Typical Applications
EP20K100CQ240C7ES is suitable for 6 applications: Telecommunications Line Cards, Industrial Control and Factory Automation, PCI Bridge and Legacy Bus Interface, Military and Aerospace Signal Processing, ASIC Prototyping and System-on-Chip Validation, Medical Imaging Front-End Processing.
Telecommunications Line Cards
The EP20K100CQ240C7ES is well-suited for telecom line-card glue logic where 100K gates of deterministic LUT-based logic and 189 I/O provide ample capacity for TDM bus aggregation, channelized framing, and protocol adaptation. Its MultiVolt I/O banks directly interface to 5V legacy backplanes and 3.3V framers without level shifters, while the embedded array blocks (EABs) implement small FIFOs and lookup tables that previously required external SRAM. The -7 speed grade comfortably meets typical 50 MHz telecom backplane timing, and 5V tolerance enables hot-swap line-card insertion. Companion timing devices from the Site MPN list (e.g., EPC2 configuration PROMs and 8T49N285 PLL clock generators) complete a typical line-card reference design.
Recommended
Industrial Control and Factory Automation
In factory automation PLCs and motor controllers, the EP20K100CQ240C7ES provides deterministic state-machine logic with 4,160 LEs sufficient for PID loops, encoder quadrature decoders, and CAN/DeviceNet protocol stacks. The 189 I/O accommodate high-channel-count digital I/O cards and the MultiVolt I/O banks accept 24V-tolerant signals via external resistor dividers. Industrial users typically specify the F-grade (industrial temperature) variants such as EP20K100CF324C7 for -40C to +85C environments; the EP20K100CQ240C7ES commercial-grade counterpart suits factory-floor control panels where ambient is controlled. The 0.22 µm CMOS process has demonstrated field reliability across two decades of industrial deployments.
Recommended
PCI Bridge and Legacy Bus Interface
The EP20K100CQ240C7ES has historically been a popular PCI bridge FPGA because the 100K-gate capacity fits a 32-bit/33 MHz PCI target or master state machine plus DMA engine in a single device without external glue logic. The 189 I/O easily accommodate the 49-pin PCI bus (AD[31:0], C/BE#[3:0], FRAME#, IRDY#, TRDY#, etc.) plus 5V signaling tolerance, enabling direct connection to PCI 5V slots without bus switches. Designers implementing custom ASIC replacements or post-PCIe migration boards still benefit from the APEX20K MultiCore architecture when designing drop-in PCI add-in cards for legacy systems. PCI-X and 66 MHz variants require the -8 or -9 speed grade.
Recommended
Military and Aerospace Signal Processing
Defense and aerospace programs adopted the APEX20K family extensively during the 2000s for radar signal pre-processing, sonar beamforming, and avionics databus interfaces. The EP20K100CQ240C7ES specifically served cost-sensitive commercial-grade subsystems where MIL-STD-810 environmental qualification was performed at the system level rather than the component level. Today, these programs face obsolescence risk and use the EP20K100CQ240C7ES only in sustainment-phase manufacturing, with design refreshes typically migrating to radiation-tolerant FPGAs such as Xilinx Virtex-4QV or Microsemi RTG4. Designers should consult the Defense Logistics Agency for long-term supply contracts on APEX20K-based legacy designs.
Recommended
ASIC Prototyping and System-on-Chip Validation
ASIC prototyping teams historically chose the EP20K100CQ240C7ES as a mid-density vehicle to validate logic IP blocks before tape-out, partitioning the design across multiple APEX20K devices for full-chip ASIC prototyping. Its 53,248 bits of embedded RAM distributed across EABs can map ASIC register files and small cache memories, while the FastTrack continuous routing network provides predictable timing that simplifies static timing analysis of the prototype. Modern prototyping flows have largely migrated to Cyclone V or Virtex-7 FPGAs offering 10x the density, but APEX20K-based emulators remain in service at companies with sunk toolchain investment. For new prototyping, the EP20K100CQ240C7ES is no longer cost-effective.
Recommended
Medical Imaging Front-End Processing
Medical imaging modalities such as ultrasound and endoscopy systems adopted APEX20K FPGAs in the early 2000s for beamforming, image preprocessing, and display timing generation. The EP20K100CQ240C7ES provides the 100K-gate logic density appropriate for channel preprocessing in mid-range ultrasound carts, and the MultiVolt I/O directly interfaces to 5V ADC front-ends and LVDS image sensors. Its deterministic FastTrack routing simplifies the timing closure required for real-time beamforming pipelines. For new medical designs, IEC 62304 and ISO 13485 documentation trails require active-lifecycle components, so designers should select the active Cyclone IV EP4CE40F23 or Cyclone V 5CEBA4F23 instead, using APEX20K only for sustaining engineering of legacy installed bases.

Design Notes
The EP20K100CQ240C7ES requires two independent power rails: a 2.5V VCCINT for the core and a per-bank VCCIO that can be 1.8V, 2.5V, 3.3V, or 5.0V. According to the APEX20K handbook, the device draws approximately 200-500 mA on VCCINT depending on toggle rate and utilization. Decouple each VCC/VSS pair with a 0.1 µF X7R ceramic plus a 47 µF bulk tantalum near the package. Power sequencing is not critical: VCCINT may ramp before or after VCCIO without damage. Estimated: at 100% utilization toggling at 100 MHz, ICCINT may reach 800 mA; verify with PowerPlay early-board estimator before final layout.
Route all configuration and JTAG signals (TCK, TMS, TDI, TDO, nSTATUS, CONFIG_DONE, nCONFIG) with 50Ω controlled impedance and avoid stubs. Place the EPC2/EPC16 configuration PROM within 100 mm of the FPGA to minimize signal-integrity issues on the serial DCLK and DATAO lines. The 240-PQFP package has a 0.5 mm pitch; use 0.20 mm wide traces and 0.20 mm spacing with microvia-in-pad PCB technology if available, otherwise a 4-layer stackup with continuous power/ground planes is mandatory to manage simultaneous switching noise across 189 I/O.
Common pitfalls when designing with the EP20K100CQ240C7ES include: (1) failing to pull nCONFIG high through a 1-10 kΩ resistor to VCCIO (a floating nCONFIG can cause spurious reconfiguration); (2) leaving the JTAG chain un-buffered in multi-FPGA boards (chain integrity issues become unmanageable); (3) using Quartus II software newer than 13.0sp1 (the APEX20K family is no longer supported in Quartus Prime); and (4) using 5V input signals without confirming 5V tolerance on each I/O bank via the datasheet's VIL/VIH table - older PQFP revisions had banks that were NOT 5V-tolerant.
Estimated: the 240-PQFP package has θJA of approximately 35 °C/W with 0 m/s airflow, rising to 25 °C/W at 1 m/s. At typical commercial-temperature dissipation of 1-2 W, junction temperature rise is 25-50 °C above ambient, well within the 125 °C Tjmax. However, in enclosed industrial enclosures with no airflow and 100% utilization, dissipation can exceed 3 W and the device should be mounted with thermal vias under the exposed die-attach pad (PQFP does not have an exposed pad; use a copper-flooded topside pour connected to GND via thermal vias to reduce θJA).
Because the APEX20K uses continuous FastTrack interconnect, intra-FPGA timing is deterministic and not subject to routing-dependent variability. However, board-level signal integrity still requires SSN (simultaneous switching noise) analysis when driving 32+ I/O simultaneously. Use a 22 Ω series resistor on each output driving long backplane traces, and add 47 pF EMI caps on clock outputs to slow edge rates below 2 ns/V where EMI regulations apply. Clock inputs should use the PLL in zero-delay buffer mode to eliminate on-board clock-to-clock skew across multiple FPGAs.
Compliance Information
RoHS and lead-free status could not be confirmed from the provided web data; the APEX20K family predates Intel's formal RoHS-6 transition in 2006. The ES suffix typically indicates enhanced-screening commercial-temperature parts rather than lead-free finish. Consult Intel's PCN archive or original datasheet amendment for definitive compliance statements.
