Microchip Technology ATTINY24A
ATTINY24A variants from Microchip Technology
ATTINY24A Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
ATTINY24A is a Microchip Technology order-code family — not a single orderable MPN. This page lists 7 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
| Official Price: 0.6300 | Official Product URL: https://www.microchip.com/en-us/product/ATtiny24A Other listed variants describe: IC MCU 8BIT 2KB FLASH 15UFBGA; IC MCU 8BIT 2KB FLASH 20QFN.
Across listed variants, watch these parameters: packages: 14-SOIC (0.154", 3.90mm Width).
Suffix examples in this family: CCU, MF, MUR, SSF, SSNR, SSU. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Example MPNs: ATTINY24A, ATTINY24A-CCU, ATTINY24A-MF, ATTINY24A-MUR, ATTINY24A-SSF, ATTINY24A-SSNR.
Key Features
- Footprint / package: 14-SOIC (0.154", 3.90mm 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.
- 6 distinct suffix patternsExamples: CCU, MF, MUR, SSF, SSNR (+1 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

Ordering Code Differences
How suffixes on ATTINY24A map to package, grade, and reel options.
ATTINY24A uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: CCU, MF, MUR, SSF, SSNR, SSU.
Full MPN examples: ATTINY24A-CCU, ATTINY24A-MF, ATTINY24A-MUR, ATTINY24A-SSF, ATTINY24A-SSNR.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right ATTINY24A Microcontrollers
Match the footprint first
Packages here: 14-SOIC (0.154", 3.90mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For ATTINY24A, 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 "ATTINY24A" — include the full suffix (e.g. CCU, MF, MUR). RFQ with reel/tube preference and required date code.
