PROGRAMMING TO THE EPROM ON THE MB89P637
The MB89P637 is an OTPROM version of the MB89630 series.
Memory space in each mode is illustrated below.
In EPROM mode, the MB89P637 functions equivalent to the MBM27C256A. This allows the PROM to be
programmed with a general-purpose EPROM programmer by using the dedicated socket adapter.
However, the electronic signature mode cannot be used.
When the operating ROM area for a single chip is 32 Kbytes (8007
as follows:
