EP20K30EQC208-3 概要
An FPGA (Field Programmable Gate Array) is a type of integrated circuit whose logic function is defined by the user after manufacture. FPGAs sit in the programmable logic hierarchy below ASICs and above fixed-function logic ICs, offering a balance of high integration density, parallel processing capability, and reconfigurability. APEX-20KE parts specifically belong to Altera's MultiCore architecture, which embeds look-up-table logic, product-term logic, and embedded memory blocks on a single die, enabling system-on-a-programmable-chip (SOPC) integration.
Key features of the EP20K30EQC208-3 include 125 user I/O pins, 1,200 logic elements, 24,576 total RAM bits, and a maximum internal operating frequency of 435 MHz. The device supports in-system programming via the IEEE 1149.1 JTAG interface and is built around the 2.5V/3.3V low-voltage bus standard with 5V-tolerant I/O. The 208-BFQFP package provides a low-cost surface-mount option for moderate-density designs.
The APEX-20KE MultiCore architecture combines lookup-table-based logic for register-intensive functions, product-term logic for arithmetic and fast adders, and embedded system blocks (ESBs) for memory and FIFO. This heterogeneous fabric optimizes logic utilization and routing delays versus monolithic LUT-only architectures, allowing designers to map DSP, datapath, and control logic efficiently on a single device.
Typical applications include telecommunications infrastructure, industrial control systems, glue logic replacement, custom peripheral interfacing, and legacy ASIC replacement prototyping. The combination of moderate gate count and PQFP packaging makes the EP20K30EQC208-3 well-suited for cost-sensitive designs where BGA packages are undesirable.
When designing with this part, ensure proper power decoupling near every VCC pin, follow Altera's JTAG programming guidelines for configuration, and respect the maximum I/O toggle rate and junction temperature limits stated for the -3 speed grade.
This page combines distributor pricing, drop-in alternatives, and practical design context that is not collected in a single place in the manufacturer datasheet, providing a synthesis useful for both new designs and legacy maintenance.

主な用途
EP20K30EQC208-3 の用途: 6 件s: Telecommunications Infrastructure, Industrial Control Systems, ASIC Prototyping and Replacement, Custom Peripheral Interfacing, Glue Logic Consolidation, Legacy Test and Measurement Equipment.
Telecommunications Infrastructure
The EP20K30EQC208-3's 30K gates and 125 I/O make it a strong fit for telecom line-card glue logic. Its 1.71-1.89V core with 5V-tolerant I/O interfaces cleanly to legacy 5V TTL buses while consuming modern low-voltage power. The MultiCore architecture efficiently implements ATM cell processing, HDLC framing, and Utopia bus interfacing at the 435 MHz internal fabric clock typical of -3 grade parts. Embedded system blocks (ESBs) provide 24 Kbits of RAM for small lookup tables and protocol state machines. The 208-BFQFP package is preferred over BGA for field-replaceable legacy line cards.
おすすめ
Industrial Control Systems
In industrial PLC and motion control backplanes, the EP20K30EQC208-3 provides 1,200 logic elements for combinational and sequential control logic, plus 24 Kbits of RAM for parameter storage and PID coefficient tables. The 125 user I/O directly drives 24V optically-isolated inputs and outputs through external buffers, with the 5V-tolerant I/O simplifying interface to legacy industrial buses. The 208-PQFP package withstands the through-hole rework common in industrial maintenance. With operating range -40C to +85C, it tolerates factory-floor thermal conditions when properly heatsinked.
おすすめ
ASIC Prototyping and Replacement
Designers use the EP20K30EQC208-3 as a low-cost ASIC emulator for ~30K-gate custom chips, leveraging the MultiCore fabric to model datapath, control, and embedded memory concurrently. The 24,576 RAM bits emulate small register files and FIFO buffers needed in custom ASIC verification. The 208-PQFP package allows direct footprint migration from packaged ASICs, accelerating prototype bring-up. Once the design is validated, the bitstream can be regenerated for smaller production FPGAs while keeping the EP20K30EQC208-3 as the engineering reference platform.
おすすめ
Custom Peripheral Interfacing
The EP20K30EQC208-3's 125 user I/O pins excel at bridging mismatched peripherals such as ISA/PCI buses to modern memory-mapped processors. Designers can implement custom DMA engines, scatter-gather controllers, and protocol converters within the 30K-gate fabric. The 5V-tolerant I/O directly connects to legacy peripheral signals without external level shifters, reducing BOM cost. The 435 MHz internal fabric clock supports high-throughput streaming interfaces while the 208-BFQFP package simplifies hand-soldering for prototype bring-up.
おすすめ
Glue Logic Consolidation
Replacing dozens of 74-series TTL/CMOS packages with a single EP20K30EQC208-3 reduces PCB area, power, and BOM count in legacy system designs. The 1,200 logic elements and 24 Kbits of RAM absorb address decoding, interrupt steering, bus arbitration, and FIFO buffering functions. Its 5V-tolerant I/O maintains compatibility with surrounding 5V logic families, while the 1.8V core lowers power versus original TTL implementations. The 208-PQFP package is a natural replacement footprint for multi-chip 74-series logic boards.
おすすめ
Legacy Test and Measurement Equipment
The EP20K30EQC208-3 supports custom pattern generation, signal conditioning, and timing-sequencer functions in legacy ATE platforms. Its 125 I/O pins handle parallel DUT interfaces, while the 1,200 logic elements implement programmable waveform tables with the embedded ESBs providing 24 Kbits of pattern memory. The 208-PQFP package allows repair-friendly socketed designs important in service shops maintaining long-life test equipment. Operating temperature -40C to +85C covers most laboratory and production-floor environments.

設計ノート
The EP20K30EQC208-3 requires both a 1.8V VCCINT core supply and a separate 2.5V or 3.3V VCCIO supply. Decouple every VCCINT and VCCIO pin with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, plus a 10 µF bulk tantalum or polymer capacitor near the package. Estimated core current at 435 MHz with full I/O toggling is approximately 200-400 mA; verify with the APEX 20KE power calculator spreadsheet. VCCIO current scales with I/O toggle rate and loading.
Estimated: at 1.8V core, ~300 mA ICC, and 100% I/O utilization, total power dissipation reaches roughly 0.6-1.0 W. The 208-BFQFP package has theta_JA around 35-40 C/W on a 4-layer JEDEC test board, giving a junction rise of ~35-40 C above ambient. For closed enclosures, attach a small clip-on heatsink or use top-side airflow to maintain Tj below 125 C in industrial (-40C to +85C ambient) deployments.
Do not apply 5V to any I/O pin even though the datasheet lists 5V tolerance - tolerance means the input will not be damaged, but VIH for proper logic-high detection still uses the VCCIO reference. Always tie unused I/O pins to a defined state per the APEX 20KE configuration guidelines. Ensure JTAG chain integrity by buffering TCK near the device if multiple parts share the chain, and respect the maximum TCK frequency stated in the datasheet.
Place the EP20K30EQC208-3 on the top side with all decoupling on the opposite layer directly beneath the VCC pins. Use a continuous ground plane under the device; avoid signal traces crossing beneath the PQFP body. Keep JTAG signals (TDI, TDO, TCK, TMS) short and routed together with a guard ground to prevent configuration noise. Provide 4-layer stack-up with dedicated VCCINT and VCCIO planes for designs exceeding 50 MHz internal clock rates.
