PROGRAMMING TO THE EPROM ON THE MB89P825
The MB89P825 is an OTPROM (one-time PROM) version for the MB89820 series.
1. Features
16-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 EPROM mode is diagrammed below.
3. Programming to the EPROM
In EPROM mode, the MB89P825 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.
(1) Set the EPROM programmer to the MBM27C256A.
(2) Load program data into the EPROM programmer at 4000
H
to 7FFF
H
(note that addresses C000
H
to FFFF
H
while operating as a single chip assign to 4000
H
to 7FFF
H
in EPROM mode).
Load option data into addresses 3FF0
H
to 3FF5
H
of the EPROM programmer. (For information about each
corresponding option, see “7. OTPROM Option Bit Map.”
Programming procedure
(3) Program with the EPROM programmer.
