Figure 1.19.1. Programming and test flow for One Time PROM version
Built-in PROM version
(1) All built-in PROM versions
(2) One Time PROM version
High voltage is required to program to the built-in PROM. Be careful not to apply excessive voltage.
Be especially careful during power-on.
One Time PROM versions shipped in blank (M30623ECGP, M30621ECGP), of which built-in PROMs
are programmed by users, are also provided. For these microcomputers, a programming test and
screening are not performed in the assembly process and the following processes. To improve their
reliability after programming, we recommend to program and test as flow shown in Figure 1.19.1
before use.
Note: Never expose to 150˚C exceeding 100 hours.
