Typical Applications
EP20K100EQC208-3 is suitable for 6 applications: Industrial Control and Automation, Wired Networking and Protocol Bridging, Video and Image Processing, Test and Measurement Instrumentation, Telecom and Datacom Interface Cards, Embedded Prototyping and FPGA Learning Platform.
Industrial Control and Automation
The EP20K100EQC208-3 suits industrial PLC, motion-control, and factory-automation boards that need medium-density glue logic. Its 151 user I/O pins can capture parallel encoder inputs, drive simple actuator signals, and implement custom state machines without resorting to a large BGA FPGA. The 1.8 V core reduces switching power on dense 24/48 V industrial cards, while the 208-pin PQFP footprint remains routable on simpler four-layer PCB stacks. The 0°C to 85°C range covers most indoor industrial cabinets, but verify the application's ambient temperature before committing. If the design must operate below 0°C, expect to use a different temperature-grade part or add enclosure heating. Configuration can be loaded through an EPC2/EPC16 device at power-up, allowing firmware updates in the field via a serial configuration interface.
Recommended
Wired Networking and Protocol Bridging
For 10/100 Ethernet switch front ends, legacy TDM-to-packet bridges, and custom serialize/deserialize modules, the EP20K100EQC208-3 provides 4,160 logic elements for framing, FIFO control, and simple arbitration. Its 53,248 RAM bits buffer packets or hold descriptor tables, reducing external SRAM requirements. With 151 I/Os, this FPGA can connect to MAC/PHY devices, status LEDs, and a local host bus. Network timing often requires deterministic latency; because EP20K100EQC208-3 is SRAM-based, it must be configured before traffic starts. Use a serial configuration PROM and hold the FPGA in reset until CONF_DONE asserts. This architecture suits moderate-speed protocol conversion rather than high-end multi-gigabit routing, where dedicated transceivers would be required.
Recommended
Video and Image Processing
The EP20K100EQC208-3 can execute simple video timing generation, pixel format conversion, and line buffering for analog or low-resolution digital video paths. Its 53,248 RAM bits can hold a few full line buffers at VGA-class resolutions, enabling operations like horizontal scalers, edge detection, or chroma-key overlays. The 151 I/O pins connect to video ADCs/DACs, SRAM, and a microcontroller. Logic elements implement multiply-accumulate pipelines or shift registers at moderate clock rates. The -3 speed grade is usually adequate for 27 MHz or 74 MHz pixel clocks. Since video systems demand continuous operation, provide adequate power decoupling and ensure the EPC2/EPC16 configuration PROM is programmed with the correct bitstream. This FPGA is not suitable for ultra-HD 4K pixel processing without far larger logic and memory resources.
Recommended
Test and Measurement Instrumentation
Bench instruments, data loggers, and signal-conditioning modules often need flexible digital glue logic to interface ADCs, DACs, and host processors. The EP20K100EQC208-3 fits this role well because it combines 151 I/Os with embedded RAM in a QFP package. Designers can implement acquisition state machines, trigger logic, sample counters, and FIFO read/write controllers inside one FPGA. The 0°C to 85°C rating is acceptable for benchtop environments, while the 1.8 V core keeps heat manageable when the instrument is enclosed. Because this device is volatile, the instrument firmware should load the FPGA bitstream from a flash or a host processor immediately after power-on. For quick prototyping, a JTAG cable can configure the EP20K100EQC208-3 before production code is stored in an EPC2/EPC16 device.
Recommended
Telecom and Datacom Interface Cards
The EP20K100EQC208-3 is useful for line-card controller logic, HDLC framing, and channel mapping in legacy telecom equipment. With 151 user I/Os, designers can attach several serial TDM buses, status lines, and a microprocessor bus. Its 4,160 logic elements are sufficient for small state machines, per-channel counters, and alarm logic. The 53,248 RAM bits provide elastic buffering between asynchronous clock domains. The APEX-20KE 1.8 V core gives lower dynamic power than older 2.5 V PLD families, easing thermal design on densely populated interface cards. The QFP package is easier to inspect and rework than BGA alternatives, which is important for high-reliability legacy network hardware that may require manual field repair.
Recommended
Embedded Prototyping and FPGA Learning Platform
Because EP20K100EQC208-3 is available through older inventory and can be hand-soldered in a 208-pin PQFP, it is sometimes used in educational and evaluation boards for teaching FPGA design. The 151 I/O pins provide enough breadboard-accessible signals to connect switches, LEDs, DACs, and small displays. The 4,160 logic elements allow students to implement simple processors, state machines, and counters. The device is SRAM-based; using JTAG, learners can reconfigure it repeatedly without wearing out nonvolatile programming cells. EPC2/EPC16 can be added later to demonstrate a production-style configuration memory. This approach is attractive for low-speed 1.8 V logic instruction, but beginners should remember that the old APEX tool flow is distinct from current Intel Quartus support, so verify software compatibility before starting a course lab.

Key Differentiators

- Non-leaded finish for traditional tin-lead assembly (vs EP20K100EQC208-3N)
Design Notes
The EP20K100E is an SRAM-based FPGA, so the EP20K100EQC208-3 must be configured at every power-up. If the configuration device is missing or the CONF_DONE signal does not assert, the I/O pins remain in their pre-configuration state and the intended logic does not operate. Use an EPC2/EPC16 configuration device or drive configuration through JTAG. Follow the MSEL and mode-pin recommendations from the Intel/Altera APEX 20K configuration user guide for the chosen configuration scheme.
Use separate 1.8 V core and VCCIO supplies. Place 0.1 µF ceramic capacitors as close as possible to each VCC and VCCIO pin, plus a 10 µF bulk capacitor near the FPGA power entry. If I/O banks must interface to 3.3 V legacy logic, verify that the VCCIO setting is compatible with the applicable I/O standard. Applying 3.3 V to the 1.8 V core supply pin will damage the device, so double-check the regulator configuration before first power-up.
The 208-pin PQFP is a gull-wing package that can be hand-soldered, but for production volumes use a stencil and reflow profile recommended for QFP packages. Provide pad lands per the Altera/Intel package drawing, and consider adding test points on the configuration, JTAG, and clock pins for boundary-scan and in-circuit verification. Because this device has a 0°C to 85°C temperature rating, do not place it near high-power dissipating components without adequate airflow in elevated-temperature environments.
