3. Programming to the PROM

In EPROM mode, the MB89P665A functions equivalent to the MBM27C256A. This allows the PROM to be

programmed with a general-purpose EPROM programmer (the electronic signature mode cannot be used) by

using the dedicated socket adapter.

• Programming procedure

(1) Set the EPROM programmer to the MBM27C256A.

(2) Load program data into the EPROM programmer at 4000H to 7FFFH (note that addresses C000H to FFFFH

while operating as a single chip assign to 4000H to 7FFFH in EPROM mode).

Load option data into addresses 3FF0H to 3FF6H of the EPROM programmer. (For information about each

corresponding option, see “8. Setting OTPROM Options.”)

(3) Program with the EPROM programmer.

4. Recommended Screening Conditions

High-temperature aging is recommended as the pre-assembly screening procedure for a product with a blanked

OTPROM microcomputer program.
