Description
Divide nonnegative cycles by positive writesPerDay for days.
A write-cycle budget divided by a write rate gives a nominal time budget. Real nonvolatile-memory endurance also depends on operating conditions and how writes are distributed.
Divide nonnegative cycles by positive writesPerDay for days.
When to use this tool
Use Eeprom Endurance Write Rate Life Term when you need a transparent supplied-cycle lifetime term.
How to use the tool and how it works
- Enter cycles, writesPerDay. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read days. Use the output convention below.

| Input field | Meaning and units | Accepted input |
|---|---|---|
| cycles | Cycles | Required. Safe integer; minimum 0. |
| writesPerDay | Writes Per Day | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| days | Days | Required. Finite number. |

}Limitations and assumptions
- Cycles and write rate are supplied; wear leveling, temperature, retention, and statistical device lifetime are not modeled.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Consult device endurance and retention specifications and model the actual write distribution and environment.
