LFE2-12E-5FN484C

The LFE2-12E-5FN484C is a Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation. It provides 12,000 logic elements, approximately 0.226 Mbits of on-chip RAM, and up to 297 I/O in a compact 484-ball BGA package.

With a 1.14 V to 1.26 V core supply and a commercial operating temperature range of 0 °C to 85 °C, this device is suited to designs that require moderate-density programmable logic, embedded memory, and a high I/O count in a surface-mount form factor.

Key Features

• Core / Logic 12,000 logic elements for implementing custom digital logic and control functions.
• Embedded Memory 226,304 bits of on-chip RAM (approximately 0.226 Mbits) for buffering, FIFOs, and small data stores.
• I/O 297 general-purpose I/O pins to support extensive peripheral and interface connectivity.
• Power Core voltage supply range of 1.14 V to 1.26 V to match low-voltage system architectures.
• Package & Mounting 484-BBGA package (supplier device package: 484-FPBGA, 23×23) in a surface-mount format for space-constrained board layouts.
• Operating Range & Grade Commercial grade device rated for 0 °C to 85 °C operation.
• Environmental Compliance RoHS compliant.

Typical Applications

• Custom Digital Logic Implement application-specific state machines, protocol handlers, and glue logic using the device's 12,000 logic elements.
• High-Density I/O Control Use the 297 I/O pins for parallel interfaces, bus bridging, or multi-channel I/O aggregation.
• On-Chip Memory Acceleration Leverage the embedded RAM for data buffering, small lookup tables, and packet or frame buffering.
• Compact, Surface-Mount Designs The 484-BBGA surface-mount package fits designs that require a high-pin-count FPGA in a compact footprint.

Unique Advantages
