An FPGA (Field-Programmable Gate Array) is a type of programmable logic device that contains an array of configurable logic blocks (CLBs), embedded memory, and programmable interconnect fabric, allowing hardware designers to implement custom digital circuits after manufacture. FPGAs sit in the hierarchy between CPLDs (smaller, simpler programmable logic) and ASICs (fully custom, non-programmable ICs), offering high logic density, parallel processing, and reprogrammability. APEX 20KC devices specifically combine Look-Up Table (LUT)-based logic with embedded dual-port RAM blocks called ESBs (Embedded System Blocks), forming a hybrid programmable platform on a single die.
Key specifications include a maximum internal clock frequency of 301.21 MHz, up to 700 user I/O pins, embedded dual-port RAM totaling approximately 540 kbits, support for high-speed interfaces such as LVDS, and 4 phase-locked loops (PLLs) for clock management. The device offers a propagation delay of 1.79 ns in the I8 speed grade and supports in-system programmability via IEEE 1149.1 JTAG, making it suitable for high-throughput parallel data-path designs. The FC-FBGA-1020 (Flip-Chip Fine-pitch Ball Grid Array) package provides a high-pin-count, surface-mount solution with low parasitic inductance for high-speed signaling.
Typical applications include high-speed telecommunications backplanes, parallel DSP pipelines, ASIC prototyping, multi-channel data acquisition front-ends, and legacy industrial control systems. The wide I/O count and PLLs make it a strong fit for bus-width conversion and clock-domain crossing designs.
When designing with the EP20K1000CF33I8N, ensure proper decoupling of the 1.8 V core rail with low-ESR ceramic capacitors placed close to the package balls, and follow Altera's recommended power-up sequencing for the APEX 20KC family. Configuration via JTAG or EPC configuration devices should respect the documented voltage thresholds to avoid partial configuration states.

主要差異化特點
- Highest-density APEX 20KC variant in the FC-FBGA-1020 footprint (對比EP20K600CF33I8N)
- Industrial temperature range (I8 speed grade) for harsh-environment deployment (對比EP20K1000CF33C8ES)
- Enhanced APEX 20KE variant as drop-in upgrade for higher performance (對比EP20K1000EFC33I8N)
設計說明
The EP20K1000CF33I8N requires a clean 1.8 V core supply within the 1.71 V to 1.89 V tolerance window. Estimated: at typical APEX 20KC core current of 1.5-2.5 A for the 1M-gate variant, the design must provide a low-noise LDO or DC-DC regulator with at least 3 A headroom. Bulk decoupling of 100 µF tantalum plus 10 µF ceramic, with 0.1 µF and 0.01 µF ceramics placed close to each power-ball cluster, is critical for APEX 20K family operation. Use separate analog and digital ground planes stitched together at a single point under the package.
The FC-FBGA-1020 package has 1020 balls on a fine pitch (typically 1.0 mm). PCB design requires microvia (HDI) stack-up or via-in-pad for reliable breakout. Reference the official Altera APEX 20K design guidelines for ball-pad geometry, solder-mask-defined vs non-solder-mask-defined pad selection, and escape-routing recommendations. All unused I/O balls should be left floating or tied to a defined logic level per APEX 20K configuration rules.
The EP20K1000CF33I8N is part of an obsolete family. Configuration via JTAG or EPC devices must respect the APEX 20K voltage thresholds (typically 3.3 V for MSEL pins); using modern configuration voltages will damage the device. Programming file format is .sof/.pof - designers migrating to newer families (Cyclone, Stratix) must recompile. Sourcing from non-franchised channels risks counterfeit or remarked parts; always request traceability documentation and date-code verification for legacy Altera devices.
合規資訊
RoHS, REACH, and lead-free status not explicitly stated in the verified distributor data. APEX 20KC predates widespread RoHS adoption; many parts in the field are tin-lead (SnPb) finishes. Verify with manufacturer documentation for specific date codes when RoHS compliance is required.
