BOM rule hits · not reviewed — A hit means a BOM line matched this category's rules (ruleset 1.0.1+12960cbec977). It is a lead to read, not a located or reviewed circuit; several lines in one category are not several circuits.
Selection parameter template (suggestion)
What one usually states when choosing a circuit of this kind — not the parameters of any design or module listed here, and never a filter.
| Parameter | Suggested range or common values | Where it comes from |
|---|---|---|
| Capacity (Mbit)Decisive | 0.001 to 65,536 Mbit | Inherited from Data storage |
| InterfaceDecisive | SPIQSPII2CParallel busSDIOeMMCDDR | Inherited from Data storage |
| Operating voltage (V)Important | 1.8 to 5 V1.83.3 | Inherited from Data storage |
| Maximum clock (MHz)Important | 0.4 to 200 MHz | Inherited from Data storage |
| Write endurance (cycles)For reference | 100,000 to 100,000,000,000,000 cycles | Inherited from Data storage |
