EP3C5E144C7N

The EP3C5E144C7N is a Cyclone III family FPGA in a 144-LQFP exposed-pad surface-mount package, offering 5,136 logic elements and approximately 0.4 Mbits of embedded memory. Designed for commercial-grade applications, this device provides a balance of logic capacity, on‑chip memory, and I/O density in a compact package.

Built on the Cyclone III device family architecture, the part targets low-power, cost‑sensitive designs that benefit from integrated clock management and flexible I/O. Typical use cases include portable and handheld systems, consumer electronics, embedded control, and communication interfaces that require a mid-range FPGA resource set.

Key Features

• Logic Capacity — 5,136 logic elements for implementing mid-range combinational and sequential logic.
• Embedded Memory — Total on-chip RAM of 423,936 bits (approximately 0.4 Mbits) for local buffering, state machines, and small data storage.
• I/O Resources — 94 device I/Os to support multiple interfaces and peripheral connections in space-constrained designs.
• Package and Mounting — 144-LQFP exposed pad (supplier package: 144-EQFP 20×20) with surface-mount construction for compact PCB layouts and thermal dissipation through the exposed pad.
• Power — Core voltage supply range from 1.15 V to 1.25 V to match system power rails and optimize power consumption.
• Operating Range — Commercial temperature grade rated from 0 °C to 85 °C for mainstream commercial environments.
• RoHS Compliant — Conforms to RoHS requirements for reduced hazardous substances.
• Cyclone III Family Capabilities — Leverages Cyclone III family features such as low‑power operation and advanced clock management (family supports up to four PLLs) for efficient system design and clocking flexibility.

Typical Applications

• Portable and Handheld Devices — Low-power family characteristics and compact LQFP packaging make the device suitable for battery‑sensitive handheld applications that require programmable logic.
• Consumer Electronics — Provides mid-range logic and memory for user interface control, peripheral glue logic, and feature integration in consumer products.
• Embedded Control and Instrumentation — Use as a customizable logic engine for sensor interfacing, control state machines, and local signal conditioning.
• Communications Interfaces — 94 I/Os allow implementation of multiple serial or parallel interfaces and protocol handling in communication modules and subsystems.

Unique Advantages

• Right-sized Logic and Memory: 5,136 logic elements and ~0.4 Mbits of embedded memory provide a balanced resource set for mid-range programmable designs without excessive overcapacity.
• Flexible I/O Count: Ninety-four I/Os enable multiple peripheral and interface connections while keeping PCB routing manageable.
• Compact, Thermally Aware Package: The 144-LQFP exposed pad supports surface-mount assembly and helps dissipate heat through the package underside for stable operation.
• Low-Voltage Core: 1.15 V–1.25 V core voltage support aligns with modern power rails to help manage system power budgets.
• Commercial Grade: Rated 0 °C to 85 °C for mainstream commercial deployments where proven, cost-effective FPGA functionality is required.
• RoHS Compliance: Meets environmental requirements for reduced hazardous materials in production and deployment.
