s PROGRAMMING TO THE EPROM ON THE MB89P637

The MB89P637 is an OTPROM version of the MB89630 series.

1. Features

• 32-Kbytes PROM on chip

• Options can be set using the EPROM programmer.

• Equivalency to the MBM27C256A in EPROM mode (when programmed with the EPROM programmer)

3. Programming to the EPPROM

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 (8007H to FFFFH) the EPROM can be programmed

as follows:
