The 197 user I/O give you enough pins to route a parallel display bus, a DDR memory interface, and a handful of serial peripherals without multiplexing — useful when the board area is tight but the pin count still needs to breathe. ## Industrial temperature grade and single-rail core The core supply is a single 1.045-1.155 V rail, so you only need one clean 1.1 V regulator for the FPGA fabric, not a multi-rail sequencing headache.","metaTitle":"Lattice LFE5U-12F-6BG381I ECP5 FPGA, 12K LUTs, 197 I/O","metaDescription":"Lattice Semiconductor LFE5U-12F-6BG381I ECP5 FPGA with 12000 LUTs, 197 I/O, 589824 bits block RAM, 1.045-1.155V core, -40 to 100°C.","metaKeywords":null},"attributes":{"series":"ECP5","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["FPGA / CPLD & Programmable Logic"],"specifications":{"Mfr":"Lattice Semiconductor Corporation","Series":"ECP5","Package":"Tray","Mounting Type":"Surface Mount","Number of I/O":"197","Package / Case":"381-FBGA","Product Status":"Active","Total RAM Bits":"589824","lifecycle_stage":"unknown","Voltage - Supply":"1.045V ~ 1.155V","Base Product Number":"LFE5U-12","Number of LABs/CLBs":"3000","Operating Temperature":"-40°C ~ 100°C (TJ)","Supplier Device Package":"381-CABGA (17x17)","Number of Logic Elements/Cells":"12000"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$21.1000","priceTiers":[{"qty":1,"price":"$21.10000","currency":"USD"},{"qty":25,"price":"$18.45000","currency":"USD"},{"qty":100,"price":"$17.74500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/496575ee6a44fd98e19810ac630165b2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LFE5U-12F-6BG381I/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between LFE5U-12F-6BG381I and LFE5U-12F-8BG381I?","answer":"Both share the same 381-ball CABGA package, 12,000 logic cells, and 197 I/O. The -8BG381I carries a faster speed grade (-8 vs -6), which translates to tighter timing closure on the same design — if your design already meets timing on the -6, the -8 buys you margin; if you are pushing the fabric near its limit, the -8 may save a respin."},{"question":"Will LFE5U-12F-6BG381I drop into a board designed for LFE5U-12F-6BG256I?","answer":"No — the 381I uses a 381-ball CABGA (17x17 mm), while the 256I uses a 256-ball CABGA (14x14 mm). The ball pitch, footprint, and PCB layout are different. The logic fabric and I/O count are identical, but the board must be laid out for the larger package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/lattice-semiconductor-corporation/LFE5U-12F-6BG381I","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/lattice-semiconductor-corporation/LFE5U-12F-6BG381I when reusing this data.
