ROM PROGRAMMING METHOD

The built-in PROM of the blank One Time PROM version and the

EPROM version can be read or programmed with a general purpose

PROM programmer using a special programming adapter. Set the

address of PROM programmer in the user ROM area.

The PROM of the blank One Time PROM version is not tested or

screened in the assembly process and following processes. To en-

sure proper operation after programming, the procedure shown in

Figure 75 is recommended to verify programming.

Screening (Note)

(150°C for 40 hours)

Verification with

PROM programmer

Functional check in

target device

The screening temperature is far higher

than the storage temperature. Never

expose to 150 °C exceeding 100 hours.
