PROGRAMMING TO THE EPROM ON THE MB89P657A
The MB89P657A is an OTPROM version of the MB89650A series.
• 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)
Memory space in each mode such as 32-Kbyte PROM, option area is diagrammed below.
In EPROM mode, the MB89P657A 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.
When the operating ROM area for a single chip is 32 Kbytes (8006
as follows:
• Programming procedure
(1) Set the EPROM programmer to the MBM27C256A.
(2) Load program data into the EPROM programmer at 0006
(3) Program to 0000
while operating as a single chip assign to 0006
Load option data into addresses 0000
corresponding option, see “7. Setting OTPROM Options.”)
