s PROGRAMMING TO THE EPROM ON THE MB89P689/W689

The MB89P689/W689 is an OTPROM version of the MP89680 series.

1. Features

• 60-Kbyte PROM on chip

• Options can be set using the EPROM programmer.

• Equivalent to the MBM27C1001 in EPROM mode (when programmed with the EPROM programmer) and

supporting the 4-byte programming mode

2. Memory Space

3. Programming to the EPROM

In EPROM mode, the MB89P689 functions equivalent to the MBM27C1001. 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 60 Kbytes (1000H to FFFFH) the PROM can be programmed

as follows:

• Programming procedure

(1) Set the EPROM programmer to MBM27C1001.

(2) Load program data into the EPROM programmer at 1000H to FFFFH.

Load option data into addresses 0FE4H to 0FFCH of the EPROM programmer. (For information about each

corresponding option, see “8. Setting PROM Options.”)

(3) Program to 0FE4H to 0FFCH and 1000H to FFFFH with the EPROM programmer.
