AT88SC Overview
What changes between part numbers, and what to check before you lock the BOM — general-purpose circuits.
AT88SC 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.
Package: 8-SOIC (0.154, 3.90mm Width) | Application: Embedded, Smart Card | Type: Secure Memory | Series: CryptoMemory® Other listed variants describe: Package: M2 J, Smart Card Module (ISO) | Mounting Type: Surface Mount | Type: Secure Memory | Supplier Device Package: M2 - J Module (ISO) | Applications: Embedded, Smart Card; Package: 8-UFDFN Exposed Pad | Mounting Type: Surface Mount | Type: Secure Memory | Supplier Device Package: 8-Mini Map (2x3) | Applications: Embedded, Smart Card.
Across listed variants, watch these parameters: packages: 8-SOIC (0.154, 3.90mm Width), M2 J, Smart Card Module (ISO), 8-UFDFN Exposed Pad.
Suffix examples in this family: 0104CA-SH-T, 0104C-MJ, 0104CA-Y6H-T, 0104CA-SH, 018-SU-CM, 0404CA-SH, 12816C-SU. 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.
Columns that actually vary on this page: Package Type. If two rows match on MPN prefix but differ there, they are not interchangeable for production.
Example MPNs: AT88SC0104CA-SH-T, AT88SC0104C-MJ, AT88SC0104CA-Y6H-T, AT88SC0104CA-SH, AT88SC018-SU-CM, AT88SC0404CA-SH.
Key Features
- Footprint / package: 8-SOIC (0.154, 3.90mm Width), M2 J, Smart Card Module (ISO), 8-UFDFN Exposed PadLand 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: 0104CA-SH-T, 0104C-MJ, 0104CA-Y6H-T, 0104CA-SH, 018-SU-CM (+2 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- general-purpose circuits — 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 AT88SC map to package, grade, and reel options.
AT88SC 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: 0104CA-SH-T, 0104C-MJ, 0104CA-Y6H-T, 0104CA-SH, 018-SU-CM, 0404CA-SH, 12816C-SU.
What changes between rows: Package Type. Sort the table by these columns when narrowing from base number to a single MPN.
Full MPN examples: AT88SC0104CA-SH-T, AT88SC0104C-MJ, AT88SC0104CA-Y6H-T, AT88SC0104CA-SH, AT88SC018-SU-CM.
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 AT88SC Variant
Match the footprint first
Packages here: 8-SOIC (0.154, 3.90mm Width), M2 J, Smart Card Module (ISO), 8-UFDFN Exposed Pad. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For AT88SC, 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 "AT88SC" — include the full suffix (e.g. 0104CA-SH-T, 0104C-MJ, 0104CA-Y6H-T). RFQ with reel/tube preference and required date code.
