LC86E7248
No.6749-4/19
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-HEX 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

AVAL
PKW-1100, PKW-3000
Minato electronics
MODEL1890A
• “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.
(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.
