MB90650A Series
1. Program Mode
2. Programming Procedure
Note: The mask ROM products (MB90653A, MB90652A) does not support EPROM mode. Data cannot, therefore,
(1) Set the EPROM programmer to MBM27C1000/1000A.
(2) Load program data into the EPROM programmer at 00000
Note that ROM addresses FE0000
00000
The 00 bank PROM mirror is 48 Kbytes. (This is a mirror for FF4000
(3) Mount the MB90P653A on the adapter socket, then fit the adapter socket onto the EPROM programmer.
(4) Start programming the program data to the device.
(5) If programming has not successfully resulted, connect a capacitor of approx. 0.1 F between V
PROGRAMMING FOR MB90P653A
In EPROM mode, the MB90P653A functions equivalent to the MBM27C1000/1000A. This allows the EPROM
to be programmed with a general-purpose EPROM programmer by using the dedicated socket adapter (do not
use the electronic signature mode).
When shipped from Fujitsu, and after each erasure, all bits (128 K
state. Data is written to the ROM by selectively programming “0” into the desired bit locations. Bits cannot be
set to “1” electrically.
be read by the EPROM programmer.
When mounting the device and the adapter socket, pay attention to their mounting orientations.
