MB89640 Series

PROGRAMMING TO THE EPROM ON THE MB89P647
The MB89P647 is an OTPROM version of the MB89640 series.
1. Features
32-Kbyte PROM on chip
Options can be set using the EPROM programmer.
Equivalency to the MBM27C256A in EPROM mode (when programmed with the EPROM programmer)
2. Memory Space
Memory space in each mode such as 32-Kbyte PROM, option area is diagrammed below.
Precautions
(1) The program area of the MB89P647 is 7 bytes smaller than that of the MB89PV640 and MB89647 to provide
an option area. Note this point during program development.
(2) During normal operation, the option data is read when the option area is read from the CPU.
3. Programming to the EPROM
In EPROM mode, the MB89P647 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 0007
H
to 7FFF
H
(note that addresses 8007
H
to FFFF
H
while operating as internal ROM mode assign to 0007
H
to 7FFF
H
in EPROM mode).
Load option data into addresses 0000
H
to 0006
H
of the EPROM programmer. (For information about each
corresponding option, see “7. Setting OTPROM Options.”)
(3) Program with the EPROM programmer.
