EP3C5U256I7

The EP3C5U256I7 is a Cyclone® III field-programmable gate array (FPGA) in a 256-LFBGA package optimized for low-power, cost-sensitive designs. Based on the Cyclone III device family architecture, this device combines moderate logic capacity, embedded memory, and a high I/O count to address portable, industrial, and high-volume applications where power efficiency and integration matter.

This industrial-grade device provides 5,136 logic elements, approximately 0.4 Mbits of embedded memory, 182 user I/Os, and an operating range of −40°C to 100°C, with a supply voltage window of 1.15 V to 1.25 V—delivering the core building blocks needed for compact, low-power systems.

Key Features

• Logic Capacity  5,136 logic elements provide the programmable fabric for mid-range control, glue logic, and custom logic functions.
• Embedded Memory  Approximately 0.4 Mbits of on-chip RAM supports buffering, FIFOs, and small data stores without external memory.
• I/O and Standards  182 user I/Os in a 256-LFBGA (256-UBGA 14×14) package enable flexible system interfacing; Cyclone III family devices support a broad set of I/O standards for mixed-signal interfaces.
• Clocking and Timing  Family-level clock management features include up to four PLLs per device for robust clock synthesis and distribution.
• Power Envelope  Designed on a TSMC low-power process with silicon and software optimizations to reduce static power consumption—suitable for energy-conscious designs within the specified 1.15 V to 1.25 V supply range.
• Package and Mounting  Surface-mount 256-LFBGA package (256-UBGA, 14×14) supports compact board layouts and high-density integration.
• Industrial Temperature Rating  Specified for operation from −40°C to 100°C for use in thermally challenging environments.
• Compliance  RoHS compliant.

Typical Applications

• Portable and Handheld Devices  Low static power characteristics and compact package support battery-powered products and thermally constrained designs.
• High‑Volume, Cost‑Sensitive Products  Mid-range logic and on-chip memory make the device suitable for cost-optimized mass production where integration reduces BOM cost.
• Industrial Control and Monitoring  Industrial temperature rating and flexible I/O support sensor interfacing, motor control logic, and embedded control functions.
• Embedded System Integration  On-chip memory, PLLs, and family support for embedded processors and IP cores enable system control and peripheral aggregation in compact designs.

Unique Advantages

• Low-Power Process Technology  Built on a low-power TSMC process with device- and software-level power optimizations to help meet tight power budgets.
• Balanced Integration  Combines moderate logic (5,136 LEs), embedded memory, and 182 I/Os to reduce external components and simplify PCB design.
• Robust Clock Management  Multiple PLLs at the family level enable flexible clock synthesis and distribution for diverse timing requirements.
• Industrial-Grade Operation  Rated from −40°C to 100°C for reliable operation in demanding thermal environments.
• Compact Packaging  256-LFBGA (14×14 UBGA) package supports high-density, space-constrained applications.
• Supported Development Ecosystem  Cyclone III family devices are supported by Quartus® II software and a wide collection of pre-built, verified IP cores to accelerate development.
