Microchip Technology ATSAM3S8
ATSAM3S8 variants from Microchip Technology
ATSAM3S8 Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Footprint / package: 64-LQFPSingle 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.
- 3 distinct suffix patternsExamples: BA-AUR, CA-AU, CA-CU. 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 3 ATSAM3S8 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 |
|---|---|---|---|---|---|---|---|

Ordering Code Differences
How suffixes on ATSAM3S8 map to package, grade, and reel options.
How to Choose the Right ATSAM3S8 Microcontrollers
Match the footprint first
Packages here: 64-LQFP. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For ATSAM3S8, 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 "ATSAM3S8" — include the full suffix (e.g. BA-AUR, CA-AU, CA-CU). RFQ with reel/tube preference and required date code.
