EP3C80F484C7 - 295 I/O Cyclone III FPGA | Altera
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.

In the component taxonomy, this device is an FPGA, which is a programmable logic device, an integrated circuit, and a digital semiconductor product. Cyclone III FPGAs are positioned as low-cost, high-volume programmable logic for applications where ASSPs do not provide enough customization. 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.

As a member of the Cyclone III family, it targets cost-sensitive, power-conscious high-volume applications that require high logic density and rich memory resources. What is an FPGA? A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) belonging to the semiconductor integrated circuit hierarchy. It contains an array of configurable logic blocks (CLBs), programmable interconnects, embedded memory blocks, multipliers, and I/O cells. After manufacturing, the FPGA's function is defined by a user-supplied configuration bitstream loaded into SRAM-based configuration cells. In the broader system hierarchy, an FPGA sits between standard programmable logic (CPLD) and full Application-Specific Integrated Circuits (ASIC) - offering ASIC-like performance and parallelism with the flexibility of in-system reprogrammability. Key features include 81,264 logic elements arranged in a fabric of M9K memory blocks totaling 2,810,880 RAM bits, 244 embedded 18x18 multipliers, four general-purpose PLLs per device, and 429 maximum user I/O supporting multiple I/O standards (LVDS, LVCMOS, SSTL, HSTL).

Verified distributor data identifies a 437.5 MHz maximum clock, 1.2 V supply, 65 nm process technology, and a commercial temperature grade. The device is listed for sale by DigiKey and Mouser, while the verified search snapshot reports same-day shipping from DigiKey. An FPGA is a programmable semiconductor whose logic, interconnects, and I/O behavior can be configured after manufacturing. Within the component hierarchy, it belongs to programmable logic devices and field-programmable gate arrays. Unlike a fixed-function application-specific integrated circuit, an FPGA supports iterative logic changes without fabricating a new integrated circuit, making it useful for digital design, prototyping, interface bridging, and configurable control systems. The headline resources are 81,264 cells, 2,810,880 embedded-memory bits, and 295 I/O. These resources support datapaths, state machines, communications controllers, and peripheral interfaces. The 437.5 MHz value represents a verified maximum-clock listing and should be interpreted within the device's stated configuration and operating conditions. The 1.2 V core supply reflects the listed Cyclone III architecture. The part uses a 65 nm process and is supplied in a rectangular 484-terminal FBGA, also identified as UBGA or BGA-484 by distributor and comparison sources. The high terminal count supports 295 user I/O plus dedicated power, configuration, clock, and other device functions. Surface-mount assembly, controlled-impedance routing, and appropriate decoupling are therefore central to reliable implementation. Typical applications include industrial control, communications equipment, video or imaging interfaces, test equipment, and embedded processing systems. Its logic capacity suits multiple control blocks and interface functions, while the large I/O count helps connect memories, converters, network transceivers, and application-specific peripherals. Engineers must confirm timing closure, configuration storage, power sequencing, and supported I/O standards in the manufacturer datasheet. A key design trade-off is that adding programmable logic does not remove implementation effort. Clock budgets, pin assignments, power integrity, signal integrity, and thermal behavior must be analyzed for the final design. Logic capacity and I/O count alone do not guarantee a particular maximum system clock, because routing, constraints, tool settings, and peripheral interfaces affect timing. This page consolidates the verified distributor specifications, commercial availability, package identity, datasheet location, applications, and cross-reference evidence. Because no verified five-item set of same-footprint, pin-to-pin FPGA replacements was provided, alternatives are limited to candidates that can be supported without fabricating cross-brand or cross-package claims.

This page synthesizes distributor pricing, drop-in alternatives from the same Cyclone III family, and practical design notes not aggregated on a single manufacturer page.
EP3C80U484I7 - 81K LE Cyclone III FPGA, 484-FBGA | Intel
The Intel (formerly Altera) EP3C80U484I7 is a Cyclone III field-programmable gate array (FPGA) delivering 81,264 logic elements, 2,810,880 bits of embedded memory, and 295 user I/O pins in a 484-ball FineLine BGA (UBGA-484) package. As the largest device in the Cyclone III family, it targets low-cost, low-power, high-volume applications including digital signal processing, video processing, and industrial control. The industrial temperature grade (-40C to +85C) and 1.2 V core operation make it well suited for fanless embedded designs. A Field-Programmable Gate Array (FPGA) is a semiconductor device built around a matrix of configurable logic blocks (CLBs) connected via programmable interconnect. The hierarchy is: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit. Unlike fixed-function ASICs, FPGAs are reprogrammed in-circuit to implement custom digital logic, DSP pipelines, or soft-processor cores. Cyclone III sits at the low-power, low-cost end of Intel's FPGA portfolio, balancing density with low static and dynamic power consumption. Key features of the EP3C80U484I7 include 4 embedded PLL blocks (with up to 4 outputs per PLL) for clock synthesis and skew management, dedicated 18x18 hardware multipliers supporting DSP operations, 274 M9K memory blocks for distributed RAM and FIFO buffers, and a rich set of high-speed LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards. The device also provides a complete configuration subsystem including JTAG (IEEE 1149.1), Active Serial (AS), Passive Serial (PS), and Fast Passive Parallel (FPP) interfaces. Per the Altera Cyclone III Device Handbook, the device supports 1.0 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V LVCMOS/LVTTL I/O standards with hot-socketing capability. Typical applications span industrial motor control, video surveillance encoders, software-defined radio (SDR) baseband, telecom line cards, automotive infotainment pre-processing, medical imaging front-ends, and military/aerospace signal processing prototypes. The 484-FBGA FineLine BGA package provides a 19 x 19 mm footprint with 0.8 mm ball pitch, enabling dense PCB layouts with multiple signal layers. When designing with this device, ensure the JTAG chain is correctly terminated and that configuration flash (such as EPCS16 or EPCS64) is selected to match the bitstream size of the EP3C80. Quartus II (legacy) or Intel Quartus Prime Lite (current) software is the required design toolchain.
