LFE2-12SE-5FN484C

The LFE2-12SE-5FN484C is a field programmable gate array (FPGA) from Lattice Semiconductor Corporation’s ECP2 family. It provides 12,000 logic elements and on-chip RAM to implement mid-range programmable logic in commercial embedded designs.

With a 1.14 V to 1.26 V core supply range, 297 user I/Os, and a 484-ball BGA package, this device is aimed at commercial applications that require a balance of integration, I/O capacity, and compact surface-mount packaging.

Key Features

• Core Logic  12,000 logic elements for implementing combinational and sequential logic functions in mid-range designs.
• On-Chip Memory  Total on-chip RAM of 226,304 bits (approximately 0.226 Mbits) to support embedded buffering and state storage.
• I/O Capacity  297 user I/Os provide a high pin count for interfacing to peripherals, sensors, and system buses.
• Power  Core supply voltage ranges from 1.14 V to 1.26 V to match target system power domains and enable consistent core operation.
• Package & Mounting  484-ball BGA (supplier package: 484-FPBGA, 23 × 23) in a surface-mount form factor for compact PCB integration.
• Operating Conditions  Commercial-grade device with an operating temperature range of 0 °C to 85 °C.
• Environmental Compliance  RoHS compliant for regulatory and manufacturing considerations.

Typical Applications

• Commercial Embedded Systems  Implement mid-range control and logic functions where up to 12,000 logic elements and on-chip RAM are required.
• High‑Pin‑Count I/O Interfaces  Use the 297 I/Os for designs that require extensive peripheral connectivity or multiple bus interfaces.
• Compact Surface‑Mount Designs  The 484-BBGA package and surface-mount mounting simplify integration into space-constrained PCBs.

Unique Advantages

• Balanced Logic and Memory:  12,000 logic elements combined with approximately 0.226 Mbits of on-chip RAM support a wide range of mid-range logic and buffering needs without immediate reliance on external memory.
• High I/O Count:  297 user I/Os enable dense peripheral and bus connections, reducing the need for external multiplexing in many designs.
• Compact, Headerless Packaging:  484-ball BGA (23 × 23) keeps board footprint compact while providing the necessary ball count for complex designs.
• Commercial Temperature and Compliance:  Commercial-grade operation from 0 °C to 85 °C with RoHS compliance supports standard manufacturing and deployment requirements.
• Defined Core Voltage Range:  A specified core supply range of 1.14 V to 1.26 V supports consistent power planning during system design.
