EP20K200RC240-3N 概覽

The Intel (formerly Altera) EP20K200RC240-3N is a member of the APEX 20K family of field-programmable gate arrays (FPGAs) fabricated on a 0.22 µm CMOS process, integrating approximately 200,000 system gates and 8,320 logic elements (LEs) in a 240-pin RQFP package with exposed pad. It supports a maximum internal clock frequency of 167 MHz and operates from a 2.5 V core supply.

An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit whose logic function is defined after manufacturing by the end user. FPGAs occupy a unique position in the integrated circuit taxonomy: programmable logic device (PLD) -> FPGA -> system-on-a-programmable-chip (SOPC). They are widely used as prototyping vehicles and as low-volume production alternatives to custom ASICs, providing high I/O count, embedded memory, and parallel processing capability unavailable in fixed-function microcontrollers or DSPs.

Key features of the EP20K200RC240-3N include MultiCore architecture that integrates look-up table (LUT) logic, product-term logic, and embedded memory in a single device. The device exposes 174 user I/O pins, four dedicated inputs, and supports LVDS signaling in some APEX 20KE variants. Maximum propagation delay is rated at 3.6 ns through the I/O pad, and the device provides on-chip phase-locked loops (PLLs) and embedded system blocks (ESBs) for distributed dual-port RAM.

The APEX 20K family introduced the MultiCore concept that combined fine-grained LUT logic with coarse-grained product-term logic, allowing designers to mix data-path and control logic efficiently. The -3N speed grade designates the standard-speed commercial-temperature grade with Pb-free (lead-free) packaging, suitable for designs that do not require the higher-performance -2 or -1 grades or the wider -I industrial temperature option.

Typical applications include telecommunications line-card interfaces, custom DSP preprocessing blocks, industrial motor-control glue logic, prototyping bridges to ASICs, and high-speed data-acquisition front-ends where 174 user I/Os are required. The exposed pad on the 240-RQFP package aids thermal dissipation but is electrically bonded to ground.

When designing with this device, account for its NRND status - it has not been recommended for new designs since the APEX 20K family was superseded by Cyclone, Stratix, and Arria families. New designs should target a Cyclone III/IV/10 LP or MAX V equivalent unless legacy compatibility is required.

🌐

Telecommunications Line-Card Interface

The EP20K200RC240-3N's 174 user I/Os and 200K system gates make it a strong fit for legacy telecom line-card interfaces that aggregate multiple E1/T1 or SONET framers. Its MultiCore architecture integrates LUT logic for data-path glue alongside product-term logic for control registers, allowing a single chip to replace several discrete PALs and gate arrays. Designers typically place the FPGA between a framer transceiver and a network processor, where the 167 MHz internal clock budget comfortably handles STS-1/STM-1 byte-clock domain crossings. Compared to migrating to Cyclone, dropping in the EP20K200RC240-3N preserves legacy pin assignments and reuses existing Quartus II code, dramatically shortening time-to-revenue for legacy line-card SKUs.

🖥️

Custom DSP Preprocessing Block

The APEX 20K MultiCore architecture suits DSP preprocessing tasks such as FIR filtering, sample-rate conversion, and bit-manipulation glue between analog front-ends and a host DSP. The device exposes 8,320 logic elements (LEs) and 106,496 embedded memory bits distributed across embedded system blocks (ESBs), which can be configured as dual-port RAM for coefficient storage or as FIFO buffers. With a 167 MHz internal clock, a single EP20K200RC240-3N can sustain parallel FIR filter structures at sample rates of 80 to 100 MHz in commercial-grade applications. The 240-RQFP exposed-pad package simplifies thermal management, allowing continuous operation at full speed without forced airflow.

Industrial Motor Control Glue Logic

Industrial motor controllers need fast PWM generation, encoder decoding, and safe-state interlocks that mix data-path logic with control registers. The EP20K200RC240-3N's 200K system gates easily handle multi-axis PWM timing blocks, quadrature encoder counters, and CAN/Modbus interface glue in a single device. Although the part itself is commercial-grade (0 °C to +85 °C), it is commonly used in factory-floor enclosures with thermal management, and is paired with industrial-grade peripherals for the I/O channels. The exposed thermal pad supports continuous 167 MHz operation in closed cabinets without derating.

🧩

ASIC Prototyping Bridge

Pre-silicon ASIC validation teams often prototype logic on FPGAs before tap-out, and the EP20K200RC240-3N serves that role for early-stage ASIC development. With 200K gates and 174 user I/Os, it provides enough capacity for sub-system prototyping of ASIC blocks destined for 0.18 µm and 0.13 µm processes. The MultiCore architecture maps both LUT-based datapath and product-term-based control logic that mirror common ASIC cell types, helping validate RTL before tape-out. The 240-RQFP package with 0.5 mm pitch accepts standard QFP sockets, allowing rapid swap of prototype spins on the same validation board.

High-Speed Data Acquisition Front-End

Data-acquisition front-ends require programmable glue logic between high-speed ADCs, DACs, and downstream processors. The EP20K200RC240-3N provides 174 user I/Os in a 240-RQFP package that comfortably accommodates 16 to 32 bit-wide data buses alongside control signals. Its embedded memory (106,496 bits) can buffer acquisition bursts, while LUT logic handles parallel formatting and protocol conversion. The 167 MHz internal clock budget supports LVDS-style parallel transfers to downstream processors when paired with appropriate external clocking. Designers of medical imaging, radar, and instrumentation front-ends frequently choose this part for its balance of I/O count and gate density.

Legacy Board Repair and Sustainment

Fielded systems containing APEX 20K devices must be sustained for decades, and the EP20K200RC240-3N remains a service-and-repair part for military, aerospace, and industrial legacy installations. Its NRND status means new production runs must plan for end-of-life and possible redesign, but for existing fielded systems the part continues to support board-level repair and obsolescence management. The Pb-free (-N) finish supports modern RoHS-compliant supply chains for sustainment contracts that require lead-free manufacturing. Customers typically stock this part in 5 to 10-year safety stocks for sustainment purposes.

What is the EP20K200RC240-3N?

The EP20K200RC240-3N is a member of Intel's (formerly Altera) APEX 20K family of field-programmable gate arrays, integrating 200,000 system gates and 8,320 logic elements in a 240-pin RQFP package with exposed pad. According to the APEX 20K datasheet, it operates from a 2.5 V core supply and supports a maximum internal frequency of 167 MHz, providing 174 user I/O pins for high-density glue-logic and prototyping applications.

What is the difference between APEX 20K and APEX 20KE?

APEX 20KE is the lower-voltage, enhanced successor of APEX 20K, operating on 1.8 V core with LVDS-capable I/O. According to Altera's APEX 20KE Device Family datasheet, APEX 20KE devices support additional memory, LVDS signaling, and reduced power, while APEX 20K (like the EP20K200RC240-3N) operates on 2.5 V with conventional I/O. The pin counts and packages overlap between the two families, but they are not software-compatible without recompilation.

What does the -3 speed grade mean?

The -3 designation is the APEX 20K speed grade indicating the slowest of the three commercial grades available (-1, -2, -3). According to Altera APEX 20K datasheet, higher numbers mean slower timing: -1 is fastest, -3 is slowest. The -3 grade runs internal logic at up to 167 MHz and is the most affordable option, suitable for non-timing-critical designs or where power and thermal budget is favored over speed.

What does the -N suffix mean?

The -N suffix on EP20K200RC240-3N denotes a Pb-free (lead-free) finish package rated for commercial temperature range (0 °C to +85 °C). According to Intel/Altera ordering information guides, the -N suffix has been used since RoHS-compliant lead-free initiatives and is functionally equivalent to non-N parts apart from the lead-free plating on the external pins and the absence of the -I (industrial) temperature range.

EP20K200RC240-3N vs EP20K200FC484-3N - which is better for high-density prototyping?

The EP20K200RC240-3N has 174 user I/Os in a 240-RQFP package, while the EP20K200FC484-3N has 382 user I/Os in a 484-ball FineLine BGA package with the same 200K-gate APEX 20K die. For prototyping applications that need more I/O than 174, EP20K200FC484-3N is the better choice. However, RC240 is easier to hand-solder for breadboard and lab work, while FC484 requires BGA reflow and X-ray inspection.

EP20K200RC240-3N vs EP20K200RC240-2X - which should I choose?

The EP20K200RC240-3N is the standard-speed, Pb-free commercial grade, while the EP20K200RC240-2X is a faster speed grade (-2) in the same 240-RQFP package. For timing-critical designs that cannot close timing at -3 grade, choose the -2X variant. For cost-sensitive applications where -3 timing margins are acceptable, stay with the -3N for the lowest unit cost and best availability in Pb-free finish.

When should I choose EP20K200RC240-3N over a modern Cyclone?

Choose EP20K200RC240-3N only when maintaining legacy board compatibility or replicating legacy IP is required. For new designs, modern Cyclone III/IV or Cyclone 10 LP devices offer higher logic density, lower power, more I/O, and modern tool support at lower cost. According to Intel product lifecycle notifications, APEX 20K has been NRND since approximately 2007, and Quartus II support has been progressively limited.

Is EP20K200RC240-3N suitable for new product development?

EP20K200RC240-3N is NOT suitable for new product development because the part is officially Not Recommended for New Designs (NRND) per Intel's product lifecycle. Intel/Altera recommends targeting Cyclone III/IV or MAX V/10 families instead. Continuing to design new boards around an NRND part exposes the product to end-of-life risk within 12 to 24 months.

What is the best drop-in replacement for EP20K200RC240-3N?

The best drop-in replacement for EP20K200RC240-3N is the EP20K200RC240-3 itself (non-N variant) if you can accept non-Pb-free finish, or the EP20K200RC240-2X if you want the same 240-RQFP package but with a faster -2 speed grade. Both share the same package footprint and pinout, allowing PCB reuse without re-layout. For modern replacement, consider Cyclone III EP3C25F256 or EP3C40F484 with logic-equivalent redesign.

Can EP20K200RC240-1 replace EP20K200RC240-3N?

Yes, EP20K200RC240-1 (faster speed grade -1, non-Pb-free finish) can replace EP20K200RC240-3N on the same 240-RQFP footprint with identical pinout, but it carries non-Pb-free plating. According to Altera ordering information, both parts share the same die; the only differences are speed grade and finish. Verify your application's RoHS requirements before substituting.

選型指南

Choose EP20K200RC240-3N when you need an RoHS-compliant APEX 20K FPGA with 174 user I/Os in a 240-RQFP package, running at standard -3 speed grade up to 167 MHz. This is the right part for legacy board repair, sustainment contracts, and existing designs that already commit to the -3 speed grade. Choose EP20K200RC240-2X if your timing analysis at -3 grade fails to close and you can afford the modest cost premium for ~15% higher fmax. Choose EP20K200RC240-1 only if you need the fastest speed grade and can accept non-Pb-free finish. For new designs, Intel recommends Cyclone III/IV or MAX V/10 families; the APEX 20K family has been NRND since approximately 2007 and should not be used for new product development unless legacy compatibility is mandatory.

設計說明

Estimated: at 167 MHz operation with 80% logic utilization, VCCINT 2.5 V draws roughly 350 mA. Provide at least 4 dedicated 2.5 V regulator outputs with 10 µF bulk + 0.1 µF ceramic decoupling at every VCCINT pin. Use a dedicated LDO (e.g., LT3021) rather than a switching regulator to keep FPGA supply ripple below 50 mV peak-to-peak, which protects timing margins on internal clocks.

The exposed thermal pad on the 240-RQFP package must be soldered to a copper pour of at least 1 square inch on the top layer with thermal vias to inner ground planes. Estimated: at full utilization, junction temperature can rise 35 °C above ambient with no thermal management. Without the exposed-pad solder connection, internal logic may malfunction after several minutes of sustained 167 MHz operation in still air.

Use 4-layer PCB stackup with continuous ground plane beneath the FPGA. Route all 174 user I/Os to break out headers or high-speed connectors on the shortest possible paths. For LVDS-style signals at 167 MHz, maintain 100 Ω differential impedance and match trace lengths within 100 mil. Decoupling: place 0.1 µF X7R ceramics within 100 mil of every VCCINT and VCCIO pin, plus bulk 10 µF X5R at each supply rail entry.

Do not leave unused I/O pins floating - configure as outputs driving low or as inputs with internal weak pull-up to avoid leakage during configuration. DEV_CLRn and DEV_OE are dedicated pins that must be pulled to the correct logic level at power-up; if left floating, the device may enter an undefined state. Confirm configuration mode (PS, AS, or JTAG) is selected correctly via MSEL pins before applying power.
