EP3C80F780I7N 概要
A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines programmable logic blocks, interconnect, and I/O cells on a single semiconductor die. Within the broader taxonomy, an FPGA belongs to the integrated circuit family, sits under programmable logic devices, and is commonly used for parallel digital signal processing, hardware acceleration, glue logic, and rapid prototyping. The Cyclone III family specifically targets low-cost, low-power, high-volume applications where designers need substantial logic and memory but want to minimize static and dynamic power compared with prior Cyclone generations.
Key features include 81,264 logic elements, 2,810,880 RAM bits, 429 maximum user I/Os, four PLLs for clock management, and 20 global clock networks. The FBGA-780 package exposes 4 phase-locked loops for clock synthesis and distribution, supporting common telecom and video clock rates. The device operates from a 1.2 V core supply with separate I/O banks that can be configured to 1.5 V, 1.8 V, 2.5 V, 3.3 V, or differential signaling standards including LVDS.
From an architecture standpoint, Cyclone III uses 60 nm process geometry with embedded SRAM configuration cells and a MultiTrack interconnect structure. Logic elements combine a 4-input look-up table (LUT), a programmable register, and carry-chain arithmetic support. Embedded memory blocks (M9K blocks) deliver true dual-port, single-port, shift-register, and ROM modes, and DSP blocks enable hardware multiply-accumulate operations without consuming general logic.
Typical applications include industrial control and motor drives, video processing and broadcast equipment, telecom interface cards, test and measurement instrumentation, and consumer electronics requiring flexible I/O. The wide I/O count also makes the EP3C80 suitable for prototype ASIC replacement and parallel data acquisition systems.
When designing with this device, ensure PCB layout accounts for the 1 mm ball pitch and 29 x 29 mm footprint of the FBGA-780 package; use at least 6-layer stack-up with dedicated power and ground planes, and follow the Intel pin connection guidelines for unused pins and bank power. Quartus II (or the current Quartus Prime) design software is required for synthesis, place-and-route, and configuration bitstream generation.

設計ノート
The 780-FBGA package uses a 1 mm ball pitch and 29 x 29 mm footprint, requiring at least a 6-layer PCB stack-up with continuous ground and power planes. Per the Cyclone III pin connection guidelines, vias-in-pad are recommended for inner balls, and all four corner balls plus center balls should be connected to ground for thermal dissipation and signal return paths. Use 0.5 oz copper on outer layers and 1 oz on inner power/ground planes to meet FBGA-780 current and thermal demands.
Estimated: at maximum resource utilization, a Cyclone III EP3C80 draws around 1.5-2 A on the 1.2 V VCCINT rail. Decouple VCCINT with 4-6 0.1 uF ceramic capacitors placed within 100 mil of the package, plus 2 x 10 uF bulk capacitors near the supply pins. VCCIO banks must each be decoupled with 0.1 uF and 10 uF capacitors per bank, sized for the chosen I/O standard's switching current. Use a dedicated low-dropout regulator with soft-start for VCCINT to limit inrush at configuration.
Route all differential pairs (LVDS, RSDS) with 100 ohm differential impedance and matched lengths within 20 mil. Match length on global clock nets to within 50 mil to avoid skew across the 472 MHz internal frequency range. Place PLL power pins with their own filtered supplies or ferrite beads; isolate PLL analog ground from digital ground and join at a single point near the FPGA. JTAG and configuration pins need 4.7 kohm pull-ups to VCCIO per the Cyclone III handbook.
Do not leave configuration pins floating during operation - TMS, TCK, TDI, and nCONFIG each need explicit pull-up or pull-down treatment per the configuration scheme. Avoid driving LVDS inputs before VCCINT and VCCIO are fully ramped, or input failure can occur. Do not assume speed grades are interchangeable: an 'I7' device is industrial temp grade 7, while 'C8' is commercial temp grade 8 (faster timing); verify both temperature and speed grade match your design before substituting.
コンプライアンス情報
