DATA REQUIRED FOR MASK ORDERS/ROM PROGRAMMING METHOD
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)
ROM 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. 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 31 is recommended to verify programming.
