EP3C40U484C7

The EP3C40U484C7 is a Cyclone III family FPGA in a 484-ball FBGA package, offering a balance of logic capacity, embedded memory, and I/O density for commercial designs. Built on the Cyclone III architecture, this device targets cost- and power-sensitive applications that require flexible programmable logic, moderate on-chip memory, and substantial I/O connectivity.

Key device-level characteristics include 39,600 logic elements, approximately 1.16 Mbits of embedded memory, 331 user I/Os, and a 1.15–1.25 V core supply window, making it suitable for compact, surface-mount system designs operating in commercial temperature ranges.

Key Features

• Logic Capacity  39,600 logic elements provide programmable logic resources to implement complex control, signal processing, and glue-logic functions.
• On-chip Memory  Approximately 1.16 Mbits of embedded memory to support buffering, lookup tables, and small data stores without external RAM.
• I/O Density  331 user I/Os for flexible peripheral interfacing, bus connections, and high-pin-count system requirements.
• Package & Mounting  484-FBGA package (supplier package: 484-UBGA, 19×19) in a surface-mount form factor for compact PCB designs.
• Power Supply  Core voltage range of 1.15 V to 1.25 V to match system power rails and achieve the family’s low-power operating profile.
• Operating Range & Grade  Commercial grade with an operating temperature range of 0 °C to 85 °C, suitable for standard commercial electronics.
• RoHS Compliance  Device is RoHS compliant for global electronics manufacturing requirements.
• Cyclone III Family Capabilities  Leverages Cyclone III architecture features such as low-power process technology, high memory-to-logic ratio, and multi-function clock management (family-level features described in the Cyclone III device handbook).

Typical Applications

• Portable and Handheld Devices  Low-power family characteristics and integrated memory make this device suitable for battery-powered or thermally constrained designs.
• Consumer and Industrial Interfaces  Use the device for user-interface control, bridging peripherals, and consolidating multiple discrete logic components.
• Communications and Networking  Implement protocol handling, buffering, and I/O adaptation where moderate logic density and high I/O count are required.
• Embedded Processing & Custom IP  Deploy embedded controllers or custom accelerators using available logic and on-chip memory, supported by the Cyclone III family IP ecosystem.

Unique Advantages

• Balanced Logic and Memory  39,600 logic elements combined with approximately 1.16 Mbits of embedded RAM enables a mix of control logic and data buffering on a single device.
• High I/O Count  331 I/Os simplify system-level integration by reducing external interface components and enabling direct connections to multiple peripherals.
• Compact Surface-Mount Package  484-FBGA (484-UBGA, 19×19) provides a high-density solution for space-constrained PCBs while maintaining robust connectivity.
• Commercial Temperature Suitability  Rated 0 °C to 85 °C to match the requirements of typical commercial electronics and embedded systems.
• RoHS-Compliant  Meets lead-free manufacturing requirements for modern electronics production.
• Supported Cyclone III Ecosystem  Benefits from Cyclone III family resources and pre-verified IP to accelerate design development and system integration.
