MPN: EP3C80F484C6 ⚠ Lần mua cuốiEP3C80F484C6 Tóm tắt
A Field Programmable Gate Array (FPGA) is a programmable logic device that allows engineers to implement custom digital circuits through configurable logic blocks (CLBs), programmable interconnects, and dedicated hardware resources such as embedded multipliers, memory blocks, and high-speed transceivers. FPGAs sit in the broader taxonomy of programmable logic devices -> logic ICs -> integrated circuits, offering hardware-level parallelism and reconfigurability that microcontrollers and ASICs cannot match for high-throughput or evolving-design applications.
Key features of the EP3C80F484C6 include up to 472.5 MHz maximum operating frequency, 488 (18x18) embedded multipliers for DSP workloads, four phase-locked loops (PLLs) for clock management, and support for external memory interfaces including DDR, DDR2, SDRAM, and QDRII SRAM. The device supports popular I/O standards such as LVDS, SSTL, HSTL, and PCI/PCI-X through its 484-ball FBGA interface, enabling flexible system integration.
The Cyclone III architecture leverages a 65 nm low-power process and an efficient logic fabric to deliver high logic density at low static power. Embedded memory blocks (M9K) total 2,810,880 bits, distributed across the die for high-bandwidth local storage. The combination of logic density, DSP blocks, and memory makes the EP3C80F484C6 well suited for digital signal processing, video bridging, industrial control, and communications infrastructure.
Typical applications include industrial motor control, video surveillance and image processing, software-defined radio front-ends, and embedded vision systems. The Cyclone III family was a popular low-power choice for cost-sensitive, high-volume designs during the late 2000s, and parts remain available through authorized distributors supporting long-lifecycle programs.
When designing with this device, ensure proper decoupling on each power rail (VCCINT, VCCA, VCCIO) and follow Altera's recommended FPGA PCB layout guidelines for BGA packages. Engineers should also verify the latest Quartus II support status, as Intel/Altera has since introduced Cyclone IV and Cyclone V successors; however, EP3C80F484C6 remains widely deployed in existing designs.
This page synthesizes distributor pricing, drop-in Cyclone III family alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers select, source, and design with this legacy FPGA confidently.

Ghi chú thiết kế
The EP3C80F484C6 requires three separate power rails: VCCINT (1.2 V core), VCCA (2.5 V PLL analog), and VCCIO (1.2 V-3.3 V I/O banks). Use a power-on reset sequencer or POR circuit to ensure VCCA rises no faster than VCCINT to prevent latch-up. Decouple each rail with bulk, mid-frequency, and high-frequency capacitors placed as close to the BGA balls as the PCB escape routing allows. Total quiescent current scales with logic utilization and clock frequency; estimate using the Cyclone III PowerPlay Early Power Estimator.
The 484-ball FBGA with 1.0 mm pitch requires at least 4 PCB layers with a dedicated ground plane under the device for return-path integrity. Use microvia (laser-drilled) stack-up to fan out the inner-row balls; dog-bone fan-out is acceptable but limits routing density. Match trace lengths within LVDS pairs to within 10 mils to maintain signal integrity at high toggle rates. Reference the Cyclone III Board Design Guidelines from the device handbook for via-in-pad, decoupling, and EMI recommendations.
Do not confuse 'C' (commercial temp grade) with 'I' (industrial) in the suffix - C6 is commercial, I7 is industrial. Verify MSEL[2:0] pins match the desired configuration scheme (AS, AP, FPP, PS) before PCB layout because these pins are not reconfigurable after board build. Always instantiate the Altera ALTPLL and ALTLVDS megafunctions from the Quartus II IP catalog rather than coding custom PLLs, as this guarantees silicon-validated timing closure. Confirm the latest Quartus II version supports your chosen Cyclone III device; legacy versions lack bug fixes for newer errata.
