s PROGRAMMING TO THE EPROM ON THE MB89P131

The MB89P131 is an OTPROM version of the MB89131.

1. Features

• 4-Kbyte PROM on chip

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

2. Memory Space

Memory space in EPROM mode is diagrammed below.

3. Programming to the EPROM

In EPROM mode, the MB89P131 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.

• Programming procedure

(1) Set the EPROM programmer for the MBM27C256A.

(2) Load program data into the EPROM programmer at 7000H to 7FFFH (note that addresses F000H to FFFFH

while operating as a single chip correspond to 7000H to 7FFFH in EPROM mode) .

(3) Program with the EPROM programmer.
