PROGRAMMING TO THE EPROM ON THE MB89P689/W689
The MB89P/W689 is an OTPROM version of the MP89680 series.
1. Features
60-Kbyte PROM on chip
Options can be set using the EPROM programmer.
Equivalent to the MBM27C1001 in EPROM mode (when programmed with the EPROM programmer) and
supporting the 4-byte programming mode
2. Memory Space
Memory space in each mode such as 60-Kbyte PROM, option area is diagrammed below.
3. Programming to the EPROM
In EPROM mode, the MB89P689 functions equivalent to the MBM27C1001. 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.
When the operating ROM area for a single chip is 60 Kbytes (1000
H
to FFFF
H
) the PROM can be programmed
as follows:
Programming procedure
(1) Set the EPROM programmer to MBM27C1001.
(2) Load program data into the EPROM programmer at 1000
H
to FFFF
H
.
Load option data into addresses 0FE4
H
to 0FFC
H
of the EPROM programmer. (For information about each
corresponding option, see “8. Setting OTPROM Options.”)
(3) Program to 0FE4
H
to 0FFC
H
and 1000
H
to FFFF
H
with the EPROM programmer.
