Microchip Technology ATTINY20
ATTINY20 variants from Microchip Technology
ATTINY20 Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Footprint / package: 14-TSSOP (0.173", 4.40mm Width)Single 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.
- 5 distinct suffix patternsExamples: CCU, MMH, MMHR, SSUR, XUR. 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 5 ATTINY20 part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

How to Choose the Right ATTINY20 Microcontrollers
Match the footprint first
Packages here: 14-TSSOP (0.173", 4.40mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For ATTINY20, 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 "ATTINY20" — include the full suffix (e.g. CCU, MMH, MMHR). RFQ with reel/tube preference and required date code.
