(1) Option

The option data is created by the option specified program “SU86K.EXE”. The created option data is linked to the
program area by linkage loader “L86K.EXE” .

(2) ROM space

LC86E7248 and LC8672 00 series use 256 bytes that is addressed on 0FF00H to 0FFFFH in the program memory as the
option specified data area. These program memory capacity are 49152 bytes that is addressed on 0000H to 0BFFFH.

How to use

(1) Specification of option

Programming data for PROM of the LC86E7248 is required.
Debugged evaluation file (EVA file) must be converted to an INTEL-HE X formatted file (HEX file) with file converter
program, EVA2HEX.EXE. The HEX file is used as the programming data for the LC86P6548.

(2) How to program for the EPROM

The LC86E7248 can be programmed by EPROM programmer with attachment ; W86EP7248Q

• Recommended EPROM programmer

Productor EPROM programmer
Advantest R4945, R4944, R4943

Andou AF-9704
AVAL PKW-1100, PKW-3000

Minato electronics MODEL1890A

• “27512 (Vpp=12.5V) Intel high speed pro gramming” mode available. Th e addre ss 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.

(4) How to eliminate

The programming data can be erased by using the EPROM eraser.

(5) Shielding

The UVEPROM (ultraviolet erasable programmable ROM) is in it. Put the seal on the window in use.
