LC86P7148

No.6692-4/21

How to use

(1) Specification of option

The LC86P7148 must be programmed after specifying option data.

The option is specified by “SU86K.EXE”.

The

specified option file and the file created by our macro assembler “M86K.EXE” are linked by our linkage loader

“L86K.EXE” which creates .HEX file, then the option code is put in the option specified area (0FF00H to 0FFFFH) of

its .HEX file.

(2) How to program for the EPROM

The LC86P7148 can be programmed by EPROM programmer with attachment ; W86EP7148Q

• “27512 (Vpp=12.5V) Intel high speed programming” mode available.

The address must be set to “0 to 0FFFFH” and a

jumper (DASEC) must be set to ‘OFF’ at programming.

(3) How to use the data security function

“Data security” is the disabled function to read the data of the EPROM.

The following is the process in order to execute the data security.

1. Set ‘ON’ the jumper of attachment.

2. Program again.

Then EPROM programmer displays the error.

The error means normally activity of the data

security.

It is not a trouble of the EPROM programmer or the LSI.

Notes

• Data security is not executed when the data of all address have ‘FFH’ at the sequence 2 above.

• The programming by a sequential operation “BLANK=>PROGRAM=>VERIFY” cannot be executed data security at the

sequence 2 above.

• Set to ‘OFF’ the jumper after executing the data security.
