DATA REQUIRED FOR MASK ORDERS
The following are necessary when ordering a mask ROM produc-
tion:
1.Mask ROM Order Confirmation Form
2.Mark Specification Form
3.Data to be written to ROM, in EPROM form (three identical cop-
ies)
DATA REQUIRED FOR ROM WRITING
ORDERS
The following are necessary when ordering a ROM writing:
1.ROM Writing Confirmation Form
2.Mark Specification Form
3.Data to be written to ROM, in EPROM form (three identical cop-
ies)
ROM PROGRAMMING METHOD
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 73 is recommended to verify programming.

Functional check in
target device
The screening temperature is far higher
than the storage temperature. Never
expose to 150
