NXP Semiconductors LPC11U
LPC11U variants from NXP Semiconductors
LPC11U Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Footprint / package: 48-TFBGA, 32-VQFN Exposed PadLand pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 5 distinct suffix patternsExamples: 14FET48/201,, 14FHI33/201,, 24FET48/301,, 68JBD100K, 68JBD64K. 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

How to Choose the Right LPC11U Microcontrollers
Match the footprint first
Packages here: 48-TFBGA, 32-VQFN Exposed Pad. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LPC11U, 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 "LPC11U" — include the full suffix (e.g. 14FET48/201,, 14FHI33/201,, 24FET48/301,). RFQ with reel/tube preference and required date code.
