Typical Applications
EP20K100FC324-2 is suitable for 6 applications: Telecom Interface Card Logic, Bus Bridging and Protocol Conversion, Industrial Control and PLC Backplane Logic, Legacy Datapath and DSP Glue Logic, Custom Peripheral Controllers, Test & Measurement Instrumentation Front-End.
Telecom Interface Card Logic
The EP20K100FC324-2 fits telecom interface cards because its 100K-gate capacity and 252 user I/Os support multi-protocol glue logic between line-side PHYs and a host ASIC. The 4,160 logic cells handle parallel framing, framing-byte alignment, and bus-width adaptation tasks; the 1.6 ns propagation delay suits mid-speed parallel buses such as UTOPIA / POS-PHY Level 2. Placed on the line-card with a dedicated 2.5 V LDO for VCCINT, the device consolidates what previously required multiple CPLDs. Unlike pure CPLDs, APEX 20K embeds dual-port RAM blocks for FIFO buffering at line rates, reducing external memory cost. This application benefits the part's mature bitstream ecosystem where telecom OEMs have long-running field deployments.
Recommended
Bus Bridging and Protocol Conversion
The EP20K100FC324-2's LUT-rich architecture and 252 I/Os make it a strong fit for bus-bridging designs that adapt between legacy parallel buses (PCI, VME, ISA) and modern high-speed interfaces. The 4,160 logic cells plus embedded dual-port RAM blocks allow designers to absorb small FIFOs without external memory, while the 324-ball FBGA package provides enough I/O for both legacy and modern bus pinouts on the same device. Placed between a host CPU and a downstream ASIC, the EP20K100FC324-2 can implement hand-shaking logic, width conversion, and DMA engine glue logic. Compared with pure CPLD solutions, the FPGA approach enables parallel datapath operations with deterministic 1.6 ns delays across distributed register-to-register paths.
Recommended
Industrial Control and PLC Backplane Logic
The EP20K100FC324-2 is well-suited for industrial control and PLC backplane logic, where its 252 I/Os can directly drive parallel backplane connectors, encoder inputs, and stepper-motor control signals. The 0°C to +85°C commercial operating range fits most indoor cabinet environments, while the industrial-grade EP20K100EFC324-2X variant extends coverage to -40°C for outdoor installations. The APEX 20K embedded dual-port RAM allows small lookup-table-driven control tables to be absorbed directly into the device, simplifying bill of materials. With a 2.5 V core supply and 1.6 ns tPD, the part delivers deterministic timing for closed-loop motor control where predictable output latency matters more than raw throughput.
Recommended
Legacy Datapath and DSP Glue Logic
The EP20K100FC324-2 fits legacy datapath designs where APEX 20K bitstreams are already deployed and need a manufacturing source. Its 4,160 logic cells provide parallel multiplier-adder datapath support, while embedded dual-port RAM blocks serve as coefficient ROMs or sample buffers for DSP front-end logic. The 200 MHz internal performance figure and 1.6 ns tPD support the register-to-register timing paths common in FIR filter pre/post-processing. Unlike modern Cyclone devices that force a complete bitstream regeneration, the EP20K100FC324-2 preserves the original APEX 20K programming files, keeping legacy systems in service without costly firmware rewrites. Designers should validate bitstream compatibility with their existing Quartus II or MAX+PLUS II toolchain version.
Recommended
Custom Peripheral Controllers
The EP20K100FC324-2 suits custom peripheral controllers where off-the-shelf microcontrollers lack sufficient parallel I/O bandwidth. Its 252 user I/Os allow direct connection to multiple peripherals (keypads, displays, scanners, motor drivers) without external I/O expanders. The 100K-gate capacity can host a small soft-core such as a Nios-equivalent along with custom DMA engines, UART peripherals, and interrupt controllers. Compared with discrete logic solutions, the FPGA approach reduces board area while increasing flexibility for late-stage protocol changes. Designers should pair the part with a configuration PROM (e.g., EPC2 or EPCS) sized for the bitstream and a JTAG header for in-system programming during development.
Recommended
Test & Measurement Instrumentation Front-End
The EP20K100FC324-2 fits test-and-measurement front-end designs needing deterministic parallel sampling logic, trigger routing, and protocol-aware stimulus generation. Its 252 I/Os support multiple parallel test channels, while the embedded dual-port RAM can serve as trace buffers and pattern generators for production ATE. The 1.6 ns propagation delay gives the part enough speed budget for sub-100 MHz parallel bus probing and signal conditioning. Because test equipment often runs in environmentally controlled labs, the commercial 0°C to +85°C grade is sufficient; for field testers, the industrial-temp EP20K100EFC324-2X variant provides extended range. Compared with discrete TTL/CMOS logic, the FPGA cuts board complexity while enabling test program updates via simple bitstream reload.

Key Differentiators
- Drop-in compatibility across -2 / -2X / -E speed grades (vs EP20K100FC324-1)
- Mature bitstream ecosystem (vs Generic CPLD (e.g., MAX V))
- Embedded dual-port RAM (ESB) blocks (vs Discrete logic + external SRAM)
Design Notes
The EP20K100FC324-2 requires a clean 2.5 V core supply and separate VCCIO rails (2.5 V or 3.3 V depending on I/O standard). Place 0.1 µF decoupling capacitors as close to every VCCINT and VCCIO pin as physically possible, and add bulk 10-47 µF tantalum or polymer caps near the device. A PI-type input filter (ferrite bead + capacitor) on each rail reduces switching-noise injection from upstream regulators. Designers should follow Altera's AN 74 power-supply decoupling recommendations for APEX 20K to avoid supply-induced jitter on internal clocks.
Estimated: at full utilization (100K gates switching simultaneously at 100 MHz internal rate), the EP20K100FC324-2 FBGA package can dissipate up to approximately 1.5-2 W into the PCB. Designers should provide a continuous ground plane beneath the BGA footprint and route thermal vias from the center ball array to internal copper layers to spread heat. While the commercial 0-85°C operating range is generous, enclosed industrial cabinets may require a thermal study (TJ calculation) and possibly forced-air cooling. Refer to Altera APEX 20K packaging thermal models for junction-to-ambient resistance data.
The 324-ball FBGA package uses 1.27 mm ball pitch, which requires laser-drilled or mechanically drilled micro-vias on a 4-layer or higher PCB stack-up. Trace escapes between BGA balls must follow the manufacturer-recommended dog-bone or via-in-pad geometry; avoid routing signal traces under the BGA shadow unless on an internal layer with a continuous reference plane. Keep all I/O signals at 50 Ω controlled impedance to match the device's I/O standard. Mismatched impedance causes reflections on the parallel buses typical of APEX 20K designs.
A common pitfall is generating the bitstream with a Quartus version that has dropped APEX 20K device support - always verify the Quartus II / MAX+PLUS II release supports the 'EP20K100' device string. Another pitfall is using the wrong configuration PROM (e.g., EPCS1 vs EPC2): EPCS serial flash requires a different programming flow than the legacy parallel EPC2 PROM. Finally, ensure JTAG TCK frequencies are kept below 10 MHz during in-system programming for reliable configuration.
