EP20K30EQC208-3 Tóm tắt

The Altera EP20K30EQC208-3 is a member of the APEX-20KE family of programmable logic devices, integrating 30,000 gates, 1,200 logic elements, and 24,576 RAM bits in a 208-pin PQFP (28x28 mm) package. It operates from a 1.71V to 1.89V core supply and is fabricated on a 0.22 µm CMOS process with LVDS-compatible I/O support.

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.

The EP20K30EQC208-3 uses a 208-BFQFP (also called 208-PQFP or FQFP) package measuring 28x28 mm with gull-wing leads at a 0.50 mm pitch. This square fine-pitch quad flat pack is surface-mountable and is among the largest non-BGA packages in the APEX 20KE family, providing 125 usable user I/O pins.

What is the difference between EP20K30EQC208-3 and EP20K30EQC208-2?

The EP20K30EQC208-3 is the fastest -3 speed grade while the EP20K30EQC208-2 is the slower -2 speed grade of the same die and 208-pin PQFP package. The -3 grade offers higher fMAX (~435 MHz vs lower) at the same price tier; otherwise the pinout, RAM, logic, and I/O count are identical, making them drop-in compatible.

What is a drop-in replacement for EP20K30EQC208-3?

The closest drop-in replacement is EP20K30EQC208-1 or EP20K30EQC208-2, which share the same 208-BFQFP package, die, and pinout but a different speed grade. For legacy sourcing, Rochester Electronics maintains inventory of the original Altera-spec part. No cross-brand drop-in exists because APEX 20KE is a proprietary Altera MultiCore architecture.

Is the EP20K30EQC208-3 still in production?

The EP20K30EQC208-3 is listed as obsolete/legacy. Altera/Intel discontinued the APEX 20KE family and now directs customers to Cyclone or Arria series. Authorized stocking distributors such as Rochester Electronics, Microchip USA, and Vyrian still hold inventory for maintenance and legacy designs, with prices reflecting scarcity.

What is the lead time for EP20K30EQC208-3?

Lead time for the obsolete EP20K30EQC208-3 typically ranges from 4 to 12 weeks through authorized distributors like Rochester Electronics, Microchip USA, and SZComponents, depending on remaining stock. For volume orders above 1,000 units, expect longer lead times and price negotiation; planning ahead is essential.

How much does EP20K30EQC208-3 cost as of 2026-09-08?

Pricing for EP20K30EQC208-3 as of 2026-09-08 ranges from approximately $95 per unit at qty 1 to roughly $62 at qty 1,000, depending on distributor and stock. Distributors such as SZComponents, Vyrian, Microchip USA, and Rochester Electronics offer competitive quotes; the part's obsolete status drives the higher unit price versus newer Cyclone devices.

Where to buy EP20K30EQC208-3 online?

Authorized online sources for EP20K30EQC208-3 include DigiKey Marketplace (Rochester Electronics listing), Octopart aggregator (Intel/Altera), SZComponents, Microchip USA, Vyrian, and Altera-Micro.com.

Engineers should know the following key specifications: 30,000 gates, 1,200 logic elements, 24,576 RAM bits, 125 user I/O, 435 MHz maximum internal frequency, 1.71-1.89V core supply, 2.5V/3.3V LVTTL/LVCMOS I/O with 5V tolerance, JTAG (IEEE 1149.1) programming, and a 208-BFQFP PQFP package at 28x28 mm.

What is the best Altera equivalent for EP20K30EQC208-3?

The best Altera equivalent for EP20K30EQC208-3 within the APEX 20KE family is the EP20K30EQC208-2, sharing identical 208-BFQFP packaging and pinout but a slower -2 speed grade. For functional equivalence in modern silicon, the Intel Cyclone IV EP4CE30F29C7N provides similar logic density with significantly lower power and active product lifecycle.

Can the EP20K30EQC208-3 be used in new designs in 2026?

The EP20K30EQC208-3 should not be used in new designs in 2026 because it is obsolete and lacks long-term availability guarantees. For new designs requiring similar logic density (~30K gates), Intel recommends Cyclone IV or Cyclone 10 LP families with active lifecycles, lower power, and modern tool support via Quartus Prime.

How do I program the EP20K30EQC208-3?

The EP20K30EQC208-3 is programmed via the JTAG (IEEE 1149.1) interface using Altera's legacy programming tools such as Quartus II programmer or ByteBlaster cables. Configuration bitstreams are loaded serially through TDI/TDO pins; consult the APEX 20KE datasheet for TCK frequency limits and BSDL file downloads.

Hướng dẫn chọn lựa

Choose the EP20K30EQC208-3 when you need a 30K-gate APEX 20KE device with the highest speed grade (-3) for timing-critical designs in legacy 208-BFQFP footprints. For designs with relaxed timing budgets, the EP20K30EQC208-1 or EP20K30EQC208-2 are drop-in alternatives at lower cost. The EP20K30EQC208-3N is preferred when lead-free/RoHS compliance is mandatory. For designs exceeding 30K gates, the EP20K60EQC208-3 (60K) and EP20K100EQC208-3 (100K) provide drop-in superset upgrades in the same package. All five parts share identical 208-BFQFP pinout, enabling single PCB layout across the entire density range.

Ghi chú thiết kế

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.
