Usage precaution

Usage precaution of built-in PROM version

(1) All built-in PROM versions

High voltage is required to program to the built-in PROM. Be careful not to apply excessive voltage.

Be especially careful during power-on.

(2) One Time PROM version

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.

Programming with PROM programmer

Screening (Note 1)

(Leave at 150˚C for 40 hours)

Verify test PROM programmer

ROM data check in all numbers, target device

(high temperature, low temperature) (Note 2) Vcc=5.5V, 5.0V, 4.5V

Note 1: Never expose to 150˚C exceeding 100 hours.

Note 2: Test in responce to using temperature limit.
