EP3C80U484I7

The EP3C80U484I7 is an Intel Cyclone III FPGA in a 484-FBGA package designed for low-power, cost-sensitive applications requiring substantial logic and embedded memory. Built on the Cyclone III device family architecture, it provides a balance of integration, low power operation, and configurable I/O that suits embedded systems, communications interfaces, and portable or thermally constrained designs.

This device targets designs that need dense programmable logic (81,264 logic elements) and on-chip memory while operating across an industrial temperature range and a low core voltage domain.

Key Features

• Logic Capacity — 81,264 logic elements for implementing complex custom logic and state machines.
• Memory — Approximately 2.81 Mbits of embedded memory (total RAM bits: 2,810,880) to support buffering, FIFOs, and on-chip data storage.
• I/O Density — 295 I/O pins to support multiple external interfaces and parallel data paths.
• Clock Management — Family-level support for four phase-locked loops (PLLs) per device for clock synthesis and distribution (Cyclone III device family feature).
• Low-Power Operation — Cyclone III family design emphasis on low static power, suitable for power-sensitive and battery-powered applications.
• Embedded Processing Ecosystem — Supports the Cyclone III family ecosystem, including the Nios II embedded processor (family-level capability).
• Power and Temperature — Core supply range 1.15 V to 1.25 V and industrial operating temperature range from −40 °C to 100 °C.
• Package & Mounting — 484-FBGA (supplier package: 484-UBGA 19 × 19) for surface-mount assembly in compact PCBs.
• RoHS Compliant — Meets RoHS environmental requirements.

Typical Applications

• Battery-powered and portable equipment — Low static power characteristics and a low core-voltage range make the device suitable for designs where energy efficiency extends operating life.
• Embedded control and custom logic — Large logic element count and on-chip memory allow implementation of custom accelerators, protocol handling, and control logic.
• High I/O interface bridging — 295 I/O pins support interfacing between multiple peripherals, buses, or sensor arrays in medium-density systems.
• Thermally constrained and industrial systems — Rated for −40 °C to 100 °C operation to meet industrial temperature requirements.
• Clock-critical designs — Multiple PLLs and Cyclone III family clock-management features help implement robust timing architectures.

Unique Advantages

• Substantial programmable fabric: 81,264 logic elements provide headroom for complex state machines, datapaths, and interface logic without an external ASIC.
• On-chip memory for buffering: Approximately 2.81 Mbits of embedded RAM reduces reliance on external memory for many streaming and buffering tasks.
• Flexible I/O count: 295 I/O pins enable multiple parallel interfaces and dense connectivity on a single device.
• Industrial temperature rating: Operation from −40 °C to 100 °C supports deployment in industrial and harsh-environment installations.
• Compact board footprint: 484-FBGA 19 × 19 package allows high integration while saving PCB area and simplifying routing.
• Family ecosystem: Access to Cyclone III family features such as low-power design flow, PLL-based clock management, and Nios II support eases system-level development.
