Microchip Technology 24AA64
24AA64 variants from Microchip Technology
24AA64 Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Footprint / package: 5-UFBGA, CSPBGASingle 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.
- 7 distinct suffix patternsExamples: I/SM, F-I/P, FT-I/OT, T-I/MNY, T-I/OT (+2 more). 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 24AA64 Microcontrollers
Match the footprint first
Packages here: 5-UFBGA, CSPBGA. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For 24AA64, 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 "24AA64" — include the full suffix (e.g. I/SM, F-I/P, FT-I/OT). RFQ with reel/tube preference and required date code.
