EP3C120F780I7 Descripción general
A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected by a programmable interconnect matrix, surrounded by programmable I/O cells. FPGAs sit at the top of the programmable logic hierarchy (CPLD -> FPGA -> SoC FPGA) and are used to implement arbitrary digital circuits, from glue logic and bus bridges to high-throughput parallel DSP pipelines and soft-core microprocessors. Unlike a fixed ASIC, the function is defined by a user-supplied bitstream stored in external configuration memory.
Key features of the EP3C120F780I7 include up to 531 user I/O pins, 4 PLLs for clock management, dedicated 18x18 hardware multipliers for DSP, and support for external memory interfaces including DDR/DDR2/QDRII SRAM. The device family provides up to 288 embedded 9x9 multipliers and 4 Mbits of on-chip RAM, making it suitable for cost-sensitive mid-density designs. Configuration is supported via passive serial, fast passive parallel, active serial (EPCS), and JTAG modes.
Architecturally, the Cyclone III EP3C120 uses a logic-array-based fabric with row and column interconnect, 8-input adaptive logic modules (ALMs), and per-MLAB distributed memory. Process technology is TSMC 65 nm low-power CMOS with 1.2 V core supply, giving a favorable performance-per-watt ratio compared to earlier Cyclone II and Stratix generations. The 780-FBGA package uses a wire-bond die with a controlled-impedance substrate, supporting LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards across 8 I/O banks.
Typical applications include industrial motor control and machine vision, video processing and display controllers, telecom line cards and baseband prototyping, low-cost software-defined radio, and PCI/PCI Express endpoint bridges. The wide operating temperature range also makes it attractive for military and aerospace subsystems where extended-temperature commercial-grade FPGAs are acceptable.
When designing with the EP3C120F780I7, plan configuration memory carefully: the uncompressed bitstream exceeds 25 Mbits, so a 64-Mbit EPCS or parallel flash is typically required. Use the Quartus II PowerPlay analyzer early to model thermal dissipation, and follow the Altera pin connection guidelines for unused I/O banks to avoid leakage. Decoupling should follow the Altera reference design with 100 nF plus 10 µF bulk capacitors per power pin pair.

Aplicaciones típicas
EP3C120F780I7 es adecuado para 6 aplicacións: Industrial Motor Control & Drive, Video Processing & Display Controllers, Telecom Line Card & Protocol Bridging, Software-Defined Radio Baseband, PCI/PCI Express Endpoint Bridge, Machine Vision & Image Acquisition.
Industrial Motor Control & Drive
The EP3C120F780I7 fits industrial motor control because its 119,088 logic elements and 288 18x18 multipliers can implement multi-axis field-oriented control (FOC) loops, encoder feedback decoding, and PWM generation simultaneously. The 4 on-chip PLLs generate the switching-frequency clock and the resolver-excitation reference from a single 50 MHz crystal, eliminating external clock buffers. With 531 user I/Os the device interfaces directly to multi-channel ADCs for current sensing, to gate drivers via differential LVDS, and to industrial Ethernet MACs. The -40C to +100C industrial temperature grade allows deployment in uncooled cabinet locations.
Recomendado
Video Processing & Display Controllers
The EP3C120F780I7 is well matched to mid-density video processing: 3,981,312 bits of embedded memory provide enough line buffers for 1080p60 color-space conversion and deinterlacing, while 288 18x18 multipliers accelerate scaling and sharpening filters in real time. The 531 I/Os support parallel RGB/CMOS camera input, HDMI/DVI TMDS links via LVDS, and BT.656/1120 display output. The 65 nm process keeps dynamic power manageable at 148.5 MHz pixel clocks, and the 4 PLLs generate independent video, audio, and memory clocks. Altera's VIP suite can drop pre-verified video IPs directly into the fabric.
Recomendado
Telecom Line Card & Protocol Bridging
Telecom line cards need dense glue logic, multi-protocol bridging, and timing recovery, all of which the EP3C120F780I7 provides. The 119K logic elements can host 8-16 channelized T1/E1 framers plus an HDLC controller and a Utopia/Serial RapidIO bridge on a single device, replacing multiple CPLDs and ASICs. The 4 PLLs derive per-channel clocks from a Stratum-3 reference, and the 531 I/Os mate with HFR/Framer ICs through HSTL/SSTL interfaces. The industrial -40C to +100C temperature grade covers outdoor DSLAM and base-station mezzanine cards.
Recomendado
Software-Defined Radio Baseband
Low-cost software-defined radio baseband designs map naturally onto the EP3C120F780I7: the 288 18x18 hardware multipliers implement digital down/up-conversion, channelization, and pulse-shaping filters, while the embedded memory holds coefficient banks for adaptive demodulation. The 4 PLLs derive sampling and IF clocks from a single TCXO. The 531 I/Os connect to dual ADCs/DACs over LVDS, to a host CPU via parallel or serial interface, and to front-panel status LEDs. The 65 nm low-power process gives favorable W/MHz for portable SDR and tactical-radio form factors.
Recomendado
PCI/PCI Express Endpoint Bridge
The EP3C120F780I7 implements a single-lane PCI Express endpoint or a 64-bit/66 MHz PCI bridge with its 119K logic elements comfortably, leaving 60-70% utilization for user application logic on the bus-master side. The 4 PLLs generate the 100 MHz PCIe reference and the 66 MHz PCI clock from a common source. The 531 I/Os handle the 64-bit PCI/PCI-X data bus, JTAG, and local-bus glue to DSPs and memories. The industrial temperature range covers blade-server mezzanine cards in unconditioned environments.
Recomendado
Machine Vision & Image Acquisition
Machine vision pipelines combining image preprocessing, color-space conversion, and feature extraction benefit from the EP3C120F780I7's 288 multipliers and 3.98 Mbits of block RAM. The 531 I/Os accept multi-lane Camera Link, MIPI-CSI-2 (with soft PHY), and parallel RGB sensor inputs at full throughput. The 4 PLLs generate the camera pixel clock, the processing clock, and an Ethernet-side clock for GigE Vision output. The -40C to +100C industrial grade supports factory-floor and outdoor inspection cameras. Altera's VIP and OpenCL SDKs accelerate image-pipeline development.

Notas de diseño
The EP3C120F780I7 requires multiple power rails: VCCINT 1.2 V for the core logic, VCCAUX 2.5 V for PLLs and configuration, VCCIO 1.2-3.3 V per I/O bank (8 banks), and VCCPD 3.3 V for the configuration I/O. Decoupling per the Altera Cyclone III reference design is 100 nF plus 10 µF bulk per power pin pair, with the placement within 50 mils of the BGA via. A bulk capacitor of 330 µF on VCCINT and 100 µF on VCCAUX is recommended to handle inrush during configuration.
The 780-ball FBGA uses 1.0 mm ball pitch on a 29x29 mm substrate, requiring a 6-layer PCB minimum with microvia-in-pad or via-in-pad technology for the inner-row escape. Signal fanout should use the dog-bone pattern from the BGA break-out layer to a 4-mil trace/space inner layer, with the top and bottom reserved for component placement and a solid ground/power plane. Differential pair length matching for LVDS must be within ±10 mil, and DDR/2 interface traces need ±25 mil matching with fly-by topology.
Configuration mode pins MSEL[3:0] must be set to the correct mode (e.g., 0000 for active serial, 0100 for passive parallel) before power-up; the wrong setting will prevent configuration. The nCONFIG pin must be held low during power-up to abort any spurious configuration attempts. Unused I/O banks should be tied to VCCIO through a 10 kΩ resistor and VREF pins left floating, per the Altera pin connection guidelines. JTAG TCK should be pulled to ground through 1 kΩ if unused to avoid noise-induced configuration attempts.
Información de cumplimiento
