Typical Applications
EP20K100EQC208-2 is suitable for 6 applications: Legacy Industrial Controller Upgrade, Telecom and Access-Network Bridging, High-Performance Computing Interface Logic, Test and Measurement Instrumentation, Networking Switch Fabric and Glue Logic, DSP and Data Acquisition Preprocessing.
Legacy Industrial Controller Upgrade
EP20K100EQC208-2 fits legacy industrial controller upgrades because its 151 user I/Os can monitor parallel buses, thumbwheel switches, and relay-driver logic while its 4,160 logic elements implement the required state machines. The 0°C to 85°C commercial range is acceptable for indoor PLC cabinets with forced-air or natural convection cooling. The on-chip 53,248 RAM bits create small FIFOs for alarm history without requiring external SRAM. Since the FPGA is SRAM-based, the board must include a configuration source such as an EPC device or microprocessor loader to program it after every power-up. When replacing an existing APEX 20K module, verify the original bitstream was compiled for a -2 speed grade; if it was, EP20K100EQC208-2 is the direct drop-in target.
Recommended
Telecom and Access-Network Bridging
Telecom line cards need flexible bridge and glue logic between framers, DSPs, and backplane buses. The EP20K100EQC208-2 provides 151 user I/O and 53,248 RAM bits for rate-matching FIFOs, while its 4,160 logic elements handle address decode, custom framing state machines, and backplane timing generation. Its 1.8 V core keeps logic power low in dense telecom racks, and the 0°C to 85°C range covers controlled central-office environments. Because the 208-BFQFP package uses gull-wing leads, solder joints remain inspectable, simplifying legacy telecom board repair. If a lead-free build is required after original tin-lead qualification, the EP20K100EQC208-2XN variant should be validated for solder-joint reliability and reflow profile.
Recommended
High-Performance Computing Interface Logic
In high-performance computing systems, EP20K100EQC208-2 can act as a flexible I/O hub between CPUs, DSPs, memory controllers, and mezzanine connectors. The FPGA's 151 user I/O pins allow numerous parallel or single-ended buses to be connected, while its 4,160 logic elements implement protocol converters, address interleaving, and handshake logic. The 53,248 RAM bits are useful for small FIFOs and mailbox registers between different clock domains. The -2 speed grade supports moderate-clock interface logic but is not intended for the fastest source-synchronous SerDes interfaces found in newer FPGAs. For legacy compute boards that already use a 208-PQFP APEX-20KE socket, EP20K100EQC208-2 offers a low-risk replacement without PCB changes.
Recommended
Test and Measurement Instrumentation
EP20K100EQC208-2 is well suited to test and measurement front ends that need flexible trigger logic, acquisition control, and instrument-bus interfacing. Its 4,160 logic elements can implement trigger state machines, timer/counter blocks, and calibration sequence controllers, while its 151 I/O pins connect to ADCs, DACs, front-panel controls, and host processor buses. The 53,248 RAM bits can store small acquisition buffers or histograms without tying up external memory. Commercial temperature operation is acceptable for benchtop and rack-mount instruments. The PQFP-208 package is easily reworkable, which is valuable during instrument prototype iterations. Existing firmware and configuration files developed for APEX-20KE -2 devices can generally be retained when using this part.
Recommended
Networking Switch Fabric and Glue Logic
EP20K100EQC208-2 provides a high I/O count suitable for small networking switch and router boards that need packet-buffer pointers, VLAN tag translation, and management-interface glue logic. The FPGA's 151 user I/O can connect to switch ASICs, PHYs, and control-plane microprocessors, while its 53,248 RAM bits are used for descriptor queues and port statistics. The 4,160 logic elements implement table-lookup state machines, CRC/error checking, and bus arbitration. At a 1.8 V core, the device consumes less power than many older 2.5 V FPGAs, making it compatible with legacy networking line-card power budgets. Because this is an SRAM FPGA, the configuration file must be held in a boot flash or configuration device on the line card.
Recommended
DSP and Data Acquisition Preprocessing
EP20K100EQC208-2 can preprocess sampled data before it reaches a DSP or microprocessor by implementing decimation filters, sample alignment, and channel sequencing logic. The 4,160 logic elements provide enough fabric for simple FIR address generators, 16-bit counters, and channel multiplexers; the 151 user I/O connect directly to high-speed ADCs, DACs, and processor buses. The 53,248 RAM bits are valuable for circular sample buffers and time-skew correction. The 1.8 V core supply keeps the FPGA section of a mixed-signal board manageable, and the 0°C to 85°C temperature range is conventional for laboratory data acquisition. When a legacy DSP board uses an APEX-20KE 208-PQFP device, replacing it with EP20K100EQC208-2 can avoid a PCB redesign.

Design Notes
EP20K100EQC208-2 uses a 1.8 V core supply, but the number of core power pins and the exact VCCINT current depend on the design's logic utilization, clock frequency, and I/O loading. Estimated: without board-level power data, use at least one 0.1 uF ceramic capacitor close to each VCCINT pin plus a bulk capacitor in the range of 10 uF to 47 uF per quadrant of the PQFP-208 package. Keep the 1.8 V regulator's sense trace short and stable during configuration surges. Verify the inrush current at power-up with the configuration device attached, because an unconfigured FPGA can transiently draw more current than during normal logic operation.
The 208-pin BFQFP package uses gull-wing leads on a square body. Fan out every lead to a via or test point during PCB layout so the part can be probed and reworked if an original legacy board is being replicated. Place the configuration interface header and the EPC/configuration memory close to the FPGA's dedicated configuration pins, and keep serial configuration traces short to avoid ringing. If this part is replacing an existing APEX-20KE 208-PQFP device, verify the footprint's pad size and thermal relief against the Altera recommended land pattern before committing to production.
Do not treat EP20K100EQC208-2 as a power-on-ready logic device; it is SRAM-based and must receive a configuration bitstream after every power-up. A common failure is designing a board with no configuration device, leaving the FPGA I/O pins in an undefined state until an external host loads them. Ensure the configuration voltage levels are compatible with the selected configuration source and that the reset and nCONFIG signals are properly terminated. Because APEX 20K is a legacy family, avoid assuming that a current FPGA development tool still has complete device support; use the last Altera tool version that supports APEX-20KE and lock the configuration settings.
Compliance Information
No RoHS/lead-finish statement was captured for the base -2 order code. The N/XN suffix variants are commonly used to indicate lead-free finish on Altera devices; confirm the exact marking and manufacturer statement before requiring RoHS compliance.
