Power And Operating Modes

• Active current: Not characterized in seed; extract active current from datasheet tables.
• Sleep / standby current: Not characterized in seed; extract sleep/standby current from datasheet tables.
• Supply rails: EasyEDA property: 2.8V~5.25V.
• Notes: Seed values are search hints only. Verify power modes, rail limits, startup requirements, and reference design passives from the datasheet.

Procurement Classification

• JLC class: Extended Part
• JLC note / assembly basis: EasyEDA/JLC verified common memory, timing, storage, and security seed
• Assembly status: jlc_extended
• Price-break table: Not captured in seed. Store only timestamped price-break snapshots when intentionally refreshed.
• Live stock: intentionally not stored as durable selection data; refresh externally before ordering.

Selection Notes

• Good for: device identity, secure boot support, anti-cloning, key storage, certificate authentication, and 1-Wire or I2C authenticators
• Avoid when: Not captured yet.
• Known layout constraints: Verify package land pattern, decoupling requirements, thermal pad, RF keepouts, crystal routing, and boot straps from the datasheet.
• Equivalent search hints: match category secure-eeprom, interfaces 1-wire, package TDFN-6-EP(3x3), and EasyEDA footprint UUID 206b415751854605b13bc549a6f883e3.
