LFE2-12SE-6FN484C

The LFE2-12SE-6FN484C is an ECP2 family Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation. It delivers a mid-range programmable fabric with 12,000 logic elements and a high I/O count, packaged in a compact 484-ball BGA for surface-mount applications.

This device is suited for commercial embedded designs that require substantial I/O, on-chip memory for data buffering, and low-voltage core operation. Its combination of logic density, embedded RAM, and a dense BGA footprint enables integration of control, interface, and processing functions on a single device.

Key Features

• Logic Capacity — 12,000 logic elements provide the programmable resources needed for mid-density digital designs and custom logic implementations.
• Embedded Memory — Approximately 0.226 Mbits (226,304 bits) of on-chip RAM supports buffering, FIFOs, and small data structures without external memory.
• I/O Density — 297 available I/O pins enable complex interfacing, parallel buses, and multiple serial/parallel peripherals in a single FPGA.
• Power — Core voltage supply range of 1.14 V to 1.26 V to match modern low-voltage system rails.
• Package and Mounting — 484-FPBGA (23×23) / 484-BBGA package in a surface-mount form factor for space-constrained PCBs.
• Operating Range — Commercial temperature range of 0 °C to 85 °C for standard embedded and consumer applications.
• Compliance — RoHS compliant for environmental and manufacturing requirements.

Typical Applications

• Interface Bridging and Protocol Conversion — Use the high I/O count and programmable logic to implement parallel-to-serial bridges, protocol adaptation, and multi-bus interfacing.
• Embedded Control and Signal Processing — Implement custom control logic, state machines, and moderate-throughput signal processing using available logic elements and on-chip RAM.
• Communications and Networking Modules — Leverage the I/O density and embedded memory for packet buffering, framing, and peripheral conditioning in communications equipment.

Unique Advantages

• High Logic Density — 12,000 logic elements allow consolidation of multiple functions into a single FPGA, reducing board-level complexity.
• Significant On-chip Memory — Approximately 0.226 Mbits of embedded RAM supports local buffering and reduces dependence on external memory components.
• Extensive I/O — 297 I/O pins give flexibility to connect numerous peripherals and interfaces directly to the FPGA fabric.
• Compact, Surface-Mount BGA — The 484-ball FPBGA (23×23) footprint helps minimize PCB area while providing a high pin count for dense designs.
• Low-Voltage Core Compatibility — 1.14–1.26 V supply range accommodates modern low-voltage system architectures.
• RoHS Compliance — Meets common environmental and manufacturing standards for lead-free production.
