with lead-free finish but this should be confirmed from the manufacturer datasheet or distributor packaging details.
