• Manufacturer: Mitsubishi

Usage precaution
Figure 1.24.1. Programming and test flow for One Time PROM version
Usage precaution of 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 (M30622ECTFP/ECVFP, M30623ECTGP/ECVGP), 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 pro-
cesses. To improve their reliability after programming, we recommend to program and test as flow
shown in Figure 1.24.1 before use.
But, in case of using as the test of cars loading, mass production, correspond to programming PROM,
and screened shipped in programming, please require.
