EP3C5E144I7

The EP3C5E144I7 is a Cyclone® III family Field Programmable Gate Array (FPGA) in a 144-LQFP exposed-pad package designed for industrial applications. It combines a mid-range logic capacity with embedded memory, flexible I/O and low-power family-level architecture to address cost- and power-sensitive control, signal processing and embedded system designs.

As part of the Cyclone III device family, the device leverages low-power process technology and FPGA architecture features such as on-chip memory, integrated PLLs and broad I/O support to simplify system integration in industrial environments.

Key Features

• Logic Capacity — 5,136 logic elements to implement combinational and sequential logic for mid-range applications.
• Embedded Memory — Approximately 0.4 Mbits (423,936 bits) of on-chip RAM for buffering, FIFOs and small data storage needs.
• I/O Count & Standards — 94 user I/Os with family-level support for a wide range of I/O standards and adjustable slew rates to improve signal integrity.
• Clock Management — Four phase-locked loops (PLLs) per device for robust clock synthesis and distribution, with dynamic reconfiguration capability at the family level.
• Low-Power Family Architecture — Based on Cyclone III low-power process and silicon optimizations to help meet power budgets in portable or thermally constrained systems.
• Package & Mounting — 144-LQFP exposed pad (supplier package: 144-EQFP, 20×20) in a surface-mount form factor for PCB assembly and thermal dissipation.
• Core Supply — Operates from a 1.15 V to 1.25 V core voltage range.
• Industrial Temperature Grade — Rated for operation from -40 °C to 100 °C.
• Compliance — RoHS compliant.
• Reliability Features — Family-level features include CRC/SEU detection circuitry and system-level upgrade paths to support long-term fielded designs.

Typical Applications

• Industrial Control — Implement motor control logic, timing, and custom state machines using mid-range logic capacity and industrial temperature range.
• Embedded Systems — Integrate control, peripheral glue logic and simple embedded processing functions using on-chip memory and the Cyclone III family’s embedded processor support.
• Communications & Interfaces — Support protocol bridging, interface adaptation and signal conditioning with plentiful I/Os and family-level support for diverse I/O standards.
• Sensor Processing & Data Aggregation — Buffer and preprocess sensor data locally using embedded RAM and programmable logic to reduce upstream processing load.
