EP2C20F484I8 - Cyclone II FPGA 18,752 LEs 484-FBGA | Intel / Altera
MPN: EP2C20F484I8 ✗ Cuối đờiEP2C20F484I8 Tóm tắt
A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs), programmable interconnects, and embedded memory and DSP resources that can be re-programmed by the designer after manufacture. FPGAs occupy the top tier of the digital programmable logic hierarchy: FPGA -> programmable logic -> ASIC alternative -> digital IC. They are valued for parallel processing, deterministic latency, hardware flexibility, and rapid time-to-market versus application-specific fixed-function ASICs.
Key features of the EP2C20F484I8 include 18,752 logic elements distributed across 1,196 logic array blocks (LABs), embedded multiplier blocks for low-cost DSP, 4 phase-locked loops (PLLs) for clock management, support for external memory interfaces including DDR/DDR2 SDRAM and QDRII SRAM, and a flexible LVDS/LVCMOS/LVTTL I/O standard mix. The device is offered in the -I8 speed grade with industrial temperature range (-40C to +100C junction).
The Cyclone II architecture combines a four-input lookup table (LUT)-based logic fabric with M4K embedded memory blocks and embedded 18 x 18 multipliers. Designers use the Altera/Intel Quartus II design suite for synthesis, place-and-route, timing closure, and bitstream generation. The -I8 industrial-grade speed bin balances timing margin against power consumption for cost-sensitive designs.
Typical applications include industrial motor control, video surveillance and image processing, automotive infotainment prototypes, communications line cards, low-cost ASIC prototyping, and consumer electronics such as digital displays and set-top boxes. The 315 I/O count supports wide parallel buses and high-speed LVDS interfaces commonly needed in video and industrial control.
When designing with this part, allocate sufficient decoupling (100 nF + bulk) near each power pin, follow the Cyclone II board design guidelines for BGA breakout and impedance-controlled routing, and validate the design in the Quartus II toolchain with industrial-grade timing models. Note that Cyclone II is a mature legacy family - confirm long-term availability before committing to new designs.

Ứng dụng tiêu biểu
EP2C20F484I8 phù hợp cho 6 Áp dụngs: Industrial Motor Control, Video Surveillance & Image Processing, Automotive Infotainment Prototyping, Communications Line Card Glue Logic, Low-Cost ASIC Prototyping, Consumer Display & Set-Top Box Designs.
Industrial Motor Control
The EP2C20F484I8 fits industrial motor control because its 315 user I/Os comfortably handle quadrature encoder inputs, PWM channels, gate-driver signals, and isolated communication interfaces on a single device. With 18,752 logic elements and embedded multipliers, it can implement field-oriented control (FOC) state machines and space-vector modulators without external DSP. Industrial temp grade (-40C to +100C) supports cabinet-mounted drives. Power dissipation at 1.2 V core is moderate enough for fan-less enclosures, and Quartus II IP cores simplify integration with Hall sensors and resolver front-ends.

Video Surveillance & Image Processing
The EP2C20F484I8 suits video surveillance designs because its 18,752 LEs, embedded 18 x 18 multipliers, and LVDS I/O capability support real-time image-processing pipelines at D1/720p resolutions. The 484-FBGA package exposes 315 I/Os to interface parallel image sensors and DDR2 SDRAM frame buffers. At 402 MHz internal clock, the device sustains typical video-processing throughput for motion detection and H.264 pre-processing. Engineers can leverage Altera's video and DSP IP suite in Quartus II to shorten development cycles for IP-camera and DVR platforms.
Được đề xuất
Automotive Infotainment Prototyping
The EP2C20F484I8 works well as a prototyping platform for automotive infotainment, where parallel LVDS links to displays, CAN/LIN bus controllers, and audio CODEC interfaces benefit from the 315 available I/Os. The 18,752 logic-element fabric holds display controllers, audio DSP chains, and connectivity stacks. Industrial temp grade suffices for cabin environments; for under-hood AEC-Q100 needs, validate against newer Cyclone IV or Cyclone 10 LP parts. Quartus II supports automotive IP for faster proof-of-concept cycles.
Được đề xuất
Communications Line Card Glue Logic
The EP2C20F484I8 serves as flexible glue logic on communications line cards, bridging framer/mapper ASICs, packet processors, and backplane transceivers through its 315 I/Os and four PLLs. Its 18,752 LEs handle protocol encapsulation, SERDES aggregation, and timing-distribution functions at line-card densities. Industrial temp grade supports central-office and outdoor-cabinet deployments. The 4 PLLs enable multiple clock domains for hybrid TDM/Ethernet fabrics.
Được đề xuất
Low-Cost ASIC Prototyping
The EP2C20F484I8 is widely used for ASIC prototyping because its 18,752 logic elements, embedded multipliers, and 239,616 RAM bits provide ample capacity for partitioning mid-complexity ASIC RTL. The 484-FBGA package offers fast I/O access for logic-analyzer and pattern-generator probing. Quartus II supports incremental compilation, enabling multi-engineer RTL bring-up. Designers can re-target verified RTL to lower-cost Cyclone IV E or Cyclone 10 LP parts for production, keeping the prototype platform pin-compatible.
Được đề xuất
Consumer Display & Set-Top Box Designs
The EP2C20F484I8 powers consumer display controllers and set-top box (STB) mainboards because its 315 I/Os drive HDMI/LVDS bridges, flash storage, and tuner interfaces on a single chip. At 1.2 V core, the device delivers adequate performance for video decode assist and on-screen-display overlays while keeping BOM and power low. Quartus II reference designs accelerate HDMI receiver and scaler implementations. For high-volume STB designs, validate long-term supply given Cyclone II NRND status.

Ghi chú thiết kế
The EP2C20F484I8 requires a clean 1.2 V core supply; per the Cyclone II Device Handbook, place 0.1 uF decoupling capacitors as close as possible to every VCCINT pin and bulk 22-100 uF tantalum or ceramic caps at board entry. Add dedicated 2.5 V VCCIO supplies if any I/O bank uses LVCMOS25 or LVDS. PLL analog supplies (VCCA_PLL) must be filtered through ferrite beads and decoupled with 0.1 uF + 10 uF capacitors to achieve low PLL jitter.
The 484-FBGA package requires 0.8 mm or 1.0 mm ball pitch (verify exact mechanical spec from the package outline drawing). Use a 4-6 layer PCB with dedicated ground and power planes; route all differential pairs (LVDS) with 100 ohm differential impedance and matched lengths (within 20 mil). Provide microvia-in-pad or dog-bone fan-out for BGA escape routing. Refer to the Cyclone II board design guidelines for trace-width and via-stub recommendations.
At typical utilization (60-70% logic, 50% toggle rate) and 1.2 V core, the EP2C20F484I8 dissipates roughly 1-2 W - the FBGA-484 thermal resistance is sufficient for natural-convection cooling in most enclosures. For enclosed industrial cabinets above +60C ambient, add a thermal pad under the package connected to an internal ground plane to spread heat. Use the Quartus II PowerPlay analyzer to estimate worst-case power before finalizing the mechanical design.
Do not assume Cyclone II and Cyclone IV E bitstreams are interchangeable - even with pin-compatible packages, configuration files and JTAG IDs differ. When migrating between families, re-run synthesis and place-and-route in the target device library. Also, confirm MSL (Moisture Sensitivity Level) handling for the FBGA package - typical MSL3 requires pre-bake before reflow if the factory floor exposure exceeds the rated floor life.
