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
copies)
PROM PROGRAMMING METHOD
The built-in PROM of the blank One Time PROM version and built-
in EPROM version can be read or programmed with a general-
purpose PROM programmer using a special programming
adapter.
Package
100P6S-A
100D0
Name of Programming Adapter
PCA4738F-100A
PCA4738L-100A
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 writing, the procedure shown in Figure
XC-1 is recommended to verify programming.
Programming with
PROM Programmer
Screening (Caution)
(150°C for 40 hours)
Verification with
PROM Programmer
Functional check in target device
Caution : The screening temperature is far higher than
the storage temperature. Never expose to
150°C exceeding 100 hours.
