PROGRAMMING TO THE EPROM ON THE MB89P955
The MB89P955 is an OTPROM version of the MB89950 series.
1. Features
16-Kbyte PROM on chip
Equivalency to the MBM27C256A in EPROM mode (when programmed with the EPROM programmer)
2. Memory Space
Memory space in EPROM mode is diagrammed below.
3. Programming to the EPPROM
Functions equivalent to the MBM27C256A can be used in the MB89P955 EPROM mode. Accordingly, the user
can write data with a general-purpose EPROM writer by using a dedicated adapter. Note that the electrical
signature mode is not supported.
Programming procedure
(1) Set the EPROM writer for the MBM27C256A.
(2) Load program data from 4000
H
to 7FFF
H
of the EPROM writer (Note that 0C000
H
to 0FFFF
H
in the operation
mode are equivalent to 4000
H
to 7FFF
H
in the EPROM mode).
Load option data from 3FF0
H
to 3FF6
H
of the EPROM writer (See Bit Map on the next page for the
correspondence to each option).
(3) Write the data with the EPROM writer.
