LFE2-20E-6FN484I

The LFE2-20E-6FN484I is an ECP2 Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation. It provides 21,000 logic elements, approximately 0.28 Mbits of embedded memory, and 331 user I/Os in a 484-ball BGA package.

Designed for industrial-grade applications, this device supports a low-voltage core supply (1.14 V to 1.26 V) and an extended operating temperature range of -40 °C to 100 °C, making it appropriate for systems that require substantial I/O count and on-chip memory in a compact surface-mount form factor.

Key Features

• Core Logic 21,000 logic elements provide the programmable fabric for implementing custom digital logic, state machines, and peripheral glue logic.
• Embedded Memory Approximately 0.28 Mbits of on-chip RAM for buffering, FIFOs, and small data structures without external memory components.
• I/O Density 331 user I/Os support extensive interfacing to peripherals, sensors, and external devices in a single device.
• Power Low-voltage core operation with a supply range of 1.14 V to 1.26 V to match modern low-voltage system rails.
• Package & Mounting 484-ball BGA (supplier device package: 484-FPBGA, 23×23) in a surface-mount form factor for high-density board designs.
• Industrial Temperature Range Rated for operation from -40 °C to 100 °C to meet industrial environmental requirements.
• Regulatory Compliance RoHS compliant for use in assemblies requiring lead-free, environmentally compliant components.

Unique Advantages

• Balanced integration: Combines a substantial logic element count with on-chip RAM and high I/O count to reduce external components and simplify system design.
• High I/O capacity: 331 I/Os enable complex interfacing and multiple concurrent peripheral connections from a single FPGA footprint.
• Compact BGA footprint: 484-ball FPBGA (23×23) packaging delivers high pin density in a compact surface-mount form, helping save PCB area.
