LFE2-20SE-5F484C

The LFE2-20SE-5F484C is an ECP2 Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation, offered in a 484-ball BGA package. It provides reconfigurable digital logic resources with a combination of 21,000 logic elements, approximately 0.283 Mbits of embedded memory and a high I/O count for commercial embedded designs.

Designed for surface-mount applications running at commercial temperatures, this device targets designs that require moderate logic capacity, substantial I/O connectivity and low-voltage operation.

Key Features

• Core Logic  21,000 logic elements (cells) to implement custom digital logic and control functions.
• Embedded Memory  Approximately 0.283 Mbits of on-chip RAM for buffering, FIFOs and small data storage needs.
• I/O Capacity  331 user I/O pins to support a wide range of external interfaces and parallel connectivity.
• Power and Voltage  Nominal supply voltage range of 1.14 V to 1.26 V for device core power.
• Package and Mounting  484-BBGA package (supplier package: 484-FPBGA, 23×23) designed for surface-mount assembly to save PCB area.
• Operating Range  Commercial temperature rating from 0 °C to 85 °C, suitable for standard commercial electronic applications.
• Environmental Compliance  RoHS compliant for regulatory and manufacturing requirements.

Typical Applications

• Commercial Embedded Systems  Implement control logic and protocol handling where 21,000 logic elements and 331 I/Os meet system requirements.
• Interface Bridging  Use available I/O and on-chip RAM to manage multiple parallel or serial interfaces between subsystems.
• Custom Logic Acceleration  Offload deterministic or latency-sensitive tasks to reconfigurable logic implemented within the FPGA fabric.

Unique Advantages

• Substantial Logic Capacity:  21,000 logic elements provide room for mid-size logic designs without moving to larger device families.
• High I/O Count:  331 I/Os enable complex interfacing and direct connections to multiple peripherals or external components.
• On-Chip Memory:  Approximately 0.283 Mbits of embedded RAM supports buffering and small data storage needs without external memory.
• Compact BGA Footprint:  484-BBGA (23×23) packaging allows dense PCB layouts while maintaining robust ball-grid connectivity.
• Low-Voltage Core:  1.14 V–1.26 V supply range supports designs optimized for low-voltage power domains.
• Regulatory Compliance:  RoHS compliance supports environmentally conscious manufacturing requirements.
