s PROGRAMMING TO THE EPROM ON THE MB89P627
The MB89P627 is an OTPROM version of the MB89620 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.
3. Programming to the EPROM
In EPROM mode, the MB89P627 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 (8006H to FFFFH) the PROM can be programmed
as follows:
Programming procedure
(1) Set the EPROM programmer to the MBM27C256A.
(2) Load program data into the EPROM programmer at 0006H to 7FFFH (note that addresses 8006H to FFFFH
while operating as a single chip assign to 0006H to 7FFFH in EPROM mode).
Load option data into addresses 0000H to 0005H of the EPROM programmer. (For information about each
corresponding option, see “4. Setting OTPROM Options.”)
(3) Program to 0000H to 7FFFH with the EPROM programmer.
