LC86E5032
Writing to EPROM
(1) Specification of options
Programming data for the LC86E5032's EPROM is required.
The debugged evaluation file (EVA file) must be converted to an INTEL-HEX format file (HEX file) with the file converter
program, EVA2HEX.EXE. The HEX file is used as the programming data for the LC86E5032.
(2) How to write data to EPROM
The LC86E5032 can be programmed by a general-purpose EPROM programmer with attachments W86EP5032D and
W86EP5032Q.

• "27512 (Vp-p = 12.5 V) Intel high-speed programming" mode should be used. The address must be set to "0000H to
7FFFH" and the jumper (DASEC) must be set 'OFF' at programming.
(3) How to use the data security function
"Data security" is a function to prevent the EPROM data from being read.
Instructions on using the data security function:
1. Set the jumper of the attachment 'ON'.
2. Attempt to program the EPROM. The EPROM programmer displays an error. The error is a result of normal activity
of the data security feature. This is not a problem with the EPROM programmer chip.
Notes
• The data security function is not carried out when the data of all address contain 'FF' at step 2 above.
• Data security cannot be executed when the sequential writing operation of programming
"BLANK=>PROGRAM=>VERIFY" is used at step 2 above.
• Set the jumper 'OFF' after the execution of data security.
(4) Erasing data
Use a general-purpose EPROM eraser to erase the written data.
(5) Shielding
The UVEPROM (ultraviolet erasable programmable ROM) is incorporated in the IC. Cover the window of the IC with a seal
in use.
