(6) Notes on handling
A high-voltage is used for writing. Take care that overvoltage
is not applied. Take care especially at turning on the power.
For the One Time PROM version, Mitsubishi Electric corp.
does not perform PROM writing test and screening in the
assembly process and following processes. In order to
improve reliability after writing, performing writing and test
according to the flow shown in Figure 32 before using is
recommended.

Note:
Screening (Leave at 150 °C for 40 hours) (Note)
blank
Since the screening temperature is higher
than storage temperature, never expose the
microcomputer to 150 °C exceeding 100
hours.
