EP3C40F484C8

The EP3C40F484C8 is a Cyclone III family FPGA offering a high-functionality, low-power programmable fabric in a compact 484‑BGA package. Designed for cost-sensitive, high-volume applications, this device delivers 39,600 logic elements and approximately 1.16 Mbits of embedded memory for mid-range logic and memory integration.

As a member of the Cyclone III family, it leverages low-power process technology and family-level features such as advanced clock management and flexible I/O support to help designers balance performance, power and system integration.

Key Features

• Core Logic — 39,600 logic elements provide the capacity for mid-range digital logic, custom peripherals and glue-logic integration.
• Embedded Memory — Approximately 1.16 Mbits of on-chip RAM to implement FIFOs, buffers, and local data storage without external memory.
• I/O Density — 331 user I/Os to support multiple interfaces and parallel buses in a single device.
• Clock Management — Cyclone III family-level clocking includes multiple PLLs for robust clock synthesis, distribution and phase control (family documentation specifies four PLLs per device).
• Power and Voltage — Core supply range of 1.15 V to 1.25 V supports low-power operation consistent with Cyclone III low-power design goals.
• Package & Mounting — 484‑BGA package (supplier device package: 484‑FBGA 23×23) with surface-mount mounting for compact, high-density PCB designs.
• Operating Range & Grade — Commercial grade device rated for 0 °C to 85 °C operation, suitable for a broad range of consumer and commercial applications.
• Regulatory — RoHS compliant.
• Family-Level Interface Support — Cyclone III family supports a wide range of I/O standards (for example: LVTTL, LVCMOS, SSTL, HSTL, PCI, PCI‑X, LVPECL, BLVDS, LVDS, mini‑LVDS, RSDS and PPDS), enabling flexible interface choices as documented in the device family handbook.

Typical Applications

• Portable and Handheld Devices — Low-power family characteristics help extend battery life and reduce cooling requirements in space- and power-constrained designs.
• Consumer Electronics — Use for display controllers, user-interface logic, and peripheral bridging where mid-range logic density and on-chip memory reduce BOM complexity.
• Communication and Networking — Implement protocol framing, packet buffering and custom I/O interfacing using the device’s logic capacity and embedded RAM.
• Instrumentation and Test Equipment — Combine flexible I/O and clock management to implement custom measurement front-ends and data aggregation logic.

Unique Advantages

• Balanced Logic and Memory: 39,600 logic elements paired with approximately 1.16 Mbits of embedded RAM let you implement substantial logic plus local buffering without adding external memory.
• High I/O Count: 331 user I/Os enable integration of multiple interfaces and parallel buses on a single FPGA, simplifying board-level design.
• Compact, Surface‑Mount Package: 484‑FBGA (23×23) provides a small-footprint solution for space-constrained PCBs while supporting high I/O density.
• Low‑Power Family Attributes: Cyclone III family low-power process technology and power-aware design features help reduce system power consumption in portable and thermally-challenged environments.
• Robust Clocking: Family-level multiple PLLs and flexible clock features facilitate complex timing, multi-domain designs and interfacing with diverse external clocks.
• Commercial-Grade Reliability: Rated for 0 °C to 85 °C operation and RoHS compliant for broad commercial applications.
