Temperature at writing/erasing

Average temperature TA=+85°C*3

*1: The guaranteed value for erase up to 100,000 cycles

*2: Number of erase cycles for each sector

*3: This value comes from the technology qualification (using Arrhenius equation to translate high

temperature measurements into normalized value at + 85°C).

Notes:

−

While the Flash memory is written or erased, shutdown of the external power supply (VCC, VDD) is

prohibited.

−

In the application system where VCC or VDD might disappear while writing, be sure to turn the power

off by using an external low-voltage detector and NMIX pin + RSTX pin for reset input at same time.

Concretely, please execute two of the following.

1. After simultaneous input from the NMIX and RSTX pins while VDD is within the recommended

operating range, maintain VDD within the recommended operating range for at least 60 µs.

2. After simultaneous input from the NMIX and RSTX pins while VCC is within the recommended

operating range, power off VCC in observance of the standard regarding the supply voltage

fluctuation rate of the external low-voltage detector.
