3. Programming to the EPROM

In EPROM mode, the MB89P173 and MB89P175A 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 (MB89P173)

(1) Set the EPROM programmer for the MBM27C256A.

(2) Load program data into the EPROM programmer at 6000H to 7FFFH (note that addresses E000H to 0FFFFH

while operating as a single chip correspond to 6000H to 7FFFH in EPROM mode).

(3) Program the data to the EPROM with the EPROM programmer.

• Programming procedure (MB89P175A)

(1) Set the EPROM programmer for the MBM27C256A.

(2) Load program data into the EPROM programmer at 4000H to 7FFFH (note that addresses C000H to 0FFFFH

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 “7. Setting OTPROM Options (MB89P175A Only).”)

(3) Program the data to the EPROM 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.

5. Programming Yield

Due to its nature, bit programming test can’t be conducted as Fujitsu delivery test. For this reason, a programming

yield of 100% cannot be assured at all times.
