Nordic Semiconductor NRF54LM
NRF54LM variants from Nordic Semiconductor
NRF54LM Overview
What changes between part numbers, and what to check before you lock the BOM — System on Chip (SoC).
Key Features
- Footprint / package: CSP98Single package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: 20A, 20B. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- System on Chip (SoC) — 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 NRF54LM part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| nRF54LM20A | Package: CSP98 | RAM: 512 KB | Operating Temperature: -40 to +85 ºC | Product Family: Product | Processor: 128 MHz Arm Cortex-M33 DSP, FPU | NVM: 2 MB | CSP98 | Nordic Semiconductor | Active | Compliant | In Stock | |
| nRF54LM20B | Package: CSP98 | RAM: 512 KB | Operating Temperature: -40 to +85 ºC | Product Family: Product | Processor: 128 MHz Arm Cortex-M33 DSP, FPU | NVM: 2 MB | CSP98 | Nordic Semiconductor | Active | Compliant | In Stock |
Ordering Code Differences
How suffixes on NRF54LM map to package, grade, and reel options.
How to Choose the Right NRF54LM System on Chip (SoC)
Match the footprint first
Packages here: CSP98. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For NRF54LM, 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 "NRF54LM" — include the full suffix (e.g. 20A, 20B). RFQ with reel/tube preference and required date code.
