MB89680 Series
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
Memory space in each mode such as 60-Kbyte PROM, option area is diagrammed below.
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.
