LFE5U-45F-7BG256C

Product Overview

The Lattice Semiconductor Corporation LFE5U-45F-7BG256C is an ECP5 field programmable gate array (FPGA) integrated circuit intended for embedded logic and programmable interconnect use. The device provides 44,000 logic elements or cells, 11,000 LABs/CLBs, and 1,990,656 total RAM bits, supporting configurable data paths and local memory structures within a programmable fabric. It offers 197 I/O pins and uses a 256-LFBGA surface-mount package. The supply voltage range is 1.045 V to 1.155 V, and the operating junction temperature range is 0°C to 85°C.

• 1,990,656 total RAM bits for on-device storage and buffering.
• 197 I/O pins for external interface connections.
• 256-LFBGA surface-mount package.
• 1.045 V to 1.155 V supply voltage range.
• 0°C to 85°C operating junction temperature range.

Applications

• Embedded control logic for custom state machines and peripheral sequencing.
• Programmable interface bridging between user-defined input and output signals.
• On-device data buffering and formatting using the RAM resources.
• Custom signal aggregation and routing in embedded systems.

Design & Procurement Notes

When selecting this part, verify that the system power rail can meet the 1.045 V to 1.155 V supply range and that board layout supports surface-mount 256-LFBGA assembly. The 197 I/O count should be checked against required external signal mapping, while the 44,000 logic elements/cells, 11,000 LABs/CLBs, and 1,990,656 RAM bits define the programmable fabric and on-chip memory capacity for design implementation. The 0°C to 85°C operating junction temperature range should be considered with thermal analysis for the final board and enclosure. The ECP5 series designation identifies the device family, but exact design constraints should be confirmed against the complete technical documentation for the part.
