8-bit Proprietary Microcontroller

Fujitsu 

MB89670/A Series

3. Programming to the EPROM

In EPROM mode, the MB89P677A 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 0007H to 7FFFH (note that addresses 8007H to FFFFH

while operating as a normal operating mode assign to 0007H to 7FFFH in EPROM mode).

Load option data into addresses 0000H to 0006H of the EPROM programmer. (For information about each

corresponding option, see “7. Bit Map for PROM 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.

Program, verify

Aging

+150°C, 48 Hrs.

Data verification

Assembly

5. Programming Yield

All bits cannot be programmed at Fujitsu shipping test to a blanked OTPROM microcomputer, due to its nature.

For this reason, a programming yield of 100% cannot be assured at all times.

Note: Depending on the EPROM programmer, inserting a capacitor of about 0.1 µF between VPP and VSS or

VCC and VSS can stabilize programming operations.
