APPENDIX
D.1 Programming Specifications for One-time PROM and
EPROM Microcontrollers
In EPROM mode, the MB89P955 function is equivalent to the MBM27C256A. This allows
the PROM to be programmed with a general-purpose EPROM programmer by using the
dedicated adaptor. Note that the electronic signature mode cannot be used.
