Microchip Technology AVR128DB
AVR128DB variants from Microchip Technology
AVR128DB Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Footprint / package: https://www.microchipdirect.com/product/search/all/AVR128DB28, https://www.microchipdirect.com/product/search/all/AVR128DB32, https://www.microchipdirect.com/product/search/all/AVR128DB48, https://www.microchipdirect.com/product/search/all/AVR128DB64Land 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.
- 7 distinct suffix patternsExamples: 28, 32, 48, 64, 28-E/SP (+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 AVR128DB Microcontrollers
Match the footprint first
Packages here: https://www.microchipdirect.com/product/search/all/AVR128DB28, https://www.microchipdirect.com/product/search/all/AVR128DB32, https://www.microchipdirect.com/product/search/all/AVR128DB48, https://www.microchipdirect.com/product/search/all/AVR128DB64. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For AVR128DB, 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 "AVR128DB" — include the full suffix (e.g. 28, 32, 48). RFQ with reel/tube preference and required date code.
