EP3C40U484C8N

The EP3C40U484C8N is a Cyclone® III family field programmable gate array (FPGA) in a 484-FBGA package designed for commercial-grade applications. It integrates 39,600 logic elements, approximately 1.16 Mbits of embedded memory, and 331 user I/Os to address high-density logic, moderate embedded memory, and rich I/O requirements.

Built on the Cyclone III device family architecture, this device targets high-volume, low-power, and cost-sensitive markets where on-chip integration, flexible clocking, and diverse I/O support improve system-level design efficiency.

Key Features

• Logic Capacity — 39,600 logic elements provide substantial combinational and sequential resources for mid-range FPGA designs.
• Embedded Memory — Approximately 1.16 Mbits of on-chip RAM for buffering, FIFOs, and data storage close to logic.
• I/O Resources — 331 user I/Os to support broad connectivity and multiple interface domains on a single device.
• Clock Management — Cyclone III family architecture includes up to four PLLs per device with five outputs each for flexible clock synthesis and phase control.
• Package & Mounting — 484-FBGA (484-UBGA, 19×19) surface-mount package suitable for dense PCB layouts.
• Supply & Temperature — Core voltage range of 1.15 V to 1.25 V and commercial operating temperature range of 0 °C to 85 °C.
• Low-Power Family Architecture — Cyclone III family emphasizes low power through process and architecture choices to support thermally constrained designs and extended battery life in portable applications.
• I/O Standards & Signal Integrity — Family-level support for a wide range of I/O standards and adjustable slew rates, plus features such as on-chip termination calibration to address PVT variations.
• Compliance — RoHS compliant.

Typical Applications

• Portable and Handheld Devices — Low-power family architecture and compact 484-FBGA package make the device suitable for battery-powered and space-constrained systems.
• Consumer and Industrial Controls — Abundant logic elements, embedded memory, and 331 I/Os enable motor control, sensor aggregation, and user-interface management.
• Communications and I/O Bridging — Multiple I/Os and flexible clocking fit protocol bridging, I/O expansion, and interface consolidation tasks.
• Embedded System Integration — On-chip RAM, clock management, and family support for embedded processors (Nios II on the family) allow tight integration of control and data-path logic.

Unique Advantages

• Substantial Logic Density: 39,600 logic elements enable implementation of mid-range logic designs without external glue logic, reducing board complexity.
• High I/O Count: 331 user I/Os allow direct connection to multiple peripherals and high-pin-count interfaces, minimizing the need for external I/O expanders.
• Integrated Memory: Approximately 1.16 Mbits of embedded RAM keeps data paths on-chip for lower latency and simpler PCB routing.
• Flexible Clocking: Up to four PLLs with multiple outputs provide on-chip clock synthesis and phase control to simplify timing architectures.
• Commercial Temperature and RoHS Compliance: 0 °C to 85 °C rating with RoHS compliance supports mainstream commercial production and environmental requirements.
• Compact, Surface-Mount Packaging: 484-FBGA (19×19) package balances pin count and board area for dense, manufacturable designs.
