Lattice Semiconductor LC4256V
LC4256V variants from Lattice Semiconductor
LC4256V Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: 3FTN256BC, 5FTN256BI. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 2 LC4256V part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|
| LC4256V-3FTN256BC | EE PLD, 3ns, 256-Cell, CMOS, PBGA256, FTBGA-256 | Lattice Semiconductor | Active | Compliant | In Stock | |
| LC4256V-5FTN256BI | EE PLD, 5ns, 256-Cell, CMOS, PBGA256, FTBGA-256 | Lattice Semiconductor | Active | Compliant | In Stock |

How to Choose the Right LC4256V Microcontrollers
Match the footprint first
Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.
Electrical headroom
Compare voltage and current columns in the variant table. For LC4256V, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "LC4256V" — include the full suffix (e.g. 3FTN256BC, 5FTN256BI). RFQ with reel/tube preference and required date code.
