Typical Applications
EP20K100CF324C8 is suitable for 6 applications: Telecommunications Line Card Interface, Industrial Automation Controller, Legacy Networking Bridge / Router Glue Logic, PCI / CPCI Interface Adapter, Video Processing Pre/Post-Processor, Medical Imaging Data Acquisition Front-End.
Telecommunications Line Card Interface
The EP20K100CF324C8's 4,160 logic elements and 246 user I/O pins make it well-suited for telecom line cards implementing TDM bus bridges, framer interfaces, and HDLC controllers. Its 53,248 bits of embedded RAM via 26 ESBs allow on-chip buffering of E1/T1 payload data without external SRAM. Designers can implement UTOPIA, POS-PHY, or serial telecom protocols at moderate line rates, with the 1.8 V core consuming less than 1 W typical power. The 324-FBGA package fits standard ATCA/AMC board assemblies.
Recommended
Industrial Automation Controller
In industrial PLC and motion-control applications, the EP20K100CF324C8 provides the logic density for servo-loop calculation, encoder interface logic, and fieldbus bridges (Profibus, DeviceNet, CANopen). Its 0°C to +85°C commercial temperature range suits factory-floor enclosures, while the 246 I/O pins handle multiple encoder inputs and parallel DAC interfaces. The embedded RAM blocks implement position-lookup tables and PID coefficient storage, eliminating external memory. JTAG-based in-system programming simplifies firmware updates on deployed controllers.
Recommended
Legacy Networking Bridge / Router Glue Logic
The EP20K100CF324C8 is widely deployed as glue logic in legacy routers, bridges, and ATM switches where it handles PCI bus arbitration, memory controller interfacing, and protocol encapsulation. The 53,248-bit embedded memory serves as packet-buffer head/tail pointers and routing-table caches, while the 4,160 LEs implement stateful packet inspection. Network equipment manufacturers chose this part for its low power, JTAG-based field upgrade capability, and proven long-term reliability in carrier-grade environments.
Recommended
PCI / CPCI Interface Adapter
The EP20K100CF324C8 integrates seamlessly as a PCI bus target/master interface controller, providing the 33 MHz PCI protocol state machine, configuration space registers, and bus arbiter glue logic. Its 246 user I/O pins handle the 32-bit multiplexed PCI address/data bus plus auxiliary peripheral interfaces. Embedded RAM blocks implement the 16 DWORD write FIFO and read prefetch buffer required by PCI burst transfers. This application is common in industrial PCs, medical imaging cards, and military CPCI backplanes.
Recommended
Video Processing Pre/Post-Processor
Broadcast video equipment historically used the EP20K100CF324C8 to implement format converters, genlocking circuits, and timing generators for SDI streams. The 53,248 bits of embedded RAM serve as line buffers for horizontal and vertical scaling, while the 4,160 logic elements handle sync insertion and color-space conversion matrices. The 246 I/O pins accept multiple parallel video buses plus audio embedding channels. While not suited for HD-SDI at full rate, it remains appropriate for SD-SDI and composite video processing.
Recommended
Medical Imaging Data Acquisition Front-End
Ultrasound and endoscopy systems used the EP20K100CF324C8 as a front-end data acquisition controller, digitizing analog sensor arrays and performing beamforming preprocessing. Its parallel I/O capability accepts 16-bit ADC data at 40 MSPS, while the embedded RAM implements delay-line buffers for phased-array beamforming. The JTAG interface allows field updates to imaging algorithms. Although newer medical devices have migrated to Cyclone or Stratix families, the EP20K100CF324C8 remains in certified legacy equipment due to FDA re-validation costs.

Key Differentiators
- Mid-range 100K-gate APEX-20K with 246 I/O (vs EP20K100CF324C7)
- 324-ball FineLine BGA footprint (vs EP20K100CB356C8)
- Extended temperature screening available (vs EP20K100CF324C7)
Design Notes
Estimated: At 1.8 V core with 4,160 LEs at typical 50% utilization and 100 MHz internal clock, core current is approximately 200 mA, dissipating 360 mW. Add 50 mA per VCCIO bank at full switching, totaling ~150 mW I/O. Place 0.1 µF X7R ceramic capacitors within 5 mm of every VCCINT and VCCIO pin, plus a 47 µF tantalum bulk capacitor at the regulator output. Power sequencing should ensure VCCINT ramps before VCCIO.
The 324-FBGA has 1.0 mm ball pitch requiring 4-layer or 6-layer PCB with microvia or laser-drilled via-in-pad for escape routing. Fanout should use dog-bone or via-in-pad patterns with 0.5 mm via diameter. Maintain 50 Ω controlled impedance on clock and high-speed I/O traces. Avoid routing signals beneath the BGA shadow area; place decoupling capacitors on the opposite PCB side or in the breakout region.
Do not assume modern Intel Quartus Prime supports the APEX-20K family - it does not. Use Quartus II version 13.0 or earlier. JTAG programmer must support 1.8 V VCCIO during configuration; older ByteBlasterMV cables may require a 74LS244 or similar buffer for 1.8 V tolerance. Verify all I/O bank voltage assignments before generating the programming file, since incorrect VCCIO can permanently damage the device.
Differential pairs (LVDS, though limited on APEX-20K) should be length-matched within 150 mil. SSTL Class II memories require external 25 Ω series termination resistors at the FPGA output. Place the JTAG chain in a daisy-chain configuration with TMS and TCK pulled up to VCCIO of the bank containing the JTAG pins via 10 kΩ resistors. Isolate analog/digital ground planes if mixing ADCs on the same board.
Compliance Information
Compliance data not explicitly listed in verified distributor sources. The APEX-20K family predates widespread RoHS transition; designers requiring RoHS compliance should request documentation from the distributor or select a RoHS-marked variant if available.
