Precaution for Handling One-Time-Programmable
Devices
Our company ships one-time-programmable version MCUs (One-
Time PROM MCU) without being screened by the PROM writing
test.
To ensure the reliability of the MCU, We recommend that the user
performs the program and test procedure shown in Figure 62
before using the MCU.

The screening temperature is far higher
than the storage temperature. Never
expose to 150 °C exceeding 100 hours.
