LFE5U-12F-7TG144C

The LFE5U-12F-7TG144C is an ECP5 Field Programmable Gate Array (FPGA) offered in a 144-pin LQFP package for commercial applications. It provides a balanced combination of programmable logic resources, embedded memory, and a substantial number of user I/Os for compact, reconfigurable system designs.

With 12,000 logic elements, approximately 0.59 Mbits of on-chip RAM, and 98 I/O pins, this device targets designs that require moderate logic capacity, significant embedded memory, and flexible interfacing in a surface-mount 144-pin package. The device is RoHS compliant and rated for commercial temperature operation.

Key Features

• Logic Resources — 12,000 logic elements and 3,000 CLBs provide the programmable fabric needed for custom logic, glue-logic and protocol implementation.
• Embedded Memory — Approximately 0.59 Mbits (589,824 bits) of on-chip RAM for FIFOs, buffers, and temporary data storage without external memory.
• GPIO and Interface Capacity — 98 user I/O pins to support multiple external interfaces, sensors, and peripheral connections.
• Power — Core supply specified from 1.045 V to 1.155 V to match system power-rail design requirements.
• Package and Mounting — Available in a 144-LQFP package (supplier device package listed as 144-TQFP 20×20); surface-mount mounting for PCB assembly.
• Operating Range and Grade — Commercial grade device rated for 0 °C to 85 °C operating temperature.
• Compliance — RoHS compliant for lead-free manufacturing processes.

Typical Applications

• Commercial Embedded Systems — Implement custom control logic, protocol bridging, and peripheral management where a reprogrammable logic device and moderate I/O count are required.
• Data Buffering and Logic Acceleration — Use the on-chip RAM and logic elements for buffering, packet handling, or offloading repetitive logic tasks from a host processor.
• Interface Concentration — Consolidate multiple sensor, GPIO, or peripheral interfaces into a single FPGA-based hub using the available 98 I/Os.

Unique Advantages

• Balanced Logic and Memory: 12,000 logic elements paired with ~0.59 Mbits of RAM provide a versatile platform for medium-complexity designs requiring local storage.
• Generous I/O Count: Ninety-eight user I/Os enable flexible interfacing to multiple peripherals without immediate need for external multiplexers.
• Compact, Surface-Mount Packaging: 144-LQFP (144-TQFP 20×20) package supports PCB space-constrained designs while remaining compatible with standard surface-mount assembly processes.
• Controlled Core Voltage Range: Defined supply range (1.045 V–1.155 V) simplifies power-supply planning and integration into regulated systems.
• RoHS Compliant: Meets lead-free requirements for environmentally conscious manufacturing.
• Commercial Temperature Rating: Rated for 0 °C to 85 °C for general-purpose commercial environments.
