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 44 is recommended to verify programming.

Screening (Caution)

(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.
