Altera EP3C80F484C7 is a Cyclone III field-programmable gate array (FPGA) providing 295 user I/O, 81,264 logic cells, 2,810,880 bits of memory, a 437.5 MHz stated frequency, and a 484-ball FBGA package. The device belongs to the FPGA > programmable logic > integrated circuit hierarchy and is designed for configurable digital logic, interface bridging, control processing, and embedded system prototyping. Its 65 nm technology and 1.2 V supply position it as a low-voltage programmable logic device for designs that require substantial logic capacity and high pin availability. An FPGA is a semiconductor integrated circuit containing configurable logic blocks, programmable interconnects, input/output resources, and memory elements. Unlike an application-specific integrated circuit, an FPGA can be electrically configured after PCB assembly. This makes it useful when a design requires rapid iteration, multiple interface protocols, parallel datapaths, or hardware functions that are not efficiently served by a fixed-function processor or controller. Cyclone III devices are part of the Altera programmable-logic family and are intended for cost-sensitive digital systems. The headline resource figures are 81,264 logic cells, 2,810,880 memory bits, 295 I/O, and 437.5 MHz stated frequency. These values indicate a device suitable for moderately complex control logic, communications interfaces, image or data preprocessing, and test equipment. The 484-ball FBGA package supports the high I/O count while using a surface-mount ball-grid-array format. The package designation must be checked against the PCB footprint and ball map before substitution because ball numbering and package orientation are critical. The supplied data identifies the device as a 65 nm FPGA operating at 1.2 V. It also identifies 5,079 LABs in one distributor result. The architecture is not described in the verified snippets, so detailed values for logic elements, embedded multipliers, phase-locked loops, transceiver count, operating temperature, speed grade, and thermal resistance are not asserted here. Those parameters should be confirmed from the manufacturer documentation or a current authorized source before design release. Typical applications include industrial control and automation, communications-interface aggregation, video or imaging preprocessing, test and measurement, and embedded digital signal processing. The 295 I/O resources can support multiple parallel interfaces, while the stated 437.5 MHz value provides a useful design target for timing analysis. Because programmable devices can be constrained by routing, I/O standards, memory bandwidth, power integrity, and tool configuration, system-level validation remains necessary. For design-in, verify the exact 484-ball FBGA footprint, power rails, configuration interface, supported I/O standards, bank restrictions, clocking resources, and recommended decoupling network from the manufacturer documentation. Treat the listed 1.2 V and 437.5 MHz values as verified device facts, but do not assume timing closure at that frequency in every design. The final design should include timing analysis, signal-integrity review, thermal analysis, and configuration-file validation. This product data combines verified distributor specifications, package and resource information, sourcing observations, and explicit uncertainty markers. It is intended to help engineers distinguish confirmed facts from parameters that require manufacturer-document verification, reducing the risk of assuming unsupported electrical or pin-level details.

Key features include 81,264 LEs for implementing soft processors and DSP datapaths, 295 user I/O pins for parallel buses and external memory interfaces, and 2.68 Mbit of on-chip RAM. DigiKey and Mouser list this part as a 484-BGA product with immediate availability. The FindIC aggregator lists a maximum internal clock frequency of 472.5 MHz, while the operating supply voltage range is 1.15 V to 1.25 V. This density is well suited for designs that require moderate logic capacity and high pin count but do not need the high-speed serial transceivers found on larger FPGAs. The FBGA-484 package provides a 1.0 mm ball pitch and 2.60 mm package height, which keeps PCB routing practical on a 4- to 6-layer board. The 295 user I/O pins can be assigned to multiple I/O banks with different voltage standards. For configuration, Cyclone III devices are typically paired with Altera serial configuration devices or download cables. The device's logic fabric is volatile and must be loaded from an external configuration source during power-up. Typical applications include industrial machine vision, broadcast video processing, telecom protocol bridging, medical imaging front-ends, and test-and-measurement instrumentation. These uses benefit from the 295-I/O capacity for parallel video buses and external SDRAM/DDR interfaces, the 81264 LEs for pixel processing, and the commercial temperature range for indoor equipment. When designing with this FPGA, pay careful attention to the core supply tolerance of 1.15 V to 1.25 V and to power sequencing. Decouple every power ball with ceramic capacitors close to the BGA, and use the manufacturer's power estimator to determine current demand at your actual utilization and clock rate.

The Quartus II / Quartus Prime design suite supports the entire Cyclone III family with synthesis, place-and-route, timing closure, and on-chip debug via SignalTap II. Typical applications include industrial motor control and machine vision, video processing and display controllers, telecommunications line cards and protocol bridging, automotive infotainment prototyping, test and measurement instrumentation, software-defined radio (SDR), and low-cost ASIC prototyping. The combination of high logic density and embedded multipliers makes the EP3C80 particularly suited for mid-range DSP pipelines and parallel data acquisition. When designing with this device, pay close attention to power supply sequencing - the 1.2 V core, 2.5 V PLL analog, and 3.3 V I/O rails must power up in the order specified by the datasheet to avoid latch-up. Use multiple decoupling capacitors (0.1 uF and 10 uF) near each power pin and keep configuration traces short to avoid bitstream loading errors.

Fabricated on a 60 nm TSMC low-k process, it supports up to 472 MHz internal operation and consumes roughly a quarter of the power of the prior Cyclone II generation. A Field Programmable Gate Array (FPGA) is a reconfigurable digital integrated circuit that combines programmable Look-Up Tables (LUTs), programmable interconnect, embedded block RAM, DSP blocks, and high-speed transceiver/PLL resources on a single die. FPGAs belong to the broader hierarchy: programmable logic -> logic IC -> integrated circuit. Compared with ASICs, FPGAs offer lower NRE cost, faster time-to-market, and field re-programmability, which is why engineers choose them for prototyping, low-volume production, and designs that need late-stage I/O or protocol updates. Key features of the EP3C80F780C8N include four phase-locked loops (PLLs), 244 embedded 18x18 multipliers (DSP blocks) suitable for moderate DSP workloads, and support for multiple I/O standards (LVDS, LVTTL, LVCMOS, SSTL, HSTL, PCI, PCI-X). It offers Nios II embedded processor support and is supported by the Quartus II design toolchain (Cyclone III device family). The 780-FBGA package has a 29x29 mm body, 1.0 mm ball pitch, and 2.60 mm height, easing PCB escape routing relative to finer-pitch BGA options. Typical applications span industrial motor control, video surveillance and image processing, automotive infotainment, telecom line cards, and handheld test equipment. Designers favor the Cyclone III family for its low static and dynamic power versus older families, which simplifies thermal budgets in fanless enclosures. When designing with this part, validate that the 1.0 mm pitch FBGA can be manufactured with your PCB fab's BGA capability. Use Quartus II 13.0sp1 or later for synthesis, and plan the decoupling network around the PLL analog supply pins (VCCA_PLL) with a 0.1 uF + 10 uF combination for jitter performance.

EP3C80F780C8NAF - Cyclone III FPGA 81K LE 780-BGA | Altera
The Altera EP3C80F780C8NAF is a Cyclone III family field-programmable gate array (FPGA) integrating 81,264 logic elements, 2,810,880 bits of embedded memory, and 4 PLLs into a 780-ball FineLine BGA package. Speed grade C8 and commercial temperature grade make it suited to cost-sensitive, high-volume digital logic designs where the proven Cyclone III architecture is preferred over newer families. A Field Programmable Gate Array (FPGA) is a semiconductor IC whose logic function is defined by a customer-supplied configuration bitstream rather than fixed at the fab. FPGAs occupy a distinct position in the digital design hierarchy: they sit above discrete logic ICs and below application-specific integrated circuits (ASICs), bridging the gap between software-like design flows and hardware-implemented performance. Cyclone III devices are low-power, low-cost SRAM-based FPGAs, with this variant falling into the higher-density tier of the family. Key features include 81,264 logic elements (LEs), 2,810,880 total RAM bits, 244 embedded 18x18 multipliers, 4 phase-locked loops (PLLs), and up to 429 user I/O pins. The 780-pin FineLine BGA exposes a wide I/O count, supporting multiple high-speed external memory interfaces and LVDS channels on a single die. Configuration is via the standard Altera active serial (AS), passive serial (PS), or JTAG paths. Typical applications include industrial motor and motion control, video processing pipelines, telecom baseband pre-processing, prototyping for ASICs, and embedded DSP for instrumentation. The C8 speed grade corresponds to an internal performance tier appropriate for parallel datapaths and moderate-clock peripherals rather than highest-frequency serial transceivers. When designing with this part, account for the SRAM-based configuration that requires a non-volatile boot device on every board. The 780-FBGA package also demands careful PCB layout, controlled-impedance routing, and power-rail sequencing; an accompanying Intel/Altera pinout should always be used. Plan JTAG access early to keep debug accessible on production boards.
