LIFCL-40-8SG72C

The LIFCL-40-8SG72C is a CrossLink-NX™ Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation. It delivers approximately 39,000 logic elements and about 1.55 Mbits of embedded RAM in a compact 72-QFN (10×10) exposed-pad package.

This device is supplied as a surface-mount commercial-grade FPGA designed for applications that require flexible, on-chip programmable logic, dedicated I/O, and on-chip memory within a 0 °C to 85 °C operating range.

Key Features

• Logic Capacity  Approximately 39,000 logic elements to implement custom logic, state machines, and glue logic directly on-chip.
• Embedded Memory  Approximately 1.55 Mbits of on-chip RAM for buffering, LUT-based storage, and memory-intensive functions.
• I/O Count  40 dedicated I/O pins provide flexible interfacing options for peripheral connections and board-level signal routing.
• Low-Voltage Core  Core voltage supply range of 0.95 V to 1.05 V to support low-voltage system designs.
• Package & Mounting  72-VFQFN exposed pad, supplier package 72-QFN (10×10), optimized for surface-mount assembly and thermal conduction through the exposed pad.
• Commercial Temperature Grade  Rated for operation from 0 °C to 85 °C for commercial applications.
• Regulatory Compliance  RoHS-compliant material construction.

Typical Applications

• Programmable Logic Integration  Implement custom combinational and sequential logic functions where on-chip logic density and embedded RAM are required.
• I/O Control and Interface  Serve as a flexible interface controller using the 40 available I/O pins for signal conditioning, protocol bridging, or board-level glue logic.
• Embedded Memory-Centric Functions  Use the approximately 1.55 Mbits of RAM for buffering, packet queues, or small data-store functions within an FPGA-based design.

Unique Advantages

• High Logic Density:  Approximately 39,000 logic elements enable significant on-chip integration, reducing the need for external ASICs or multiple discrete devices.
• On-Chip Memory:  About 1.55 Mbits of embedded RAM supports memory-heavy tasks without adding external memory components.
• Compact, Thermally-Conscious Package:  72-VFQFN exposed pad (72-QFN, 10×10) provides a small PCB footprint while allowing thermal vias to the exposed pad for heat dissipation.
• Low-Voltage Core Support:  0.95 V–1.05 V supply enables integration into modern low-voltage power domains.
• Commercial Temperature Rating:  Rated 0 °C to 85 °C for standard commercial deployments.
• RoHS Compliant:  Meets RoHS requirements for use in lead-free assemblies.
