PRELIMINARY
Notice: This s not a final specification.
Some parametric imits are subject to change.
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)
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.

Name of Programming Adapter
PCA7438F-80A
PCA7438L-80A
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 72 is recommended to verify programming.
