Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- STANDBY MODE: The AT24C01A/02/04/08A/16A features a low-power standby mode which is enabled: (a) upon power-up and (b) after the receipt of the STOP bit and the completion of any internal operations.
- Sequential Read** 0180Z–SEEPR–11/06 5.5V range, please refer to performance values in the AC and DC characteristics table.
- Refer to JEDEC Drawing MS-012, Variation AA for proper dimensions, tolerances, datums, etc.
- Refer to JEDEC Drawing MO-153, Variation AA, for proper dimensions, tolerances, datums, etc.

Engineering review checklist
- Confirm supply rails, clock limits, memory size, peripheral mapping and I/O voltage compatibility.
- Check package pinout, boot configuration, programming interface and silicon-revision errata.
- Budget decoupling, thermal margin, startup timing and firmware recovery behavior before release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
